Description

Red-core pitaya and carbonated konjak milk tea and preparation method thereof
Technical Field
The invention relates to the technical field of milk tea beverage processing, and particularly relates to red-heart pitaya and konjac carbonate milk tea and a preparation method thereof.
Background
Konjak is a perennial herbaceous plant, and the main component of dry matter in tubers is konjak glucomannan, and in addition, the konjak glucomannan also contains protein, vitamins and mineral substances. Konjac glucomannan is an excellent dietary fiber, and is an ideal low-heat and low-fat substance. At present, the milk tea beverage in the market is less in addition of konjak gel particles.
The dragon fruit is sweet and delicious, is rich in mineral substances such as calcium, phosphorus, iron and the like, and has excellent dietotherapy effect on human health mainly because the dragon fruit contains plant albumin and anthocyanin which are few in common plants. The albumin in the dragon fruit is a stiff and colloidal substance, has the effect of detoxifying heavy metal poisoning, and has a protective effect on the stomach wall. The anthocyanin in red heart pitaya has the effects of resisting oxidation, free radicals and aging, and also has the effects of improving the prevention of brain cell degeneration and inhibiting dementia. Meanwhile, the pitaya also contains vitamins for whitening skin and rich water-soluble dietary fibers for losing weight, reducing blood sugar, moistening intestines and preventing colorectal cancer. The seeds of dragon fruit contain a large amount of unsaturated fatty acid and antioxidant substances, and also have a plurality of health care effects.
People's daily life can not leave food and beverage, and people's requirement to its taste and nutrition is also rising gradually, and food and beverage on the market has can not satisfy people's daily demand, and nutrition is high, and the flavor is good, and the tea drink that the taste is novel more and more receives consumers' favor. Along with the rapid development of the consumption demand of dairy products in China, the subdivision of the dairy product market is more and more obvious, the varieties of the dairy products are more and more day by day, and new products emerge endlessly. Wherein the milk tea beverage is popular and accepted by consumers. At present, the milk tea beverage deeply processed by the dragon fruit is few and few.
The existing milk tea is rarely in the form of carbonated beverage. The carbonic acid gas can promote blood circulation, and calcium, magnesium and trace elements contained in the bubble water can promote blood circulation, thereby helping people recover fatigue and blocking the absorption of saccharides and fat. When the carbonic acid gas is released from the body, a large amount of heat in the body can be taken away, so that the effect of heatstroke prevention and cooling can be well achieved when people drink bubble water in summer.
