Does freezing affect vitamins?
Some Vitamins Are Lost During Processing of Frozen Produce Generally speaking, freezing helps retain the nutrient content of fruits and vegetables. However, some nutrients begin to break down when frozen produce is stored for more than a year ( 2 ). Certain nutrients are also lost during the blanching process.
Can freezing cause vitamin losses?
Despite the effectiveness of freezing as a preservation method, there is evidence that pre-freezing procedures and prolonged storage can reduce the concentration of vitamins present within certain vegetables.
Does freezing destroy vitamins and minerals?
As long as the food was grown in a high-quality way (for example, organically grown) and was fairly fresh at the time of freezing, the overall nutrient retention in a frozen food can be quite high. In other words, many of the vitamins and minerals will keep fairly well in frozen foods.
Does freezing destroy vitamin B12?
Sterilization is carried out by brief heating to kill bacteria. At this stage, some loss of vitamins such as C, B2, B12 is inevitable. However, fruits and vegetables maintain most of their nutritional value. In a frozen state they do not oxidize, so their nutrients cannot be damaged during lengthy transportation.
