Title:
DRYING METHOD OF RAW COCOON, SILK PRODUCT AND FOOD PRODUCT
Document Type and Number:
Japanese Patent JP2023122836
Kind Code:
A
Abstract:
To provide a drying method of a raw cocoon capable of achieving mass production of raw silk with little yellow discoloration caused by heat and a soft feeling, and obtaining edible pupae with good taste and flavor.SOLUTION: In the drying method for the raw cocoon, the raw cocoon is placed inside a container 5 maintained at 40°C to 90°C, water molecules contained in the raw cocoon are made to absorb an electromagnetic wave of a near infrared region to accelerate vaporization of the water molecules by resonating with the electromagnetic wave, and the generated water vapor is discharged out of the container 5. Accordingly, a drying ratio is decreased to 45% or less within 24 hours, and a color difference between the two, calculated as an Euclidean distance in a CIELAB coordinate by measuring a color of a surface of the raw cocoon and the surface of a dried cocoon, is made smaller than 2.3 which is a just noticeable difference.SELECTED DRAWING: Figure 1
