Abstract
The invention relates to a tea extract and application thereof in grain processing products. The tea extract is prepared by using the following processes: adding 7 to 10 times of drinking water into tea, heating the water at a temperature of between 90 and 100 DEG C, immersing the tea for 5 to 15 minutes, cooling the tea at a temperature of between 30 and 50 DEG C, filtering and concentrating the filter liquor, spraying and drying the filtered liquior into powder to obtain the extract. The tea extract is added into grain processing products such as cakes, bread, cookies, fresh rice flour and fine dried noodles and so on to obviously prolong the guarantee period of the products and solve the problems of easy retrogradation, and so on, and can add color and fragrance of the cakes, the breads and the cookies.
Description
Technical field [0001] The invention relates to a food additive and its application, in particular to a tea extract and its application in food processing products Background technique [0002] Tea contains catechins, tea polyphenols, theanine, trace elements and other functional health ingredients. Pastries, breads, biscuits, fresh wet rice noodles and dried noodles and other food processing products are very important non-staple foods in our daily life. [0003] At present, the main problems in pastry and bread processing are: (1) The shelf life is short (usually only about 3 days) and mold is easy to grow; (2) The starch is easy to regenerate and harden during the shelf life, and the taste becomes rough; (3) Color and luster And the aroma is not good. The main problems in the processing of fresh wet rice noodles are: (1) Short shelf life (only about 1 day), easy to grow mold and bacteria to become rancid; (2) Starch is easy to regenerate and taste worse. The main problem in th...
