EVALUATION OF PROXIMATE AND MINERAL COMPOSITIONS OF FOUR DIFFERENT TYPES OF PEANUT SEED VARIETY IN MYANMAR

Abstract

Peanut (groundnut) is the most important oil seed crop produced by Central Dry Zone in Myanmar. Peanut production and utilization have been important due to its high oil content and nutritive value. The main objective of this study was to evaluate the proximate and mineral compositions of four different types of peanut seed variety (Sinpadethar-11, Spain- 121, Pin Pyant 6 Month and Pin Pyant 4 Month) which were procured from Department of Agricultural Research (DAR), Ministry of Agriculture, Livestock and Irrigation. The proximate parameters were determined by standard method while mineral contents were analyzed by using Flame Atomic Absorption Spectrophotometry (FAAS) with dry ashing method. Peanut samples were examined for moisture, crude protein, crude fat, ash, crude fiber, total carbohydrate contents, thousand seeds weight, calcium and magnesium contents. The proximate composition results were ranged from the moisture (4.37- 5.06 %), ash (2.39-2.62 %), crude oil content (34.60 - 45.75 %), crude protein (22.23 - 26.50 %), crude fiber (6.77 - 8.89 %) and total carbohydrate contents (17.26 - 25.09 %) respectively. While the mineral compositions for peanut sample were (27.25 – 85.74 mg/100g) of calcium and (124.19 - 299.56 mg/100g) of magnesium respectively.
