PENGARUH LAMA BLANCHING UAP TERHADAP KANDUNGAN KADAR β-KAROTEN, KADAR AIR, DAYA SERAP AIR, DENSITAS KAMBA DAN RENDEMEN TEPUNG UBI JALAR KUNING (Ipomea batatas L.)

Abstract

This study aims to determine the effect of the old steam blanching method on the content of β-carotene content, moisture content, absorbency, cage density and yield of yellow sweet potato flour (Ipomeabatatasl.). The yellow sweet potato processing technique with long steam blanching has a significant effect on β-carotene content, moisture content, water absorption, kamba density and yield. The highest β-carotene content was found in the 20-minute blaching treatment (1.1695 µg / g), the highest water content of yellow sweet potato flour was found at the treatment level without blanching for 20 minutes (9.66%), water absorption of sweet potato flour the highest yellow was found at the level of blanching treatment with a time of 20 minutes (2.90 g). The highest yield o.
