Abstract

The purpose of this research was to determine the characteristic of physical properties and emulsifying activity index with different concentrations (0%, 1%, 3%, and 5% (v/v)) on the viscosity, solubility, turbidity, emulsifying activity index, and microstructure. The experiment was designed by Completely Randomized Design (CRD). The data were analyzed by Analysis of Variance (ANOVA) and continued by the Least Significant Difference (LSD) test. The addition of TiO2 with different concentrations gave a highly significant difference characteristic on syneresis, viscosity, solubility, turbidity, and emulsifying activity index (P<0.01) and the addition of TiO2 with different concentrations show the different effect on protein casein and chitosan aggregate. The surface microstructure of nanocomposite casein-chitosan addition of TiO2 for low-level concentration TiO2. It can be presumed presence of TiO2 as a photocatalyst indicated increasing the syneresis, viscosity, solubility, turbidity, and emulsifying activity index.

Abstract

The purpose of this research was to determine the best type and level of tapioca flour in rabbit meatballs based on pH, WHC, cooking loss, and color. Rabbit meat and tapioca flour were used as research materials. The method used is a laboratory experiment using a completely randomized design with a factorial pattern. Factor A is the type of tapioca flour, namely dragon tapioca flour and special tapioca flour. Factor B is the level of use of tapioca flour, namely 25% and 50%. The pH value, WHC, cooking loss, and color used as the analyzed variable. Data analysis used Analysis of Variance and if there was a significant effect, it was continued with Duncan's Multiple Distance Test or DMRT. The results showed that the treatment using different types and levels of tapioca flour had a highly significant difference effect (P < 0.01) on WHC, cooking loss, L, a*, and b* and had no effect (P>0.05) on rabbit meatball pH. It can be concluded that tapioca special flour with level 25% gives the best results on characteristic of rabbit meatball.

Abstract

Hypercholesterolemia is a disease that is indicated by the increasing level of cholesterol in the body and also as one of the factors causing cardiovascular disease. An alternative that can be done to prevent hypercholesterolemia is by consuming fermented milk. Skim milk is fermented using probiotic of Lactobacillus acidophillus, Lactobacillus plantarum and Streptococcus thermophilus. The skimmed milk that has been fermented is then tested for total lactic acid bacteria, total acid, pH, and in vivo analysis for antihypercholesterolemia activity using animal model. In this study, the animal models used were male white rats which were grouped into three treatment groups, namely negative control, positive control, and fermented milk group. The result of the study shows that the total lactic acid bacteria, total acid and pH of fermented skim milk were 5.25 x109 CFU/ml; 2.190% and pH 4.06, respectively. From the results, fermented milk with probiotics has the ability to reduce cholesterol levels in the blood of male white rats effectively in vivo.

Abstract

The effects of gaseous ozone exposure on the physical and oxidative properties were evaluated in chicken breast fillets, which were pretreatment of gaseous ozone, ultraviolet, edible coatings and stored at 8°C (refrigerator), 27°C (closed pack), and 27°C (opened pack) for 4 d. The physical and oxidative properties of chicken meat are maintained after preozonation treatment is then applied to the edible coating. pH of chicken meat given ozone, UV and edible coating and stored at refrigerator that a pH closest to the normal chicken meat pH of 5.87. Combination of ozone, UV and edible coating has and the highest water holding capacity value and TBA value but the lowest cooking loss value. The brightness level of chicken meat coated in edible coating and stored at various temperatures showed a difference. The ability to store longer or with an increase in storage temperature, besides that, it can add value to the bioactive antioxidant and antimicrobial components.

Abstract

Microbial contamination and fat oxidation may cause physical and chemical changes that can reduce the quality of broiler meat. The objective of this study was to determine the ability of casein chitosan edible coatings in maintaining the quality of broiler meat stored in certain storage time under refrigeration (8 oC), in terms of water activity (Aw), cooking loss, organoleptic properties (i.e. color, aroma and possible deviations), physicochemical properties (i.e. moisture content, water holding capacity/WHC, pH, lipid content, color), Total Plate Count (TPC), and microbial properties (i.e. Staphylococcus aureus, Escherichia coli, and Salmonella sp.). The materials used were broiler breast fillets and casein chitosan edible coating. The research was conducted using a Completely Randomized Design (CRD) based on 5 variations in storage time treatments i.e. at 0 h; 24 h; 72 h; 120 h; and 168 h in 4 replications. Edible coating casein chitosan on broiler meat under storage showed significant on Aw, WHC, pH, lightness, TPC, S. aureus, and E. coli. The application of casein-chitosan as an edible coating could be suitable to assure the safety of food products such as chicken meat at the range of storage time studied.

Abstract

Casein is one of the milk proteins which have the unique characteristic, it is called assembly. Assembly is casein can interact with casein or others to form micelle casein nanoparticle. The nano size of casein can accelerate the process of absorption into the body, making it suitable as a delivery system of nutraceutical food. It can happen with the appropriate temperature. According to the statement, this research aims to determine the best temperature for the reassembling process of casein with phenolic at different temperature (40°C, 50°C, and 60°C) with four replications.
