Results from studies that have compared the nutrient content of frozen and fresh produce vary slightly. This is because some studies use freshly harvested produce. Which removes the effects of storage and transport time, while others use produce from supermarkets food.
Additionally, differences in processing and measuring methods can influence results.สมัคร ufabet
However, in general, the evidence suggests that. Freezing can preserve nutrient value, and that the nutritional content of fresh and frozen produce is similar.
When studies do report nutrient decreases in some frozen produce, they are generally small.
Furthermore, levels of vitamin A, carotenoids, vitamin E, minerals and fiber are similar in fresh and frozen produce. They’re generally not affected by blanching.
Studies comparing supermarket produce with varieties. Such as peas, green beans, carrots, spinach and broccoli — found the antioxidant activity and nutrient content to be similar.
Produce is nutritionally similar to fresh produce. When nutrient decreases are reported in frozen produce, they’re generally small.
Frozen produce may contain higher levels of certain nutrients.
This is most commonly seen in studies that compare frozen produce with fresh varieties that have been stored at home for a few days.
For example, peas or spinach may have more vitamin C than supermarket-bought fresh peas or spinach that have been stored at home for several days.
For some fruits, freeze drying resulted in higher vitamin C content, when compared to fresh varieties.
Additionally, one study suggests that the processes undertaken to freeze fresh produce may increase fiber availability by making it more soluble.
