Description
Technical field
The present invention relates to a kind ofly freshly to squeeze the juice with pomegranate, pomegranate inspissated juice prepares the method for beverage for raw material, particularly relates to a kind of preparation method of pomegranate juice.
Background technology
Various nutrient is guaranteed to keep in good repair as potassium, calcium, sodium, copper, magnesium, zinc etc. containing abundant carbohydrate, protein, each seed amino acid, vitamin and human body in pomegranate fruit.Wherein sugar content is up to 11%-14%, tartaric acid content 0.4%-1.0%, and ascorbic content is 1-2 times of apple and pears, and it is very outstanding in various fruit that phosphorus content reaches 145mg/kg(), amino acid has tryptophan, phenylalanine, lysine etc.
The medical value of pomegranate fruit is early on the books in Compendium of Material Medica and " dietetic materia medica ": " pomegranate person, sky slurry also, antidiarrheal, stagnation resolvation, clear thirsty, Eradicates is fiery ".
Juice of my pomegranate, except containing except above-mentioned conventional nutrients, also containing abundant polyphenol, anthocyanin isoreactivity material, can be prevented and treated coronary heart disease, hypertension, can reach effect that stomach invigorating is refreshed oneself, whetted the appetite, prolongs life, to the person of drinking beyond one's capacity, have special effect of relieving the effect of alcohol.The polyphenol content of juice of my pomegranate is more much higher than green tea, can play the effect of anti-ageing and anti-knurl for cancer, and not affect most of normal cell.
Present scientific research shows, in juice of my pomegranate containing delaying senility, prevention of arterial is atherosis and slow down the high-efficiency antioxidant agent of canceration process.Containing sterols material in juice of my pomegranate, be a kind of estrogen, effect of the disease such as female climacteric syndrome, osteoporosis is received much concern.
Existing production technology often adopts 85 DEG C of pasteurizes, and sterilizing time is 15min.Because sterilization temperature is low, long sterilizing time, causes pomegranate Middle nutrition material and the intrinsic color and luster of pomegranate to destroy serious, has boiling taste and caramel, affect pomegranate mouthfeel, color and luster in pomegranate.
Summary of the invention
The present invention is directed to deficiency, the preparation method of the pomegranate juice of a kind of mouthfeel and pure color is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A preparation method for pomegranate juice, is characterized in that, comprises following operating procedure:
(1) get the raw materials ready: the fruit juice do not broken a seal is carried the previous day and takes out from freezer, be placed in fruit juice working area, open packaging and weigh, the fruit juice weighed up is pumped into blend tank through 200 order screen packs, and to breaking a seal, unspent fruit juice on duty should be encapsulated into freezer immediately;
(2) allocate: all supplementary material white granulated sugars, food additives are pumped into blend tank after dissolving, the accurate constant volume of output is pressed with blend tank scale, then stir, mixing time is 10-15min, must be up to the standards through product control quantitatively, and provide survey report and to be allowed for access subsequent processing, Interventions Requested comprise pol, acidity, mouthfeel and color, after the assay was approved material are pumped into hold-up tank;
(3) filter: duplex filtration: filter through 100 mesh filter screens after fully dissolving, each use before and after look filter screen breakage and cleaning filter screen;
Cardboard filter
:put into 10 metafiltration paper, open electric lock button, press infusion pump button, now Do not open inlet valve and outlet valve, in time seeing that the water turbidity in form declines, open inlet valve, in time seeing that the fruit juice turbidity in form declines, sample tap is sampled to laboratory and surveys its turbidity, if turbidity is at below 20NTU, then open outlet valve, close circulating valve and return valve simultaneously;
(4) sterilization: sterilization temperature is 96 ± 2 DEG C, the sterilization temperature difference is 2 DEG C, and return valve lag time is 2s, and sterilizing time is 15-20s;
(5) filling: to open cap relief valve, by preheating machine temperature adjusting between 50-70 DEG C, the temperature adjustment of spray-water is between 55-70 DEG C, open electric lock, send water, vapour, vavuum pump adds water, and drives air compressor machine route valve, adjustment output, open air cleaner switch, open main frame, select automatic key, when without material, closing volume key;
(6) fall bottle: by the sterilization of falling bottle chain automatic sterilizing 40-60s;
(7) spraying cooling: adopt two warm area section coolings, first paragraph temperature is 60-65 DEG C, second segment temperature is 55-60 DEG C, finished product temperature is below 35 DEG C, regularly replace temperature lowering water weekly, temperature lowering water requires to add liquor natrii hypochloritis, and concentration requirement is 0.5-1ppm, ensure clean, air-dry, require that bottle surface is without the globule;
(8) finished product pomegranate juice is after spraying cooling.
The invention has the beneficial effects as follows:
Present invention employs UHT(ultra high temperature short time sterilization) technology, sterilization temperature is 96 ± 2 DEG C, and sterilizing time is 15-20s, and can preserve pomegranate color and luster, local flavor and nutriment greatly, therefore mouthfeel and color and luster are all very pure.
