Abstract
The cooling system controlled by the freshness estimate function to freshly store foods,was examined. To drive the freshness estimate expression,an experiment on storage of tuna was made and the following results were obtained.
1) Ratio of weight to initial weight,yield,was greatly influenced by conditions of humidity and velocity of air.
2) K value was not influenced by conditions of air velocity under 95-75% humidity and 0 -1m/s air velocity.
3) Change of color was influenced by conditions of humidity and velocity of air.
So using weight of evaporated water in tuna as a function,relative expression of humidity and velocity of air for saving weight loss of tuna was induced.
