Functional Properties of Sago Grub Protein Concentrates With Different Initial Drying Methods

The objective of this study was to determine the effects of various initial drying methods on the functional properties of sago grub protein concentrates and characterize their functional properties. In this work, a block randomized design was employed to extract sago grub protein concentration using cabinet dryer, sun, and oven drying methods. The variables observed were the foaming capacity, foaming stability, water holding capacity, and fat absorption capacity of the protein concentrate. Results showed that different initial drying methods of sago grub did not affect the foaming capacity, foaming stability, or fat absorption capacity of the resulting protein concentrates. In contrast, the water holding capacity of the protein concentrates was significantly affected by different initial drying methods on sago grub. Various initial drying methods resulted in the protein concentrates having a foaming capacity of 7.5–12.5%, a foaming stability of 3.5-7.5%, a water holding capacity of 1.9–2.35 mL/g, and a fat absorption capacity of 299.12–306.75%

Listeria monocytogenes: A CONSIDERABLE PATHOGENIC MICROORGANISM OF CONCERN IN MINIMALLY PROCESSED FRUITS AND VEGETABLES

Effect of Concentration of Moringa Leaf Extract (Moringa oleifera) on the Characteristics of Steamed Pumpkin (Cucirbita moschata) Sponge Cake

Steamed sponge cake is one of the foods made from wheat flour, which until now has been imported. The use of wheatflour in steamed sponge cakes can be reduced by using local foods such as pumpkin and moringa leaves, which also add nutrition al value to steamed sponge cakes. The purpose of this study was to determine the concentration of Moringa leaf extract that is right for producing pumpkin steamed sponge cake with the best characteristics. This study used CRD, which consisted of one factor, namely the concentration of Moringa leaf extract, with 5 levels of treatment as follows: K0 = 0%, K1 = 25%, K2 = 50%, K3 = 75%, and K4 = 100%. The results showed that K2 treatment (50% moringa leaf extract) can produce the best pumpkin steamed sponge cake. Based on its physicochemical characteristics, the addition of 50% moringa leaf extract resulted in a steamed sponge cake with a moisture content of 43.76%, an ash content of 0.30%, a protein content of 7.42%, a fat content of 2.70%, a carbohydrate content of 45.80%, and a specific volume of 2.31 mL/g. Based on its sensory characteristics, steamed pumpkin sponge cake with 50% moringa leaf extract was liked (3.6) forits slight green color (3.1), liked (3.8) forits slight moringa taste (3.2), liked (4.0) forits soft texture (3.9), liked (3.5) forits slight moringa aroma (2.9), and liked (3.7) on its overall characteristics
