Abstract: The use of essential oils (EOs) and/or vacuum packaging (VP) with meats could increase product shelf-life. However, no studies investigating the effect of EOs and VP on camel meat background microbiota have been conducted previously. The study aimed to analyze the antimicrobial effect of essential oils (EOs) carvacrol (CA), cinnamaldehyde (CI), and thymol (TH) at 1 or 2% plus vacuum packaging (VP) on the growth of spoilage-causing microorganisms in marinated camel meat chunks during storage at 4 and 10 °C. VP is an effective means to control spoilage in unmarinated camel meat (CM) and marinated camel meat (MCM) compared to aerobic packaging (AP). However, after EO addition to MCM, maximum decreases in spoilage-causing microorganisms were observed under AP on day 7. Increasing the temperature from 4 to 10 °C under AP increased the rate of spoilage-causing bacterial growth in CM and MCM however, EOs were more effective at 10 °C. At 10 °C the maximum reductions in total mesophilic plate counts, yeast and molds, mesophilic lactic Acid bacteria, Enterobacteriaceae, and Pseudomonas spp. were 1.2, 1.4, 2.1, 3.1, and 4.8 log CFU/g, respectively. Incorporating EOs at 2% in MCM, held aerobically under temperature abuse conditions, delayed spoilage.

Abstract: To date, no studies have examined the validity of skinfold-based (SF) equations and Bioelectrical Impedance Analysis (BIA) in predicting body fat in children of Middle-Eastern origin. The objective of this study was to examine the predictive validity of previously published SF-based equations and BIA in estimating body fat in 8-10 year-old Lebanese children, and to develop new prediction equations for use in this population group. 158 subjects participated in the study. Percent body fat (% BF) estimates derived from SF-based equations and BIA were compared against the deuterium dilution technique (DDL). Multivariate linear regression analyses were conducted for the development of new prediction equations to estimate %BF using anthropometric variables. Bland-Altman analysis showed that SF-based equations and BIA significantly underestimated %BF as compared to DDL. Mean differences in %BF ranged between 1.3 and 6.5% in boys and 4.5-9.5% in girls. New anthropometry-based equations were proposed for the prediction of %BF in Lebanese pre-pubertal children. Previously published prediction equations underestimated %BF in Lebanese pre-pubertal children. The validity of the new prediction equations developed in this study to estimate %BF in Lebanese children needs to be investigated in future studies.

Abstract: To assess the validity and reliability of the Arabic version of the Household Food Insecurity Access Scale (HFIAS) in rural Lebanon. A cross-sectional study on a s le of households with at least one child aged 0–2 years. In a one-to-one interview, participants completed an adapted Arabic version of the HFIAS. In order to evaluate the validity of the HFIAS, basic sociodemographic information, anthropometric measurements of the mother and child, and dietary intake data of the child were obtained. In order to examine reproducibility, the HFIAS was re-administered after 3 months. Rural Lebanon. Mother and child pairs ( n 150). Factor analysis of HFIAS items revealed two factors: ‘insufficient food quality’ and ‘insufficient food quantity’. Using Pearson's correlation, food insecurity was inversely associated with mother's and father's education levels, number of cars and electrical appliances in the household, income, weight-for-age and length-for-age of the child and the child's dietary adequacy. In contrast, mother's BMI and crowding index were positively associated with food insecurity scores ( P 0·05 for all correlations). Cronbach's α of the scale was 0·91. A moderate correlation was observed between the two administrations of the questionnaire (intra-class correlation = 0·58 P 0·05). Our findings indicated that the adapted Arabic version of the HFIAS is a valid and reliable tool to assess food insecurity in rural Lebanon, lending further evidence to the utility of the HFIAS in assessing food insecurity in culturally erse populations.
