Process for processing canned cubilose through cooperation between microwaves and vacuum pretreatment

Abstract

The invention discloses a process for processing canned cubilose through cooperation between microwaves and vacuum pretreatment. The process comprises the following steps: putting a raw cubilose material into a can bottle, putting the can bottle in a microwave vacuum sterilization chamber, setting a vacuum degree to be -0.08 to -0.1 MPa, microwave intensity to be about 20 W / g and a temperature to be 105-115 DEG C, performing microwave vacuum sterilization treatment on the raw cubilose material for 12-15 minutes, conducting filling of sugar liquid after treatment, and performing sterilizing for 5-10 minutes through saturated steam with a temperature of 121 DEG C. Thus, the shelf life of the canned cubilose is kept at 6-12 months. According to the process, the effect which cannot be achieved by sterilization under a single microwave or single vacuum condition is achieved through cooperation between microwaves and vacuum sterilization pretreatment; the damage of microwave vacuum pretreatment and traditional thermal sterilization to the quality of the canned cubilose is far less than the damage of traditional thermal cansterilization to food materials; and the process greatly protects product quality and is suitable for further popularization and application.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a process for processing canned bird's nest with microwave and vacuum pretreatment. Background technique [0002] The bird's nest is a nest built by mixing and bonding the saliva secreted by several swiftlets of the swift family Swiftlet family and their down feathers. It is mainly produced in Southeast Asian countries such as Malaysia, Indonesia, Thailand and Myanmar, as well as the coastal areas of Fujian and Guangdong in my country. Bird's nest is rich in sugars, organic acids, free amino acids and characteristic substances - sialic acid. [0003] The bird's nest needs to be sterilized during the filling process. The existing commonly used sterilization and sterilization methods mainly include microwave sterilization, high temperature water circulation sterilization and steam and compressed air mixed circulation gas sterilization; the above sterilization methods are a...

AI Technical Summary

Problems solved by technology

[0003] The bird's nest needs to be sterilized during the filling process. The existing commonly used sterilization and sterilization methods mainly include microwave sterilization, high temperature water circulation sterilization and steam and compressed air mixed circulation gas sterilization; the above sterilization methods are all There are disadvantages, such as microwave sterilization of materials, which can only kill general microorganisms, and the sterilization effect on canned indicator bacteria Geobacillus stearothermophilus is small; the high-temperature water circulation sterilization method is to heat the packaged food to 121 °C Sterilization, sterilization, its disadvantages are: the nutritional content of food is greatly damaged and lost at 121 °C, and the texture properties of canned food have a large change at a high temperature for a long time, and it also consumes a large amount of The heat energy; the steam and compressed air mixed circulation gas sterilization method is to heat the packaged food to 121°C through a hot-ventilated steam sterilizer for sterilization. The disadvantages are: when the circulation is not sufficient, there will be dead ends for sterilization, and the requirements for placing items are relatively high. Strict, and at 121 ℃, the nutritional content of food is greatly damaged and lost, and the texture characteristics of canned food have a large change; at the same time, it consumes a lot of heat energy

[0004] When the existing commonly used sterilization and sterilization methods are used to sterilize canned bird's nest, the sterilization effect is poor, and the nutritional components in the bird's nest are easily damaged and lost.
