Chicken rendang is loved by children and adults alike but is still often found in restaurants in Padang City. As a representative of the Minang Region, the city of Padang is very representative of sampling chicken rendang because each rendang has a different process and taste. This research examined the quality, nutritional value, and taste of chicken rendang sold in Padang City. The method used in this research was a survey method with random sampling (purposive sampling), and then laboratory analysis was carried out. Data processing used a 9x2 randomized block design (nine samples and two groups), with samples being places where chicken rendang was taken from 8 restaurants in the city of Padang and one chicken rendang sold commercially (packing) as a control, while quality test without using controls. The parameters observed were quality (FFA, TBA, and cholesterol levels), nutritional value (moisture content, protein content, fat content, ash content), and sensory analysis (color, aroma, texture, and taste of 30 untrained panelists) of chicken rendang. Sample G had the highest nutritional value but was lower than the sensory analysis. On the other hand, the sample I had the highest sensory assessment and high-fat content. Sample D was the best sample regarding quality, nutritional value, and sensory with FFA 0.800%, TBA 0.021 mg malonaldehyde/kg, cholesterol levels 44.35 mg/dl), nutritional value (moisture content 45.03%, protein content 14.48%, fat content 15.44%, ash content 2.80%), and sensory analysis neutral.

2023-12-28T01:25:23+00:00

The chicken head is one of the by-products with a high protein content. Therefore, chicken heads can be used as raw materials to produce protein hydrolysates containing bioactive peptides that have biological activities, such as antibacterial, anti-inflammatory, and antioxidant activities. This research aimed to evaluate the use of the combined ratio of papain and bromelain enzymes to produce chicken head protein hydrolysate that has antibacterial activity. The research method used in this study was a laboratory experiment using a completely randomized design (CRD) with four treatments and five replications. Statistical significance was done using one-way analysis of variance (ANOVA) followed by Duncan’s multiple range test (DMRT). The inhibition zones of chicken head protein hydrolysate using a combination of papain enzymes against Lactobacillus casei, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonella typhimurium were 1.72-2.68, 1.19-4.47, 0.93-1.45, 1.64-2.46, and 1.01-3.62 mm, respectively. The result showed that the highest antibacterial activities against Lactobacillus casei, Escherichia coli, and Staphylococcus aureus were in A1 (hydrolysis using papain 75% and bromelain 25%), the highest antibacterial activities against Pseudomonas aeruginosa was in A3 (hydrolysis using papain 25% and bromelain 75%), and the highest antibacterial activity against Salmonella typhimurium was in A2 (hydrolysis using papain 50% and bromelain 50%). However, all the hydrolysate didn’t exhibit antibacterial activity against Bacillus subtilis. Chicken head protein hydrolysate had the potential to be an antibacterial agent against pathogenic bacteria.

2024-02-16T09:38:00+00:00

This research examined the effect of chitosan and beeswax edible coating with different percentages on the microbiological value (aerobic bacteria, Staphylococcus aureus, Coliform, and Escherichia coli) of chicken thigh meat in two days of storage at freezer temperature (-18^oC to -20^oC). The study used Completely Randomized Design with 4 treatments and 5 replications. Treatments included were A0 (control), A1 (chitosan 2%), A2 (chitosan 2% + beeswax 1%), and A3 (chitosan 2% + beeswax 2%). Variables observed were the number of aerobic bacteria, S. aureus, Coliform, and E. coli using 3M^TM Petrifilm^TM Plates. Results showed significant differences (p<0.05) in the number of aerobic bacteria colonies with the least colony on treatment A1. S. aureus and Coliform colonies showed significant differences (p<0.05) with the least colony on treatment A2 and A3, sequentially. There was no significant difference (p>0.05) in E. coli count due to no colonies detected on all treated samples. However, compared to controlled samples, it was found to decrease. The decrease in colony numbers shows that edible coating treatments can be used to help preserve or extend the shelf life of chicken thigh meat.
