Rapid drying method for red dates

Abstract

The invention discloses a rapid drying method for red dates. The method particularly comprises the steps of S1, raw material selection, wherein the red dates with large size, round and unbroken shape,thick pulp, small kernel, high dry matter content, rich aroma, light astringency and 80-90% of maturity are selected; S2, raw material pretreatment comprising the following processes of (1) fruit picking, wherein firstly, branches, leaves and fruit stems are removed, and then rotten fruits, cracked fruits and fruits with diseases and pests are removed; (2) classified screening, wherein fruits areclassified according to sizes by using a classifying screen of a classifier, so that the sizes of the fruits in a same oven are as uniform and consistent as possible; (3) cleaning, wherein the fruitsare put into a bamboo basket and immersed in flowing spring water, dust and other dirt on the surfaces of the fruits are washed away, and then the fruits are get out and dried. The rapid drying method for the red dates has the advantages that the red dates are dried by adopting a method combining sun drying and baking, color-protecting treatment is carried out by adopting a color-protecting agent, and a water jet is used for jetting a small amount of water during sun-curing, so that the fruit peel returns to red naturally, thereby greatly improving the sensory quality of the dried red dates.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for quickly drying red dates. Background technique [0002] The existing drying methods for jujubes are usually insolation and drying jujubes directly through a dryer. When these two methods are used for drying, there is a common problem of severe browning of the finished pericarp after drying, which is a huge problem. Affect the sensory quality of dried jujube. [0003] Therefore, it is necessary to invent a kind of fast drying method of red dates to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a rapid drying method for jujubes. The jujubes are dried by the method of drying in the sun and baking, and the color-protecting agent is used for color-protecting treatment of the jujubes. The sprinkler sprays a small amount of water to make the peel turn red naturally, so as to solve the problems rai...
