Description

Fresh-keeping method for okra
Technical Field
The invention relates to a storage and preservation technology of fruits and vegetables, in particular to a preservation method of okra.
Background
Okra (Abelmoschus esculentus) belongs to annual herbaceous plants of okra of Malvaceae, has tender fruit meat, smooth mouthfeel and unique flavor, and has high nutritional value and certain medical and health care functions because fruits contain abundant viscous polysaccharide, protein, vitamins, flavone and the like. With the increasing attention on green and organic vegetables in society, okra has gained more and more attention as one of the vegetables with both nutrition and health care functions. However, due to the fact that the okra fruits have large surface areas and fine fluff, and lose edible value due to dehydration and aging after picking, consumption and circulation of the okra are greatly influenced by the factors, and therefore the okra is subjected to fresh-keeping treatment in a safe and effective mode, and application quality of the okra in the aspects of storage, fresh keeping, processing and the like can be improved.
Gamma-aminobutyric acid (GABA) is a four-carbon nonprotein amino acid, widely exists in plants, animals and microorganisms in a free state, has no toxic or side effects on the environment and human health when used on plants or fruits and vegetables, has been approved for use in foods as a novel food functional factor, and has been approved and confirmed by the U.S. environmental protection agency. Therefore, in recent years, the research on GABA has become a new focus. Researches show that GABA can effectively help organisms to resist external stress and reduce harm caused by active oxygen. Exogenous GABA can promote the accumulation of endogenous GABA and proline in fruits and vegetables such as peaches, melons, bananas and the like, increase the enzyme activity of an antioxidant system, maintain the energy level, reduce the accumulation of active oxygen and membrane lipid peroxidation and improve the stress resistance of the fruits.
The invention optimizes the formula of the okra before the okra is pre-treated and the harvested okra is treated by GABA, and discusses a green, environment-friendly, safe and effective okra preservation method.
Disclosure of Invention
The invention relates to a fresh-keeping method of okra, belonging to the storage and fresh-keeping technology of fruits and vegetables. Aims to provide a practical, safe and effective okra preservation technology, which can not only make full use of the existing commercial technology to rapidly realize industrial production, but also ensure the quality of the stored products and prolong the shelf life of the products to the maximum extent.
The method comprises the following specific steps:
(1) pretreatment: selecting okra with consistent size, uniform color and no mechanical damage or pest as an experimental material, cleaning with clear water, and airing for later use.
(2) And (3) sterilization treatment: soaking the okra pretreated in the step (1) in 0.1-0.5% of Fenker for 1-3 min.
(3) Fresh-keeping treatment: and (2) fully soaking the okra in the step (1) in a gamma-GABA solution of 0 mmol/L-15 mmol/L for 3min, and naturally airing the okra in a ventilated place after the coating is uniform.
(4) And (3) storage at normal temperature: and (4) storing the okra obtained in the step (3) at room temperature (20-26 ℃).
The invention provides a safe and effective okra preservation technology. After 18 days of storage, okra can maintain high water content, chlorophyll content is increased by 37%, and VCThe content is increased by 69%, and the fresh-keeping effect is obvious.
