Coconut Oil

Mandar coconut oil is one of the coconut processed products, which has become superior product in West Sulawesi especially in Majene regency. Unfortunately, the Mandar coconut oil can’t be used more than a month because the water content and free fatty acid content of the oil have exceeded the maximum standard of SNI, so it can adversely affect on health. On the other hand, the existence of rice husk in Indonesia itself especially in West Sulawesi has not received attention and is limited to a few needs such as for ash or livestock feed, and the rest is thrown away. This research aims to determine the effect of rice husk ash addition on the increasing of Mandar coconut oil quality. Completely randomized design was used in this research with 6 rice husk ash concentration variation levels i.e. 0%, 5%, 10%, 15%, 20% and 25%. The result shows that the addition of rice husk ash with 10% to 25% can reduce the water content of the oil until the quality standard of SNI is full filled. The highest reduction of water content was reached with 25% of rice husk ash concentration with 81% of reduction percentage. While, the addition of rice husk ash with 15% concentration can reduce the free fatty acid content of Mandar coconut oil until 32%.

The application of high intensity, pulsed infrared radiation for roasting of groundnuts is attempted and the product quality is compared with that of the conventionally roasted samples. Product qualities such as lightness (color), compressive strength (texture) and free fatty acid content are analyzed for different combinations of roasting duration (4-12 min) and temperature (160-200°C), selected based on central composite rotatable design (CCRD). Pulsed infrared roasting at 178-188°C for 6.8-9.2 min resulted in optimum product quality in terms of color, texture and free fatty acid content. The other parameters such as oil and moisture content, peroxide value and sensory characteristics of roasted nuts are also evaluated for the select temperature-duration combinations. The oil yield increased marginally with roasting duration and temperature. Peroxide number, an indicator of the stability of fat, did not vary during infrared roasting. Groundnuts processed at 180°C for 8 min scored high in terms of sensory attributes. Infrared roasting resulted in better product quality as compared to drum and sand roasting.

Variable Energy

Fats are important but variable energy-yielding ingredients in diets for broilers. One of the factors that may affect the dietary energy value of fats is the proportion of free fatty acids which, together with rate of inclusion of fat and the age of the bird, must be considered in fat evaluation. The current experiment was designed to investigate the effect of free fatty acid content of tallow on the apparent metabolisable energy values for broilers.Tallow and tallow acid oil (Table 1) were obtained for evaluation. Tallow (A) of free fatty acid content 138.4 g/kg was hydrolysed to produce a fat (E) of free fatty acid (FFA) content 952.1 g/kg. Fat A and B were blended in the proportions A75:B25, A50:B50 and A25:B75 giving fats of 341.5, 545.3 and 748.7 g/kg FFA respectively which were included at rates of 40 g/kg, 80 g/kg and 120 g/kg at the expense of the energy-yielding ingredients. The 16 experimental diets - basal (Table 2) together with 15 containing fats - were evaluated with Ross 1 broiler chicks of 1.5 weeks (5 replicates of cage of 2 birds) and 7.5 weeks of age (5 replicates of cage of 1 bird).
