Fat replacer is food ingredients used to mimic and replace animal fat in food products. The demand of low saturated fat in food products increase because of health concerns related to degenerative disease. Vegetable oil in a liquid state must be solidified to mimic animal fat by the emulsification process. This study aims to create and formulate fat replacer using palm olein and palm stearin as a source of unsaturated fatty acid. The formula was composed with vegetable oil concentration of 30% (K1), 35% (K2), 40% (K3), 45% (K4), and 50% (K5). A concentration of 15% fat replacers emulsion was added to make a meat analogue. Proximate analysis from all treatments showed that meat analogue has water content in the range of 53.90–57.56%, ash content of 2.87–3.10%, protein content of 9.04–15.32%, fat content of 13.22–19.13% and carbohydrate content of 2.35–2.53%. Oil concentration in fat replacer affected to the texture and sensory properties of meat analogue. The results indicate that the five treatments comply with the national quality standards for meat sausages.
Community development is expected to increase the level of economic and social welfare, especially for people living in rural area. The pandemic is one of the causes of economic downturn in the rural area. Entrepreneurship is one thing that can be done to earn income in the rural area. Reflecting on the current conditions, the community needs to adopt technology and increase the potential capacity of existing resources to maintain the economy on a household scale. Aquaponics is a fish cultivation technique combined with plants, especially vegetables. Optimization of resource utilization through the cultivation of lelekung (catfish and water spinach) using buckets and biofloc ponds needs to be tested through socialization and training to the community, so that the feasibility of the technology for the Nagori Pematang Panombeian community can be determined. The level of feasibility can be seen from the success of obtaining benefits from the cultivation process of these two technologies. The integration of catfish and water spinach cultivation through biofloc shows success based on the benefits obtained from rural communities using biofloc.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
