Description

Agent keeping vegetable fresh, preparation method and its fresh-keeping of vegetables method
Technical field
The present invention relates to agricultural products storage and preservation technical field, more particularly to a kind of agent keeping vegetable fresh, preparation method and its Fresh-keeping of vegetables method.
Background technology
China is vegetable basket maximum in the world.Vegetables are before and after harvesting due to various physiological agings, microorganism and cause of disease The reason such as the infringement such as bacterium and residing environment change, it is easy to occur the phenomenon such as brown stain, softening, rotten, rotten.Study vegetable The preservation technology of dish, extends its storage & fresh-keeping period, is the significant problem that fresh-keeping of vegetables field needs to solve.
The preservation method of current vegetables mainly has two kinds of physical method and chemical method.Physical method such as controlled atmosphere and gas Adjust packing technique, radiation preservation technology etc. to be required to special equipment, cost higher, be not suitable for promoting the use of.Chemical method is more Using chemical preservative.Because vegetable surface product is big, organize tender and crisp, and surface is mostly rough, easily causes the residual of antistaling agent Stay, so that environmental pollution and food hidden danger can be caused.Therefore, the direction that natural bio-preservative is Future Development is researched and developed.
Chinese mugwort (Artemisia argyi) also known as great Ye Chinese mugworts, Qi Ai etc., are composite family perennial herb or slightly into fruticuli Shape.Chinese mugwort is compared with common Chinese mugwort, and plant is tall and big, plant Chuck Steak containing volatilization, is given off a strong fragrance.For the relatively common Chinese mugwort of Chinese mugwort not only Yield is high, quality is good, and Chinese mugwort leaf contains multiple compounds.Main Ingredients and Appearance in Chinese mugwort leaf is ethyl acetate, cineole, water The chemicals such as amphene, camphor, terpinol, Eucarvone are closed, the oil yield of the essential oil of Chinese mugwort is twice typically ended.Meanwhile, Chinese mugwort Containing absinthol and isothujone, and general Ai Ze has no this composition.Secondly Chinese mugwort has a variety of works such as good antibacterial, antiviral With.In addition, Chinese mugwort is also a kind of good food, in Chinese traditional food, has and much made with Chinese mugwort as primary raw material Food, and fresh and tender wormwood leaf and bud are also for vegetable consumption.Therefore, Chinese mugwort is a kind of bio-preservative for extracting safety and Health Excellent materials.
The content of the invention
