Xi Anfuide Food & Beverage Co., Ltd. was established in 1960, which is a large-scale food and beverage production enterprise in northwest China. The company covers an area of 50 mu and has a modern production workshop with advanced equipment and strong technical force. Fruit juice beverage is a fruit juice or mixed fruit juice product made from fresh or frozen fruits with moderate maturity, or a product made by adding sugar liquid, sour agent and other ingredients. The finished product can be drunk directly or diluted. This kind of beverage is also divided into raw juice, fresh juice, concentrated juice and juice syrup. Fruit juice beverage is an ideal beverage with rich nutrition and easy digestion, and because it is rich in organic acids, it can stimulate gastrointestinal secretion and help digestion, and also make the upper part of the small intestine acidic, which is helpful for the absorption of calcium and phosphorus. However, because the juice contains a certain amount of water, it is unstable and easy to ferment and mold. Therefore, special attention should be paid to the shelf life and storage conditions of such drinks, and only those that meet the hygienic quality can be drunk.
