A method for preparing natural fruit vegetables antistaling agent using capsule technique

Abstract

The present invention belongs to a method for preparing nature fruit vegetable antistaling agent using capsule technology. The mixing ratio as well as method is: getting 0.01 to 2 percent of foliage oil, 0.1 to 5 percent of microcapsule wall material, adding water of one kilogram and mixing them fully to obtain fruit vegetable antistaling agent; the fruit vegetable antistaling agent is coated fruit exterior, forming a translucence film composed of foliage oil and microcapsule after drying, so as to reach antistaling; the chitose and the konjak amylose etc. dissolve slowly in water, it is need to heat or add auxilytic agent into the water, the auxilytic agent includes: citric acid and vinegar acid, the ratio is 0.5 percent to 2 percent, the heating temperature is 20 DEG C to 90 DEG C. The method is that the fruit vegetable antistaling agent is nature safe and high effect, which not only solve the problem of antistaling as well as storing effectively, but also the leftover on the fruit has no toxicity, and reaching edible standard, which solves the problem that the medical antistaling agent has remnant poison and can improve the economy efficiency of fruit vegetable.

Description

technical field [0001] The invention belongs to a preparation method of a fruit and vegetable fresh-keeping agent, a method for preparing a fresh-keeping agent by using pure natural materials, in particular a method for preparing a natural fruit and vegetable fresh-keeping agent by using capsule technology. Background technique [0002] At present, our country's fresh-keeping technology for fruits and vegetables has been in a relatively backward state, resulting in a large number of fruit and vegetable products rotten or dehydrated, and the quality has declined, causing huge losses to producers and operators, and seriously restricting the development of my country's fruit and vegetable planting industry. Further development, for this, my country adopts the method of chemical antistaling agent more at present, but this kind of method has residual toxicity mostly, is difficult to solve, and to this, also does not have very ideal solution at present.

Problems solved by technology

[0003] In order to solve the backwardness of fruit and vegetable fresh-keeping technology in our country, the present invention provides a method for preparing natural fruit and vegetable fresh-keeping agent by using microcapsule technology. Not only can it effectively solve the problem of fresh-keeping and storage of fruits and vegetables, but also the residues on fruits and vegetables have no toxicity, and can meet the edible standard. It can completely solve the problem of residual toxicity of chemical preservatives, and can greatly improve the economic benefits of fruits and vegetables. Therefore, It has been widely promoted and applied in the storage and transportation of fruits and vegetables at home and abroad.
