Abstract

Lipid is an essential source in fish feed production. Vegetable or fruit oil is becoming preferred by many fish feed manufacturers to replace fish oil, which is expensive and scarce. Buah Engkabang (Shorea macrophylla) is well known as the largest genera of the Dipterocarpaceae family and is a popular local fruit collected in tropical forests or nearby rivers in West Kalimantan (Indonesia) and Sarawak (Malaysia). Buah engkabang is seasonal fruit during the dry season, known among the Sarawak locals as a climatic species that ripens between January and March in a favorable environment. This review emphasizes morphology characteristics and phytochemical properties, including fatty acid components. In addition, this review also reviewed the application of engkabang oil in feed production, cooking oil, and other edible products. The high content of saturated fatty acids like palmitic acid, stearic acid, and oleic acids in engkabang product could be essential as the potential omega-six lipid source suitable for freshwater fish like empurau, kelah, and other local fish species found in riverine of Borneo. This eview will provide information on the potential use of buah engkabang as a future lipid source in fish feed production.
