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
The present invention relates to a kind of can, particularly relate to the processing technology of the canned grape that a kind of children of being suitable for eat.
Background technology
The canned grape sweet and sour taste, meat is soft fine and smooth, and stature is small and exquisite, by children are liked.
But canned grape has particle integrity, outward appearance sparkling and crystal-clear, bright in colour in order to make grape in process, adopted painted processing technology, namely adopts artificial color such as carmine, lemon yellow to dye.The juvenile is in growth and development stage, the intracorporeal organ function ratio is fragile, nervous system development is still unsound, to the chemical substance sensitivity, if too much the feed after for a long time contains the food of synthetic dyestuff, the impulse conduction of the system that can affect the nerves stimulates cerebral nerve and restless, emotional lability, absent minded, symptom such as self-control is poor, thought rebel, behavior are too drastic occur.Edible artificial color also can influence children ' s intelligence development.The long-term edible children intelligence that may make descended 5 fens.Because children's's liver detoxification function, RE function are not well established, edible synthesized coloring matter causes detoxifcation material in a large amount of consumer, disturbs eubolism function in the body, thereby causes diarrhoea, abdominal distension, stomachache.
In addition, in order to increase mouthfeel, tend in can with addition of soup stock, the manufacture craft of soup stock can add additives such as pigment, essence, antistaling agent, defoamer, the child who has eats up grape berry, also the soup juice in the jar can be drunk, and this health for children all is harmful.
Summary of the invention
The purpose of this invention is to provide the processing technology of the canned grape that a kind of children of being suitable for eat, manufacturing process is not added pigment, anticorrisive agent etc., and is additive-free, and the color and luster mouthfeel is all good, health-nutrition.
For achieving the above object, the technical solution used in the present invention is:
The processing technology of the canned grape that a kind of children of being suitable for eat comprises and selecting materials; Clean, prune; Peeling, stoning; Protect look; Preheating; Join soup; The process of canned sterilization; The described look that protects is handled and to be carried out under vacuum condition; The described soup process of joining is: clear water will add white granulated sugar with four layers of filtered through gauze behind the water boil, treats that sugar dissolving back adds 1.5% citric acid, and soup juice temperature is more than 90 ℃.
Preferably, described soup juice temperature is 94 ℃.
Further improve, described canned sterilization process carries out under vacuum condition.
The look that protects in the processing technology of the present invention is handled and to be carried out under vacuum condition, and through verification experimental verification, such process operation makes that to protect chromatic effect good, need not to add pigment and can keep the original color and luster of grape, and can save time under the condition of vacuum.And soup layoutprocedure non-pigment of the present invention and other chemical compositions are added, sweet and sour taste.Therefore, manufacturing process of the present invention is not added pigment, anticorrisive agent etc., and is additive-free, and the color and luster mouthfeel is all good, and health-nutrition is particularly suitable for children and eats.
The specific embodiment
The present invention will be described below in conjunction with embodiment.
The processing technology of the canned grape that a kind of children of being suitable for of the present invention eat,
Comprise and selecting materials: used grape fruit should be fresh full, maturity is that 7-8 becomes, it is slightly faint yellow that color and luster is cyan, do not have to go rotten no disease and pest, the fruit horizontal stroke is through requiring more than 22 millimeters, band handle grape, grape should be from qualified raw material sites, and qualified certificate of origin is provided, the can mouthfeel that the grape of this condition is made, outward appearance etc. are all better, and are convenient to process operation;
Clean, prune: soaked 6 minutes with 0.015% liquor potassic permanganate, clear water is rinsed well then; Grape is cut into simple grain, and the carpopodium place leaves the 1mm carpopodium, and is totally attractive in appearance;
Peeling, stoning: grape scalds 5-10 second in 88-93 ℃ hot water, looks fruit shape size and maturity and just grasps the blanching degree, is advisable with easy peeling, be cooled to immediately behind the hot soup under the normal temperature, operation is not in time overstock after the blanching, such operation peeling is easy, and the efficient height is effective; The cooled grape of blanching is manual to begin peeling from carpopodium, does not injure pulp, discloses after base of fruit is removed fruit stone with grape to be soaked in the circulating water, and pulp must not surface;
Protect look: pulp is placed in 0.05% ascorbic acid and the 0.09% citric acid mixed liquor, 4-6 hour, under vacuum condition, carry out, grape berry need not to add pigment can keep original color and luster;
Preheating: 88 ℃ of water temperatures, 4 minutes;
Join soup; Clear water is with four layers of filtered through gauze, white granulated sugar will be added behind the water boil, treat that sugar dissolving back adds 1.5% citric acid, soup juice temperature is more than 90 ℃, such technology, and the canned grape sweet mouthfeel degree of making is suitable, be particularly suitable for children's taste, preferably, soup juice temperature is 94 ℃, and the sour-sweet degree of soup juice is best.
Canned sterilization: under vacuum condition, in pulp and soup tank filling, temperature sterilization in 98 ℃, 40 minutes, such bactericidal effect is better, experiment showed, that the holding time is more of a specified duration.
The look that protects in the processing technology of the present invention is handled and to be carried out under vacuum condition, through verification experimental verification, such process to protect chromatic effect good, need not to add pigment and can keep the original color and luster of grape, and save time.And soup layoutprocedure non-pigment of the present invention and other chemical compositions are added, sweet and sour taste.Therefore, manufacturing process of the present invention is not added pigment, anticorrisive agent etc., and is additive-free, and the color and luster mouthfeel is all good, and health-nutrition is particularly suitable for children and eats.
