Abstract

Edible film is a thin, edible film used as a food coating. The advantages of edible film include its biodegradability and its ability to maintain the quality and shelf life of the food product it covers. The objective of this study was to ascertain the impact of varying concentrations of sorbitol on the thickness, water vapor transmission rate, and microstructure of whey-chia seed edible film. The present study employed a Completely Randomized Design, comprising three distinct treatments, each with three replicates. The data obtained were analysed using Analysis of Variance, and if there were significant differences between treatments, these were followed by Duncan Multiple Range Test. The treatments incorporated the following: P1 (10% sorbitol), P2 (20% sorbitol), and P3 (30% sorbitol). The variables measured in this study were thickness, water vapor transmission rate and edible film microstructure. The findings demonstrated that the incorporation of sorbitol at varying concentrations elicited a highly significant effect (P<0.01) on the thickness of the edible film. However, the water vapor transmission rate test did not yield a significant difference (P>0.05). The mean thickness of the samples ranged from 0.0296 to 0.0303 mm, and the water vapor transmission rate ranged from 4.60 to 5.68 g/mm²/day. Microstructure analysis revealed that the incorporation of sorbitol enhanced the flexibility and uniformity of the distribution of the films at concentrations of 10% and 20%. However, at a concentration of 30%, the films exhibited increased rigidity and reduced flexibility. The utilization of a 20% sorbitol concentration was identified as the optimal treatment.

Abstract

Oyster mushrooms are a healthy alternative food source for reducing the fat content of sausages due to their low fat content. Chicken sausage is a processed meat product that typically contains meat, binders, and fillers. This study aimed to investigate the physical and microbiological properties of chicken sausage with varying concentrations of oyster mushrooms, which are added to improve its quality. The study employed a completely randomized design with three treatments. If a treatment showed a difference, the Duncan Multiple Range Test was conducted. The treatments consisted of J0: 0% oyster mushroom, J1: 1% oyster mushroom, and J2: 2% oyster mushroom. Statistically, the use of different concentrations of oyster mushrooms did not result in a significant difference (P>0.05) in the water binding capacity, breaking power, pH, and total plate count of chicken sausages. However, the addition of oyster mushroom concentrations can improve the physical and microbiological quality of the sausages. The addition of different concentrations of oyster mushroom to chicken meat sausage resulted in a water binding capacity of 39.28-46.12%, breaking strength of 0.4-0.5 kg/cm2, pH value of 6.46-6.56, and total plate count of 1.57-1.86 cfu/g. The treatment that yields the highest water binding capacity (45.06%), breaking power (0.04 kg/cm2), pH (6.56), and total plate count (1.57 cfu/g) is the addition of 1% oyster mushroom concentration. The concentration of oyster mushroom used in the preparation of chicken meat sausages should not exceed 1% of the total sausage mixture.

Abstract

The utilization of local feedstuffs is a cost-effective strategy to reduce production expenses in animal husbandry. Enhancing the nutritional quality of these feedstuffs through fermentation presents a viable approach. This study investigates the efficacy of cellulolytic bacteria in degrading fiber in three local feed materials: duckweed (Lemna minor), water hyacinth (Eichornia crassipes), and lamtoro (Leucaena leucocephala). We employed a completely randomized block design with feed types as the block and levels of starter culture as treatment. Pediococcus pentosaceus, identified for its cellulase enzyme production with a clear zone of 4 cm on starch media, was utilized as the starter culture. The experimental procedure involved spraying Pediococcus pentosaceus onto duckweed, water hyacinth, and lamtoro, followed by incubation. The results indicated that Pediococcus pentosaceus effectively produced cellulolytic enzymes and significantly reduced crude fiber in duckweed by 18.18%, in water hyacinth by 9.17%, and in lamtoro by 4.23% (p < 0.05). Additionally, the crude protein content increased in all samples: by 4.69% in duckweed, 2.71% in water hyacinth, and 2.13% in lamtoro (p < 0.05). Among the treatments, the optimal outcome was achieved with 3 ml of Pediococcus pentosaceus. This study demonstrates the potential of Pediococcus pentosaceus for improving the nutritional profile of local feedstuffs through fermentation.

Abstract

The objective of this study is to ascertain the impact of employing natural coagulants, namely eggplant para (Solanum indicum), biduri sap (Calotropis gigantea), and papaya sap (Carica papaya L.), on the chemical properties, antioxidant levels, and organoleptic properties of palopo. The present study employed a Completely Randomized Design (CRD), utilizing three natural coagulant treatments (eggplant, biduri sap, and papaya sap) each at 0.2% of the sample weight, with five replicates. The research variables encompassed pH, water content, ash, crude protein, crude fat (utilizing the proximate analysis method), antioxidant content (employing the DPPH method), and organoleptic values (aroma, taste, colour, texture, and overall acceptance) (using the hedonic method). The findings indicated that the type of coagulant employed exerted a highly significant effect (P<0.01) on the water content, protein and antioxidant levels of palopo, while no significant effect (P>0.05) was observed on pH, fat content, and ash content. The utilization of eggplant (Solanum indicum) as a natural coagulant resulted in a high level of protein in palopo (7.33%), while the application of papaya latex (Carica papaya L.) led to a higher level of antioxidants in palopo (80.05%) compared to other types of coagulants. The incorporation of natural coagulant eggplant parboil can yield palopo that is particularly prized for its optimal texture and palatability. Conclusion: The incorporation of natural coagulant Eggplant (Solanum indicum) in the manufacturing process of palopo ensures optimal chemical quality and acceptance, while papaya latex (Carica papaya L.) contributes the highest antioxidant content, thereby possessing the potential to enhance the functional value of the product.

Abstract

Edible film is a thin layer that can coat food products and protect them from physical, chemical, and microbiological disturbances. This study aimed to determine the effect of the concentration ratio and different plasticizers on the thickness, water vapour transmission rate, and morphology of protein-based edible films. The study used a completely randomized design with a factorial pattern. The experiment involved two factors: Factor A, which was the whey-gelatine concentration ratio, at three levels (A1 = 1:0.5; A2 = 1:0.75; A3 = 1:1); and Factor B, which was the plasticizer, at two levels (B1 = glycerol; B2 = polyethylene glycol (PEG)). The study revealed that the water vapour transmission rate was significantly affected (P<0.01) by the interaction between whey-gelatin and different types of plasticizers. Additionally, the film thickness was significantly affected (P<0.01) by the whey-gelatine ratio, and the water vapour transmission rate was significantly affected (P<0.01) by the different types of plasticizers used. The film made from protein had a thickness of 0.282-0.357 mm, a water vapour transmission rate of 4.27-5.55 g/mm2.h, and a homogeneous surface structure resulting from the good mixing of whey and gelatin. The concentration of whey-gelatine and the use of different plasticizers can affect the thickness, WVTR, and morphology of the film. The use of glycerol as a plasticizer resulted in a greater thickness, water vapour transmission rate (WVTR), and morphology compared to those of the PEG plasticizer when the whey-gelatin concentration was 1:1.

Abstract

SEM testing was used to evaluate the homogeneity of the film, including pores, cracks, and surface structure, as well as to determine the cross-section and surface structure and the homogeneity of the film solution mixture. The study aims to determine the microstructure characteristics of whey film by adding different concentrations of chia seed and 35% sorbitol as a plasticizer. This study employed three treatments: P1 with 0.5% chia seed, P2 with 0.75% chia seed, and P3 with 1% chia seed. The research method used was descriptive, providing a detailed description of the process. The results indicate that adding more polymer increases the viscosity of the film suspension during the gelatinization process. The film's microstructure was determined by the heating and drying process, as well as the contribution of chia seed gel to the whey film structure. All treatments achieved a Homogeneous film microstructure, but the 1% concentration treatment resulted in a swollen surface structure. The chia seed was evenly mixed into the whey protein matrix, resulting in a uniform structure.

Abstract

This study aims to compare phosvitin isolation procedures from chicken egg yolk based on purity level, time efficiency, and functional activity. The procedures compared include previously published methods and modified methods developed in this study. Phosvitin was isolated from 10 samples of native chicken eggs collected from farms in the Mataram area using a stratified random sampling approach. The isolation process involved several sequential steps: sedimentation, centrifugation, dialysis, and lyophilization. A comparative analysis of the two procedures was conducted based on protein profile characteristics using SDS-PAGE and Fourier Transform Infrared (FTIR) spectroscopy to identify phosphate group interactions and metal ion binding. SDS-PAGE results showed that both procedures yielded α-phosvitin (35 kDa) and β-phosvitin (45 kDa) protein bands. FTIR spectra confirmed that both phosvitin samples contained high levels of phosphate groups, indicating strong phosphorylation and good protein stability. From a chemical and biological standpoint, the modified procedure showed no qualitative differences compared to the previously established method. However, the modified protocol was approximately 30 minutes faster and did not require a pH adjustment step, making it a simpler and more time-efficient alternative for isolating phosvitin from egg yolk.
