preparation example Construction

[0026] The preparation method of the chicken extract described in the examples is as follows: cleaning the chicken skeleton; treating with ultrasonic waves at 440w for 10 minutes after soaking; sterilizing with boiling water for 10 minutes; 8 h; after the bones were removed, the remaining material was treated with a colloid mill; vacuum concentrated to 0.5g / mL; spray-dried to obtain chicken extract powder.

[0027] The preparation method of the filter paper warning card: the chicken extract, sodium chloride, 2,3,5-triphenyl tetrazolium chloride are dissolved in water in proportion to obtain a color enrichment bacteria solution, and a 25cm2 medium-speed qualitative thick The filter paper is soaked in the color enrichment solution for 3-10 seconds, drained, dried at 45-50°C, and stored in a dry place.

[0028] The preparation method of the bacteria liquid package in the freshness safety warning card for storage and transportation of chilled poultry is as follows: activate the Ps...

Embodiment 1

[0032] This embodiment provides a freshness safety warning card for storage and transportation of chilled poultry meat. The indicator bacteria chromogenic enrichment solution is composed of the following components by mass percentage: 7.0 mg chicken extract, 4.5 mg sodium chloride, 0.01 mg TTC . Compound the three substances according to the above proportions, and mix thoroughly to obtain the color enrichment solution of the indicator bacteria, which is adsorbed on a 25cm 2 filter paper.

[0033] The concentration of 1mL is 10 2 The cfu / mL Pseudomonas aeruginosa liquid was airtightly filled in small plastic bags. Packed together with the warning card in an airtight plastic bag.

[0034] When in use, squeeze the bacteria bag inside the package to distribute the bacteria liquid evenly on the warning card, and put it in the outer package of chilled poultry meat.

[0035] During the shelf life of chilled poultry meat (0-4°C, 7 days), when the storage and transportation temper...

Embodiment 2

[0037] This example provides a freshness safety warning card for storage and transportation of chilled poultry meat. The indicator bacteria enrichment solution consists of the following components in mass percentage: 9.0 mg chicken extract, 5.0 mg sodium chloride, and 0.01 mg TTC. Compound the three substances according to the above proportions and mix thoroughly to obtain the indicator bacteria enrichment solution, which is adsorbed on a 25cm 2 filter paper. The inventor compounded the above three substances in a certain proportion, so that the growth rate of Pseudomonas aeruginosa in it was consistent with the growth rate on the surface of poultry meat, and its color reaction could accurately reflect the pathogenicity on the surface of chilled poultry meat. The change of saprophytic microorganisms indirectly shows the freshness and food safety of chilled poultry meat.

[0038] The concentration of 1mL is 10 2 The cfu / mL Pseudomonas aeruginosa liquid was airtightly filled ...

Abstract

The invention belongs to the technical field of online monitoring of safety of agricultural products and food products, and discloses a preparation method and a using method of a chilled fresh poultrystorage and transportation freshness safety warning card. The chilled fresh poultry storage and transportation freshness safety warning card is sealed in a container, and comprises filter paper for absorbing color rendering enrichment broth, and a sealed bacteria solution bag. The color rendering enrichment broth is prepared from a chicken extract, sodium chloride and 2, 3, 5-triphenyl tetrazolium chloride; the bacteria solution bag is filled with 102-103cfu / mL pseudomonas aeruginosa. When the chilled fresh poultry storage and transportation freshness safety warning card is used, the sealed bacteria-containing plastic bag in a packaging bag of the warning card is broken by kneading before chilled fresh poultry enters a finished product warehouse, and the warning card is fully wetted and maintained in a sealed state; the warning card is placed outside a packaging bag of the chilled fresh poultry and is transported together with the chilled fresh poultry. When purchasing the chilled fresh poultry, a consumer observes the color of the warning card so as to judge the freshness of the poultry.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of agricultural products and food safety, and in particular relates to a method for preparing and using a chilled poultry meat storage and transportation freshness safety warning card. Background technique [0002] With the advancement of urbanization and the frequent occurrence of bird flu epidemics, the poultry farmer's market is driven to change from the mode of killing and selling to centralized slaughtering mode, and the sales of live poultry are shifting to fresh or frozen sales. Both at home and abroad are vigorously promoting "centralized poultry slaughtering and fresh poultry meat on the market". After poultry is slaughtered, residual microorganisms on the body surface grow during storage and transportation, thereby accelerating the spoilage of poultry meat. Because consumers cannot judge the freshness and safety of chilled poultry meat by naked eyes, thereby affecting the mark...
