Compounding process and usage of spice oil composition for preserving fruit

Abstract

The present invention discloses compounding process and usage of spice oil composition for preserving fruit. The spice oil composition is compounded with natural spice oils containing rich eugenol, cinnamyl aldehyde, thymol and isosulfocyanate in certain weight proportion as materials, and through mixing. It has high antioxidant and antiseptic effect and no toxicity, and may be used widely for preserving various kinds of fruit. It is diluted with alcohol to form alcohol solution for soaking and coating fruit, or mixed with inert porous powder as carrier, with the absorbing powder being packed in penetrating package and set inside fruit packing box to preserve fruit through fumigation.

Description

technical field [0001] The invention relates to the preparation and application method of a spice essential oil composition used for fruit preservation, and belongs to the field of food chemistry. Background technique [0002] At present, the annual fruit and vegetable loss rate in my country is 25% to 30%, about 75 billion yuan, while the loss rate in the United States is only 1.7% to 5.0%. rate should be reduced to 10% to 15%. According to the conservative estimates of relevant departments, the decay and loss of fruits and vegetables after harvest can almost meet the basic nutritional needs of 200 million people in our country. It can be seen that the development, application and promotion of fresh-keeping technology are of great significance, and the social and economic benefits are obvious. [0003] Due to the poor freshness of the fruit and the difficulty in transportation, the high yield is not good, which seriously affects the income of the fruit farmers. For exampl...

AI Technical Summary

Problems solved by technology

[0003] Due to the poor freshness of the fruit and the difficulty in transportation, the high yield is not good, which seriously affects the income of the fruit farmers.

For example, the output of lychees in Guangdong accounts for more than 60% of the country's total, which is extremely advantageous in production. The period is concentrated in the high-temperature season, so the preservation of litchi has always been a major problem in the fresh-keeping industry. If the fresh-keeping problem is not solved, it is difficult for production advantages to become commodity advantages.

Some fruits have a very short preservation period, only 3 to 5 days. If they cannot be sold in time during the peak harvest period, the fruit will rot on the tree, resulting in an increase in production that cannot increase income, or even increases production and reduces income.
