Abstract:
The purposed of this research is to study the optimum conditions of wet separation of mucilage from hairy basil seed that effected by of different temperatures (55, 60 and 65 oC) and soaking time (30 60 and 90 minute, was investigated). The experimental design was 32 Factorial in CRD. The results found that increasing both water temperatures and time increased moisture content and water activity of mucilage powder of hairy basil seeds, in the range of 4.3-5.0 % and 0.42-0.6, respectively. Furthermore, the percentage of mucilage powder (% yield) was significantly different (P≤0.05) . At the lowest soaking temperature (55 oC), the yield percentage was higher than that soaked at high temperature (60 and 65 oC). It also found that soaking time (30 60 and 90 minutes) showed in not significant difference (P > 0.05) on the yield of mucilage powder. The optimum condition for producing of mucilage powder was water soaking at 55 ° C for 60 min. with yield and crude fiber of 36.03 % and 0.48 %, respectively.The mucilage powder have the chemical composition on moisture, fat, protein, ash and crude fiber were 0.45, 3.57, 9.65, 4.96 and 0.48 %, respectively. The optimum concentration of potential enrichment of in Mao juice was investigated by the considering the amount of bioactive compounds with antioxidant capacity and consumer acceptability that must be not significant different (P > 0.05) from control. This study demonstrated that the optimum level of mucilage powder to enrichment fiber of Mao juice product was 0.1%. The 100 g of Mao Juice product with dietary fiber supplemented using mucilage powder from hairy basil seed showed the amount of anthocyanin, phenolic, and ascorbic acid for 9.67 mg cyaniding 3-glucoside, 215.30 mg GAE/100g and 541.60 mg/100g respectively. Furthermore showed the antioxidants activities of DPPH๐ and FRAP were 286.77 and 168.00 mg Trolox/L respectively.
