3.4. Effect of different freezing conditions on total calcium content and texture
Calcium processing is popular in the fruits and vegetables industry due to the fact that calcium can not only maintain the shelf life of fresh vegetables and fruits to improve the quality of products, but also can complement the necessary requirements for human body. As can be seen from Table 1, there was no significant (p > 0.05) difference of total calcium content between fresh radish and SF products. During immersion freezing process, the calcium can be absorbed from the liquid coolant into the product.
