Analysis of the sex of cattle meat by fast and reliable molecular techniques is an important measure to ensure correct allocation of export refunds, particularly in European countries and also in countries such as India where female cattle (cow) slaughter is banned legally in many areas because of religious beliefs. Based on the male-specific SRY gene, X and Y chromosome specific amelogenin gene 2 pair of primers was designed and the system of PCR was optimized. Upon PCR amplification, male tissue showed 3 bands, while female tissue resulted in only 1 band. The accuracy and specificity of the primers were assessed using DNA template extracted from cattle meat of known sex. The protocol was subjected to a blind test and showed 100% concordance, proving its accuracy and reliability. © 2012 Copyright Taylor and Francis Group, LLC.

A simple and sensitive liquid chromatographic (LC) method was developed for determination of carbaryl residue in buffalo meat samples. This method is based on a solid-phase extraction technique followed by high-performance liquid chromatography (HPLC)-photo-diode-array (PDA) detection. Meat samples (0.5 g) were deproteinized by adding acetonitrile followed by centrifugation and filtration. The analyte was separated on a reverse-phase (RP-C18) column using isocratic elution. Acetonitrile along with water appears to be an excellent extractant as recovery of the analyte in spiked sample at maximum residue level (MRL) was 98.5%, with coefficient of variation (CV) of 4.97%. The limit of detection (LOD) and limit of quantification (LOQ) of the method was 0.015 and 0.03 μg g-1, respectively. The linearity of the carbaryl was 0.9992. Excellent method repeatability and reproducibility were also observed by intra- and inter-day assay precision. For robustness, the method was employed to analyze 122 buffalo meat samples, and intensities for the insecticide were found to be unaffected by the sample matrices interference. © 2010 The Royal Society of Chemistry.

A three factor Box-Behnken design of response surface methodology was employed to optimize spent hen meat level (600–700 g kg−1), oil level (25–75 g kg−1) and cooking time (3–5 min) for development of ready-to-eat chicken meat caruncles on the basis of sensory attributes - colour/appearance, flavour, crispiness, after-taste, meat flavour intensity and overall acceptability. The analysis of variance showed that meat and cooking time interaction showed significant effect (p < 0.01; p < 0.05; p < 0.1) on colour/appearance and crispiness of chicken meat caruncles. Quadratically meat level showed significantly higher effect (p < 0.01; p < 0.05; p < 0.1) on crispiness; and oil level and cooking time (p < 0.05; p < 0.1) on after-taste of chicken meat caruncles. Linearly meat level showed significantly higher (p < 0.05; p < 0.1) effect on colour/appearance, after-taste, meat flavour intensity and overall acceptability of chicken meat caruncles. The optimized conditions were: 650 g kg−1 meat level, 50 g kg−1 oil level and cooking time as 4 min. Among all sensory parameters, crispiness is one of the most important sensory parameters for meat snacks, which was highest (6.68) at the optimized conditions in the final product. The other sensory parameters ranged from 6.33 to 6.68 on an eight point scale. Box-Behnken design of RSM performed well in the optimization process of development of chicken meat caruncles to produce product with very high degree of acceptability. 650 g kg−1 of spent hen meat level produced the most acceptable product in terms of sensory profile. © 2013, Association of Food Scientists & Technologists (India).

The storage stability of enrobed goat meat bites (EGMB) incorporated with 3 % crude aloe vera (AV) gel was evaluated under aerobic (T-1; unenrobed control product, T-2; enrobed AV treated product) and modified atmospheric packaging (MAP, 50:50, CO2 and N2) (T-3; unenrobed control product, T-4; enrobed AV treated product) at 4 ± 1 °C for 42 days on the basis of physico-chemical, microbiological and sensory attributes. The pH value was higher, whereas water activity (aW) was lower in enrobed and MAP product. Thiobarbituric acid reacting substances (TBARS) and free fatty acid (FFA) values were significantly (P < 0.05) lower in MAP packaged (T-3) and AV treated products (T-2 and T-4) products than aerobic packaged (T-1), however it followed an increasing trend in all the products throughout storage. Instrumental colour and textural profile attributes were better maintained in MAP products than others. The sensory panellists graded T-4 ‘good to very good’ even on Day 42, whereas T-1 was acceptable only up to 28 days. Standard Plate Count (SPC) was significantly (P < 0.05) lower in MAP products than aerobic packaged products. Results concluded that EGMB treated with AV gel can be successfully stored more than 42 days under MAP conditions without affecting its physico-chemical, textural, microbiological and sensory attributes. © 2014, Association of Food Scientists & Technologists (India).

China is Africa’s largest trading partner, providing demand for the continent’s energy and minerals, and its direct investments in the continent are also on the rise. When Chinese Premier Li Keqiang visited the African Union in 2014, he announced that China would raise its direct investment in the continent to $100 billion by 2020, mostly in infrastructure development. While Chinese companies have been involved in Africa’s energy industry for years, particularly in hydro-electricity and fossil fuel extraction, the rise of China’s involvement in the continent’s renewable energy sector is relatively recent and an area ripe for further research. New research, which aims to better understand China’s investment in South Africa’s renewable energy sector, will help provide some answers. Lucy Baker, from the Science Policy Research Unit at the University of Sussex and Wei Shen, from the Institute of Development Studies, have received a fellowship to better understand the drivers and obstacles to the expansion of Chinese renewable energy activities in South Africa. There has been growing Chinese involvement in the wind and solar PV industries under South Africa’s renewable energy independent power producers’ procurement programme (RE IPPPP), a competitive bidding system for renewable energy generation by independent power producers. The research will focus on how Chinese companies and investors are involved in South Africa’s renewable energy, including their engagement in project development, investment, technology supply and manufacturing. The research will also consider implications for Chinese involvement in emerging renewable energy development elsewhere in the region and for other middle-income economies with a significant renewable energy programme under development, such as Argentina, India and Brazil. Their findings will be shared as a policy brief to be published by SAIS-CARI. The SAIS-CARI Fellowship they have been awarded allows researchers, policy-makers, or journalists to do field research on an under-explored policy issue related to China’s African engagement.
