Description

The special fruit milk drink of beer

Technical field

The present invention relates to a kind of beverage, particularly relate to the special fruit milk drink of beer.

Background technology

Beer special fruit original name leather bag fruit (locals also claims " bud bread ", acid bar pears, skin tire fruit), that growth is the unique ancient seeds of the one of crown prince's the foot of a mountain, the history of planting of existing more than 1000 year, it is a local cultivar of rose family Maloideae Xinjiang pears system, be in the upper limit of Pyrus L distribution, have that tree vigo(u)r is strong, the age of tree is long, tight to soil requirement, like the features such as dark and damp cold-resistant, disease and insect resistance, strong adaptability.

Beer special fruit sweet and sour, warm in nature, containing rich in protein, reduced sugar, crude fibre, vitamin (C, B ₁, B ₂), tannic acid, amino acid and potassium, calcium, the multiple needed by human such as iron mineral matter element, be moistening lung nourishing the stomach among the people, disappear rush down quench the thirst, the dietotherapy good merchantable brand of softening blood vessel, Antialcoholic liver-protecting.Its fruit has high heat energy (1.78kcal/g), and is rich in multiple nutritional components: protein content is 0.2% ~ 1.0%, Cobastab ₂1.5 μ g/g, crude fat 0.43%, crude fibre 2.94%, Fe 39 μ g/g, total reducing sugar (glucose) 8.0%, total acid (malic acid) 0.6%, higher than other pears class; Amino acid in fruit is ɑ-amino acid, rich content, nearly 20 kinds, and wherein the methionine of needed by human, phenylalanine are higher than Kiwi berry, and tryptophane 0.15 μ g/g is high compared with other fruit.

The special fruit of beer on average moisture 88.0%, irreducible water is constantly converted into Free water by fruit in storage, causes fruit deliquescing, and this is the special fruit of beer is difficult to a preservation major reason than general fruit.The special fruit of beer probably needs about 15 ~ 30 days from after harvesting to the after-ripening of beer special fruit, sugar content is by being slowly increased to quick increase, when finally arriving maturation, its sugar content tends towards stability gradually, its after-ripening and holding conditions have substantial connection, reasonable adjusting holding conditions, is conducive to increasing the flavor substance in After-ripening.Tart flavour is the important component affecting taste of fruit, and fruit is because having tart flavour containing various organic acid.Organic acid contained in fruit mainly contains malic acid and citric acid.The acid content of fruit not only affects local flavor and quality, also produces important function to the activity of microorganism.Fruit is many containing acid, can increase the heat sensitivity of microorganism, reduce the resistivity to high temperature.The special fruit of beer is in storage, and acid content reduces gradually, and this is also another reason that it is difficult to preserve.

At present, beer special fruit processing main path is beer special fruit fruit juice, and research mainly concentrates on the special fruit juice formula of beer, the beer special fruit aspect such as polysaccharide and nutritional labeling thereof.Such as, the people such as Yang Xuxing, Ma Shuwen by research Normal juice with sweet generation sugar ratio to obtain the formula of the special fruit drink of beer as follows: beer spy fruit juice 30%, white granulated sugar 5%, honey element 0.1%, caramel colorant 0.8%, honey 0.8%, citric acid 0.12%.Qi Yong, Luo Yan are with the special fruit of beer for raw material has carried out juice beverage prescription research, and the optimum formula of the special fruit juice of determined beer is: beer special fruit juice 30%, white granulated sugar 6%, mountain flower honey 0.8%, caramel colorant 0.10%, citric acid 0.06%.

But based on common allotment type fruit drink, the special fruit product of beer is single, and the Consumer groups met is limited.

Along with growth in the living standard, trophism, local flavor and security have become the most basic demand of people to beverage.Milk-containing low-pH fruit juice beverage comes into the market as a kind of novel sapor beverage, and it is with unique flavor, light taste, and color and luster is pleasant, and nutritious feature is subject to the favor of people.Fruit is the main source of body vitamin and mineral matter, and fruit cellulose can stimulate intestines peristalsis, helps digest, promotes that refuse is got rid of, prevention alimentary tract cancer.Cow's milk contains rich in protein and calcareous, is added by fruit in cow's milk and produces fruit dairy products, the nutrition of the nutrition of cow's milk and fruit and health care effectively can be combined, combine together.Therefore, the market value also increasing fruit juice while the special fruit milk drink of beer improves the nutrition of fruit juice own is developed.

Summary of the invention
