Should I use baking soda or alkali for washing vegetables

Baking soda or alkali can be used to clean vegetables, but baking soda is more suitable for removing pesticide residues, while alkali is more suitable for neutralizing acidic stains. When choosing, one should consider the type of vegetables, the nature of stains, and personal skin tolerance. When cleaning vegetables, using baking soda can effectively decompose organic phosphorus pesticides. Its weak alkalinity can damage the molecular structure of pesticides. After soaking for 10 minutes, rinse with running water. It is recommended to control the concentration of baking soda solution within 1% -2%, as excessive concentration may damage vegetable epidermal cells. It is particularly suitable for leafy vegetables such as spinach and rapeseed, but it should be noted that vegetables with complex surfaces such as broccoli need to be gently brushed.

Alkali has a more significant cleaning effect on oily stains and acidic soil residues, especially suitable for cleaning root vegetables such as potatoes and carrots. Its strong alkalinity can dissolve the wax layer of the epidermis, but may cause the loss of some water-soluble vitamins. When using, the soaking time should be shortened to within 5 minutes to avoid softening of the vegetable texture. It is recommended for individuals with sensitive skin to wear gloves during operation to prevent irritation from alkaline substances.

Regardless of whether baking soda or alkali noodles are used, they should be rinsed repeatedly with running water at least 3 times after cleaning. It is recommended to prioritize using baking soda for leafy vegetables, and alternate between using two types of cleaning agents for root vegetables. Daily cleaning can be combined with food grade detergent to assist in stain removal, but a phosphate free formula must be selected. Before storing vegetables, ensure that the surface is completely dry to avoid secondary contamination. For special groups such as infants and young children, it is recommended to use salt water immersion combined with ultrasonic cleaning machine for processing.
