Preservation method for Chinese mahogany sprouts

Abstract

The invention discloses a preservation method for Chinese mahogany sprouts. The preservation method comprises the following steps: fumigation treatment: 1-methylcyclopropene is adopted to perform fumigation treatment on the Chinese mahogany sprouts, and the Chinese mahogany sprouts are subject to enclosing treatment at room temperature for 12-16 h; modified atmosphere packaging: the Chinese mahogany sprouts after fumigation treatment are packaged into preservation bags, wherein the carbon dioxide concentration is 5%-10% and the oxygen concentration is 10%-15% during the preservation period; refrigeration: the packaged Chinese mahogany sprouts are subject to storage at a specific temperature, wherein the storage temperature is 2-5 DEG C, and the relative humidity is higher than 90%. The preservation method combines three preservation functions of fumigation treatment, modified atmosphere packaging, and refrigeration, so as to obviously improve the preservation effect on the Chinese mahogany sprouts; the preservation period can be prolonged by 1 month in terms of the Chinese mahogany sprouts which are susceptible to decomposition; the unique scents of the Chinese mahogany sprouts are maintained, the color and the structure are not obviously changed, the decomposition rate is controlled within 5%, the weight loss rate is less than 3%, the preservation effect is obvious, so that the method has an obvious market popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of plant fresh-keeping, and in particular relates to a plant fresh-keeping method used in the process of storage, transportation and packaging of Chinese toon buds after harvesting.
