Background
The tea industry refers to the industry of providing consumers with beverages of various tastes and types based on tea through innovation and improvement. The main products in the industry comprise traditional tea such as green tea, black tea, oolong tea, white tea, yellow tea, black tea and the like, and novel tea such as milk tea, fruit tea, scented tea, cold tea and the like. The development of the modern tea industry benefits from consumer pursuits for healthy lifestyles. The tea contains abundant antioxidant substances, and can help consumers resist free radical attack and delay aging. In addition, the tea is helpful for digestion, blood pressure reduction, blood lipid reduction, etc. As a result, more and more consumers are beginning to choose tea beverages as a daily drink. In order to meet the pursuit of consumers for taste and nutrition, tea brands are continually pushed out new products and small materials with rich varieties, and diversified choices are provided for consumers. The popular trend of the tea beverage with the materials promotes merchants to push out colorful taro balls, square roast mesona chinensis, spherical tortoise jelly, crisp waves, fleshy, cold days, konjac, rice sweet potatoes, red glutinous rice, nut pieces, oreodonia biscuit pieces and the like besides the conventional pearls, coconuts and red beans. The red glutinous rice is selected as a popular small material, has thick glutinous aroma and rich taste, and the related five-cereal tea drink added with the red glutinous rice is deeply touted by consumers. The Oryza Glutinosa is rich in proteins, amino acids, microelements, anthocyanin, etc., and has anticancer, antiallergic, obesity preventing, arteriosclerosis preventing, cardiovascular disease preventing, etc. Before the red glutinous rice is added into tea, the red glutinous rice is required to be cleaned and soaked for more than two hours in advance for soaking, then the red glutinous rice is poured into a pot, water is added into the pot for boiling into porridge, and a proper amount of sugar, honey, light milk or condensed milk is added for increasing sweetness and taste.
At present, the application of the traditional red glutinous rice small-size tea beverage has two major problems, namely, the high content of the surface fiber of the red glutinous rice and the fine texture, long cooking time and unstable cooking quality, and the hard taste of the whole red glutinous rice, and poor eating feeling in tea beverage application. In view of the above, a better solution is needed for batch processing of small red glutinous rice samples.
