Description

Date concentrate and preparation method thereof

Technical field

The invention belongs to a kind of drink, relate in particular to a kind of date concentrate and preparation method.

Background technology

Date is described as " kings of all kinds of fruits ", the multivitamin that contains the needed by human such as abundant vitamin A, B family vitamin, vitamin C and 18 seed amino acids, mineral matter.Wherein the competing 70-80 up to grape, apple of ascorbic content doubly, the content of citrin is also very high, these two kinds of vitamins have certain effect to anti-cancer and preventing hypertension, high fat of blood, and date has special nourishing blood and tranquilization, the effect of beauty treatment to female friend.But the bad digestion of date, this be because, date not only moisture is low, only for other Common Fruits of 67%(, mostly be 80% ~ 90%), and dietary fiber content is high, be 1.9%, apparently higher than other Common Fruits (such as grape average out to 0.4%, apple average out to 1.2%), dietary fiber (especially insoluble cellulose) can not be digested in stomach and small intestine, when one time intake is large, can cause upset,gastro-intestinal.Dietary fiber in date mainly concentrates in skin, and the pulp of date is crisp, but fructus corni is very thin and hard, is difficult to thoroughly smash to pieces while chewing.After in daily life date being chewed, do not swallow, spue to observe, can find to be wherein mixed with fructus corni fragment not of uniform size, they are separated with pulp, and shape differs, and quality is hard, sharp edges, can imagine, after swallowing in stomach, if stomach lining just have inflammation or ulcer, be tantamount to salting on wound, can cause pain or discomfort.Certainly, if stomach be healthy, not what inflammation, ulcer or wound, just strong to the tolerance of date so, even so, date overfeeding, also can cause and have a stomach upset.On the other hand, for old man and child due to tooth and spleen and stomach function incomplete, so be more not easy to chew and digest and assimilate.

Summary of the invention

A kind of formula and the preparation method of extracting date concentrate that the object of the invention is to overcome the deficiencies in the prior art and provide.

The present invention is achieved in that a kind of date concentrate, it is characterized in that: comprise the raw material of following parts by weight,

40-60 parts of pure water,

10-20 parts, date.

A kind of preparation method of date concentrate:

Step 1), cleaning: get fresh, complete, without rotten date, be placed on and clean half an hour in pure water more than, till clean;

Step 2), stoning: the date cleaning is placed on to stoning in stoner, and checks stoning rate, guarantee absolutely stoning rate;

Step 3), pulverizing: the date after stoning is heated to 84 ℃ in steam boiler and keeps 10-15 minutes, the date pulverizer after heating is become to jujube paste;

Step 4), enzyme are processed: the jujube paste after pulverizing adds cellulase, and protease, after pectase fully mixes, makes mixture temperature remain on 25--35 ℃ of fermentations 1.5-2 hours;

Step 5), immersion: the date material that enzyme was processed is placed in pure water and soaks, and pure water temperature remains on 30-50 ℃, and soak time is 3-5 hours, do not stop to stir mixture in immersion process;

Step 6), filtration: the date soak of above-mentioned immersion is coexisted in filter and filtered together with diffusate one, obtain date juice;

Step 7), concentrated: date juice is concentrated to 1 hour in vacuum decker, and date juice temperature remains on 30 ℃;

Step 8), sterilization: in sterilizer, high-temperature heating to 84 ℃ keeps carrying out for 5-8 minutes sterilizing;

Step 9), filling: carry out filling with bottle placer.

The available date of one of described raw material or other jujube classes.

Good effect of the present invention is as follows:

1, the present invention has fully preserved the nutritional labeling in date, and through the nutritional labeling enrichment more in concentrated Unit Weight, contrasts by experiment the nutrient composition content of date concentrate of the present invention and existing date juice, is compared as follows:

Comprehensive above table draws: the nutritional labeling in date concentrate of the present invention is effectively protected, and health is highly profitable.

2, in the production process of date concentrate, removed the fructus corni of date, stomach lining has the consumer of inflammation or ulcer, when enjoying date concentrate and bringing benefit, need not worry again that quality is hard, after the fructus corni of sharp edges swallowed in stomach, can not digest, friction, causes pain or discomfort under one's belt.

3, for old man and child due to tooth and the incomplete person of spleen and stomach function, need not chew practical a large amount of dates, just can easily obtain abundant nutrition by date inspissated juice.

The specific embodiment

Embodiment 1: specifically fill a prescription: 100 grams, date, 400 grams of pure water.

Embodiment 2: specifically fill a prescription: 140 grams, date, 450 grams of pure water.

Step 2), stoning: the date cleaning is placed on to stoning in stoner, and checks stoning rate, guarantee absolutely stoning rate;

Step 3), pulverizing: the date after stoning is heated in steam boiler, and temperature controls to 84 ℃ and keeps 15 minutes, and the date after heating is taken out to steam copper, makes date cool to after 26 ℃ under gnotobasis, date is put into pulverizer and become jujube paste;

Step 4), enzyme are processed: the jujube paste after pulverizing adds cellulase, protease, after pectase fully mixes, the consumption of its cellulase is that every 100 grams of dates add 5 grams, the consumption of protease is that every 100 grams of dates add 3 grams, the consumption of pectase is that every 100 grams of dates add 6 grams, and 25-35 ℃ of enzymolysis 1.5-2 hours, in enzymolysis process, jujube paste constantly stirred in reaction vessel;

Step 5), immersion: the date enzymolysis material that enzyme was processed is placed in pure water and soaks, in immersion process, stir date enzymolysis material and pure water mixture 1-2 hours, the date material that makes to ferment is fully dissolved in pure water, then the consumption of 2-3 hours pure water of standing dissolving is 3-5 times of date weight, pure water temperature remains on 30-50 ℃, and soak time is 3-5 hours;

Step 6), filtration: the date soak of above-mentioned immersion is coexisted in filter and filtered together with diffusate one, obtain slubbing leachate, dry after filtering is repeated to step 5, again filter and obtain two road leachates, slubbing leachate Yu Er road leachate is mixed to get to date juice;

Step 7), concentrated: date juice is concentrated to 1 hour in vacuum decker, and date juice temperature remains on 30 ℃, keeps the nutritional labeling of date juice not to be destroyed, and then obtains date concentrate;

Step 8), sterilization: date concentrate is filled into high-temperature heating to 84 ℃ in sterilizer and keeps carrying out for 5-8 minutes sterilizing;

Step 9), filling: carry out filling with bottle placer.
