Application of seaweed oligosaccharide in fruit preservative preparation and method thereof

Abstract

The invention provides an application of seaweed oligosaccharide in fruit preservative preparation and a method thereof, and relates to the seaweed oligosaccharide. The oligosaccharide is obtained by directly degrading asparagus through an enzyme series generated by Flammeovirga Pacifica H2, and is a mixture of 4-8 sugars. The invention further provides a method for carrying out fruit preservation by utilizing the oligosaccharide. The method comprises the following steps of: placing fruits at a ripe period into the seaweed oligosaccharide with the concentration of 80-160 mg / L to be immersed for 1-5 minutes; and taking out and drying, and placing into a refrigeration storage to be stored or storing at a room temperature. The seaweed oligosaccharide prepared by the asparagus can obviously prolong a storage period of the fruits and the shelf life of the fruits; secondly, the method is simple, the cost is low and the popularization and application can be easy to realize; and thirdly, the used oligosaccharide belongs to a natural extractive, damages to a human body caused by using a chemical preservative is avoided, and the environment can not be polluted.

Description

technical field [0001] The invention relates to a seaweed oligosaccharide, in particular to an application of the seaweed oligosaccharide from asparagus in the preparation of a fruit preservative and a method thereof. Background technique [0002] my country is a big producer of fruits and vegetables, with an annual output of about 300 million tons of vegetables and more than 60 million tons of fruits, ranking among the top in the world. The loss rate on logistics links such as storage is 25% to 35%. According to statistics, 80 million tons of fruits and vegetables rot every year in my country, with a total value of 80 billion yuan. China is the most important origin center of fruit trees in the world, and the variety and varieties of fruit trees are the most in the world. In 2005, the total output of fruit in the country exceeded 160 million tons, and the total planting area reached 10.055 million hectares. However, due to the relatively concentrated collection of varieties...

Problems solved by technology

In 2005, the total output of fruit in the country exceeded 160 million tons, and the total planting area reached 10.055 million hectares. However, due to the relatively concentrated collection of varieties and the continuous increase in the number of fresh sales, the market pressure tends to increase

[0005] But so far there is no report that the oligosaccharides used are chitosan or chitosan oligosaccharides derived from chitin
