Embodiment 1

[0027] Embodiment 1, choose local ripe, fresh lychee 10Kg, and lychee flesh is thick, and core is little, is suitable for making lychee dry, does not process through filling, also can form after drying. After treatment, it has good plumpness and is in the shape of "lantern meat", with suitable sweet and sour, and full of lychee fragrance. Lychee pulp is obtained by washing, peeling, and pitting the lychees, and the lychee pulp is guaranteed to be intact and not damaged. To harden the lychee pulp, put the lychee pulp into 0.2% NaHSO 3 , 0.1% citric acid, 0.2% CaCl 2 Soak in the aqueous solution for 2 hours; the hardened lychee pulp can keep the shape in the subsequent saccharification and drying, and ensure the smooth processing of preserved fruit. To scald the hardened lychee pulp, put the hardened lychee pulp into hot water at 95°C for 3 minutes; take it out and drain at room temperature. Blanching can inactivate enzyme activity and prevent enzyme browning; stabilize or im...

Abstract

The present invention belongs to the field of litchi chinensis processing and relates to a processing method of dried litchi chinensis, which comprises the following steps in sequence: selecting fresh litchi chinensis with thick flesh and small kernels, and cleaning, peeling, and removing the kernels of the litchi chinensis to obtain the litchi chinensis fruit pulp; soaking the litchi chinensis fruit pulp in an aqueous solution of 0.2% NaHSO3 , 0.1% citric acid, and 0.2% CaCl2 for 2-3 hours; blanching the hardened the litchi chinensis fruit pulp in a hot water at 90-100 DEG C for 2-3 min; then placing the litchi chinensis fruit pulp in a cold storage at -20 to 0 DEG, rapidly decreasing the water activity of the litchi chinensis fruit pulp to be less than 0.6 and the moisture content to be lower than 50% by using a dehumidifier; and finally putting the litchi chinensis fruit pulp in a drying oven, hot air drying at 50 DEG C for 8-10 hours with a hot air flow rate of 1-2 m / s until the moisture content is lower than 25%, and then cooling and packaging. The present invention provides a processing method of dried litchi chinensis with full appearances and good color, and the processing method has low processing costs.

Description

technical field [0001] The invention relates to the field of litchi processing, in particular to a processing method of dried litchi. Background technique [0002] Litchi is a famous southern specialty fruit in my country. It is tender and juicy, rich in fragrance, rich in various nutrients necessary for human body, and has nourishing and medicinal value.
