Description

A method of preparing fructus lycii magma fruit juice
Technical field
The present invention relates to fructus lycii processing technique fields, and in particular to a method of prepare fructus lycii magma fruit juice.
Background technique
Polysaccharide rich in, protein, dietary fiber, linoleic acid, carrotene, glucoside, amine in fructus lycii original fruit juice And the special nutrient compositions such as microelement, make it have distinguished edible health effect.But in current fruit juice production work In skill, common fruit juice thermal sterilization technique and general pasteurize all have the shortcomings that its respectively, fruit juice thermal sterilization technique: Rich in the temperature-sensitive factor since sterilization temperature is excessively high and is easy that the denaturation of fructus lycii original fruit juice is made to lead to nutritional ingredient in fructus lycii original fruit juice Loss, the character of product are also unstable;General pasteurize: sterilization temperature is too low, sterilizing time is too long, both destroys fructus lycii Nutritional ingredient in original fruit juice cannot kill the microorganism in fruit juice completely again, to keep product perishable, business is not achieved and protects The requirement of matter phase, it can be seen that common thermal sterilization technique and general pasteurization process are unsuitable for fructus lycii original fruit juice and kill Bacterium.
Fructus lycii original fruit juice is to be squeezed to obtain fructus lycii original fruit juice, the fructus lycii in fructus lycii after carrying out rehydration with dried fruit of lycium barbarum It is extremely difficult to pulverized.Currently used wall-breaking machine, squeezer can not by fructus lycii and crush expressing process in it is broken rotten Fruit skin removes completely completely causes fructus lycii original fruit juice work in-process there are difficulty, and shape of product is unstable after finished product, and reference is got up Taste flavor is not good enough, it can be seen that common broken extrusion process is not suitable for the juicing of fructus lycii original fruit juice.
Summary of the invention
For above-mentioned problems of the prior art, the present invention provides a kind of preparation side of new fructus lycii magma fruit juice Method will directly be sent into screw press and carry out screw press after dried fruit of lycium barbarum rehydration, the wolfberry juice obtained using the technique is complete S.m.p and skin slag, overcome defect in the prior art.
In order to solve the technical problem the technical scheme adopted by the invention is as follows:
A method of preparing fructus lycii magma fruit juice, comprising the following steps:
(1) fructus lycii is handled: take fructus lycii addition pure water and chlorine dioxide effervescent tablet to be impregnated, immersion 5~ 10min is rinsed with clear water;
(2) rehydration: 1~2 times of the pure water that its weight is added in dried fruit of lycium barbarum carries out rehydration, and rehydration time is greater than 10h;
(3) it squeezes: the good fructus lycii of rehydration being subjected to single pressing, collects juice from Chinese wolfberry and expressate respectively;Once pressing Pure water is added in expressate after squeezing and continues twice pressing, collects juice from Chinese wolfberry;
(4) it is centrifuged: single pressing and the resulting juice from Chinese wolfberry of twice pressing being centrifuged, filter out seed excessively, obtains Lycium chinense juice;
(5) it grinds: toward the stabilizer that 0.15~0.25% is added in Lycium chinense juice obtained in step (4), stir 15~ 25min carries out colloid mill grinding;
(6) homogeneous: the Lycium chinense juice after grinding carries out 2 homogeneous in homogenizer, homogenization pressure control 20~ 25MPa;
(7) it sterilizes: the juice from Chinese wolfberry after homogeneous being sterilized 3~5min at 75~85 DEG C, obtains fructus lycii magma fruit juice
(8) filling: the juice from Chinese wolfberry after sterilizing carry out immediately it is filling, filling temperature be not less than 80 DEG C.
Further, in step (1), pure water additional amount is 1.5~2 times of dried fruit of lycium barbarum, and the usage amount of effervescent tablet is 0.15~0.25g effervescent tablet is added in per kilogram fructus lycii.
Further, in step (3), for the squeezer used for screw press, pressing method is screw press.
Further, in step (4), centrifugal rotational speed is 1800~2000r/min, and the time is 3~5min;
Further, in step (4), filtering uses three-stage filtration, and pore size filter is respectively 50 mesh, 100 mesh and 200 mesh.
Further, in step (5), grinding revolving speed is 2700~3000r/min, and flow is 0.3~1t/h.
Further, in step (5), stabilizer needs to be scratched with pure water and white sugar dissolution before being added, wherein 1 part of stabilization 4.5~5.3 parts of white sugar and 48~53 parts of pure water are added in agent.
Further, in step (5), the stabilizer is xanthan gum, carboxymethyl fine plain sodium, calgon, citric acid Sodium, glycerin monostearate and glucose group at compound stabilizer.
Further, in step (5), the stabilizer is xanthan gum, sodium alginate, calgon, sodium citrate, list The compound stabilizer of the composition of tristerin and glucose.
Further, in step (5), the stabilizer is carragheen, sodium carboxymethylcellulose, calgon, lemon Sour sodium, glycerin monostearate and glucose group at compound stabilizer.
Further, in step (5), the stabilizer is carragheen, sodium alginate, calgon, sodium citrate, list Tristerin and glucose group at compound stabilizer.
Further, the fruit juice after filling in the step (8) carries out UHT and sterilizes 4~10s, then at 98~118 DEG C Lower spray sterilizes 10~20min, finally the low temperature instantaneous cooling in 10~15 DEG C of cooling waters.
Compared with prior art, a kind of cordyceps sinensis culture solution provided by the invention, has the effect that
(1) preparation method of the present invention will directly be sent into screw press and carry out screw press after dried fruit of lycium barbarum rehydration, utilize Conventional press method carries out squeezing crushing juice rate between 55%~65% to fructus lycii, and the present invention can make fructus lycii using screw press Crushing juice rate reach 77%~80%, and the juice from Chinese wolfberry that the wolfberry juice that squeezes out of screw press and conventional press squeeze out is opposite Than without residues such as fructus lycii pericarp, fructus lyciis in the wolfberry juice that screw press squeezes out, juice-extracting process shortens, and quality has obtained very Big raising.
(2) wolfberry juice preparation method of the present invention uses 5 step bactericidal assay, tradition of the juice from Chinese wolfberry in the high long sterilizing time of temperature In method for disinfection, the variation of physicochemical property easily occurs, the color of wolfberry juice is dimmed, can generate not pleasant taste and smell Youngster.General cold sterilization is unable to reach the microorganism killed in fruit juice completely again, to keep product perishable, business is not achieved The requirement of shelf-life.So the advantages of five step bactericidal assay, both is being not easy temperature control wolfberry juice is allowed to occur in sterilization process Physical and chemical properties change, the time opposite taste and color for shortening guarantee fructus lycii.Using combination continuous 5 times of instantaneous efficiently suitable temperature Wolfberry juice is sterilized, the coliform group count of the wolfberry juice finally completed is 0, and total plate count is coliform in 34. national standards Number < 0.3, total plate count < 100.Five step bactericidal assay can effectively kill the microorganism in fruit juice, while also assure wolfberry juice Color and taste.
Meanwhile smooth, dimensionally stable product, Chinese wolfberry fruit dry by fructus lycii magma taste of juice exquisiteness that this method is prepared Fruit protoplasm fruit nutritional ingredient will not excessively be lost rich content instead, and amount of dry matter can reach 23%~25%, and solid content reaches 26%~28%.
