Potensi Spaghettini Komposit Semolina Durum-Pati Ganyong dalam Pembentukan Short Chain Fatty Acid dan Asam Laktat pada Fermentasi Menggunakan Mikroflora Feses Manusia

摘要

Nowadays people have started considering the health beneficial value in selecting food. Government\u27s demand for utilization of local food and food diversification is also increasing. Considering those reasons, the objective of this study was to create a way of food diversification using local ingredient which has physiological benefits for human health. Resistant starch can improve human colonic health through fermentation by colonic microflora to produce Short Chain Fatty Acid (SCFA) and lactic acid. This research was conducted by combining canna starch with semolina durum into a composite flour for spaghettini production. Various type of canna tuber and canna starch proportion were used in the composite flour. Semolina durum contained higher resistant starch (20%) than red canna starch (17.7%) and green canna starch (15.4%). Combination of durum and red canna starch-based spaghettini produced higher amount of resistant starch, SCFA, and lactic acid than combination of durum and green canna starch- based spaghettini. Durumcanna based spaghettini had the ability to produce SCFA and lactic acid during in vitro fermentation using human colonic microflora although the concentration was lower than those of only durum spaghettini.
