Abstract

The invention discloses a kind of sterilization and preservation method of extreme high static pressure to fresh-cut carrots.By carrot, vacuum is pre-packaged in quantitative mixture of ice and water, using 700 1200MPa pressure conditions and specific sterilizing time, specific boosting, decompression rate obtains that the fresh-cut carrots of shelf life preservation can be expected.The method of the present invention, can extend fresh-cut carrots shelf life, and peroxidase in carrot well, pectinesterase, polygalacturonase is passivated, and largely make it that pectin is not destroyed in carrot cell wall, so as to maintain the quality of carrot.This method process for sterilizing is simple, and maintains the nutritive value and quality of carrot well, is that the sterilization and preservation of fresh-cut fruit and vegetable opens new direction.

Description

A kind of sterilization and preservation method of extreme high static pressure to fresh-cut carrots
Technical field
The invention belongs to food processing preservation technology field, and in particular to a kind of extreme high static pressure is killed to fresh-cut carrots Bacterium method for preserving.
Background technology
Carrot (Daucus carota L.) fleshy root also contains containing abundant vitamin, starch, glucose, sucrose The trace quantity mineral substance elements such as calcium, fluorine, iron, cobalt, phosphorus, manganese, cobalt.And its fat, protein, phosphorus, calcium, vitamin C, carrotene etc. Content is higher by much than other vegetables, is the vegetables of great nutritive value.But fresh carrot is difficult preservation, current fruits and vegetables Storage technology, such as:Drying, hot-working etc., although extend fruits and vegetables preservation term, but it is most with violent hot-working Mode, could kill harmful microorganism and malignant bacteria, to ensure product safety, quality of such heat treatment meeting to carrot Very big destruction is caused with nutritional ingredient, and considerably increases the financial cost of preservation.
Superhigh pressure technique can reduce manufacturing procedure energy again as the technology being most widely used in non-thermal technology with maturation Ensure that in storage period the quality problems such as corruption, brown stain, dehydration, peculiar smell and softening do not occur for product, malignant bacteria can killed The nutritional ingredient and texture quality of fruits and vegetables are kept while with harmful microorganism well.In current research, have and transport respectively Handle the sterilization and preservation technology of different fruit and vegetable foods at different conditions with 100-600MPa pressure, and can be in shelf life Interior notable holding fruits and vegetables quality and cell microstructure.But there is not the report sterilized under higher pressure to fresh-cut carrots.
The content of the invention
It is an object of the invention to provide a kind of sterilization and preservation method of extreme high static pressure to fresh-cut carrots.Profit of the invention With more than 700MPa extreme pressures, under given conditions, fresh-cut carrots are sterilized, quality has been obtained and has kept good, battalion Support the carrot products small and that expected shelf life can be reached of loss.
Sterilization and preservation method of a kind of extreme high static pressure to fresh-cut carrots, it is characterised in that carry out in accordance with the following steps:
(1) after selection fresh carrot is cleaned with running water, peeling chooses middle part and is cut into diameter 2-4cm, a height of 8- 12cm cylinder, is put into packaging bag, adds mixture of ice and water, vacuum packaging;
(2) sterilize:Extreme high static pressure processing is carried out to carrot cylinder using extreme high pressure equipment, from transmission medium, if Constant-pressure condition is 700MPa-1200MPa, and the dwell time is 1-2min, and sets rate of pressure rise to be 10-40MPa/s, release speed Rate is 70-100MPa/s;
(3) preservation:Release at once after pressurize is completed, takes out sample after the completion of release, preset cools down 10- in frozen water 15min, by fruit vegetables storing in 4 DEG C of refrigerator cold-storages after cooling.
Described every bag of addition of mixture of ice and water is 15-25g.
The transmission medium is SA dioctyl ester.
The extreme high pressure unit type is HHP-1700-2, is purchased from packet header Ke Fa high pressure techniques Co., Ltd, the equipment Mainly it is made up of low-pressure system, high-pressure system, sealing system, connection system, intelligence control system.
Compared with prior art, the present invention has the advantages that:The finished product quality that the present invention is obtained and nutrition into Divide and keep good, expected shelf-life is can reach under the conditions of 4 DEG C and product keeps better quality.According to extreme high static pressure to fresh Cut the carrot product bactericidal effect that the sterilization and preservation method of carrot obtains good, fresh-cut carrots shelf life can be extended well, And peroxidase in carrot, pectinesterase, polygalacturonase is passivated, largely so that carrot is thin Pectin is not destroyed in cell wall, so as to maintain the quality of carrot.This method process for sterilizing is simple, and maintains well The nutritive value and quality of carrot, are that the sterilization and preservation of fresh-cut fruit and vegetable opens new direction.
