Preservative and preservation method for dendrobium candidum

Abstract

The present invention discloses a preservative for dendrobium candidum. The preservative comprises the following components in percentage by mass: 1-2% of a propolis extract, 2-4% of sodium dehydroacetate, 0.5-1.5% of tea polyphenol and the balance being water. The present invention discloses a preservation method for dendrobium candidum, comprising the following steps: preparation of the propolis extract; preparation of the preservative; pre-treatment of dendrobium candidum fresh strips; preservation treatment; package; radiation treatment; and storage of the treated dendrobium candidum fresh strips at a temperature of 0-4 DEG C. The raw materials of the preservative adopted by the present invention are environmentally friendly, have no harm to human health, and have a good preservation effect. According to the preservation method disclosed by the present invention, radiation and a refrigerated preservation technique are adopted, so that the features of good preservation effect, safety and non-toxicity are achieved, and the problem of short preservation time of the dendrobium candidum fresh strips is solved. Shelf life of the dendrobium candidum fresh strips treated by the preservation method of the present invention is greatly prolonged, the dendrobium candidum fresh strips can be stored for more than half a year without deterioration, and the fresh strips after long-term preservation are full and low in weight loss rate.

AI Technical Summary

Benefits of technology

This patented inventor uses different techniques such as propolis extraction from plants or created by burning leaves with bacteria called Phebrellum brasilians (PGA). These methods help protect against harmful microorganisms like fungi, yeast, molds, spores, pollen grains, fecal matter, insect larvae, worms, nematodes, ticks, lice, seaweeds, pests, weevils, birds, fish, rodents, animals, humans, and their environment around them. By adding these treatments into foodstuffs containing certain ingredients, they improve its quality and extend it's lifespan over time while maintaining good nutritional value.

Problems solved by technology

Technologies described by this patented patent involve extracting dysprosium vitae (a type of root) berries called Tripterygii or Trifoliate Root). These plants are found throughout North America but they may be threatened because overfishing techniques like mineral water flushing cannot prevent their consumption. To address these issues, researchers developed various processing technics aimed towards improving storage stability and flavoring natural ingredients without compromising beneficial properties.
