Preparing technology and sterilizing method of fresh dendrobium juice

Abstract

The invention discloses a preparing technology and sterilizing method of fresh dendrobium juice. The preparing technology includes the following steps that dendrobium serves as a raw material and is juiced, aseptic packaging sealing and vacuum degassing are carried out, then ultra-high-pressure non-thermal sterilization is carried out, and the fresh dendrobium juice product is obtained. The preparing technology and sterilizing method belong to the technical field of food processing, and the technical scheme is provided for overcoming the adverse effects of existing processing on the taste of the dendrobium juice, large losses of nutrient ingredients and large energy consumption. The fresh dendrobium juice is subjected to non-thermal sterilizing at the normal temperature with the ultra-high pressure technology, and the commercial aseptic application requirements are met; meanwhile, the problems that in traditional thermal sterilizing processing, due to high temperature sterilizing, the taste and the flavor of the product are lowered, and losses of nutrient ingredients are caused are effectively solved, and the effective ingredients, the natural flavor and the nutrient value in dendrobium are preserved to the maximum degree. The dendrobium juice obtained with the preparing technology and sterilizing method is a pure-natural green product, the preparing technology is simple, no preservatives are added, the original flavor of dendrobium is kept, and the high health-care function and the high medicinal value are achieved.

Description

technical field [0001] The invention relates to a preparation method of a beverage, in particular to a beverage processed from dendrobium as a raw material and a sterilization method thereof, belonging to the technical field of beverage processing. Background technique [0002] With the continuous improvement of living standards and health awareness, people's requirements for high-quality fresh health drinks are also getting higher and higher. It is of great significance to develop "zero additive" health drinks that do not contain preservatives and additives. [0003] Dendrobium is the general name of various medicinal plants of the genus Dendrobium in the family Orchidaceae. The main active ingredients are water-soluble polysaccharides, lipid alkaloids, free amino acids and various trace elements, etc., which can improve the immune function of the human body and have the functions of nourishing yin and detoxification. , anti-cancer, anti-fatigue, anti-radiation, anti-hypoxi...

AI Technical Summary

Problems solved by technology

[0004] Compared with dry products of Dendrobium, the content of total alkaloids and polysaccharides in fresh Dendrobium is higher than that of dry products, and its immune function is also better than that of dry medicine, which also verifies the characteristics of Dendrobium "live is excellent"; when using Dendrobium, often take fresh Juice consumption, pay attention to "fresh products first", fresh juice maintains the original nature and taste of natural medicines, smells, and has the characteristics of strong moisturizing properties, but fresh juice is difficult to preserve, thus limiting the market. Application, such as the existing patent application number is "201310238165.8", the name is "a preparation method of Dendrobium candidum puree beverage", the application number is "201110233761.8", the name is " A kind of dendrobium beverage and preparation method thereof ” and the application number is “201010583151.6” and the title is “a method for making fresh juice of Dendrobium candidum” and other public dendrobium beverage preparation methods are all sterilized by high temperature or high pressure, which will easily cause the loss of many heat-sensitive substances and cannot be well preserved. The original nutritional ingredients are easy to change color and taste, and most of the above methods add additives, and the prepared dendrobium beverage can not keep the original taste. Therefore, it is necessary to develop a new dendrobium beverage that can maintain the original nutritional ingredients and without any additives.
