Abstract

Sardinella lemuru is one type of fish with the highest population and the most widely caught fish in Indonesia. The protein content is very high, namely 17.8-20% contains various amino acids including glutamic acid, which can potentially be a smart flavor precursor. The research focuses on enzymatic smart flavor production by examining the effect of concentration and hydrolysis time of calotropin and papain combination on characteristics of the smart flavor produced and determining the best treatment to produce smart flavor. This research used two factors: the concentration of enzyme (3%, 4%, and 6% with a ratio of papain and calotropin of 70%: 30%) and hydrolysis time (1, 2, and 3 hours). The research showed that yield ranged from 50.15-50.69%; brightness 89.72-91.57; water 6.91-9.51%; soluble protein 1.13-1.56 mg/ml; antioxidant activity 48.40-54.47%; emulsion power 0.16-0.18 m2/g, emulsion stability 17.27-24.33 minutes; water holding capacity 83.44-89.27% and effectiveness 1.00 (enzyme 6% and time of hydrolysis 3 hours). The best treatment with effectiveness was Sardinella lemuru smart flavor (6% enzyme and 3 hours hydrolysis) with a yield 50.54%, brightness 89.72, water 6.91%, soluble protein 1.56 mg/ml, antioxidant activity 54.47%, emulsion power and stability 0.18 m2/g and 24.33 minutes, and water holding capacity 89.27%.

Abstract

Antioxidant compounds in food are generally less stable when applied to food, so technology is needed to help antioxidant compounds become more stable during storage, one of which is microencapsulation. The research aims to determine the effect of the wall material ratio and drying methods on the characteristics of Sardinella lemuru smart flavor microcapsules. The experimental design used was a two-factor Complete Random Design (CRD): ratio of wall materials (maltodextrin: Arabic gum) and drying methods (spray drying and freeze drying). The research showed that enzyme activity ranged from 14.81-52.64 U/mL; lightness 95.2-100; yield 4.00-17.19%; water content 2.26-9.15%; antioxidant activity 15.75-31.23%; encapsulation efficiency 69.06-78.47%. Microcapsules with the highest water content, lightness, antioxidant activity, and encapsulation efficiency were at the ratio wall materials (maltodextrin: Arabic gum) of 7:3 by spray drying, 9.15%, 100, 31.23%, and 78.47%. On the other hand, the highest yield (17.19%) was at the ratio wall materials (maltodextrin: Arabic gum) 8:2 by freeze-drying. The morphology of the microcapsules by spray drying is spherical, and freeze drying makes it flaky and sharp.
