MODIFIKASI PATI HANJELI (Coix lacryma-jobi L.) BERPORI MELALUI ULTRASONIKASI DAN OZONASI

<p>Adlay (Coix lacryma-jobi L.) is a potential source of starch but has not been utilized optimally. Native adlay starch has several weaknesses such as functional properties of low swelling volume and solubility, prone to retrogradation, and low stability. Physical modification of ultrasonication and chemical modification by oxidation using ozone can be an alternative to improve the functional properties of adlay starch through the formation of porous starch. The aim of this research was to produce porous adlay starch by ultrasonication and ozonation. The study consisted of several different treatments on hanjeli starch (ozonation starch, ultrasonication of 15 minutes, ultrasonication of 30 minutes, combined ultrasonication of 15 minutes and 30 minutes with ozonation). The results showed the appearance of pores on the surface of the granules of modified adlay starch with the best results being modified combination of ultrasonication 30 minutes and ozonation, which resulted in a decrease in swelling volume from 18.13 ± 3.98 mL/g to 15.71 ± 0.35 mL/g, an increase in solubility from 6.76 ± 0.62% to 9.59 ± 0.44%, and a decrease in water absorption capacity from 1.25 ± 0.02 g/g to 1.13 ± 0.02 g/ g. Modification of adlay starch by ultrasonication, ozonation, and their combination effectively produced porous starch granules, but did not cause the formation of new functional groups in starch.</p>

<p>The average consumption of dietary fiber in Indonesian is still below the recommended daily intake. Low dietary fiber intake has an impact on the development of degenerative diseases and metabolic syndrome. One of the risk factors for the occurrence of the disease is oxidative stress. The most effective strategy to overcome oxidative stress is through dietary antioxidants intake. Cowpea is proven to be rich in bioactive compounds such as flavonoids, dietary fiber as well as antioxidants, and these compounds have been successfully increased by germination. This study aims to develop cowpea sprouts flour as a functional cereal high in dietary fiber and antioxidants. The cereal was prepared by the best formula based on two steps of sensory analysis. The first one, the sensory analysis conducted to select the formula based on the best sensory quality of the cereal made by the various proportions of cowpea flour (%b/b) (80, 85, 90, 95, 100). The selected formula was further used to prepare the cereal with different flavoring agents (5% b/b) (ginger, cinnamon, and ginger-cinnamon) to find the best formula based on the preference level. The cereals were further analyzed to determine the sensory quality compared to the commercial cereal, the dietary fiber content which includes the total, soluble, and insoluble dietary fibers, as well as the antioxidant potential with the total phenolic content (TPC) evaluation. Formula with 80%(b/b) cowpea flour and 5% (b/b) ginger as flavoring agents produce cereal with the highest preference level and stated as the best formula. The cowpea sprouts cereal exhibited a significantly higher quality of aroma, texture, and overall than the commercial ones. The cereal also showed the highest levels of total, soluble and insoluble dietary fiber as well as the TPC. These results have significant implications on the development of functional cereal using locally legumes sprouts flour.</p>
