Problems solved by technology

However, this technology will result in insufficient jujube cell crushing, low extraction rate, deep color of the extract, cooked and scalded taste, serious loss of heat-sensitive substances (such as vitamin C) and other consequences.
[0005] Hetian jujube has a high colloid content, so only the extraction process can be used, and the filtration is difficult due to the high viscosity during solid-liquid separation
In the prior art, th

Abstract

The present invention relates to a clarified Hetian date beverage and a production method thereof. The production method includes the following steps: preparing jujube pulp, conducting enzymolysis on the jujube pulp, collecting enzymatic hydrolysis liquid, rotational flow washing, membrane separating, blending, sterilizing, canning, etc. The Hetian jujubes are used as raw materials, and jujube juice is extracted through dry grinding and enzymolysis process under a low temperature condition to ensure that products are good in color and luster and flavor, and nutrient substances are effectively retained. The extraction rate, preservation rate and light transmittance of the obtained jujube juice are more than 75%, 85% and 75%, respectively. The mouthfeel, color and flavor consistent clarified jujube juice beverage and jujube paste are obtained through the blending process, realizing the deep processing of the Hetian jujubes, and increasing the added value of the products.

Description

【Technical field】 [0001] The invention relates to the field of food technology. More specifically, the present invention relates to a Hetian jujube clarified beverage, and also relates to a production method of the Hetian jujube clarified beverage. 【Background technique】 [0002] Red jujube (Zizyphus Jujuba jujube) zizyphus jujuba dates is the fruit of the genus Jujuba in Rhamnaceae, also known as Chinese jujube, jujube, dried jujube, etc. There are many varieties of red jujube in my country. variety, is a specialty fruit in my country. my country is rich in jujube resources, with an annual output of more than 4 million tons, accounting for more than 95% of the world's jujube production. It is the only country in the world that exports jujubes. Jujube has extremely high nutritional and health functions. It has the functions of invigorating deficiency and Qi, nourishing blood and calming the nerves, strengthening the spleen and stomach, and is a natural food with the same so...
