Abstract

The invention discloses a normal-temperature edible film coating fruit and vegetable fresh keeping agent and a using method thereof. The normal-temperature edible film coating fruit and vegetable fresh keeping agent comprises the following components in percentage of 83.0-91.0% of pure water, 2.0-6.0% of glycerine, 2.0% of folium eucalypti oil, 1.0-3.0% of modified starch, 1.0-3.0% of glycerol monostearate, 1.0-3.0% of sucrose fatty acid ester, 0.4-1.0% of calcium chloride and 0.2-0.8% of arabic gum. The normal-temperature edible film coating fruit and vegetable fresh keeping agent can be usedfor fresh keeping of wax apples after the wax apples are picked, the phenomena of moisture dissipation, stiffness reduction, rot and the like of the picked wax apples are avoided, and the normal-temperature edible film coating fruit and vegetable fresh keeping agent can be used for other fruits and vegetables of apples, citruses, okra and the like.

Description

technical field [0001] The invention relates to the field of post-harvest preservation of fruits and vegetables, in particular to an edible fresh-keeping agent for fruits and vegetables with a film coating at normal temperature and a use method thereof. Background technique [0002] Fruits and vegetables are the main sources of nutrients such as minerals, vitamins, and dietary fiber in human food. However, due to their regional and seasonal production, fresh fruits and vegetables maintain high physiological activity after harvesting, and have a large water content. Rot and deterioration bring great difficulties to the storage and transportation of fruits and vegetables. Therefore, the study of fruit and vegetable preservation has important practical significance and has become a hot spot in the field of agricultural engineering. [0003] Edible film preservation is to artificially coat a layer of film on the surface of fruits and vegetables. The film can properly block the ...
