Chemical Composition

Vegetables and fruits contain a lot of water, mostly free water, so they evaporate easily. If 5-7% of water is lost, vegetables and fruits will wilt, metabolism will be impaired, and the intensity of hydrolysis and oxidation processes will increase. Low humidity, high ambient temperature, and ...
