Description
Technical field
The invention belongs to food processing technology field, be specifically related to a kind of a kind of prepare dietary fiber with marc for raw material and do
Method of powder and products thereof.
Background technology
Along with World Economics and the high speed development of industry, living standards of the people increase substantially, and diet is increasingly fine, because of battalion
The all ciril diseases supporting superfluous and nutritional disorder and produce, as diabetes, cardiovascular and cerebrovascular disease, obesity, intestinal cancer, constipation etc. are tight
Ghost image rings human health.Therefore there is regulation function of human body, prevent disease and sanatory functional food from having enjoyed pass
Note.Dietary fiber has prominent health care as the seventh-largest nutrient, is increasingly becoming the focus that nutritionist is paid close attention to.Meals
Food fiber can be divided into water soluble dietary fiber and the big class of water insoluble dietary fiber two by dissolubility.Dietary fiber by sources divide and
Soybean dietary fiber, corn dietary fiber, wheat-bran dietary fiber etc. can be divided into.The major function of water soluble dietary fiber is to subtract
Cholesterol levels in insufficiency of blood liquid, regulates blood sugar level, thus reduces cardiopathic danger, improve diabetes, and its source is main
Being water fruits and vegetables, Semen sojae atricolor and Herba bromi japonici etc., it includes the hydrocolloid mass such as pectin and part hemicellulose.Water-insoluble meals
Fiber major function is to expand, and can regulate the function of intestinal, prevent constipation, keep big gut health, and it mainly includes cellulose, wood
Quality and part hemicellulose etc..
Western developed country just sets about the research and development to dietary fiber as far back as the seventies, and American and Britain, moral, method are formed
Certain industry size, and occupy a tiny space at food products market.What the Japanese eighties, later-stage utilization water soluble dietary fiber was made
Beverage includes soda pop, lactic acid beverage and fruit juice etc..The external dietary fiber studied mainly has 6 big classes: corn, beans,
Fruit and vegerable, microbial polysaccharide and other natural fibers and synthesis, semisynthetic fibre, count more than 30 kind, is wherein applied to raw
Produce existing more than 10 kinds.At present, dietary fiber application in food is also had and studies widely by China.Especially in beverage and breast system
Application in product, China has produced liquid prandial fibre milk and the patent of relevant liquid form product thereof, and has pointed out dietary fiber
Addition in liquid milk is 7.22-22.4kg/t.Dietary fiber is added in Yoghourt by part researcher, significantly
Change mouthfeel and the rheological behavior of Yoghourt.
Marc refers to that the fruit of plant is passing through squeezing, after extracting its juice or oil content, remaining solid portion,
Include peel, sarcocarp, really seed, carpopodium etc..Common fruit has Fructus Vitis viniferae, Fructus Canarii albi, Fructus Mali pumilae, Li Guo, Fructus Persicae, pear etc..At present,
Marc acts on the most especially, can only abandon or retain and make compost and feedstuff is used, and resource develops low.
Summary of the invention
For the deficiencies in the prior art, it is desirable to provide one prepares meals with processing fruits by-product marc for raw material
The method of food fiber dry powder, this dietary fiber dry powder can be directly as high-quality dietary fiber supplement, it is also possible to directly make meals
Food fiber functional nutrient preparation such as buccal tablet, capsule, effervescent tablet etc., or be added in staple food directly as food additive, as
Bread, steamed bread, rice, noodles etc., or it is added on breakfast food of cake, cookies, puffed food, health beverage and instant type
In product, have a extensive future.
Concrete, the method preparing dietary fiber dry powder for raw material with marc of the present invention, comprise the following steps:
1) pre-treatment: by marc remove impurity, pulverizing, crosses 100 mesh sieves, obtains fruit fine powder；
2) defat: water intaking fruit fine powder, adds the hexanol of fruit fine powder volume 4-6 times, soaks under conditions of temperature is 50-80 DEG C
Carry 2-5h, filter isolated filtrate and filtering residue, by filter residue and drying, obtain defat material；
3) enzymolysis: extracting degreasing material, adds the distilled water of defat volume of material 15-25 times, regulates pH=5.5-6.5, adds defat
The protease of weight of material 3-6%, enzymolysis 30-60min under the Ultrasonic Conditions that temperature is 30-50 DEG C, filters isolated filter
Liquid and filtering residue；Take filtering residue, add the distilled water of filtering residue volume 15-25 times, regulate pH=4.5-5.0, add filtering residue weight 3-8%
Cellulase, enzymolysis 30-60min under the Ultrasonic Conditions that temperature is 30-50 DEG C, filters isolated filtrate and filtering residue；Will
Twice filtrate merges, and obtains enzymolysis solution；
4) inactivation: by enzymolysis solution steam inactivation 8-15min under conditions of temperature is 95-105 DEG C, be cooled to room temperature；
5) dietary fiber extracts: is placed in Rotary Evaporators by the enzymolysis solution after inactivation, is 0.05-0.08Mpa, temperature in pressure
For being concentrated into the 1/3-1/4 of original volume under conditions of 50-60 DEG C；Calculate with enzymolysis solution volume after concentrating, add 3-5 times of volume
95% ethanol, stands 3-8h after mixing, filter isolated filtrate and precipitation material, be placed in dehydrator by precipitation material and dry and wave
Send out ethanol, be subsequently placed in vacuum freeze drier, in temperature for-30～-20 DEG C, vacuum be under conditions of 30～50Pa cold
The dry 5-15h of lyophilizing, obtains described dietary fiber dry powder.
Another object of the present invention is to provide a kind of dietary fiber dry powder using said method to be prepared.
The present invention prepares dietary fiber dry powder with the side-product marc after processing fruits for raw material, and technique is simple, it is easy to behaviour
Making, and low in raw material price, be easy to get, preparation cost is low；Marc realizes turning waste into wealth, and substantially increases the utilization rate of marc, with
Time be apple pomace resourceization utilize add a new approach；This dietary fiber dry powder contains abundant water soluble dietary fiber,
It is widely used in varieties of food items processing industry, there is Constipation, blood sugar lowering, blood fat reducing and the effect such as anticancer.

The distilled water of 20 times, regulates pH=6.0, adds the protease of defat weight of material 3%, under the Ultrasonic Conditions that temperature is 50 DEG C
Enzymolysis 40min, filters isolated filtrate and filtering residue；Take filtering residue, add the distilled water of filtering residue volume 15 times, regulate pH=5.0,
Add the cellulase of filtering residue weight 8%, enzymolysis 30min under the Ultrasonic Conditions that temperature is 50 DEG C, filter isolated filtrate
And filtering residue；Twice filtrate is merged, obtains enzymolysis solution；By enzymolysis solution steam inactivation 15min under conditions of temperature is 100 DEG C, cold
But to room temperature；Enzymolysis solution after inactivation is placed in Rotary Evaporators, in pressure be 0.08Mpa, under conditions of temperature is 50 DEG C
It is concentrated into the 1/4 of original volume；Calculate with enzymolysis solution volume after concentrating, add 95% ethanol of 4 times of volumes, after mixing, stand 8h, mistake
Filter isolated filtrate and precipitation material, be placed in dehydrator, by precipitation material, ethanol of drying and volatilize, and is subsequently placed in vacuum freezing and does
In dry machine, in temperature for-26 DEG C, vacuum be 40Pa under conditions of lyophilization 10h, obtain described dietary fiber dry powder.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Those skilled in the art should
Understanding, the present invention is not restricted to the described embodiments, and the simply explanation present invention's described in above-described embodiment and description is former
Reason, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes and improvements
Both fall within scope of the claimed invention.Claimed scope is by appending claims and equivalent circle thereof
Fixed.
