Background technology
Milk tea is the invention that nomadic people and the Nature perfect adaptation are created, and as its name suggests, is exactly milk and the combining of tea, and has strong fragrance and special taste.Milk tea is claimed " Su Taiqie (Su Taicai) " in Mongol, be the food that herdsman must drink every day, and they often say: " would rather no meal on the one, also can not no tea on the one ".The preparation method of tradition milk tea is: the brick tea water is decocted, when millet paste is dense, add a little salt and mix with milk, just processed after opening with pan boiling.This method limitation of having tea is very big, and the one, drinking milk's tea time must possess tea, milk, salt etc., and the 2nd, infusion is more bothersome; The 3rd, milk tea is a kind of liquid beverage, and both inconvenience was preserved, and was also not portable; The 4th, sanitary condition is not ideal, and quality also is not easy control.
To drink milk tea convenient in order to make, and canned and bottled milk tea beverage and solid milk tea powder arise at the historic moment.Canned and bottled milk tea beverage and solid milk tea powder are main with sweet taste mainly at present, not too are fit to the custom and the food feature of national taste.Even more serious is that some milk tea fall short of the reality, and that is to say and seldom contains milk or milk powder, does not even contain the composition of milk, is to process with vegetable fat powder (claiming cream again) and white sand Icing Sugar mixing preparation mostly, is unfavorable for consumer's health.According to investigations, functional milk tea powder with health role is the blank of current food products market, especially the demand of society.
Along with The development in society and economy, the milk tea powder makes the national tradition cooking culture to the infiltration of modernization civilization, and the demand of milk tea powder is with increasing, and no longer just herdsman's proprietary food has formed the food and drink that various nationalities enjoy jointly.Various milk tea in the market are a kind of common milk-contained drink, and itself does not have health-care efficacy.Because the variation and the physiological change of eating habit, like rich food such as gluttonous mutton, dog meats and spicy food etc., some eat milk tea after a period of time, the symptom of getting angry can occur.Like phenomenons such as lip drying, canker sore, constipations.National patent CN101664065A discloses a kind of " inflammation-relieving health-care milk tea and preparation method thereof "; Be formulated by having the dispel cold tea (Chinese herbal medicine) and the cow's milk of fiery effect of heat-clearing; Do not contain tea component, do not tackle the problem at its root, also can have a strong impact on the local flavor of milk; The characteristic that does not more have traditional milk tea, nor it is edible to be fit to the north cold area herdsman.Investigation finds that also there are the problem that much is unfavorable for health in herdsman's area diet structure and dietary behavior, mainly contain following aspect: high-energy food intakes such as (1) poultry meat and animal tallow are too much; (2) fresh vegetables and fruit intake are few; (3) edible salt intake is higher; (4) long-term heavy drinking, and be high spirit, it is higher with the amount of drinking to drink number of times every day.So the incidence of disease of hypertension, high fat of blood, diabetes, obesity is very high, how to reduce this healthy important risk factor, need work from dietetic nutrition science aspect more.Functional health-care food is to utilize the traditional medicine food dual purpose plant of China to develop mostly at present; And the form with non-traditional food such as tablet, capsule, oral liquid, electuaries occurs mostly; Give a kind of sick pressure of taking medicine of people; The eating habit that can not adapt to people is difficult to satisfy consumers in general's demand.Therefore, the exploitation of functional milk tea powder has crucial meaning to keeping fit.
