Problems solved by technology

At present, there are a large number of chemical compounds, which are often used in food rashly. The relevant departments lack effective means of prior monitoring, because the results obtained by chemical analysis or physical methods are often lagging behind, and there is no effective means of prior monitoring. Means and preventive methods are major defects in the current conventional methods

Embodiment 1

[0039] Example 1 Detection of comprehensive toxicity of fresh milk

[0040] In this example, the comprehensive toxicity of three brands of three kinds of fresh milk was sequentially detected, and the three kinds of fresh milk were: 1. Bright milk without antibiotics, 2. Mengniu pure fresh milk, and 3. Yili pure fresh milk.

[0041] 1. Detection of comprehensive toxicity of antibiotic-free bright milk

[0042] In the second step, the fresh milk sample is bright milk without antibiotics, and bright milk without antibiotics is used as the control; in the third step, the calculated relative luminous intensity is 112%, check Table 1, and the comprehensive toxicity of the tested bright milk without antibiotics :Safety.

[0043] 2. Detect the comprehensive toxicity of Mengniu pure fresh milk

[0044] In the second step, the fresh milk sample is Mengniu pure fresh milk, and bright milk without antibiotics is selected as the control; in the third step, the calculated relative luminou...

Embodiment 2

[0047] Example 2 Detection of comprehensive toxicity of fresh pork

[0048] This embodiment detects the comprehensive toxicity of five kinds of fresh pork of three grades successively, and five kinds of fresh pork are respectively: 1, the fresh pork of national quality system certification, 2, assured pork 1, 3, assured pork 2, 4, from agricultural trade Common pork 1 purchased from the market, and common pork 2 purchased from a farmer’s market.

[0049] 1. Detect the comprehensive toxicity of fresh pork certified by the national quality system

[0050] In the second step, the fresh meat sample is fresh pork certified by the national quality system, and the fresh pork certified by the national quality system is selected for comparison; in the third step, the calculated relative luminous intensity is 99%. Integrative Toxicity of Quality System Certified Fresh Pork: Safe.

[0051] 2. Detection of the comprehensive toxicity of Anxin Pork 1

[0052] In the second step, the fres...

Embodiment 3

[0059] Example 3 Detection of comprehensive toxicity of fresh beef

[0060] In this embodiment, the comprehensive toxicity of two grades of three kinds of fresh beef is sequentially tested. The three kinds of fresh beef are respectively: 1. Fresh beef certified by the national quality system, 2. Common beef 1, and 3. Common beef 2.

[0061] 1. Detect the comprehensive toxicity of fresh beef certified by the national quality system

[0062] In the second step, the fresh meat sample is fresh beef certified by the national quality system, and the fresh beef certified by the national quality system is selected for comparison; in the third step, the calculated relative luminous intensity is 109%. Comprehensive toxicity of beef 1: Safe.

[0063] 2. Detection of comprehensive toxicity of common beef 1

[0064] In the second step, the fresh meat sample is ordinary beef 1, and the fresh beef certified by the national quality system is selected for comparison; in the third step, the c...

Abstract

The invention provides a method of detecting comprehensive toxicity of fresh meat and milk, belonging to food safety and environmental protection technical fields. On given conditions, the luminous bacteria's luminous intensity changes with the outside world's content of poison. The detection of comprehensive toxicity of the fresh meat and milk includes three steps: luminous bacteria preparations, testing sample preparation, the luminous bacteria detection. The freluminous bacteria is freshwater luminous bacteria - Qinghai Vibrio Q67 strain together. The fresh meat leaching fluid samples or fresh milk is mixed with Qinghai bacterium Vibrio Q67 Strain together. Through the detection of the Qinghai Vibrio Q67 strains luminous intensity the comprehensive toxicity of all toxicology together can be determined, then to measure if the food is safe to eat. It is quick, sample to detect comprehensive toxicity, and have high detection sensitivity and broad scope.

Description

technical field [0001] The invention relates to a method for detecting comprehensive toxicity of fresh meat and fresh milk food, and belongs to the technical field of food safety and environmental protection. Background technique [0002] Food safety cannot be ignored. The food safety of fresh meat and milk supplied in the market is currently tested according to the standards stipulated by the state. The detection items include antibiotic residues, heavy metal content, food additives, etc. The methods used are all chemical analysis methods. The detection time is long, the operation is complicated, and expensive equipment is required. Therefore, not only the detection cost is high and the time is long, but also it is impossible to quickly judge whether the sample has acute biological toxicity, especially The total combined toxicity of all potentially biotoxic substances present in the sample could not be determined. For example, the national standard stipulates the detectio...
