Selected nutrients and antinutrients in peanut cultivars harvested in Brazil

Abstract

BACKGROUND: There are more than 30 peanut cultivars registered in Brazil. However, there are no published data about the content of nutrients and antinutrients even in the most commercially important ones. Therefore, our objective was to characterize commercial peanut cultivars harvested in Brazil by determining proximate and fatty acid composition and content of selected minerals and phytates, saponins and condensed tannins. RESULTS: Significant variations were found among the cultivars for almost all studied nutrients, except Mg. Granoleico and IAC 505 were identified as high oleic. Results were compared with data from the Brazilian Food Composition Table (TACO) and, for this, percentage differences (D%) were calculated. Appreciable D% were found for proteins, lipids, ash, dietary fiber, almost all fatty acids (except 20:0) and almost all studied minerals (except zinc). Moreover, remarkable variations in content of antinutrients were observed. IAC Red Tatu had the highest content of saponins; IAC OL3 and IAC 886 had the highest amounts of phytates; and IAC 886 had the highest amounts of condensed tannins. CONCLUSION: Results confirm the relevance of differentiating cultivars in the market and in national food composition tables and databases. Furthermore, some of these cultivars may be indicated for new use trends.

Climate risk to peanut cultivation in Brazil across different planting seasons

“…Peanuts are one of the most used crops in crop rotation with sugarcane 4–7 as a result of their potential with respect to rotation systems and low soil fertility requirements; furthermore, they have a well‐developed root system and good adaptation to sandy soils 8 . Peanuts have a high economic value because of their nutritional content, mainly proteins and fats 9,10 …”

Bioactive compounds of peanut skin in prevention and adjunctive treatment of chronic non-communicable diseases

“…Lozano et al , 39 characterized 30 commercial cultivars of peanuts harvested in Brazil about the composition of nutrients and the so-called anti-nutrients, such as phytates, saponins and condensed tannins, finding relevant differences in proximate composition. The identification of nutritional compounds of peanuts according to their cultivars is an important factor in the context of food security, considering that peanuts have high nutritional value, centesimal composition quite relevant to the food industry, low cost when compared to other almonds and are also easily cultivated and economically viable.…”

“…46 According to Arya et al, 30 the lipid composition can contain about 50% of monounsaturated fatty acids (MUFA), 33% of polyunsaturated fatty acids (PUFA) and 14% of saturated fatty acids. For Lozano et al, 39 Brazilian cultivars (high oleic) can provide valuable food sources of oleic acid, which can reach 80% of the total lipid content. 7 As for carbohydrate content, peanuts contain sucrose, starch and reducing sugars in low proportion.…”

Optimizing Procedures for Antioxidant Phenolics Extraction from Skin and Kernel of Peanuts with Contrasting Levels of Drought Tolerance

“…Peanut (Arachis hypogaea L.) is an affordable legume known for its nutritional value, mainly due to the high contents of protein, unsaturated fatty acids, and minerals [1]. Additionally, peanut has been widely recognized for its high content of phenolic compounds with antioxidant activity, which are concentrated in the seed skins and are related to health effects in the human body [2][3][4].…”
