Embodiment Construction
[0048] A hyperspectral image technology method for predicting the growth of spoilage fungi, the specific implementation is as follows:
[0049] 1 Materials and methods
[0050] Botrytis cinerea, Rhizopus stolonifer, and Colletotrichum acutatum were provided by the Laboratory of Food Science and Technology College of Nanjing Agricultural University.
[0051] The medium is potato agar medium, which consists of 5g of potato powder, 20g of glucose, 5g of NaCl, 15g of agar, 0.1g of chloramphenicol, 1000mL of water, pH5.8-6.2; the volume of medium contained in each petri dish is 20± 2mL, the medium thickness is 2.5±0.5mm.
[0052] The strain culture method is as follows: prepare 30 sterilized plates, pour 20mL of the same sterilized medium on it, and inoculate the three kinds of fungi by plane streaking after cooling, 10 plates for each type of bacteria, and cultivate them. The thermostat is 25°C and the relative humidity is 85%. After culturing the strains for 5 days, they were is...
