Problems solved by technology

[0003] At present, the method of using fresh vegetables as storage objects to evaluate the preservation effect has the following disadvantages: one is that it is greatly affected by the harvest season of vegetables, and it is difficult to effectively guarantee the supply of vegetables in non-seasonal seasons; the other is the uniformity and product quality of fresh vegetables. The stability of traits is difficult to guarantee
These shortcomings are likely to cause large experimental errors and poor repeatability, making it difficult to carry out good comparison work between different laboratories

Abstract

The invention belongs to the technical field of preservation performance detection, and particularly relates to a reference sample for preservation effect test, a preparation method and an applicationthereof. The reference sample for preservation effect test comprises a water-absorbing material, wherein a mixed solution of chlorophyll, a humectant and an antioxidant is absorbed in the water-absorbing material. The consistency of the reference sample is good, the reference sample can be widely applied to the evaluation of the preservation effect of a refrigerator and a freezer, the experimental error is small, the repeatability is good, and the good comparison work can be performed among different laboratories.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping performance testing, in particular to a reference sample for fresh-keeping effect testing and a preparation method and application thereof. Background technique [0002] Refrigerators are the first choice for food preservation and preservation in our daily life. In order to meet consumers' demand for freshness preservation, various refrigerator manufacturers are constantly upgrading the freshness preservation ability of the storage space of refrigerators. At present, the evaluation of the fresh-keeping effect of the refrigerator mainly uses fresh vegetables such as spinach to be stored in the refrigerator for a certain period (such as 3 days or 4 days) to detect the moisture, vitamin C, vitamin E, chlorophyll, vitamin B family, folic acid, etc. The change of the index, by analyzing the maintenance of each refrigerator to each index, to evaluate the preservation effect. [0003] At present,...
