Abstract
The invention discloses a method for producing feed protein sources by using water hyacinth and belongs to the field of biological resource feed processing. The method mainly comprises the following steps that: collected and harvested fresh water hyacinth is crushed into thick pulp; the press filtering is carried out to obtain filter slag and filter liquid; a proper amount of (NH)2SO4, KH2PO3, green trichoderma and endomycopsis fibuligera yeast are added into the filter slag, and the materials are sealed for fermentation for 3 to 4 days; the filter liquid is subjected to self fermentation for 3 to 4 days, and the supernate and the precipitates are separated; the supernate is used for culturing unicellular algae; the filter liquid self fermentation precipitates and the fermentation liquid filter slag are simultaneously dried to a state with the moisture content lower than or equal to 11 percent, the feed protein sources are obtained, and the feed protein sources can be packed for sale. The water hyacinth which is called as one of the ten host harmful grass is utilized for producing the feed protein sources, the raw materials are rich and are easy to obtain, in addition, harmful materials are changed into useful materials, the product protein content reaches higher than 26 percent, and the shortage of feed protein lack in China can be overcome.
Description
Technical field
The present invention relates to a kind of method of utilizing water hyacinth to produce the forage protein source, belong to the field of feed processing of biomass resource.
Background technology
Water hyacinth has another name called Eichhornia crassipes, is Pontederiaceae, the phoenix eyes Nelumbo, be the perennial root herbaceous plant that swims, having asexual and zoogamy function concurrently, especially take vegetative propagation as main, is one of the fastest water plant of growth and breeding in the world, under optimum conditions, Population Growth and recovery capability are extremely strong, and can increase by 20% ~ 30% biomass every day, and the general per hectare water surface is produced about 1000 tons of bright grass per year, amount to about 50 tons of dries, high person's per hectare even can produce bright grass per year and reach 3000 tons.Because the Eichhornia crassipes growth breeding is fast, normal large tracts of land covers the water surface, cause the obstruction of river course lake surface, affect shipping, irrigation and drainage and flood discharge, because too high density causes fierce intraspecific competition, cause perish in addition, ruin water quality, the aggravation body eutrophication, thus other hydrobiological safety endangered, destroy fish production and the ecological balance.Given this, water hyacinth is listed in the hat of ten universally acknowledged large evil grass, and is classified as the second place of hundred in the world " biological killer's list " by " World Conservation Union ".
In recent years, 19 provinces and cities in China North China, East China, Central China, south China and southwest, especially with provinces and cities such as Guangdong, Yunnan, Jiangsu, Zhejiang, Fujian, Sichuan, Hunan, Hubei and Shanghai serious water hyacinth harm all can occur every year, the whole nation is because the direct economic loss that causes of water hyacinth reaches 80 ~ 10,000,000,000 yuan, wherein only one of control expense just up to 5 ~ 1,000,000,000 yuans.The harm that spreads for the control water hyacinth, main employing machinery is salvaged at present, chemical herbicide is killed and 3 kinds of methods of biological control, it is high wherein to salvage disposal cost, spends 1,900 ten thousand yuan such as District of Shanghai in 2002 and salvages 1,680,000 tons of water hyacinths, and total control expense reaches 8,000 ten thousand yuan; Chemical herbicide is killed and can be caused secondary harm to environment; Biological control takes effect slowly, and effect is unstable.Therefore, carry out the hyacinth resource utilization utilization, changing harmful to treasure is the basic method that solves its harm.
China is cultivation big country in the world, the shortage of protein raw materials is particularly serious, the external interdependency of animal husbandry and feed industry protein feeds raw material surpasses 70%, it is global protein raw material importer of last resort, need 3,500 ten thousand tons of soybean of import, 1,200,000 tons of protein resources such as fish meal every year, be worth about 1,500 hundred million yuan of RMB.Water hyacinth contains higher nutritive value, crude protein content in the hay is near 20%, and composition of amino acid is suitable, is better than rice protein and soybean protein, therefore utilizing water hyacinth to produce the forage protein source is extensive recycling water hyacinth, the effective way that changes harmful to treasure.
Summary of the invention
The objective of the invention is to spread the significant damage of bringing to society for a large amount of procreation of the long-term in short supply and water hyacinth in China forage protein source, provide recycling water hyacinth a kind of easy and simple to handle, with low cost to produce the method in forage protein source.
Technical scheme of the present invention: a kind of method of utilizing water hyacinth to produce the forage protein source, the method includes the steps of:
(1) the fresh water cucurbit of gathering is ground into underflow;
(2) press filtration separates filter residue and filtrate;
(3) in filter residue, add an amount of inorganic salts and composite bacteria, the mixing fermentation;
(4) sealing filtrate is from fermentation, separation of supernatant and sediment;
(5) supernatant is used for cultivating unicellular alga;
(6) with filtrate from ferment sediment with the fermentation filter residue and drying to water content≤11% the forage protein source can pack sale.
It is further characterized in that: the ratio of step (2) press filtration gained filtrate and filter residue weight is close to 7:3.
Add (NH in every kilogram of filter residue in the step (3)

8Individual, the Polypropylence Sheet fermentation is 3 ~ 4 days on the bonnet that stirs, and the fermentation material temperature control is at 30 ~ 55 ℃.
Production technology of the present invention and product have the following advantages:
Synthetic protein and nucleic acid were required when 1, Easy dosing, filter residue fermentation only added a small amount of inorganic salts for the fermentation fungus grown, and filtrate is adopted from fermentation process precipitation leaf protein;
2, energy consumption is low, has removed in the water hyacinth nearly 70% moisture by press filtration, is convenient to drying, can be dry by airing at Clear Days Summer.
3, fermentation period is short, only needs 3 ~ 4 days.
4, product quality is high, and protein content brings up to 26.41% by 19.97%.
5, product is convenient to store and sell.
