Abstract

Said invention relates to the utilization of feces of human being and animals when they live in space for long time and waste of animal and crops to breed fly maggot, then using the fly maggot in space and nonedible part of space crops to breed animal to realize waste recirculation in space closed environment and high-effectively produce edible various nutrient food

Description

Raise the food source of fly maggot the space human residential environment as the human and animal

Technical field that the present invention belongs to:

A kind of production method of aerospace food in the long-term extraterrestrial life of the mankind.Particularly be implemented in the effective ways that efficiently are converted into food in the enclosed environment by whole waste materials.

Background technology:

Human space travel still is confined to near-earth orbit so far, and the supply of food is all from the earth.Yet the mankind will leap far more from now on.Removing celestial body far away (for example more than the several years) or go the immigrant of other celestial bodies, is a big problem to cosmonaut and celestial body immigrant's food supply.Even the calculated Mars travelling of the U.S. at present also needed for 3 years, the cost that is transported by emission on the earth has reached 21800 dollars of per kilograms, and this expensive must being difficult to bears.

Because the enormousness weight of this based food supply and expensive cost, to remote space travel, it is impossible to have become from earth supply.So with the country headed by the U.S., researching and developing the life-support systems (being called for short the closed loop life support system) of the closed loop of a self-loopa victual, water, air, promptly utilize in airship or the celestial body immigrant living environment, the waste material recycle again after treatment human and plant produces, it is used that the food of Chan Shenging, air, water can be kept the long-term life of the mankind and plant again, needn't lean on the earth to supply with again.

NASA (NASA) exploitation at space plantation crop system, as wheat, soybean, potato, it can produce edible starch, vegetable protein, vitamin etc., and it can absorb CO under illumination ₂Discharge oxygen, can recycle waste water and part slop.But its nutrition is incomplete, and the growing space is big, and the cycle is long, and efficient is low.Refuse can only little part recycle.NASAization is taken the so-called artificial little earth " No. two, biosphere " of 1.5 hundred million dollars of constructions in the State of Arizona, US desert, it mainly is the sealing system of kind of plant, eight self-sufficient therein lives more than a year of scientist are arranged, abominable because of environment in enclosing at last, can't support the family again, can only walk out biosphere, and declare this One's cake is dough.It has exposed depends the crop-planting system alone aerospace food is provided, and is the condition that can not satisfy the advanced closed loop life support system that NASA proposes.At present, the recirculation of water and air more easily solves, and the most difficult is the recirculation of food, and wherein the most thorny is the utilization again of human feces.U.S. NASA about university and other research institutions, studied the technology that reclaims utility from people's ight soil, yet still nobody knows so far, how could directly human body waste be changed into little good to eat but nutritious food.The closed loop life support system of being studied at present, cosmonaut's food still are conceived to by obtaining in the human grain of planting in airship.The human excrement and urine is main only to produce CO as the fertilizer of plant and the back of burning ₂Use for plant respiration.So far the closed loop life support system that NASA pursued also realizes far away.

In fact, the nutrition intake rate of human body is not high, and many nutrition will be discharged from people's stool and urine.The cosmonaut can cause the serious malnutrition of health in the space microgravity environment, lose the material of needed by human such as a large amount of calcium, and they are mainly discharged from stool and urine, and mechanism wherein is also not clear so far.Can affirm that in the cosmic space, the stool and urine of human body is valuable nutrient source, it can not be considered waste material, and its nutrition should become food with the effective method recovery and feed back to human body again.To reach the requirement of the advanced life support system of NASA.

Content of the present invention:

The present invention aims to provide a kind of new method, make the human ight soil that utilizes self (cosmonaut or celestial body immigrant) and animal at space, and the not edible of space crop and animal part (internal organ of wheat bran, bean dregs, crop cauline leaf and edible animal, bone, fur etc.) mixing is raised fly maggot as feed, fly maggot can realize becoming ight soil efficiently and above-mentioned waste material is the high-protein nutrient material, make food source with fly maggot again, for human directly edible; Or remake the feed of animal, raise bird, aquatic animal, two dwell animal and livestocks, with these animals and eggs thereof in the space for human edible.Use the method, the crop-planting system that successfully develops in conjunction with present U.S. NASA just can realize the space closed loop life support system that NASA proposes perfectly again.

Specific implementation method:

Fly maggot is a screwworm.The kind of fly is a lot of on the earth.Basically fly has all that to have a liking for excrement and change excrement be the characteristics of high-protein nutrient material.Being example with the housefly among the present invention, is because it has extremely strong survivability, very short growth cycle.Under high-density state, be easy to raise.Its growth is fast, high production.Avirulence is difficult for falling ill, operation and device simple.Raising fly maggot has been proven technique, and fly maggot happiness coprophagy is just preferred human excrement especially.After raising in 4 days can be put on weight about 300 times, this is to be converted into edible protein through ight soil in the world at present to fly maggot, the most efficiently one of approach from hatching.Many in the world countries handle the ight soil of animal in the mode of raising fly maggot, and fly maggot that grows up to or fly pupa remake that high protein feed keeps fowls, domestic animal, birds and aquatic animal, have all obtained the effect of efficient high yield.The aseptic odorless of residue behind the foster maggot can be made senior fertilizer.So not only save feed, and efficiently handled the animal wastes of contaminated environment, reached the purpose that turns waste into wealth.

The present invention cultures fly maggot in the space human residential environment, people's (cosmonaut and space resident) ight soil and other all biological wastes directly efficiently are converted into human needs's high protein and other nutriments, make main feed with fly maggot again, feed other animals, with this food as the mankind in the space.In conjunction with the space crop-planting system that NASA has succeeded in developing, can reach of the requirement of the desired closed loop life support system of NASA to food.

The nutrition of § 1 fly maggot

Fly maggot powder is that barreling became powder after fresh fly maggot drying was handled, and the weight after the processing is 1/3～1/4 of fresh maggot weight.Flyblow albumen powder is that fly maggot powder is purified through the acid precipitation.

By table 1 as seen, the fly maggot powder crude protein content is 54～63%, and fat is 11-17%, is high than fish meal all.Seen that by table 2 unsaturated fatty acid accounts for 68.2% in the fly maggot powder, essential fatty acid accounts for 36%, is mainly linoleic acid.Contain more linoleic acid plus linolenic acid in the general vegetable oil, its nutritive value is than animal fat height.Though the maggot powder is the animal class, its contained essential fatty acid is all than arachisoil and vegetable seed innage.The ratio of its saturated fatty acid and unsaturated fatty acid is 40%, and this point is excellent more than ox, sheep, pig and chicken.Vitamin A, D and B family content are abundant especially in the fly maggot powder, particularly B ₁, B ₁₂Be respectively 15 times and 1800 times of milk.They lack in crop especially.

Remove in the fly maggot body and be rich in electrolyte element potassium, sodium, calcium outside the manganese, also contains the micro-element of a large amount of needed by human, as zinc, iron, manganese, copper, boron, phosphorus etc.

Find out by table 3, the abundant and collocation of the amino acid content of fly maggot powder rationally, its each amino acid content all is higher than fish meal, it must total amino acid content be 2.3 times of fish meal, wherein the content of methionine, phenylalanine, lysine is about 3 times of fish meal approximately.The reference value 40% that its TEAA E% all proposes above Food and Agricultural Organization of United Nations/World Health Organigation (FAO/WHO), its E/N also far surpasses the reference value 0.60 that FAO/WHO proposes.They are also far above the value of fish meal.

§ 2 fly blows are as the long term storage in food source

The present invention proposes to raise circulate waste material in the extraterrestrial life environment of fly maggot, and polytrophic fly maggot again Edible for humans and animals. Propose again by the earth zone fly blow to space, thereby avoided complicated foster fly operation. Namely only support maggot and do not support fly. Here preserved food products is actually preserved food products " source "---fly blow. Its weight The amount only be its output food (fly maggot) weight 1/300. So fly away from terrestrial time at airship, need carry The fly blow weight and volume all is very little, and each astronaut navigates by water and only need carry 5 kilograms of fly blows in 10 years as calculated Enough his food source supplies.

The technical problem of insect ovum long preservation under the ultralow temperature state is academicly solving. U.S.'s health The Lynch of university places liquid nitrogen container ultralow temperature long preservation with the fruit bat ovum like this, can reach 75～90% behind the rewarming The fly blow incubation rate. As long-term space flight and life, ultralow temperature long preservation fly blow is in the liquid nitrogen container Preserve the method in food source simple and feasible indefinite duration.

The raising of § 3 fly maggots

1, the preparation of fly-maggot feed (accounting for the percentage by weight of feed)

Cosmonaut and space resident's fresh stool and urine accounts for 65～75%; The inedible part of (with fly maggot feeding) animal fresh excreta and animal health accounts for 5～10%; The not edible of space crop partly (fresh wheat bran, bean dregs) accounts for 10～20%; Space crop cauline leaf accounts for 5-10% (cauline leaf need be broken into 2～5 millimeters long, and 1～2 millimeter of diameter shaft-like is to keep feed in-to-in aeration).

2, the processing of feed:

Above-mentioned feed is mixed, in 25～30 ℃ closed container,, handle with microwave or ultraviolet disinfection again through fermentation in 2～5 hours.The humidity of feed need remain on 60～70%.

3, raise the sterilization treatment of container: need with ultraviolet precompose sterilization treatment.

4, the inoculation of fly blow:

Fly blow is to take from superfreeze in liquid nitrogen after the aseptic fly blow that thaws.And with the fly blow of every kilopond feed inoculation 1～1.5 grammes per square metre in above-mentioned feed surface.

5, the condition of Si Yanging:

Rearing-box need be isolated from the outside, in case foul smell is excessive.The temperature inside the box need remain on 22～32 ℃, and air humidity is 60～70%.Air composition and human living in space environmental facies are together.The case domestic demand is ventilated, and wind speed is the 0.5-1.0 level, and keeps dark.

6, the structure of rearing-box and feeding process:

Raise the container of fly maggot, more much smaller than tellurian, this is owing under the space microgravity environment, must allow fly maggot contact closely with feed, otherwise the space is big, and they " are waftd ", and therefore fly maggot can be eaten less than feed.The yardstick of rearing-box is 40 * 40 * 10cm ³Be the seal casing of being made by non-toxic plastic, the maggot output alive of four days one-periods of each case is about 2 kiloponds.The inoculation fly blow needs 6～7 grammes per square metres.Every case is divided into three layers, is respectively 6cm, 2cm, 1cm height.Upper strata 6cm is thick to be feeder layer, piles feed and plants fly blow again.Middle level 2cm is thick, only puts wheat bran or bean dregs.The fly maggot on upper strata was raised through 4 days when ripe, and top of the upper layer illumination utilizes the characteristic of fly maggot lucifuge, and it is driven to the middle level.Stopped 3～4 hours in the middle level, only eat wheat bran or bean dregs, to get rid of the ight soil in the fly maggot body.Drive to lower floor with illumination, place wet wood chip or wet fine sand in the lower floor, containing ripe fly maggot, and it is directly edible or make fly maggot powder for letting animals feed to isolate ripe maggot with sieve method.Fly maggot was rushed to its hunger of lower floor's relief 3～4 hours, and purpose also is in order to remove the ight soil in its enteron aisle.Interlayer between three layers is to separate with metal gauze, and its width of mesh can allow fly maggot tighten health just at the right time and push through, and purpose is to remove the sticking thing of ight soil of its body surface.The feed on upper strata need stir once in per 12 hours, the too high and anoxic in case feed fermentation heats up, and need add fresh feed according to circumstances at the second, the three day.

Place breather pipe in three layers in case, wind speed remains on 0.5～1.0 grade.The outer stuffiness of whole rearing-box and case in case foul smell is excessive, is polluted the environment of human living.Breather pipe drains into foul smell in the deodorant liquid and filters out in the case.

Fly maggot is raised the food-residue after the maturation, is aseptic odorless, because fly maggot can be secreted sterilization material, so it can make the senior fertilizer of space crop.

Such circulation feeding process can be realized whole regeneration (zero waste material) of waste material.The fly maggot of producing can be accomplished aseptic.

§ 4 raises kind of a fly at space---the standby technology under emergency situation only

Need bigger cultured space and extra labour's equipment owing to raise kind of fly at space.So the present invention only stores fly blow with superfreeze, also can satisfy the demand of food source.Promptly only support maggot and do not support fly, only when the accident of fly blow forfeiture takes place, just need to support fly and breed this food source of fly blow at space.At ordinary times, maggot is about to ripe, can directly make feed for letting animals feed, or be processed into the maggot powder immediately.If do not kill ripe maggot, it gets final product pupa in a few hours.

1, fly blow is selected:

In order to obtain the special quality fly blow, the fly pupa of selection will guarantee that in each body weight be more than 18 milligrams.Fly blow is preferably taken from the 6th～10 day ovum that is produced.

2, stocking density:

Fly stocking density in extensive ground plant is 40000～60000/m ²But raise purpose only for laying eggs at space, thus only need a small amount of raising, with the collection fly blow.It also is enclosed becoming the fly rearging cage, and it is made by non-toxic plastic.If with two fly cages, the space of every cage is 40 * 40 * 40cm ³, becoming the fly activity space by every is 10cm ³Meter then can be supported 6000 pairs of flies, lays eggs in 10 days 1000 with every pair of fly, and every gram fly blow is about 12000～14000,400～500 grams of then can laying eggs in 10 days, and every days 40～50, the gram ovum can be produced the required fly blow amount of food every day for 5 cosmonaut completely.(5 * 6 grams=30 grams)

3, the feed of Si Yanging:

The feed ratio fly maggot of fly of laying eggs requires height, becomes fly happiness food fly maggot to stick with paste (fly maggot of will living grinds into pasty state) fortunately, and fly maggot stick with paste just can be self-sufficient at space.Its prescription is that 70% fly maggot is stuck with paste+30% wheat bran or bean dregs.

4, the method for Si Yanging:

Fly maggot is raised with aforesaid identical, when fly maggot after ripening in 4 days, allows it pupate in the wood chip of rearing-box lower floor, selects body weight to plant greater than the pupa of 18mg.Allow pupa at 24～32 ℃, under 60～70% humidity, the ventilation wind speed is 0.5～1.0 grade, keeps dark, and pupa was promptly sprouted wings through 5～7 days, becomes fly to sprout wings and can lay eggs in back 3 days, and the egg-laying season is about 30 days.Generally after 15 days, promptly kill into fly, stop to get ovum.

The raising temperature of fly, humidity and method for breeding:

Becoming the interior temperature of fly rearging cage is 24～30 ℃, and air humidity is 50～80%, is furnished with feed box in the cage, divide water-absorbing sponge, (sponge adhesive water and feed prevent in the microgravity environment with luring the sponge that lays eggs to be coated with the feed sponge, water and feed float in the air, so that supply to take food into fly.)。Lure and be coated with feed on the sponge block of laying eggs equally, in addition addition fly lower abdomen extract or fresh human excrement are as oviposition attractant.Lure the sponge block of laying eggs to sprout wings and to insert in back three days, changed above-mentioned three kinds of sponges once, can respectively collect one time fly blow morning and afternoon every day every 12 hours the one-tenth fly.Above-mentioned rearging cage needs to sterilize with disinfection by ultraviolet light before raising.The fly pupa needs with sprouting wings behind the disinfecting solution of potassium permanganate again.

The procedure of processing of § 5 fly maggot powders

The fly maggot of raising 4 days is made through following steps:

Separation → cleaning → filter does → grindings → centrifugal treating → pasteurization → homogeneous processings → spray drying (or lyophilisation, or vacuum desiccation) but → collection dry powder → packing → microwave treatment fly maggot powder long-term frozen preservation.

With the fly maggot powder of this processing method preparation, wherein detect negatively in per 100 grams of Escherichia coli, pathogenic bacteria do not detect.Total number of bacteria all is lower than the whole milk powder standard in every gram.Illustrate that it is that health is edible.The fly maggot powder outward appearance of making is the ecru powdery, and light taste is gentle, is milk, free from extraneous odour.

§ 6 animal experiments---make the feed of animal with fly maggot

Owing to comprise the nutrition of rich in protein, aliphatic acid and other various animal needs in the fly maggot body, the feeding experiment of countries in the world proves, fly maggot is made the animal feed, go to support bird, domestic animals and aquatic animal, all reached than conventional feed with the obvious high survivor's rate of the fish-meal of equivalent weight, growth rate, raw egg rate and breeding potential.

§ 7 usefulness fly maggot powders are for the edible history of human body

Fly maggot is for human edible having a long history.The major obstacle that edible fly maggot can't be promoted is to it is believed that its traditional concept of " dirty ".Promptly there is the edible record of fly maggot in China in bright, clear two generations, and the family feast of " meat bamboo shoot " is just arranged in the famous A Dream of Red Mansions.So far the famous dish that southern china is popular " granulation Egg custard ", meat bamboo shoot wherein, granulation all are fly maggots.The eight-treasure cake in Ancient Chinese generation also is to add the rice cake that ground rice is made with fly maggot powder, can control children's indigestion etc.In recent years, have in the society fly maggot is made restaurant's dish, make the report of seasonings or tropon human consumption.

§ 8 usefulness fly maggots are human edible for space as the main feed letting animals feed

1, the reason of letting animals feed:

The balanced nutritious composition of maggot powder, aseptic avirulence, taste is gentle, no specific peculiar smell.Fly maggot is easy to the high-density rearing, and the growth efficiency height is operated very simple.Only from its nutritive value and its special health care, with it in conjunction with space crop (maggot powder and flour mix back cook bread and other food), directly people are beyond affordability to make food with insect for making very much, lets alone with the ight soil raising fly maggot of oneself and has made food.

So the present invention finishes the crucial first step, by raising fly maggot, after converting the waste material of human faecal mass and space crop the fly maggot of high nutrition to efficiently, second step was to make the animal feed with fly maggot, and the egg that these animal and animals gave birth to of raising is as the space mankind's food.Domesticated animal mainly contains bird in the space, two dwell three kinds of class and aquatic animal classes.Here select for use egg to use quail, Rana castes beiana shaw and loach are example.

2, the reason that to select above-mentioned three kinds of animals be the space letting animals feed is, because of they have following common ground:

(1) feed all can be self-sufficient at space.They are all liked food fly maggot alive and make feed, and other auxiliary fodder are the not edible part of space crops such as wheat bran, bean dregs.In the young bird phase of these animals, young quail, tadpole and young loach all can maggot powder plus wheat brans, the bean dregs feeding, can add maggot alive after growing up and feed and raise.

(2) all having passed through preliminary space hatching and feeding experiment, though these space test purposes only are the ecology tests under microgravity environment, is not for it is done food production.But it has also proved the feasibility of raising them in space.

The interior cosmonaut of in February, 1999 Russian's Mir space station was once hatched 37 squealers with 60 quail eggs, even in the harsh environment of space intense radiation, had also supported ten.Frog to the Southern Africa on U.S. STS-47 space shuttle carries out embryology research, and the ovum that these frogs give birth in space has all been hatched small tadpole.Fish and fish-egg have also been carried out same successful test.The outstanding advantage of another of raising aquatic animals is, they were lived in water originally, had adapted to the agravic environment of this similar space in the water already, so their ecology in space is particularly taken food and bred, not influenced by microgravity environment at all.Fly maggot can be survived in water and be movable more than 24 hours, and edible fly maggot alive can be as convenient on earth in water for aquatic animal.

Shortcoming is a water source anxiety in the space.Have a large amount of freezing water on the recent findings Mars and the moon and exist, be developed some day, then can be very convenient on these celestial bodies with the fly maggot raising aquatic animals.

3, their ovum (quail egg, frog's egg and fish-egg) is by bringing on the earth, long preservation indefinitely under the ultralow temperature state of liquid nitrogen, and behind rewarming, all can hatch out.They also can oneself be bred in space environment and lay eggs.

4, theirs is small, and it is fast to grow, economical maturity and early sexual maturity, and the egg laying amount height, comformability is strong, anti-high-density rearing, premunition is strong, and these animals itself and eggs thereof all are high protein diets of low fat low cholesterol, features good taste, digestion easily.With the quail is example, and promptly laid eggs in the hatching back in 35～40 days usually, and laying rate is up to more than 80%, and quail egg and its weight ratio are 2.5～2.7 times of egg.Appetite is little, and feedstuff-egg ratio is 3: 1, its happiness food fly maggot alive, and the quail excrement is the feed that fly maggot is had a liking for food.

5, these animals breeding technology on earth all is ripe.

Other exceptional functions of § 9 fly maggot compositions: improve human body radioresistance and immunocompetence

In space; owing to lack the protection of picture earth atmosphere barrier; the intense radiation of various cosmic rayss is significantly to the injury of human body in space, for example minimizing of cosmonaut's leukocytic immunity cell, and it is to the carcinogenic factor of human body and the injury of fecundity etc.Resisting cosmic radiation is the important subject of NASA and countries in the world to the injury of human body, does not still have effective method so far.Test shows that edible fly maggot powder and maggot slurry can make animal and human's class improve radiation-resistant ability and immunologic function significantly.To the reduction that the patient of radiotherapy chemotherapy can obviously slow down leucocyte and immunocyte, the alopecia phenomenon also obviously reduces.So far to causing the effective ingredient of this function it be unclear that in the fly maggot body.But it has the important clinical meaning to reaching the mankind that live on the earth in the space.

Thus, a series of health foods be can develop, maggot powder or oral liquid made with fly maggot.Edible maggot powder can use conventional feed (to get a foothold or pluck with the cereal beans, or raise fly maggot with the effective constituents such as Chinese medicinal herbs of other functions of conventional feed compatibility, make fly maggot powder or oral liquid again, use for people's official ceremonial dress that keeps healthy, be used to improve the anti-radiotherapy chemotherapy ability of people, go up inevitable contact radioactivation to working and be subjected to the people in radiocontamination area all can use it.Also the effective constituents such as Chinese medicinal herbs of direct other functions of compatibility of fly maggot powder can be strengthened its function.In addition,, make product, same function is also arranged as its eggs, meat with the product of fly maggot letting animals feed.

The dosage of maggot powder, per day for adults are the pure fly maggot powder of per kilogram of body weight 0.3～1.0 gram.

§ 10 advantages

1, raises ight soil and the space work of human and animal in the fly maggot reusable edible living in space environment at space The not edible of thing and animal partly is the food source of high nutrition with it Efficient Conversion, thereby is implemented in space The life-support systems of closed loop in the living environment (self-loopa of food, empty G﹠W).

2, fly maggot can provide balanced abundant human body and the required nutrition of letting animals feed, as the nourishing healthy composition of rich in protein amino acid, aliphatic acid, vitamin, mineral matter rare element and many unknowns.It is with the space letting animals feed and plant plant, can satisfy and live in food nutrition demand human in the space environment for a long time.

3, the ovum of fly blow and other letting animals feeds can be stored under the nitrogen ultra low temperature state for a long time, and rewarming hatching at any time and growth, has solved the long term storage problem in food source.

4, fly maggot has extremely strong survivability, very short growth cycle and high-revolving growth and breeding potential.It can be day and night and ground high-density rearing continuously in season, to be implemented in efficient cheapness and self-centered food source production in the space.

5, fly maggot has born resistance against diseases, is difficult for falling ill, and it is convenient to raise.Raise fly maggot and carry out in the rearing-box of the very little sealed, sterile of volume, feeding process does not add any chemical substance, can not produce objectionable impurities or contaminated environment.The processing of fly maggot powder also is aseptic and no chemical substance, thus eat for human again with its letting animals feed, or directly for human edible, all be safe.

6, raising fly maggot and use the fly maggot letting animals feed, all is proven technique on earth, goes on this basis when raising in the space again, just can change expense small investment and time.They only need simple equipment and operative technique, and the processing of food and storage also are easy to be little with investment, so it can make the production and supply cost minimization of food in the space.

7, edible fly maggot composition can improve human body radioresistance and immunologic function, and a series of be basic health food with the fly maggot composition and with the edible animal that fly maggot is raised thereby can develop.
