JAOCS article of the month: E-tongue discrimination of monovarietal olive oils

“Simple and cost-effective techniques for evaluating physicochemical and sensory attributes of olive oil for traceability, authenticity, adulteration and legal purposes are needed,” says Journal of the American Oil Chemists' Society (JAOCS) Editor-in-Chief James Kenar. In Kenar’s choice for JAOCS article of the month, António M. Peres at the Instituto Politécnico de Bragnaça, in Portugal, and colleagues have coupled a potentiometric electronic tongue with chemometric analyses to discriminate the geographical origin, olive cultivar and quality grade of monovarietal Tunisian olive oils from nearby regions experiencing similar climatic and agroecological factors. The results show good sensitivity and demonstrate this technology as a possible strategy for olive oil analysis. The article is available for free download through April 20.

Lipids paper of the month: Berberine, cardiolipin, and mitochondrial function

The Lipids paper of the month, selected by Editor-in-Chief Eric Murphy, is "Berberine inhibits oxygen consumption rate independent of alteration in cardiolipin levels in H9c2 cells" by Grant Hatch at the University of Manitoba, in Canada, and colleagues. Berberine is a plant alkaloid that reduces blood glucose levels to a similar extent as the commonly used anti-diabetes drug metformin. However, some studies suggest a negative impact of berberine on cell proliferation via an alteration in mitochondrial function. Using H9c2 cardiac myocytes, Hatch and colleagues demonstrate that berberine results in a rapid, concentration-dependent reduction in the mitochondrial oxygen consumption rate. Because cardiolipin is a mitochondrial phospholipid essential for mitochondrial function, the researchers assessed the impact of berberine on cardiolipin metabolism and levels. Although cardiolipin levels were unchanged, cardiolipin fatty acid recycling was altered in a manner that could impact mitochondrial protein kinase C δ distribution. Collectively, these changes may account for reduced mitochondrial function. "This paper expands our understanding of how berberine, a widely available herbal supplement, may have a substantial impact on heart health via an untoward impact on heart mitochondrial function," says Murphy. This paper is available for free download through March 16.

Safety of Mono- and Di-Glycerides of Fatty Acids as a Food Additive in the EU

The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re-evaluating the safety of mono- and di-glycerides of fatty acids (E 471) when used as a food additive. The Panel considered that it is very likely that hydrolysis of mono- and di-glycerides of fatty acids by lipases in the gastrointestinal tract would occur, resulting in the release of glycerol and fatty acids. Glycerol (E 422) and fatty acids (E 570) have been re-evaluated and the Panel concluded that there was no safety concern regarding their use as food additives. Toxicological studies with mono- and di-glycerides rich in unsaturated fatty acids were considered for the re-evaluation of E 471. No evidence for adverse effects was reported in short-term, subchronic studies, chronic, reproductive and developmental toxicity studies. Neither carcinogenic potential nor a promotion effect in initiation/promotion was reported. The available studies did not raise any concern with regard to genotoxicity. The refined estimates were based on 31 out of 84 food categories in which E 471 is authorised. The Panel noted that the contribution of E 471 represented at the mean only 0.8–3.5% of the recommended daily fat intake. Based on the approach described in the conceptual framework for the risk assessment of certain food additives re-evaluated under Commission Regulation (EU) No 257/2010 and taking into account the considerations mentioned above, the Panel concluded that there was no need for a numerical acceptable daily intake (ADI) and that the food additive mono- and di-glycerides of fatty acids (E 471) was of no safety concern at the reported uses and use levels. The Panel recommended some modifications of the EU specifications for E 471.
