What kind of apple is this?

There are sandy apples and soft apples in all varieties of fruits. The crispness and sandiness of apples are caused by the differences in the content and properties of insoluble pectin and cellulose in the pulp cells of apples during the ripening period. After the apples mature, due to the effect of ethylene, the insoluble pectin content between pulp cells decreases, the soluble pectin content increases, the fiber content decreases, and the adhesion between cells decreases. The flesh gradually softens (i.e. becomes soft) from being hard and crisp when immature. During the ripening period, the degree of adhesion between cells is moderate, so it will not be as hard as when it is immature, nor will it be as "soft" as when it is about to go bad. However, due to different apple varieties, the degree and rate of decrease in intercellular adhesion are different, resulting in differences in crispness and softness among apples.
