Abstract

Chicken meat constitutes a significant source of animal protein in the Indonesian diet; however, its perishable nature results in a decline in quality during storage. The objective of this study was to evaluate the chemical characteristics of chicken meat coated with gelatin-basil leaf extract during cold storage. The present study employed a randomized experiment, incorporating three distinct treatments and five replicates. The treatments comprised cold storage duration (0, 3, and 6 days). The results demonstrated a significant effect (p<0.01) on the pH value, moisture content, water-binding capacity, and L a b color of chicken meat coated with chicken foot gelatin-basil leaf extract. The utilization of gelatin-basil leaf extract coating has been demonstrated to retard the decline in pH and moisture content, thereby preserving the water-binding capacity of chicken meat. Despite the decline in pH and color over time, the efficacy of the coating in preserving the quality of chicken meat, particularly during the initial storage phase, was demonstrated. The gelatin-basil leaf extract coating has been shown to contribute significantly to the prolongation of the freshness of chicken meat by slowing down the acidification and oxidation processes.

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 male Peking duck is a type of meat duck that has great potential to be developed as a producer of carcasses and primal carcass cuts. The research was carried out with the aim of finding out the best level of addition of pineapple peel fermented yeast (Saccharomyces cereviceae) culture to the percentage of carcasses and carcass primal cuts of male Peking ducks. The material used in this research was 240 male Peking ducks with an initial weight of 343.90 ± 0.90 g. The ration used contains 16% crude protein, with a metabolic energy (ME) of 2.900 kcal/kg. The cage system used is a battery colony cage measuring 200 cm x 60 cm x 50 cm with 30 plots. Each plot contained eight male Peking ducks which were kept until 8 weeks of age. The research data were analyzed using One Way Anova based on a Completely Randomized Design with a unidirectional pattern and followed by the Duncan Multiple Range Test (DMRT) using the SPSS version 16 program. The research results showed that the treatment with the addition of 10% fermented pineapple peel in the ration (P2) could produce a male Peking duck carcass percentage of 55.52% higher than the P0 treatment (54.94%); P1 (54.11%); P3 (53.85%); P4 (53.61%) and P5 (52.07%), while in primal carcass cuts the highest percentage was found in the chest at 37.17%, followed by the back (22.67%), wings (13.96%), lower thighs (13.72%) and upper thighs (12.43%).  Conclusion: The addition of yeast (Saccharomyces cereviceae) culture fermented pineapple peel at a level of 10% in the ration can produce a higher percentage of carcasses and carcass primal cuts of male Peking ducks compared to other treatments.

Abstract

The mold Aspergillus flavus produces a metabolite molecule called aflatoxin. Aflatoxin chemicals can have harmful effects on both humans and livestock when they are present in feed ingredients. Aspergillus flavus frequently grows on corn, one of the feed ingredients. Examining the amount of aflatoxin contamination in corn in North Lombok Regency and how it affects laying hen performance was the goal of this study. Random sampling was done from each subdistrict, and descriptive analysis was done on the collected data. According to the study's findings, aflatoxin compounds, which have a range of 87.99–132.38, were found in 50% of corn. Aflatoxin concentration in feed surpasses the 60 ppm SNI guideline by 33.33%.  Performance is impacted by aflatoxin compounds in maize; specifically, 50% of feed intake, 50% of egg weight, and 100% of noncompliance with SNI and corporate criteria are not met. The results of this study suggest that aflatoxin levels in diet have an impact on laying hens' declining performance.

Abstract

Edible films are thin films made of hydrophilic materials such as protein, which function as packaging materials that provide a preservation effect, act as a barrier to oxygen, reduce water evaporation, and improve product appearance. The objective of this study was to ascertain the impact of varying glycerol concentrations on the thickness, gelation time, and microstructure of protein-based films. This study employed a Completely Randomized Design with three treatments and three replicates. The treatments consisted of G1: 1.25 ml glycerol; G2: 1.5 ml; and G3: 1.75 ml. The protein-based film produced thickness values of 0.215-0.288 mm, gelation time of 1380-1381 seconds and uniform microstructure. The glycerol concentration of 1.25 ml produced the most favourable film characteristics, in comparison to other concentrations. These included a thickness value of 0.215 mm, a gelation time of 1380 seconds and a more continuous microstructure, characterised by an even distribution of the main film-forming components.

Abstract

Edible film is a thin film that can be eaten or consumed directly and serves as a barrier to water vapour, light, gas, fat, and other solutes. Edible film has biodegradable properties that reduce environmental damage. The purpose of this study was to determine the effect of chia seed addition with different concentrations on the thickness, water vapour transmission rate (WVTR), and microstructure of protein-whey gelatin-based edible film. The study employed a completely randomized design comprising three treatments and three replicates. The treatments comprised the addition of chia seeds at different concentrations, namely C1 (0.05 ml), C2 (0.10 ml) and C3 (0.15 ml). The collected data were analysed using Analysis of Variance (ANOVA), with significant differences being followed by Duncan Multiple Range Test (DMRT). In addition, microstructure measurements were analysed descriptively. The addition of different concentrations of chia seeds resulted in a significant difference (P < 0.01) in the thickness value of whey-gelatin protein-based edible films, but no difference (P > 0.05) in the WVTR of whey-gelatin protein-based edible films. The study produced edible films with thickness values of 0.294–0.304 mm, WVTR of 4.57–5.41 g/mm²/day. The use of chia seed at a concentration of 0.10 ml produces a film with good thickness and WVTR values in comparison to other treatments. The resulting thickness value is 0.302 mm, while the WVTR is 4.57-5.41 g/mm²/day. Furthermore, the film microstructure is denser and more uniform.

Abstract

A thin layer of material added directly to food products that comes from consumable sources is called an edible film. Proteins can be used to create edible films with barrier qualities against oxygen, moisture, and smell, making them appropriate for use as packaging materials that improve product appearance and have preservation effects. Finding out how different glycerol concentrations affect the thickness, gelation duration, and microstructure of protein-based films is the aim of this investigation. A completely randomized design with three treatments and three replications was used in this investigation. The treatments comprised distinct glycerol concentrations, designated as P1 (35%), P2 (40%), and P3 (45%). The protein-based films exhibited thickness values of 0.108–0.113 mm, gelation times of 16.00–20.67 minutes, and a uniform microstructure. At higher concentrations, such as 45%, glycerol resulted in increased porosity and aggregation within the polymer matrix, which in turn led to a reduction in the homogeneity and mechanical strength of the films.  A glycerol concentration of 35% proved to be the most effective treatment for the production of a whey-gelatin-based edible film, resulting in a smooth surface and an even distribution of glycerol within the protein matrix. This approach effectively reduced the occurrence of cracks or irregularities.

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.
