Embodiment Construction

[0019] 1. Experimental method

[0020] 1.1 Food waste

[0021] The raw materials come from the faculty canteen of Shenzhen University. The main materials are kitchen waste at noon, mainly rice, vegetables and soup. When sampling, filter out the moisture in the food waste and put it into a plastic bucket. After being taken back to the laboratory, the samples are initially screened to remove plastic bags, bones and other difficult-to-crunch substances in the raw materials. Then put the rejected samples into a pulverizer to crush, and then fully stir the crushed samples.

[0022] 1.2 Experimental reagents

[0023] Formic acid, acetic acid, lactic acid, citric acid, malic acid, and tartaric acid were purchased from Shanghai Aladdin Biochemical Technology Co., Ltd.

[0024] 1.3 Experimental equipment and materials

[0025] Plastic film sealing machine (Yifei SF-400), Zhejiang Jiangnan Industrial Co., Ltd.; cooking machine (HR2166 / 00), Philips Home Appliances Co., Ltd.; analyti...
