How to Maintain the Quality of Sesame Grey at Low Temperatures

Sesame Grey is prone to quality issues in low temperatures; thus, maintaining its quality requires a specific approach. With winter already here and everything in the world adhering to the principle of "expansion in heat and contraction in cold," sesame grey is particularly susceptible during the cold, damp season. Without proper care, it can lead to freezing and thawing cracks.

Water behaves quite oppositely; when the temperature of the climate falls below 0 degrees Celsius, water freezes and follows the "cold expands, hot contracts" phenomenon, forming an unusually loose structure. If sesame ash absorbs a large amount of water, the water will freeze and expand in volume. At this point, when the ash absorbs enough water, a cycle is formed. When the sesame ash can no longer withstand this tension, it will crack, resulting in economic losses.
