Abstract

A kind of processing method of peach juice beverage is that the bright peach of selecting, clean is partly dug nuclear through splitting, softening, the broken squeezing of precooking, filtration, allotment, the degassing and homogeneous, adds operation such as hot-filling bottle, sealing and sterilization and make bottle (jar) and adorn natural peach juice beverage.Add beta carotene and Vc on the technology, prevented the variable color and the oxidation of product, improved its stability, kept the color of bright peach, increased the nutritional labeling of needed by human body.

Description

A kind of processing method of peach juice beverage

What the present invention relates to is the production and processing method of fruit drink in the food processing.

Fruit drink can be divided into three types substantially: clarification type.Muddy type and band fruit pulp type.On the market, carbonated fruit beverage, fruit Normal juice and orange granule juice, fruity sauces all are these common a few class beverages.Peach is the large tonnage product in the fruit, but is difficult for preserving, and processing method commonly used at present is to make can, honey dew beverage (as sauce).As the CN1055646A(application number: the method for the processing peach sauce that 90102084.2) is provided, be that peach meat in peeling, after killing enzyme is pulled an oar, pulverized and becomes the peach pulp that fineness is 0.01～1mm, add syrup, citric acid water, again through exhaust, sterilization peach sauce.Further dilute with water can become peach juice beverage.Present muddy type Normal juice peach drink variety is less.

The objective of the invention is to utilize bright peach to make and to keep peach meat true qualities, original flavor, muddy type beverage with suitable high nutritive value.

The technological process of processing method provided by the present invention as shown in drawings.Check and accept, select in fruit and the cleaning process in bright peach, choose fresh, the ripe appropriateness of fruit, local flavor is normal, anosis, the fruit of worm and damage, cleans back NaOH solution with 0.02～0.05% under 50～70 ℃ and embathes 5～10min to remove the peach hair, cleans it with clear water again.Splitting half, digging the nuclear operation is peach is rived and to cut out fruit stone, then places 1.5～2.0% saline solution to protect look immediately.Precooking softening is peach meat to be put into boiling water precook and make it softening, adds 0.2～0.5% citric acid simultaneously preventing the pulp variable color, and the time of precooking is that to grasp pulp soft and do not have the heart of giving birth in mashed and the pulp and decide.Reach to pull out after the requirement and put into circulating water and be cooled to below 35 ℃.Adopt fruit crusher with pulp crushing, execute juice extractor with spiral shell then and squeeze the juice, filter through scraper plate filter, fine filter again, finish fragmentation, squeeze and filter operation and obtain peach juice.Allotment is to add syrup in peach juice, citric acid, beta carotene and VC, the soluble solid that transfers to fruit drink is 10～15%, citric acid content is 0.1～0.6%, content beta-carotene 0.2～0.4mg/100ml, VC content are 10～40mg/100ml.The degassing be with fruit juice under 40 ℃, in 93.3KPa(700mmHg) below reduce pressure the degassing 5～15min, in homogenizer, carry out homogeneous then, homogenization pressure is 10～25MPa(100～250kg/cm ²).The fruit juice that homogeneous is good is heated to 85 ℃, bottling (jar) while hot and sealing immediately.Then the juice bottle (jar) of good seal is placed 85～100 ℃ of water normal pressures to keep 5～20min, take out cooling peach juice beverage.

The peach juice beverage that processes has the vivid color of original seed peach, and does not have metachromatism; Beverage also keeps fragrance and the taste of the bright peach of original seed, does not have peculiar smell.General appearance there is no lamination, just is placed with the broken end of a small amount of pulp precipitation for a long time.The physical and chemical index of product is:

Soluble solid (measuring) 10～15% with refractometer

Total acid (with citric acid juice) 0.1～0.6%

Arsenic (in As) mg/kg＜0.5

Plumbous (in Pb) mg/kg＜0.1

Copper (in Cu) mg/kg＜10

The present invention provides a new technology for bright peach processing, and is new varieties of fruit beverage increase.Beta carotene and VC on processing technology, have been added, prevent product variable color and oxidation, improved the stability of product, kept look, the fragrance of former peach well and increased the nutritional labeling of needed by human body, increase its nutritive value, become good drink variety.

Example

Choose into ripe yellow peach, be immersed in after cleaning with clear water and pull out after embathing 5min in 60 ℃, 0.03% NaOH solution, split half stoning, putting into boiling water precooks softening, add 0.2% citric acid simultaneously, the softening time is 5min, pulls out to be cooled to below 35 ℃, through broken, squeezing, mistake leaching juice.Syrup, the citric acid solution of adding 45%, and B-carrotene and VC, transferring to soluble solid is 10%, and citric acid content is 0.2%, and B-carrotene is 0.3mg/100ml, and VC is 20mg/100ml.This material is placed degasser, and 15min outgases under 40 ℃, 93.3KPa condition.By homogeneous in the homogenizer, pressure is 20MPa again.Be heated to 85 ℃ at last, bottling, sealing, sterilization (85～100 ℃ of following 20min), cooling promptly gets bottled peach juice beverage.

Claims

1, a kind of processing method that bright peach is processed into peach juice beverage after selecting really, clean, split partly, digging nuclear.It is characterized by peach meat is softening through precooking, cooling, fragmentation, squeezing, filtration, allotment, the degassing, homogeneous, heating, bottling (jar), sealing, process for sterilizing step and make peach juice beverage.

2, processing method as claimed in claim 1 is characterized by that described to precook softening be to place boiling water to handle peach meat, and adds 0.2～0.5% citric acid simultaneously.

3, processing method as claimed in claim 1, it is characterized by described fragmentation, squeezing, filtration is that softening peach meat carries out coarse crushing, squeeze the juice with juice extractor then, after scraper plate filters, smart filter and peach juice.

4, processing method as claimed in claim 1, it is characterized by described being allocated as and in peach juice, add syrup, citric acid beta carotene and VC, soluble solid in the allotment peach juice is 10～15%, citric acid content is 0.1～0.6%, content beta-carotene is 0.2～0.4mg/100ml, and VC content is 10～40mg/100ml.
