Abstract

The invention relates to a processing method for preventing freeze-dried waxberry flesh from falling off. The processing method comprises the steps of cleaning fresh waxberries, disinfecting, stewing, softening, quick-freezing, vacuum freezing and drying and discharging materials; the flesh of the produced dry waxberries is compacted with kernels and has small possibility of falling off due to regulation on vacuum degree during the stewing, softening and vacuum freezing and drying processes. According to the processing method disclosed by the invention, the prepared freeze-dried waxberries are bright red uniformly and consistently; the flavor can be kept perfectly; the color retention time is long; the flesh has small possibility of falling off; furthermore, the freeze-dried waxberry flesh has the special smell of the waxberries, tastes soft, has an obviously mellow flavor and does not have other peculiar smell, and other external impurities are avoided; the freeze-dried waxberry flesh is convenient to eat.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for preventing freeze-dried red bayberry pulp from falling off. Background technique [0002] Red bayberry is mainly distributed in East China and Hunan, Guangdong, Guangxi, Fujian and other regions, and is known as "a piece worth a thousand pieces of gold". Red bayberry fruit is bright in color, rich in juice, sweet and sour, and has high nutritional value. However, it has the disadvantages of short production season and short shelf life. It is generally stored at room temperature for no more than 2 days, and transportation is extremely inconvenient, which seriously affects the promotion of bayberry products. And the form that most of red bayberry is made into preserved fruit, its local flavor, nutritional labeling run off seriously. After adjusting the freeze-dried bayberry processing technology, the flavor of bayberry can be well preserved and the problems ...
