Abstract

The invention discloses a method for manufacturing a fruit can. The method comprises the following steps of selecting, preprocessing, denucleating, boiling, making soup, sealing, sterile cooling and packaging. The method has the beneficial effects that hawthorn is subjected to pickling processing and alkaline liquor processing, and alkaline liquor is cleaned with clear water at once after processing is finished; the steps can save human and material resources, shortens the cycle of the whole process and increases the yield, the hawthorn is tidily peeled, and the efficiency is obviously increased; as the hawthorn is sourer, the amount of crystal sugar is appropriate and can cover the sourness and cannot be too greasy; less water is put, the thickness of sugar water is ensured, and the taste is better, so that the ratio of water to crystal sugar is 4.5: 1-5.5: 1; fresh milk, coconut juice and pawpaw are put in the soup, and the taste is unique; the fresh milk and the pawpaw have double skin-whitening effects, and often eating can make skin smooth; the coconut juice can make the taste more smooth.

Description

A kind of preparation method of tinned fruit

Technical field

The present invention relates to a kind of tinned fruit, a kind of preparation method of tinned fruit.

Background technology

At present, the preparation method of canned haw basically by select materials, clean, remove the peel, dig nuclear, tinning, batching with soup, seal steps such as sterilization and realize, mainly there is following problem: 1, need expend quite big human and material resources and time, cause the whole processing technology cycle long, cost is high, has caused very big pressure to factory; 2, hawthorn is removed the peel irregular fragile hawthorn, influences the image of product, and efficient is low; 3, batching is simple, generally is syrup, and taste is single, causes taste single, can not satisfy the requirement that popular taste improves day by day.

Summary of the invention

At the problem that above-mentioned prior art exists, the invention provides a kind of preparation method of tinned fruit, can save the man power and material, shorten the cycle of whole technology, improve output, the hawthorn peeling is neat, the efficient height, special taste can beautifying face and moistering lotion.

To achieve these goals, the preparation method of a kind of tinned fruit of the present invention, step is as follows:

(1), selects: select color and luster pure, nuisanceless hawthorn of uniform size, and cleaning up;

(2), preliminary treatment: the hawthorn pickling of going ahead of the rest is handled, hawthorn is 1:2 to 1:3 with the ratio of water, and 20 ℃-30 ℃ of water temperatures are handled hawthorn 20-25min with the hydrochloric acid solution of 0.2-0.4%, feel like jelly and be loose shape when being dipped into pericarp, water is the milkiness shape can drain hawthorn, does not end to muddy with the flowing water rinsing, carries out alkali lye then and handles, working concentration is 0.4%, water temperature is soaked 2-5min at 20-29 ℃, and processing finishes, and cleans alkali lye with clear water immediately;

(3), stoning: the fruit stone of the back hawthorn that will neutralize cuts out, and cleans up;

(4), boil: put into clear water in the pot and boil, more above-mentioned pulp is put into pot and boil, the water yield can there be hawthorn, adds rock sugar at last and boils 4-6min, obtains pulp and syrup mixture, and water and rock sugar ratio are 4.5:1 to 5.5:1;

(5), preparation soup stock: select high-quality pawpaw stoning peeling pelletizing for use, clear water candy rolling on the rocks, put into the pawpaw grain then, add fresh milk, Coconut Juice again, pawpaw, fresh milk and Coconut Juice ratio are: 1:1.5:1.5, use smothered with 25-35min, the soup stock that obtains mixes with syrup mixture 1:1 with the middle pulp of step (4);

(6), seal: the can of batching after with soup sealed under the condition of vacuum 0.05-0.08mpa;

(7), sterilization cooling: the can after sealing adopts sterilization in open kettle, sterilizing time 20-30min, sterilization temperature 90-98 ℃, the can after the sterilization moves in the cold water and cools off;

(8), packing: will beat inspection, decals on the can, and with its packing.

Preferably, water and rock sugar ratio are 5:1 in the step (4).

Preferably, step (6) is carried out under the condition of vacuum 0.06mpa.

The invention has the beneficial effects as follows: the hawthorn pickling of going ahead of the rest is handled, hawthorn is 1:2 to 1:3 with the ratio of water, 20 ℃-30 ℃ of water temperatures, hydrochloric acid solution with 0.2-0.4% is handled hawthorn 20-25min, feel like jelly and be loose shape when being dipped into pericarp, water is the milkiness shape can drain hawthorn, ends to muddy with the flowing water rinsing, carrying out alkali lye then handles, working concentration is 0.4%, and water temperature is soaked 2-5min at 20-29 ℃, and processing finishes, clean alkali lye with clear water immediately, above-mentioned steps can be saved the man power and material, shortens the cycle of whole technology, improves output, make that the hawthorn peeling is neat, efficient obviously improves; Because hawthorn is acid relatively, the rock sugar amount will suitably can hide tart flavour again can be too not greasy, and water is difficult for putting many, put less, the density mouthfeel of assurance syrup more, so water and rock sugar ratio are 4.5:1 to 5.5:1; Select fresh milk, Coconut Juice and pawpaw mouthfeel uniqueness in the soup stock for use, fresh milk and pawpaw have dual whitening effect, and normal edible can make skin smooth, and the adding of Coconut Juice makes mouthfeel more soft.
