extracted fat from lamb Meat by supercritical co2 as feedstock for biodiesel production
Biochemical Engineering Journal, 2011Co-Authors: Hanifa Taher, Sulaiman Alzuhair, Ali Almarzouqui, I B HashimAbstract:Abstract The feasibility of enzymatic production of biodiesel from waste animal fats using supercritical fluid technology for the extraction and reaction has been investigated. The operating conditions that resulted in the optimum extraction and biodiesel production yields were identified. The effects of extraction temperature, pressure and supercritical CO2 (SC-CO2) flow rate were investigated in the ranges of 35–55 °C, 300–500 bar and of 3–5 ml min−1, respectively, and optimized using response surface methodology (RSM). In addition, the effects of reaction temperature, methanol:fat molar ratio and enzyme loading on biodiesel production yield were investigated in the ranges of 35–60 °C, 3:1–6:1 and 10–50%, respectively. The optimum conditions for supercritical fluid extraction (SFE) were determined to be 45 °C, 500 bar and 3 ml min−1; at which, 87.4% of total fat content was extracted from freeze Dried Meat. The statistical analysis however, showed that pressure has negligible effect on the extraction yield, which is extremely important, as it allows saving energy by using lower pressure. On the other hand, biodiesel yield of 40% was obtained using extracted fat as feedstock in SC-CO2 medium at 50 °C, 200 bar, 4:1 methanol:fat molar ratio and 30% loading of lipase enzyme, after 24 h of reaction. The experimental results were used to fit a suitable reaction kinetic model using non-linear regression analysis to estimate the model parameters.

Physicochemical and microbiological characteristics of biltong, a traditional salted Dried Meat of South Africa
Meat Science, 2014Co-Authors: Thomas Petit, Yanis Caro, Anne-sophie Petit, Sunita J. Santchurn, Antoine CollignanAbstract:The microbiological and physicochemical characteristics of several commercial beef, kudu and springbok biltong samples from South Africa were assessed in this study. Analysis of samples allowed their differentiation into ‘dry’ and ‘moist’ samples. Dry biltong showed low moisture content (21.5–25.3 g/100 g), a low water activity (0.65–0.68) and a high salt content (5.5–7.9 g/100 g), while moist biltong showed a higher moisture content (35.1–42.8 g/100 g), a higher water activity (0.85 to 0.89) and a lower salt content (3.8–5.6 g/100 g). The pH value did not vary significantly between both groups (5.00–6.26). The results showed that dry biltong presented a low total plate count (TPC) content, a high level of lactic acid bacteria (LAB) and a high level of d-lactic acid as compared to moist biltong. These results suggest that dry biltong complies with the standard hygienic quality (TPC < 7 log cfu/g in agreement with the Food Standards Agency), while moist biltong samples generally showed a low content of d-lactic acid and a low ratio LAB/TPC.
