Abstract

The invention discloses a processing technology of canned grapes suitable for children to eat. The technology includes a processing procedure of: material selection; cleaning and pruning; peel and stone removing; color protection; preheating; soup preparation; canning and sterilization. The color protection treatment is performed under a vacuum condition. The soup preparation process includes: filtering clean water with four layers of gauze, boiling the water, then adding white granulated sugar, adding 1.5% citric acid after the sugar is dissolved, and keeping the temperature of the soup above 90DEG C. The color protection treatment is carried out under a vacuum condition, and experiments prove that the processing operation can reach a good color protection effect, the original color of grapes can be kept without adding any pigment, and time can be saved under the vacuum condition. Also, no pigment or other chemical component is added in the preparation process of the solution involved in the invention, the solution is sweet and sour, and palatable. Therefore, the making process disclosed in the invention involve no pigment, preservative or other additive, and the obtained canned grapes have good color and taste, is healthy and nutritious, thus being especially suitable for children to eat.

Description

technical field [0001] The invention relates to canned food, in particular to a processing technology of canned grape suitable for children. Background technique [0002] Canned grapes are sweet and sour, with soft and delicate flesh and small size, which are loved by children. [0003] However, during the processing of canned grapes, in order to make the grapes have a complete, crystal-clear, bright-colored appearance, a coloring process is adopted, that is, artificial pigments such as carmine and lemon yellow are used for dyeing. Children are in the period of growth and development, their internal organ functions are relatively fragile, their nervous system is not yet fully developed, and they are sensitive to chemical substances. If they eat food containing synthetic pigments for too long, it will affect the impulse conduction of the nervous system and stimulate the brain nerves to appear. Symptoms such as restlessness, emotional instability, inattention, poor self-contr...
