A STUDY ON VARIATIONS IN THE RESISTANT STARCH CONTENT IN BANANA (Musa paradisiaca var. awak) CULTIVATED IN U MINH THUONG DISTRICT, KIEN GIANG PROVINCE

Abstract

This study was conducted to determine the variation in resistant starch content during the growth stages of banana (Musa paradisiaca var. awak) cultivated in U Minh Thuong district, Kien Giang province. The goal is to determine the optimal harvesting period for producing starch with a high resistant starch content for food production. The results showed that the resistant starch content in banana grown in U Minh Thượng district varies with growth stages, reaching its highest level was 62.56 ± 1.17 (g/100 g) in the 15^th week (calculated from the onset of inflorescence emergence). The highest starch extraction yield at the 15^th week was 17.12 ± 0.3%. Additionally, some physicochemical properties of banana starch, including swelling power, solubility, water absorption and oil absorption capacity were analyzed.
