Method for preparing instant fruit and vegetable solid beverage

Abstract

The invention discloses a method for preparing an instant fruit and vegetable solid beverage and belongs to the technical field of solid beverage. Beef is cooked and filtered, filter liquid is obtained for use, tomatoes, carrots and other fruits and vegetables are cleaned, heated and subjected to blanching with a sodium bicarbonate solution to prevent browning of the fruits and the vegetables in the processing process, the fruits and the vegetables are drained and smashed and then mixed with sodium alginate and tween 80 and ground to obtain fruit and vegetable mixed pulp, then the obtained fruit and vegetable mixed pulp is mixed with the filter liquid, Arabic gum and the like, lactobacillus bulgaricus and streptococcus thermophilus are inoculated, constant-temperature sealed fermentation is conducted, low-temperature sterilization is carried out, vacuum freezing drying is conducted, then the product is smashed, screened and packaged, and the instant fruit and vegetable solid beverage is obtained. The fruit and vegetable pulp is primarily degraded in the probiotic fermentation process, cellular level smashing and fiber bundle breaking are achieved in the later processing process, so dispersity, water solubility and other physical properties of the finished product are improved, nutrients are absorbed more easily, and total-effective utilization of fruits and vegetables is achieved.

Description

technical field [0001] The invention discloses a preparation method of an instant fruit and vegetable type solid beverage, belonging to the technical field of solid beverage preparation. Background technique [0002] With the development of society, people's nutritional requirements for food are getting higher and higher, but it is easy to appear anorexia of fruits and vegetables in young age groups, which will lead to malnutrition such as obesity, lack of trace elements, and vitamin deficiency. At present, edible fruits are mainly eaten fresh, and traditional processing methods have been followed, such as canning, preserved fruit, fruit juice, etc. It is difficult for these products to meet the new requirements of consumers for food. The added value of the product is low, and the products with high added value are even less. Therefore, it is urgent to develop new nutritious fruit and vegetable products with high added value to meet the needs of the market. The functional n...

Problems solved by technology

[0003] The main technical problem to be solved by the present invention is: the traditional fruit and vegetable type solid drinks often use spray drying technology in the preparation process, which cannot achieve cell-level crushing and fiber bundle separation, and the nutrients in fruits and vegetables cannot be effectively separated and absorbed, resulting in To solve the problem of high loss of nutrients, a method for preparing instant fruit and vegetable solid drinks is provided. In the present invention, the beef is boiled and then filtered, and the filtrate is taken for later use. After cleaning tomatoes, carrots and other fruits and vegetables, they are heated with sodium bicarbonate solution. Blanching treatment to prevent browning of fruits and vegetables during the treatment process, drain and crush, then mix and grind with sodium alginate and Tween 80 to obtain a mixed fruit and vegetable slurry, and then mix the obtained mixed fruit and vegetable slurry with the spare filtrate, gum arabic Mix them together, inoculate them with Lactobacillus bulgaricus and Streptococcus thermophilus, ferment them in a sealed container at constant temperature, sterilize them at low temperature, freeze them in a vacuum, dry them in a vacuum, crush them, sieve them and package them to get instant fruit and vegetable solid drinks
