Abstract

The edible film is a protective coating that could be directly applied to food products. This research aims to observe the physical characteristics of whey composite edible film with different plasticizer addition (glycerol, sorbitol, polyethylene glycol). The research was conducted as a laboratory experiment and the observed variables were film thickness, tensile strength, elongation at break, water vapor transmission rate (WVTR), and followed with microstructure observation. The research was conducted in a completely randomized design and analyzed with analysis of variance (ANOVA) followed with the least significant difference (LSD) test. The physical measurement of the edible film showed that the thickness was at 0.0286-0.0308 mm, the tensile strength was at 5.72-8.20 N, the elongation at break was around 28.66-57.5%, and the WVTR was at 7.63-7.96 g/m2.day. Moreover, the microstructure observation showed that the molecules in the edible film were evenly distributed.

Abstract

The objective of this study was to evaluate the effect of different starter cultures on the fermentation of yogurt added with aqueous extract of white oyster mushroom (Pleurotus ostreatus) whether each starter culture respond differently. This study used a completely randomized design (CRD) with 3 treatments and 4 replications. Yogurt was made with one of the starter cultures as treatment: Streptococcus thermophilus (ST), Lactobacillus acidophilus (LA), or Lactobacillus bulgaricus (LB). Data were analyzed using analysis of variance followed by the least significant difference test. The variables tested were pH, total acid content, viscosity and total lactic acid bacteria. The results showed that yogurt made with ST had lower pH and total acid than the others. The use of LB resulted in higher total acid content. The addition of different starter cultures in yogurt did not influence viscosity. Among starter cultures, the use of LA resulted in higher total lactic acid bacteria (LAB) than the others. However, the number of LAB from different treatments were not much different (within the range of 7 log CFU/mL). It is suggested that the three starter cultures are adaptive and capable to fermenting yogurt added with aqueous extract of white oyster mushroom (Pleurotus ostreatus).

Abstract

The research aims to analyse the effect of bromelain enzyme addition from Ananas comucus under different pH condition to the physicochemical properties of cottage cheese. The observed variables include protein, fat, moisture, ash and cheese yield. The research was conducted in a completely randomized design with 4 treatments (K1 = pH 4.5; K2 = pH 4.6; K3 = pH 5.4; and K4 = pH 5.5) and 4 replications. All of the data were analysed with analysis of variance (ANOVA) and followed with least significant difference (LSD) test. The results showed that the bromelain addition under pH 4.6 showed the best physicochemical properties of cottage cheese that had lowest fat content (0.67 ± 0.53 %) and highest yield (18.15 ± 0.22 %) compared to other pH condition, while the protein and ash content did not show any significant difference on all pH condition.

Abstract

The leaf of Dracaena angustifolia has been used widely not only as natural food colorant but also as a natural source of vitamin C. The objective of this study was to obtain the best addition level of Dracaena angustifolia leaves aqueous extract as natural food colorant for milk toffee based on its effect on texture, color, vitamin C and reducing sugar content. Milk toffee was formulated with different addition levels of Dracaena angustifolia leaves aqueous extract as treatment; 3%, 4%, 5%, 6% on weight/milk volume basis, and compared to control (0%). Higher addition level of Dracaena angustifolia leaves aqueous extract to milk toffee resulted in higher (P<0.01) L*, a*, b* values, and softer texture. Vitamin C and reducing sugar content were increased by the addition of 4% extract. However, there were no further differences on vitamin C and reducing sugar content when the addition level was increased up to 6%. Therefore, among treatments, the highest addition level used in this study (6%) is suggested as the best addition level according to texture, color, vitamin C content and reducing sugar content of milk toffee. The addition of natural food colorant, which contains antioxidant, e.g. Dracaena angustifolia leaves aqueous extract, also promotes the diversification of milk toffee.
