Method for preserving high-moisture tartary buckwheat seeds through pepper essential oil

Abstract

The invention provides a method for preserving high-moisture tartary buckwheat seeds through pepper essential oil. The method comprises the steps that the tartary buckwheat seeds are dried under a mild condition to obtain the tartary buckwheat seeds with the moisture content being 16%-18%; the obtained tartary buckwheat seeds are packaged into a corner bracing bag formed by processing a compositepackaging film made of polyvinylidene chloride / nylon / non-tensile polypropylene, and the corner bracing bag is filled with a slow-release fresh-keeping bag which is obtained in modes that the pepper essential oil and a beta-cyclodextrin aqueous solution are mixed, and pepper essential oil microcapsules obtained through stirring, still standing, vacuum filtration and drying to the constant weight are loaded into a filter bag; and finally, vacuum packaging is performed. According to the method, when the tartary buckwheat seeds are dried in mild and dry conditions till the moisture content is 16%-18%, the high-moisture tartary buckwheat seeds are packaged, and compared with the packaging result of a vacuumizing packaging method in the prior art, under the same storage condition, the method reserves the color and controls microbial growth effectively, and improves the quality of the high-moisture tartary buckwheat seeds.

Description

technical field [0001] The invention relates to a preparation and packaging method of tartary buckwheat seeds, in particular to a method for preserving high-moisture tartary buckwheat seeds by using prickly ash essential oil, and belongs to the technical field of fresh-keeping packaging of miscellaneous grains. Background technique [0002] Tartary buckwheat is a rare medicinal and edible crop in nature. It is rich in nutrition and has good edible value, nutritional value and medicinal value. It is a kind of miscellaneous grains favored by the public. Active ingredients such as catechin, compared with several main components of sweet buckwheat at the same time: protein tartary buckwheat is 1.7 times higher than sweet buckwheat, fat is 1.6 times higher, and rutin is 12.14 times higher. Compared with other major grains, its protein and fat are higher than wheat flour and rice, vitamin B 2 It is 2 to 10 times that of rice and corn flour. Rutin and chlorophyll are incomparable...

Problems solved by technology

Therefore, it can be used as food preservation. For example, the publication number is CN106192209, and the name is a nanofiber film containing a composite antibacterial agent and its preparation method and application. The preparation method of the invention is: the mass fraction is 5%~10% Add β-cyclodextrin with a mass fraction of 1%~3% to the polyvinyl alcohol solution, stir at 35~75°C for 10~30min; Stirring at low temperature for 1~3h; adding lysozyme with a mass fraction of 0.05%~0.5%, stirring at room temperature for 0.5~1h, to obtain an electrospinning solution; preparing the obtained electrospinning solution into a film through an electrospinning process to obtain the Composite antibacterial nanofiber film. When the method uses pepper essential oil in the field of food packaging materials, the use of lysozyme in conjunction with pepper essential oil is expensive, and polyvinyl alcohol solution is a non-food-grade raw material. If it is used to pack tartary buckwheat seeds, Therefore, it is necessary to seek a simple and low-cost high-moisture tartary buckwheat seed preparation and packaging method
