summary of the invention:

The object of this invention is to provide the processing method that a kind of Yanjin blueberry is dry, realize the deep processing comprehensive utilization of blueberry raw material.

The present invention solves the technical scheme that its technical problem takes:

The processing method that Yanjin blueberry is dry, is characterized in that: adopt → the processing technology of caustic dip rinsing → sulphuring → dry → ease back → packaging → finished product of selecting materials → clean, its major processing steps is:

A, to select materials and cleaning: select color of the leather light, even particle size, taste is sweet, juice is many kind, remove and go rotten, immaturely conform to ciruela, then load basket, in tank circulating water cleaning 4-6 time, removal impurity;

B, caustic dip rinsing: blueberry is placed on 0.06-0.08% and boils in sodium hydroxide solution blanching a moment, then in clear water, alkali lye is removed in abundant rinsing, is placed in basket and drains 30 minutes, controls water purification and divides;

C, sulphuring: fruit is loaded drip pan, send sulphur house to, smoked 1-2 hour;

D, oven dry: be layered on equably on drip pan by the blueberry after sulphuring, send drying room to and carry out drying; Starting temperature controls at 60-65 DEG C, when waiting slightly dry, temperature is risen to 80 ~ 88 DEG C, takes out, choose the fruit of not drying after 5-6 hour, is placed on another drip pan again dry;

E, to ease back: pour in wooden case by dry for blueberry, ease back 10-12 days, makes water balance inside and outside fruit, quality is soft;

F, packaging: sprinkle a little salt by dry for the blueberry after easing back, reinstall in carton after packing with plastic film food bag, get final product export trade.

Beneficial effect: the Yanjin blueberry that the present invention obtains is done, inside and outside water balance, soft or hard appropriateness, has the local flavor that blueberry is sour-sweet.This product is rich in multivitamin, is conducive to reducing cholesterol, atherosclerosis, and the effect having develop immunitypty, softening blood vessel, beautifying face and moistering lotion and delay senility is a kind of local delicacies of nutrient health.
