[0049] Examples 25-28 Tests on cell wall structure and content changes of lotus bean after freezing and thawing at different temperatures

[0050] 15 grams of fresh lotus beans were blanched at 94.5°C for 48 seconds and then frozen in an ISS100 fluidized freezer for 4 minutes. The cooling medium was a mixture of liquid nitrogen and air (volume ratio of liquid nitrogen and air was 1:6). After freezing, use transmission electron microscope to observe the changes of cell wall structure and content. The results are shown in Table 5,
