Peels of vegetables and fruits are considered waste products and thrown into the environment. However some researches on the peels of fruits revealed the presence of important phytochemicals having diverse biological activities. In the current study peel samples of seven underground vegetables namely Beta vulgaris Brassica rapa Daucus carota Ipomoea batatas Raphanus sativus Solanum tuberosum and Zingiber officinale were evaluated for vitamin and mineral contents. The vitamin C content of the peels ranged between 43.6 to 122.5 mg/100g while riboflavin thiamin and niacin levels were between 0.3 to 0.8 mg/100g non-detection to 0.4 mg/100g and 0.2 to 1.6 mg/100g respectively. Appreciable amounts of various minerals such as calcium sodium magnesium iron manganese zinc potassium and phosphorus were detected in the peel samples. The overall findings confirmed that peels are rich source of minerals and vitamins and can be utilized as food feed and dietary ingredients after appropriate processing.

Abstract

Peels of vegetables and fruits are considered waste products and thrown into the environment. However some researches on the peels of fruits revealed the presence of important phytochemicals having diverse biological activities. In the current study peel samples of seven underground vegetables namely Beta vulgaris Brassica rapa Daucus carota Ipomoea batatas Raphanus sativus Solanum tuberosum and Zingiber officinale were evaluated for vitamin and mineral contents. The vitamin C content of the peels ranged between 43.6 to 122.5 mg/100g while riboflavin thiamin and niacin levels were between 0.3 to 0.8 mg/100g non-detection to 0.4 mg/100g and 0.2 to 1.6 mg/100g respectively. Appreciable amounts of various minerals such as calcium sodium magnesium iron manganese zinc potassium and phosphorus were detected in the peel samples. The overall findings confirmed that peels are rich source of minerals and vitamins and can be utilized as food feed and dietary ingredients after appropriate processing.
