3. a kind of Chinese yam longan health-care Yoghourt health drink according to claim 1 and preparation method thereof, which is characterized in that The 40MPa homogenization in high pressure homogenizer by the raw material being beaten in the step b is filtered with 80 mesh filter screens.
Technical field
The present invention relates to a kind of preparation methods of Chinese yam longan health-care Yoghourt, belong to food processing technology field.
Background technique
Chinese yam is the stem tuber of Dioscoreaceae plant Chinese yam, is a kind of traditional medicinal and edible plant full of nutrition.Contain in Chinese yam There are starch abundant, protein, saponin(e, lymphatic temperament, glycoprotein, mannosan, phytic acid, allantoin, batatasins, choline, DOPA The Multiple components such as amine, crude fibre, pectin, amylase and various trace elements have enhancing body's immunity, adjustment intestines Stomach, hypoglycemic, anti-aging, lipid-loweringing, antitumor, anti-oxidant and other effects.
Longan contain protein, fat, 16.2% carbohydrate and V abundantC, thiamine, riboflavin, niacin and calcium, Phosphorus, iron etc., also containing substances such as tartaric acid, adenine, choline.Longan is warm-natured, it is sweet in flavor, there is Appetizing spleen-tonifying, is nourishing blood and tranquilization, strong The effect of positive QI invigorating, qi-restoratives intelligence development.Chinese yam and longan are a kind of traditional medicinal and edible plants full of nutrition.Yoghourt can be tieed up The intestinal flora ecological balance is held, inhibits pathogenic bacteria and anti-infective, reduction blood middle cholesterol content, improve constipation, pre- anti-aging, drop Lower lactose level alleviates lactose intolerance, improves absorption of the human body to calcium ferrophosphorus.
Summary of the invention
A kind of it is an object of that present invention to provide preparation processes Chinese yam longan health-care Yoghourt simple, full of nutrition.
A kind of Chinese yam longan health-care Yoghourt and preparation method thereof, it is characterised in that raw material is mixed by following parts by weight:
50-60 parts of fresh milk
30-40 parts of Chinese yam pulp
3-4 parts of longan juice
6-7 parts of sucrose
3-4 parts of lactic acid bacteria
Processing technology is as follows:
A. the preparation of Chinese yam pulp: mature, the mildew and rot Chinese yam of nothing is selected, is impregnated and is washed away the impurity such as surface silt, cut after peeling It at 4mm~5mm thickness piece, and is immediately placed in prepared colour protecting liquid, in the ratio of Chinese yam and water 1: 4, in high-speed organization Chinese yam pulp is broken into bruisher, after 90 DEG C~95 DEG C gelatinization 30min, filters and Chinese yam pulp is made.
B. the preparation of longan juice: high-quality longan (no to go mouldy, without insect population) is selected, decladding, stoning are washed in a pan dried longan pulp with clear water Wash clean removes chalk dust removing, impurity.30min is boiled at 90 DEG C again after adding 5 times of boiling boilings.Dried longan pulp is sent into together with infusion water and is beaten It is beaten in pulp grinder.The homogenization in high pressure homogenizer by the raw material being beaten removes filter residue with strainer filtering, and filtrate is placed in 4 It is spare in DEG C refrigerator.
C. allotment, homogeneous, sterilization, cooling: milk, Chinese yam pulp, longan juice, sucrose are deployed according to design proportion, 0.3% stabilizer is added to be uniformly mixed.After 25MPa homogeneous 2 times, then 95 DEG C of heating water bath 5min are cooled to 42 DEG C.
D. inoculation, canned, fermentation: strain is accessed in mixture according to design proportion, is poured into container after stirring evenly, 42 DEG C fermentation.
E. after-ripening: the cream fermented is placed in 2 DEG C~7 DEG C or so of refrigerator and refrigerates 12h progress after-ripening.
Colour protecting liquid described in step a is 0.15%CA and 0.05%VCMixed liquor.
40MPa homogenization in magma high pressure homogenizer described in step b, then filtered with 80 mesh filter screens.
