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

Chicken meat is a nutritious food that can increase immunity but has perishable food properties that are easily damaged so it is necessary to add preservatives, namely chitosan as an edible coating to protect the meat from microbial contamination. Gourami (Osphronemus goramy) scales have the potential to be processed as chitosan. Through 3 stages, namely deproteination, demineralization, and deacetylation. The purpose of this study was to determine the effect of adding chitosan with gourami fish scales and cloves as an edible coating on the quality of raw chicken meat at room temperature for 9 h. This study used a factorial completely randomized design (3×3), with factor A: concentration of chitosan solution (0%, 1%, and 2%) and factor B: concentration of clove solution (0%, 1%, and 2%) and repeated 3 times. The results showed that the control treatment without clove and chitosan after 9 h of storage at room temperature had a significant difference in effect on the treated samples. The best treatment was found in the interaction of 2% chitosan (K2) and 2% cloves (C2) with microbial contamination of 2×10 5 CFU/g so that it still meets the standards of the National Standardization Agency (BSN) namely, chicken meat has a maximum requirement of 1×106 CFU/g, which can maintain the quality of meat, both in terms of pH, water content, and acceptability of organoleptic values which are still favored by panelists.

Abstract

An experiment aiming for studying chemical aspects of lesser mouse deer meat (Tragulus javanicus). This research explored the chemical aspects of lesser mouse deer meat (Tragulus javanicus). Eight lesser mouse deer (four female and four male) were used in chemical aspects of lesser mouse deer meat. The parameters observed included proximate analysis, amino acid, fatty acid, cholesterol and EPA-DHA of the meat. The results showed that average meat chemical composition were content of water, protein, fat, ash and cholesterol were 76.33 %, 21.42 %, 0.51 %, 1.20% and 50.00 mg/100 g, respectively. Fatty acid consist of lauric acid, miristate, palmitate, stearic, oleic, linoleic, and linolenic were 1.04 % 3.09%, 30.97, 0.77%., 59.41%, 3.22% and 1.12%, respectively. The total EPA and DHA was 0.13% and 0.05%,   Keywords: amino acid, fatty acid, cholesterol and EPA-DHA

Abstract

The texture of sausage was affected by its binding agent. Elephant foot yam (Amorphophallus campanulatus) flour was a potential natural binding agent and filler for sausage. The objective of this study was to evaluate the effect of elephant foot yam flour and soybean oil addition to the physicochemical properties and sensory attributes of beef sausage. A randomized block design with two factors and three replications were employed. Three addition levels (10%, 15% and 20% of meat weight) were used for both elephant foot yam flour and soybean oil. The results showed that the addition of elephant foot yam flour significantly (P≤0.01) affect the water-holding capacity (WHC) and sausage texture. The effect (P≤0.05) was also observed on the redness color (a* value). However, no effect was found on pH, L and b* values. On the other hand, the WHC and sausage texture were also significantly (P≤0.05) affected by soybean oil addition without altering pH and color. The highest addition level (20%) for both elephant foot yam flour and soybean oil showed a firm and compact beef sausage micro-structure with small pores. The highest fat and crude fiber content were also found in this group (20% addition level) and the sensory attributes (texture, aroma and taste) of the former group were comparable with the group with lowest addition level (10%). Therefore, elephant foot yam flour can be used as filler for producing both reduced-fat and typical beef sausage.

The materials were duck’s egg, water, salt, and essence of white turmeric. The method was experiment using Complete Randomized Design (CRD) with five treatments and three for replications. The Curcuma zedoaria juice research were divided into P0 (0%), P1 (10%), P2 (20%), P3 (30%) and P4 (40%). Data was analyzed using Analysis of Variance (ANOVA) and then continued by Duncan’s Multiple Range Test (DMRT), if it was found significant effect among treatmeants. The result showed that the addition of Curcuma zedoaria juice indicated highly significant different effect (P<0.01) on antioxidant activity, protein content and salt content, but significantly effect (P<0.05) on total phenol. The best treatment was the addition of Curcuma zedoaria juice 40% were indicated of antioxidant activity, total phenol, protein content and the salt content was 99.80 mg/g, 0.16%, 9.96%, 2.43% respectively.

Abstract

The objective of this study was to optimization antioxidant activity of active peptides of chicken feet with papain hydrolysis. The research method was experimental design conducted using Factorial Completely Randomized Design. Treatments included papain concentration (control (0%) , 1%, 2%  and 4%) and Incubation time (24 hours, 36 hours and 48 hours) were repeated four times. The variables observed were proximate analysis,microstructure, dissolved protein concentration and antioxidant activity. The results indicate that the treatment of papain concentration and incubation time variations in chicken feet protein extraction gave a differenceinfluence (P <0.05) to the concentration of solubility protein and antioxidant activity. The interaction of 3% papain concentration and 36 hours incubation time resulted in the highest  antioxidant activity amount 55.10 ± 2.24 %. It could be concluded that chicken feet produced bioctive peptide compound that gave high antioxidant activity optimized by hydrolysis of papain enzymes thereby increasing their functional value.

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.
