Comparative Study of the Nutritional Properties of 67 Potato Cultivars (Solanum tuberosum L.) Grown in China Using the Nutrient-Rich Foods (NRF11.3) Index

摘要

The overall nutritional properties of tubers from 67 potato cultivars were systematically evaluated in this study by adopting the Nutrient-Rich Foods (NRF11.3) Index Model. The macronutrients including dry matter, crude protein, total dietary fiber, and starch contents were found to be in the range of 14.8-30.5 g/100 g fresh weight, 5.71-12.0, 1.99-3.39, and 56.0-75.5 g/100 g dry weight, respectively. Additionally, the amounts of vitamin C, K and Fe were 22.6-86.6, 1457-3111, and 1.40-5.06 mg/100 g dry weight, respectively. The NRF11.3 index model has a score of 66.4-102 per 100 kcal for male and 70.8-107 per 100 kcal for female over 18 years old. This model was utilized to determine the macrocomponents and micronutrients of diverse potato cultivars and aid in comprehensive nutritional study on potato as a desirable raw material for staple food processing to human nutrition and daily intake.
