Fresh dendrobium officinale freeze drying processing method

Abstract

The invention discloses a fresh dendrobium officinale freeze drying processing method. The method comprises the following steps: 1) raw materials selection and processing; 2) segmenting; 3) spreading on a plate and loading; 4) performing quick-freezing; 5) adding and enrichment of hydrolase (6); 7) performing secondary freeze-drying; 8) discharging; 9) sorting a semi-finished product; 10) packaging; 11) obtaining the finished product and warehousing; and 12) eating. The method clears the requirement of dendrobium raw materials, quantifies the indexes of cut-out length, loading amount, a hydrolase enrichment method, quick-frozen temperature and time, a freeze-drying curve program and discharging, semi-finished product sorting work and environment in each step, a whole processing step is controllable, the nutrient composition, shape, natural color, tissue structure and flavored substance of dendrobium officinale can be kept for the dendrobium officinale product, surface hardening is not generated on the product, the tissue is in a porous sponginess state, the water reabsorbing capacity is good, eating is convenient, rebound is realized by immersion, the eating is convenient, weight is light, preservation resistance is realized, no especial requirement is generated on ambient temperature, and the fresh dendrobium officinale can be kept for about 2 years under dark condition. The method has important meaning for developing product diversity, increasing the market competitiveness, and increasing the economic benefit.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for freeze-drying and eating fresh dendrobium officinale. Background technique [0002] Dendrobium is a famous and precious Chinese medicinal material, containing more than 10 kinds of alkaloids. The water-soluble polysaccharides contained in it can significantly enhance immunity, anti-aging, anti-radiation, etc., and are effective for digestive system, respiratory system, cardiovascular system and eye diseases. Obvious curative effect. The medicinal materials processed from dendrobium are expensive and are very valuable medicines and tonics. [0003] In recent years, due to the improvement of living standards, the traditional medicinal and functions of Dendrobium have been paid attention to, the production technology has also been developed, and the production scale is expanding. At present, there are dendrobium cultivation or experimental cultivation in Zhejiang, Yunna...

Problems solved by technology

At present, Zhejiang leads the country in processing and marketing. The main commodity forms of Dendrobium on the market are maple bucket, powder, capsule, etc.; and these products are all made from its dried Dendrobium, and the dried Dendrobium is made from fresh strips of Dendrobium. It is obtained by natural drying or drying. The common feature of processing is that fresh dendrobium needs to be heat-treated, which greatly damages active ingredients such as alkaloids and water-soluble polysaccharides in dendrobium, resulting in loss of medicinal efficacy of dendrobium; moreover, dendrobium candidum cells The cell wall of Dendrobium officinale is mainly composed of cellulose and pectin, which greatly hinders the penetration of water-soluble polysaccharides, the functional component of Dendrobium officinale
