Summary of the invention:
The objective of the invention is to reclaim lemon juice for biologically active nutritional labeling in a kind of lemon pomace that can make full use of after squeezing the juice is provided, the employing zymolysis technique that improves lemon fruit crushing juice rate to greatest extent extracts the method for lemon juice from the lemon pomace.
The objective of the invention is to realize like this:
The present invention adopts zymolysis technique from the lemon pomace, to extract the method for lemon juice, may further comprise the steps:
1) selecting for use of lemon pomace: select for use the lemon fresh fruit to carry skin oil, fruit juice through juice extractor; And to the lemon pomace that contains pericarp, capsule clothing, pulp grain etc. after fruit oil, juice, seed, the slag separation; The lemon pomace is rich in the pectin, cellulose, hemicellulose, protein, group vitamins, starch, fructose, tartaric acid, fragrance of lemon fruit characteristic etc. to human body beneficial, effective composition; Handle the back, obtain lemon juice through this biological enzymolysis technology, make it to obtain more fully, reasonably recovery;
2) enzyme that goes out of heating: through 80 ℃ of-90 ℃ of temperature controls, 3min-4min enzyme that goes out is cooled to rapidly≤55 ℃, and purifying, softening skin slag are avoided product brown stain in the process of back;
3) fragmentation: the lemon pomace of bulk is broken into the skin slag particle of particle diameter≤3mm after squeezing the juice, for add water, making beating creates conditions, and is beneficial to enzyme preparation large tracts of land effect equably;
4) making beating: the skin slag particle after the enzyme that goes out, fragmentation; Temperature control to 20 ℃-60 ℃; Through measuring active ingredient pectin, cellulose, protein component content in the skin slag particle, allocating enzyme preparation into and break into the skin dreg slurry through beater; The large tracts of land effect equably of lasting enzyme preparation is decomposed iuntercellular strand and breaking-wall cell vigor in order to enzyme preparation in back operation performance maximum enzyme;
5) enzymolysis: the skin dreg slurry is sent into the 15 commentaries on classics/min-45 commentaries on classics/min enzymatic vessel after sterilization through pump line; 20 ℃-60 ℃ of temperature controls carry out comprehensive enzymatic liquefaction, and pectin, cellulose, hemicellulose, starch, protein are negative to be terminal point to detecting; Time 1h-2h gives full play to the decomposition liquefaction of enzyme preparation to fruit grain strand, breaking-wall cell in the pomace slurry;
6), filter: the lemon pomace slurry (liquid) that behind enzymolysis, obtains through centrifuge separation, filtration, obtains the lemon juice that reclaims again; Realize that fruit juice syrup, slag separate, and ensure Bu dissolubility Gu Xing Wu in the fruit juice ≦ 3%;
7), can: according to the market demand, through sterilization, be filled into the sterile bag of overcoat metal bucket or carton, go into the storage of low temperature storehouse, this recovery lemon juice directly is used as the allotment fruit drink after sterilizing, or through the aseptic filler can, goes into the low temperature storehouse and store.As food, Beverage Service agent raw material.Owing to have lemon fruit composition characteristic.Edible safety.
Above-mentioned enzyme preparation is at least a in pectase, cellulase, hemicellulase, amylase, the protease, by weight: skin slag: pectase: cellulase: hemicellulase: amylase: protease=1: 0.1 ‰-0.3 ‰: 0.1 ‰-0.4 ‰: 0.1 ‰-0.4 ‰: 0.1 ‰-0.2 ‰: 0.1 ‰-0.3 ‰.
Above-mentioned step 1,6) after lemon juice is carried out vacuum evaporation and concentrate, form and concentrate lemon juice.Can be according to market demands, return aquatic foods squeeze the juice in, advance vacuum evaporation and concentrate the pol of must breasting the tape: 40 ° of Brix-65 ° of Brix concentrated lemon juice products.
The present invention adopt zymolysis technique improve the lemon crushing juice rate have good component molecules such as pectin, cellulose, hemicellulose, starch, protein, fragrance in the dissolving lemon pomace, breaking-wall cell with strong points, have and can avoid dissolving characteristics and effect bitter in the lemon, smelly bad flavor again.
The present invention is in the residue pomace after extracting skin oil, squeezing the juice, separate with multiple biological enzyme formulation integrated use; Pass through enzyme solution; Specific aim is carried out the biologically active nutrition in breaking-wall cell, the liquefaction lemon pomace, reclaims and also is stored in the lemon juice in the lemon pomace after juice extractor is squeezed the juice, and this method can promote its product fragrance, flavor quality to greatest extent; Improve lemon fruit crushing juice rate more than 8%-20%; Isolated tailings has promoted lemon processing added value greatly because the reduction greatly of thickness composition can be carried out granulation, dry dietary cellulosic and the feed product produced more easily.
The inventive method is applicable to other kind fruit juice processing of sweet tangerine class.
The specific embodiment:
The present invention adopts zymolysis technique from the lemon pomace, to extract the method for lemon juice, may further comprise the steps:
1) the lemon pomace selects for use; Select for use the lemon fresh fruit through carrying skin oil, fruit juice, and to the lemon pomace of the pericarp after fruit oil, juice, seed, the slag separation, capsule clothing, pulp grain;
2) heat and go out enzyme through 80 ℃ of-90 ℃ of temperature controls, 3min-4min enzyme that goes out is cooled to rapidly≤55 ℃;
3) fragmentation: crusher in crushing becomes the skin slag particle of particle diameter≤3mm;
4) making beating: the skin slag particle after the enzyme that goes out, fragmentation, temperature control to 30 ℃-54 ℃ is measured active ingredient pectin, cellulose, protein content in the slag, is allocated enzyme preparation-pectase, cellulase etc. into and break into the skin dreg slurry through beater; By weight: skin dreg slurry: pectase: cellulase=1: 0.2 ‰: 0.3 ‰;
5) enzymolysis: the skin dreg slurry is sent into the 15 commentariess on classics/min-45 commentariess on classics/min enzymatic vessel after sterilization through pump line, and it is terminal point to detecting pectin, cellulose, hemicellulose, starch, protein feminine gender that 30 ℃-54 ℃ of temperature controls carry out comprehensive enzymatic liquefaction, time 1h-2h;
6) filter: the lemon pomace slurry (liquid) that behind enzymolysis, obtains, separate, filter through centrifuge again, obtain the lemon juice that reclaims;
7) can: according to the market demand, through sterilization, can, be filled into the sterile bag of overcoat metal bucket or carton, go into the storage of low temperature storehouse.
Also can after step 6), the lemon juice that reclaims be carried out vacuum evaporation and concentrate, obtain concentrating lemon juice, and then carry out can.
The foregoing description is that foregoing of the present invention is further described, but should this scope that is interpreted as the above-mentioned theme of the present invention only not limited to the foregoing description.All technology that realizes based on foregoing all belong to scope of the present invention.
