Abstract

The purpose of this research was to observe antioxidant activity of lotus leaves extract (Nelumbo nucifera). The extraction  process was carried out using three different solvents namely methanol, ethyl acetate and n-hexane. The observed parameters were extraction yields phytochemical compounds (alkaloid, flavonoid and tanin) and antioxidant activity using DPPH method. The results showed that the methanol extract exhibited the highest yield with a value of 0.708% and had a flavonoid tannin content of 1161 ppm. The antoxidant activity of the same extract as indicated by IC50 value was 199 ppm. The extract ethyl acetate and n-hexane solvents did not show potential antioxidant activities

Abstract

The purpose of this research was to know the physicochemical and sensory characteristics of dry noodle with minnow carp (Thynnichthys thynnoides) fish meal addition. This research used the factorial randomized block design. The treatment was different fish meal concentration (0, 5, 10, 15, and 20%). The parameters of this research were chemical variables (water, ash, lipid, protein, carbohydrate, calcium, phosphorus content), physical variables (lightness, chroma and hue, hardness, tensile strength, elongation, water absorption) and sensoric variables (colour, aroma, taste and texture). The result showed that treatment gave signitificant effect on physical variables (water, ash, lipid, protein, calcium and phosphorus content), physic variables (lightness, chroma and hue, hardness, tensile strength, elongation) and sensoric variables (colour, aroma, taste texture), but there was no significant effect on carbohydrate content and water absorption. The best treatment was addition of M1 (100% wheat flour and 5% minnows carp fish meal). The concentration of water, ash, protein, lipid, carbohydrate, calcium, and phosphorus were 13.03%, 14.21%, 23.75%, 0.9%, 46.75%, 0.127%, 0.162%, respectively. The lightness, chroma, hue, hardness, tensile strength, elongation and water absorption were 58.4%, 18.6%, 71.1o, 1011.73 gF, 15.93 gF, 27.33%, 140.98%, respectively. Panelist scores for colour, aroma, taste and texture were 3.8 (rather bright yellow), 4 (not fishy), 4.08 (tastefull) and 4.08 (chewy), respectively

Abstract

The purpose of this research was to obtain edible film that meet physical and chemical characterictics of Japan Internasional Standard (JIS). This research was conducted from June 2015 to December 2015. This research used the randomized bloc design with one factor, the addition of eel surimi waste water (0 mL, 12 mL, 15 mL dan 18 mL). The observed parameters included chemical (water activity) and physical (thickness, percent of elongation, vapor transmission rate) characterictics. The results showed that there were no significant effects on thickness water activity, vapor transmission rate and percent of elongation. Furthermore, the edible film met Japan Industrial standard (JIS) based on thickness 0.139 to 0.214 mm, vapor transmission rate 3.514 to 7.133 g/m2/jam and the percent of elongation 106.22% to 174.55%.
