Description

Banana, red date composite fruit juice and preparation method

Technical field

The present invention relates to composite natural fruit juice field, be specifically related to banana, red date composite fruit juice and preparation method.

Background technology

Composite fruit juice has important nutritive value, belongs to " alkalescent food ", to safeguarding that health has great significance.Banana quality softness, fresh and sweet fragrance, nutritious, be loved by the people.Every 100 grams of banana carbohydrate containing 18.8 grams, 1.5 grams, protein, vitamin C 10 milligrams, dehydroretinol 00 milligram, potassium 282 milligrams of red dates belong to Rhamnaceae, deciduous tree.Red date is edible both, and also can be used as medicine, Vitamin C content is higher, has tonic effect to human body.Banana belongs to transition type fruit, not easily preserves.For a long time, banana is to eat raw, and processed goods only has a small amount of banana figs, banana sauce, and banana beverage is little, and become beverage with banana flavor Raw material processing merely, its outward appearance, taste are all undesirable.Make beverage with banana and red date with certain proportion compound, be not only of high nutritive value, local flavor is also very unique.This product has certain effect to Constipation, diuresis, has special efficacy to fester hemorrhage, hemorrhoid of gums.In prior art, utilize red date to be combined with other fruit, the composite fruit juice made is more, but coordinates the report making fruit juice still not see with banana.

Summary of the invention

The object of the present invention is to provide a kind of banana, composite fruit juice that red date is made, and the preparation method of this fruit juice, to overcome the deficiencies in the prior art.

Present invention employs such technical scheme:

1), mixing preparation the present invention chooses banana, red date, makes fruit juice respectively, and add auxiliary material, its preparation method is:; 2), homogeneous; 3) degassed; 4) sterilization, cooling.

Be specially: described banana, red date composite fruit juice, be made up, it is characterized in that of bananas juice, jujube juice and auxiliary material, the mass ratio of jujube juice and bananas juice is 10%: 10%.

Described auxiliary material and mass ratio be respectively: white granulated sugar is 14% of gross mass; Compound stabilizer is 0.4% of gross mass.

The preparation method of bananas juice is:

1) choosing fruit: select the banana meeting material quality requirement, reject going rotten grade for failure;

2) remove the peel, cutting: surface clean is clean, removes the peel and be cut into the bulk of 2-3 cm thick after draining table water;

3) mix, pull an oar: mix with the pectase liquid containing 0.5% citric acid, and tentatively pull an oar with 50 order beaters;

4) enzymolysis: pectase consumption 0.03%, hydrolysis temperature 45 DEG C, enzymolysis time 2 hours;

5) pull an oar: the banana liquid after enzymolysis is pulled an oar with 50 order beaters again, and centrifugation also obtains bananas juice.

The preparation method of jujube juice is:

1) choosing fruit: select maturity high, color is purplish red, and pulp is tight, the aromatic strongly fragrant Linze jujube of jujube; Reject the jujube that maturity is low, go rotten, damage by worms, remove the foreign material in raw material;

2) clean: soak with clear water and repeatedly rinse, washing down jujube face foreign material as far as possible;

3) precook: pour red date into jacketed pan and precook, material-water ratio example is 1: 7,75-80 DEG C of boiling 35 minutes;

4) pull an oar: the red date after precooking is reinstated 50 order beaters with liquid one of precooking and pulled an oar, and makes pulp be separated with fruit stone and obtain slurries;

5) filter: by colloid mill furnishing 500-600 order, smash pulp, jujube juice can be obtained after filtration.

The method of described composite fruit juice is following step:

1) proportionally take bananas juice, jujube juice and auxiliary material, mixing preparation, stir;

2) step 1) compound that obtains, be 21 MPas with operating pressure, utilize high pressure homogenizer to enter homogeneous;

3) degassed; Composite fruit juice after homogeneous is degassed through vacuum degassing machine, filling and sealing;

4) sterilization, cooling; The fruit juice of filling and sealing is put into the hot water preheating of 60-80 DEG C, boil after boiling 12-14 minute and be cooled to normal temperature.

Organoleptic indicator of the present invention:

Uniform color is consistent; Mouthfeel is soft, sweet and sour taste, has the fragranced of banana; Fine and smooth, even, nothing precipitation.

Physical and chemical index:

Total pol 10%-13%; Total acidity 0.6%-0.7%; Content of beary metal must not exceed standard.
