Which nutrient category is most susceptible to loss during processing and storage?

• A. Water-soluble vitamins
• B. Fat-soluble vitamins
• C. Minerals
• D. Amino acids

Answer: (A)

Water-soluble vitamins are most easily lost during processing and storage because they dissolve in water and are sensitive to heat, light, and oxygen. During washing, soaking, milling, or cooking, these vitamins can leach into cooking water and degrade with heat, so the vitamin content of foods drops more quickly than other nutrients. In contrast, minerals are inorganic and relatively stable to heat; fat-soluble vitamins are more resistant to processing and are stored in fat tissue, though some loss can occur with fat removal or oxidation. Amino acids can be impacted by heat, but their losses during typical processing and storage are not as pronounced as those of water-soluble vitamins.
