Evaluation method of kitchen waste feed product safety

Abstract

The invention discloses an evaluation method of kitchen waste feed product safety which belongs to the feed safety evaluation field and is based on a fuzzy mathematic theory. The method is characterized in that firstly, through data analysis, data investigation and expert scoring, a multi-layered three-level evaluation index system is established, based on this, an entropy evaluation method and an analytic hierarchy method are used to determine a weighted value of each level of evaluation indexes; secondly, after dimensionless processing is performed on detection data of a random sample, a trapezoidal membership function is used to determine a degree of membership of a detection value relatively to different safety grades; finally, a three-level fuzzy mathematical model is used to carry out comprehensive evaluation, division is performed according to a safety evaluation grade so that a safety grade of a detection sample is acquired. By using the method of the invention, a safety condition of the kitchen waste feed product can be comprehensively reflected so that quality control and safety management of the product are convenient. The method of the invention is scientific and practical and is an effective feed safety integration evaluation method.

Description

technical field [0001] The invention belongs to the field of feed safety evaluation, in particular to a method for evaluating the safety of food waste feed products. Background technique [0002] After SARS, in order to protect public health and environmental sanitation, my country began to promote the recycling and harmless treatment of kitchen waste. So far, there has been an upsurge in the recycling of kitchen waste in China, and a number of effective demonstration projects have been built. Among them, most of the feed demonstration projects can operate normally. However, as a feed product, its safety is closely related to the health of animals and humans. Therefore, feed / food safety supervision is another important issue facing the development of circular economy, and has become an important factor affecting the application and industrialization of kitchen waste feed. The core issue of promotion. For this reason, it has urgent practical needs and significance to clari...

Problems solved by technology

[0007] The technical problem to be solved by the present invention: For food waste feed products, the traditional risk assessment can only describe various risk indicators through a simple single-factor evaluation of "qualified" or "failed", without considering the fuzziness Therefore, the accuracy and comprehensiveness of the evaluation results are often limited, and it is difficult to form an effective comprehensive evaluation conclusion
