Description

A kind of Japanese Premna pectin agar and preparation method thereof
Technical field
The invention belongs to food processing technology fields, and in particular to a kind of Japanese Premna pectin agar and preparation method thereof.
Technical background
Japanese Premna is a kind of perennial machaka of horsewhip section Premna, and dietary fiber content is rich in premna microphylla Richness is especially enriched in pectin, and Japanese Premna fresh leaf is squeezed the juice and is filtered, and filtrate is added plant ash clarified solution and stands after mixing evenly, due to Gelatification is generated between bivalent metal ion in low-ester pectin in Japanese Premna leaf juice and plant ash clarified solution, forms jelly The Japanese Premna pectin jelly of shape, is commonly called as kwan-yin bean curd.Japanese Premna pectin jelly green in color, satiny flexible, it is sunstroke prevention that fragrance is refrigerant The good merchantable brand of cooling, often edible Japanese Premna pectin jelly can also play the beneficial effect of relax bowel and defecation and liver-nourishing and eyesight-improving.Japanese Premna is Machaka, leaf picking phase are annual May to October, and other times are the leaf fall period, and fresh leaf is not easy to protect for a long time It deposits, causes fresh leaf supply to be limited by seasonality, the supply shortage phase of nursery stock leaf fall period and Japanese Premna pectin jelly product.
In order to solve the problems, such as that the supply of Japanese Premna fresh leaf is limited by seasonality, guarantee that Japanese Premna pectin jelly product is annual There is supply, the present invention is directed to develop a kind of Japanese Premna pectin agar, with the pectin jelly of Japanese Premna pectin agar preparation and with beans The pectin jelly of rotten bavin fresh leaf preparation in terms of the quality index such as texture and sense organ without significant difference, and Japanese Premna pectin jelly Powder raw material be it is dry powdered, can be stored, be solved since Japanese Premna fresh leaf is not easy long term storage, in bean curd with the long period The production of bavin nursery stock leaf fall period pectin jelly is limited the problem of running out of goods by fresh leaf.
Summary of the invention
The present invention is by four kinds of premna microphylla dry powder, premna microphylla low-ester pectin powder, calcium carbonate and citric acid raw materials according to one Certainty ratio is uniformly mixed obtained Japanese Premna pectin agar, and Japanese Premna pectin agar is added appropriate warm water, stands after mixing evenly, coagulates Solid is at Japanese Premna pectin jelly, with the pectin jelly of Japanese Premna pectin agar preparation and with the pectin jelly of Japanese Premna fresh leaf preparation in matter There is no significant difference in terms of the quality index such as structure and sense organ.
Premna microphylla dry powder is squeezed the juice with Japanese Premna fresh leaf, and filtered filtrate is spray-dried to be made, the low ester fruit of premna microphylla Rubber powder is extracted from Japanese Premna fresh leaf to be made, and directly from market, purchase is obtained for calcium carbonate and citric acid, and four kinds of raw materials are drying It is powdered, it can be stored, be solved since Japanese Premna fresh leaf is not easy long term storage, in Japanese Premna nursery stock leaf fall period fruit with the long period Jelly production is limited the problem of running out of goods by fresh leaf.
A kind of Japanese Premna pectin agar and preparation method thereof specific steps are as follows:
(1) preparation of premna microphylla dry powder.The Japanese Premna fresh leaf for winning no disease and pests harm, cleans up, and is placed in 5~10 times of matter In the deionized water of amount, 3~10min is beaten under the conditions of 20~30 DEG C, 1000~3000r/min of revolving speed, juice is through 60~80 Mesh filtered through gauze takes filtrate, and premna microphylla dry powder is made in spray drying.
(2) preparation of premna microphylla low-ester pectin powder.The Japanese Premna fresh leaf for winning no disease and pests harm, cleans up, drying, powder The broken powder for 60~80 meshes can be crossed;Powder is placed in the deionized water of 10~50 times of quality, with citric acid regulation system PH is 2.0~4.0, and 2~5h, centrifuging and taking supernatant are extracted in stirring under the conditions of 40 DEG C~70 DEG C, 100~150r/min of revolving speed; Supernatant is concentrated into the 20%~30% of original volume, the dehydrated alcohol of 3~8 times of volumes is added, 2~3h is stood after mixing, from The heart takes precipitating;Centrifugation is placed in the deionized water of 50~100 times of quality, stirring is added 5%~10% to being completely dissolved The ammonium acetate solution of volume fraction stirs 12~36h of de-ester reaction under the conditions of 30 DEG C~50 DEG C, 100~150r/min of revolving speed Afterwards, the pH for adjusting reaction solution is 1.0~3.0, and the dehydrated alcohol of 1~3 times of volume is added, 2~3h, centrifuging and taking are stood after mixing Precipitating;Centrifugation is added water to and is completely dissolved, after dialysis desalting, premna microphylla low-ester pectin powder is made in spray drying.
(3) preparation of Japanese Premna pectin agar.According to mass fraction, premna microphylla dry powder 70%~90%, premna microphylla Low-ester pectin powder 10%~30%, calcium carbonate 0.01%~0.1%, citric acid 0.01%~0.1%, sealing are uniformly mixed, system Obtain Japanese Premna pectin agar.
(4) premna microphylla dry powder drying condition described in step (1) are as follows: 150 DEG C~180 DEG C of inlet air temperature, out 70 DEG C~90 DEG C of air temperature, 5~10mL/min of flow velocity.
(5) acetic acid ammonium concentration is 20~30g/L in ammonium acetate solution described in step (2).
(6) premna microphylla low-ester pectin powder spray drying condition described in step (2) are as follows: inlet air temperature 180 DEG C~200 DEG C, 60 DEG C~80 DEG C of leaving air temp, 10~20mL/min of flow velocity.
(7) warm water that the temperature of 80~120 times of quality is 30~60 DEG C is added in Japanese Premna pectin agar, stirred evenly, 5~25min is stood, solidification forms Japanese Premna pectin jelly.
Advantageous effects of the invention are embodied in the following aspects:
(1) four kinds of premna microphylla dry powder, premna microphylla low-ester pectin powder, calcium carbonate and citric acid raw materials are dried powder Shape, moisture content is low, can be stored with the long period, solves since Japanese Premna fresh leaf is not easy long-term preservation, in Japanese Premna nursery stock Leaf fall period Japanese Premna pectin jelly production is limited the problem of running out of goods by fresh leaf.
(2) by designing Japanese Premna pectin agar formula, using premna microphylla dry powder as primary raw material, the low ester of premna microphylla Jelly powder is auxiliary material, and slightly solubility calcium salt calcium carbonate is gelling agent, and citric acid is acidity regulator.In Japanese Premna pectin agar It adds water and stirs to be formed during pectin jelly, premna microphylla low-ester pectin powder dissolves and generates gelatification with calcium ion first, increases Big solution viscosity, reduce solution mobility, then the low-ester pectin in premna microphylla dry powder gradually dissolves out, and in slant acidity item The calcium binding discharged in situ under part forms gel, and premna microphylla dry powder and premna microphylla low-ester pectin powder are used in mixed way, no The pectin jelly compact structure that the pectin jelly coagulation forming time can only be shortened, and formed, high resilience, with Japanese Premna pectin jelly Powder preparation pectin jelly and with Japanese Premna fresh leaf preparation pectin jelly in terms of the quality index such as texture and sense organ without conspicuousness Difference.
(3) form of Japanese Premna pectin agar is powdered, light-weight, can be substantially compared with Japanese Premna pectin jelly finished product Degree reduces transportation cost.
