Introduction

Fungi are one of the important biological factors that cause the deterioration of grain quality. In order to early evaluate and identify fungi and mycotoxins in grain To better understand the pollution hazards of grain storage and reduce the risk of grain quality and safety, it is necessary to study the types and distribution of fungi in grain.

The standard atlas of stored grain fungi, which was established based on the different morphological characteristics of different fungi species under different growth conditions, can be used to accurately identify the fungi.

This provides auxiliary reference for fungal testing in stored grain and improves the accuracy and reliability of fungal identification results.

GB/T 26628 "Standard Atlas of Stored Grain Fungi for Inspection of Grain and Oils" aims to specify the inspection requirements for different species of fungi in stored grains and give The standard atlas and characteristic descriptions of the main fungi in the species are planned to consist of four parts.

— Part 1: Aspergillus spp.

— Part 2: Penicillium spp.

— Part 3: Fusarium spp.

— Part 4: Other common bacterial genera.
