Abstract

Swiftlet’s clean and edible nest has been consumed for centuries as health food. The benefits of the edible bird nest (EBN) are commonly based on historical and observational reports since its discovery, until some were proven scientifically at recent times. The EBN has a potential to be a prebiotic with the bioavailability of glycan within the EBN. In order to test the prebiotic potential, the EBN glycoprotein and EBN extracted glycan went through a simulated human digestion in vitro test which contained at the level of oral, gastric and small intestine. The undigested components were collected and further tested with simulated in vitro human colon model. The findings showed that the improved growth of beneficial bacteria in the presence of EBN substrates have potentials to provide health benefits. The beneficial group of bacteria may improve and strengthened the host immune system and reducing the risk of pathogenic bacterial infection. These health benefits are crucial especially during the severe health situation such as the pandemic of COVID-19. This study had contributed to the functional properties of the EBN, as a prebiotic for the benefits of consumers and EBN industries. The fundamental of this finding in regards to prebiotic activity can be applied to the area of animal production in the application of prebiotics as value added animal feed ingredients.

Abstract

Organic waste has high COD and BOD content, so it is dangerous if disposed of directly into the environment. Organic waste processing, such as waste from livestock manure and liquid tofu waste, requires a process that can reduce COD and BOD levels as well as produce valuable products. Anaerobic digestion method is the proper process to convert complex compounds in waste into simpler compounds with methanogenic bacteria into a renewable energy product, namely biogas. On the other hand, the anaerobic digestion process can reduce COD and BOD levels in the biogas formation process. This study uses raw materials such as cow manure and chicken manure, and liquid tofu waste. The variables that produced the largest biogas were those with a ratio of 70% cow dung, 15% chicken manure, and 15% tofu liquid waste with a total of 3,251.5 mL. Then, the COD and BOD levels decreased significantly with more than 98% COD removal, and more than 95% BOD removal in all variables at the end of the anaerobic digestion process.

Abstract

A method to improve the physical quality of culled chicken meat is required due to the tough texture and faint color of culled chicken meat. High protein content in culled chicken meat makes it easy to experience quality degradation. One of the methods to maintain the quality of post-harvest chicken meat is using spices. Gelugur acid (Garnicia atroviridis) is a spice for cooking spice, sweets, herbs, deodorizing fresh fish, and even cleansing fish before it proceeds into the processing stage. This study aimed to determine the concentration of Garcinia atroviridis which is effective to improve the physical quality of culled chicken meat. This study used a randomized design with 4 treatments and 5 replications. The treatments consisted of T0: without marination using Garcinia atroviridis (as control), T1: marination in 50 g of Garcinia atroviridis + 1000 mL aquadest, T2: marination in 50 g of Garcinia atroviridis + 750 mL aquadest, T3: marination in 50 g of Garcinia atroviridis + 500 mL aquadest. The parameters were the physical quality of meat consisting of meat pH, water holding capacity, tenderness, cooking loss, drip loss and meat color. Based on the results of the study, Garcinia atroviridis marinade had significant effect (P <0.05) on the pH value of the meat, cooking loss, drip loss, tenderness, water holding capacity, and meat brightness. It was concluded that the marination of meat at concentration of 50 g of Garcinia atroviridis + 1000 mL aquadest (T1) was effective in maintaining the pH value, reducing meat drip loss, increasing water holding capacity, increasing tenderness, brightening the color of the meat and maintaining the freshness of the refined culled chicken meat. Marination of meat in concentration of 50 g Garcinia atroviridis + 750 mL aquadest (T2) was also effective in reducing cooking loss of culled chicken meat.
