Abstract
The invention belongs to food production fields, particularly disclose a kind of processing method of active Chinese yam instant powder.The present invention includes that peeling Chinese yam adds vacuum beating processing after water, disk plate centrifuge that supernatant and sediment, supernatant freeze concentration, freeze-dried preparation activity powder is collected by centrifugation.Water identical in quality is added in centrifugal sediment, is fully gelatinized, and gelatinization Chinese yam starch then is made through roller drying.Activity powder and gelatinization Chinese yam starch are mixed well, to prepare active Chinese yam instant powder.The present invention not only can effectively keep the activity of the effect of Chinese yam ingredient, and can guarantee the instant capacity of each ingredient so that yam flour has both health and instant capacity, and nutrition and conveniently is provided to consumer.
Description
(One)Technical field
The invention belongs to food production field, more particularly to a kind of processing method of active Chinese yam instant powder.
(Two)Background technology
Chinese yam is as a kind of health care food materials, it is reported that as long as China has at least had 2000, the medicinal books of ancient times multi-section are to it
All it is documented.Chinese yam does not have the edible good merchantable brand of simple tonic effect still, and is a kind of common medicinal material, has medicine
Eat dual-purpose value.Chinese yam contains the ingredients such as protein, carbohydrate, vitamin, fat, choline, amylase, also contain I, Ca,
The indispensable inorganic salts of the human bodies such as Fe, P and trace element.Chinese yam nature and flavor are flat, sweet, nontoxic, beneficial to kidney qi, strengthening the bones and muscles, invigorating the spleen
Stomach, resolving sputum saliva, profit fur, controls that let out essence forgetful and other effects at stopping leak dysentery.The nutritional medicinal value and its anti-disease mechanism of Chinese yam are just gradually
Its favor degree is also gradually being improved by extensive concern and confirmation, consumers in general on ground.Modern science is analyzed, rich in Chinese yam
Containing four active component such as mucus albumen, polysaccharide, saponin(e, allantoin, these functional components have anti-oxidant, antitumor, drop blood
Sugar and other effects.
Chinese yam can develop into the multiple products such as yam flour, Chinese yam noodle, yam wine, Yam beverage.Yam flour passes through de-
Water process effectively extends the shelf-life, is also used as dispensing for being a kind of very important Chinese yam in food or drug
Converted products.Patent about yam flour processing at present, such as application No. is 94112473.8 patent " the processing works of Chinese-yam fine flour
Skill ", application No. is 95111876.5 patent " active Chinese yam flour and its manufacturing method ", the patents of application number 95112051.4
" a kind of processing method of active Chinese yam flour ", application No. is a kind of patent of 201210505582.X " freeze and vacuum dried Chinese yams
The production method of powder " is all made of freeze-drying and the method crushed is combined to prepare yam flour, and this method can effectively keep Chinese yam
The activity of middle functional component, but production cost is higher, the starch of Chinese yam does not pass through gelatinization and handles, and leads to product dissolubility
Difference.Application No. is 201510762921.6 patents " a kind of preparation method of yam flour " to dry yam flours using 100 ~ 110 DEG C,
Although production cost can be reduced, the dissolubility of product is improved, in high temperature drying course, the activity damage of Chinese yam functional component
It loses serious.Application No. is the patents of 201610760965.X " a kind of preparation method of iron Chinese yam " to utilize the method for spray drying
Yam flour is prepared, crushing link is reduced, the effective brew for improving product, but the temperature being spray-dried can not ensure mountain
Medicine starch is fully gelatinized, and the purpose of rapid digestion absorption is cannot be satisfied as brewed powder.The existing processing side about Chinese yam powder
Method report is relatively simple, and bioactivity conservation rate is relatively low, lacks and carries out effectively specific aim working process to starch.For Chinese yam
Composition characteristic targetedly studied, exploitation active Chinese yam flour be of great significance for Chinese yam processing and utilization.
(Three)Invention content
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of processing methods of active Chinese yam instant powder.
The present invention is achieved through the following technical solutions:
A kind of processing method of active Chinese yam instant powder, it is characterised in that:Include the following steps:
(1)Chinese yam cleaning, peeling:The straight suitable fresh Chinese yam of smooth, disease-free spot, bar shaped is selected, Chinese yam surface is cleaned in clear water
Dirt is cleaned 2 ~ 3 times, eliminates yam skin by hand;
(2)Segment, mashing:Chinese yam after peeling is cut into 2 ~ 3 centimetres of Chinese yam section, 4 ~ 6 times of water of Chinese yam quality is added, into
Row mashing is handled, and then obtains Chinese yam pulp by vacuum milling treatment of colloid;
(3)Solubilization processing:Chinese yam pulp passes through 2 ~ 4 ultrasonic solubilization processings, to improve the extraction rate of functional component;
(4)Centrifugal treating:Chinese yam pulp through solubilization processing utilizes disk plate centrifuge continuous processing, collects clear liquid and precipitation respectively;
(5)Clear liquid concentrates:Centrifugation gained clear liquid is subjected to freeze concentration processing;
(6)Clear cream powdering:Clear liquid after concentrated is directly freeze-dried, then can obtain Chinese yam activity powder through crushing;
(7)Precipitation gelatinization:Centrifugation gained sedimentation starch is 1 in mass ratio:1 mass ratio adds water to be gelatinized;
(8)Precipitation powder processed:It is 160 ~ 180 DEG C that sedimentation starch through gelatinization, which utilizes bitubular roller drying, drum surface temperature, roller
Rotating speed is controlled at 2 ~ 3 revs/min;Through crushed 80 mesh sieve after roller drying, gelatinization Chinese yam starch is obtained;
(9)Mixing, sterilization:Then Chinese yam activity powder is irradiated with gelatinization Chinese yam starch by batch mixer mixing by 4 ~ 6kGy
Sterilization is to get active Chinese yam instant powder.
Wherein, step(2)In, 3 ‰ ~ 5 ‰ sodium pyrosulfite and citric acid are contained in water, the two mass ratio is 1:1.
Wherein, step(3)In, ultrasonication intensity is 0.2-0.6w/g, and ultrasonic time is 15min/ times;
Wherein, step(4)In, disk plate centrifuge centrifugal rotational speed is controlled at 6000 ~ 8000 revs/min.
Wherein, step(5)In, refrigerant temperature control is at -14 ~ -10 DEG C, and cooling time is 0.6 ~ 1.0 hour, freeze concentration
Series is 3 ~ 5 grades.
Wherein, step(7)In, gelatinization point is 90 ~ 100 DEG C, and gelatinization time is 10 ~ 15 minutes.
The beneficial effects of the invention are as follows:The present invention improves functional component in Chinese yam by ultrasonic solubilization processing repeatedly
Recovery rate, loss of activity of the functional component in concentration process is reduced by multistage freeze concentration technology.According in Chinese yam
The temperature-sensitive sex differernce of starch and functional component, is respectively adopted roller drying and freeze-drying is dried, and can not only keep effect
The activity of ingredient, moreover it is possible to can guarantee the instant capacity of each ingredient.The present invention is dry by ultrasonic solubilising, freeze concentration, freeze-drying, spraying
The technologies such as dry organically combine and are applied in the processing of active Chinese yam flour so that yam flour has both health and instant capacity, to disappearing
Expense person provides nutrition and conveniently.
(Four)Specific implementation mode
Embodiment 1
(1)Chinese yam cleaning, peeling:The straight suitable fresh Chinese yam of smooth, disease-free spot, bar shaped is selected, Chinese yam surface is cleaned in clear water
Dirt is cleaned 2 times, eliminates yam skin by hand;
(2)Segment, mashing:Chinese yam after peeling is cut into 2 centimetres of Chinese yam section, 4 times of water of Chinese yam quality is added, is added
