Kuerle delicious pear is of high nutritive value; containing the abundant composition such as vitamin, glucose, amino acid, tannic acid, pectin, various trace elements in fruit, have promote the production of body fluid to quench thirst, clearing heat and eliminating phlegm, relax bowel, reduce blood pressure, cardioprotection, lessen fatigue, strengthen myocardial viability, improve have a dizzy spell, cancer-resisting, the multiple nutrients effect such as to relieve the effect of alcohol.
This patent take Kuerle delicious pear as raw material, obtained active bergamot pear juice after pretreatment of raw material, the blunt enzyme of microwave, tissue mashing, two enzyme enzymolysis, centrifugal filtration, radio frequency sterilization, sterile filling.The oxidase active by microwave treatment passivation, effectively improves the crushing juice rate of bergamot pear, inhibits the enzymatic oxidative browning of bergamot pear juice through biological enzymolysis.The radio-frequency apparatus of intrinsic frequency is adopted to carry out sterilization to bergamot pear juice, shorten sterilizing time, energy-saving and cost-reducing, improve bergamot pear juice color and luster, local flavor and nutritional activities function thereof, preparation bergamot pear juice meet consumer to fruit juice nutrient, natural, health care demand, there is wide market development potential.
Three, summary of the invention
Technical problem the present invention is low mainly for crushing juice rate in Kuerle delicious pear deep processing, enzymatic browning, the nutritional activities loss problem such as large, adopt biological enzymolysis, radio frequency sterilization technology, develop bergamot pear juice that is bright in colour, nutritious, peculiar flavour, meet people to local flavor, nutrition, healthy demand.
Technical scheme the invention provides the preparation method of the active bergamot pear juice in a kind of Kuerle, and particular content is as follows:
A, raw material select, pretreatment: pluck, select fresh full, meat is fine and close, maturity is high, without disease and pest and rotten high-quality bergamot pear, bulk is cut into after cleaning, impurity such as removal carpopodium, fruit stone etc., after the saline solution putting into 0.5-5% soaks 1-10min, wash down pulp surface raffinate by deionized water;
The blunt enzyme of B, microwave: Pear-fruit cube meat is put into conveyor type tunnel microwave device and carry out heating 10-200s, conveyer belt rotating speed is: 300-1500rpm, and microwave power is: 300-1500W;
C, tissue mashing: the fruit pulp after blunt enzyme puts into tissue mashing machine, pull an oar 2-10min under 400-1000rpm condition;
D, two enzyme enzymolysis: in bergamot pear slurry, add cellulase and pectase carries out enzymolysis, add the 0.04-0.08% that cellulase quality accounts for bergamot pear slurry quality, pectase quality accounts for the 0.04-0.08% of bergamot pear slurry quality, controlled enzymatic hydrolysis temperature 40-60 DEG C, pH4.0-5.5, mixing speed 500-1000rpm, enzymolysis 30-100min;
E, centrifugal filtration: starched by enzymolysis bergamot pear and carry out centrifugal filtration under 3000-4000rpm condition, obtain the bergamot pear juice clarified;
F, radio frequency sterilization, sterile filling: bergamot pear juice puts into radio-frequency apparatus, fixed frequency is 27.12MHz, and the radio frequency time of employing is 140-200s, and electrode thickness is 105-115mm, and fruit juice thickness is 25-45mm, carries out radio frequency sterilization, then sterile filling.
Major advantage of the present invention and good effect as follows:
1, by the blunt enzyme of microwave and two enzymes method biological enzymolysis, effectively inhibit enzymatic browning, significantly improve the crushing juice rate of bergamot pear, promote the stripping of nutrient substance, improve nutrition and the active function of product.
2, adopt radio frequency sterilization bergamot pear juice, ensure that the color and luster of bergamot pear juice, local flavor and neutraceutical active ingredients to greatest extent, meet the demand of consumer to fruit juice nutrient, natural, health care, there is wide market development potential.
