“…This study shows that low dose VCO (5%) demonstrates relatively more potent antiinflammatory, anxiolytic and cholinergic properties in SBinduced neurotoxicity in male Wistar rats than in high dose (15%). This might result from some heavy metal constituents in VCO, as reported by Amit et al (2022), which is more pronounced in the higher dose used for this study.…”

The effect of virgin coconut oil (VCO) supplemented diet on sodium benzoate (SB) – induced neurotoxicity in male Wistar rats was investigated. Twenty (20) male Wistar rats weighing 160-180g were divided into four (4) groups: Control which received 1ml of normal saline, SB-treated; received 200 mg/kg b.w, SB + Low Dose VCO-treated (SB + 5% VCO mixed with 95g of rat chow), and SB + High Dose VCO-treated (SB+ 15% VCO mixed with 85g of rat chow). The brain was processed for NRF-2, NF-kB, and acetylcholine esterase (AchE) gene expression levels. Also, the blood sample was processed for assessment of superoxide dismutase (SOD), catalase (CAT), and IL1B levels. One-way ANOVA and Tukey post hoc tests were used to analyze data. SB-treated rats with no intervention showed anxiety-like behavior and impaired memory as depicted by a significant (p<0.0001) increase in anxiety index, increase in brain NF-KB, increase in serum IL1B and increase in AchE gene expression level, reduction in the recognition ratio, decreased spontaneous alternation performance, decreased CAT and SOD levels and decreased NRF-2 expression level when compared to other groups (especially control and SB + 5% VCO). VCO supplemented diet (both 5% and 15%) significantly (p<0.0001) increased the CAT and SOD levels, increased the NRF-2 gene expression level, and significantly (p <0.0001) decreased the IL1-B level. Moreover, 5% VCO significantly (p<0.0001) decreased the anxiety index, decreased AchE and NFkB gene expression levels, increased spontaneous alternation performance, and increased recognition ratio compared to 15% VCO. VCO shows a neuroprotective effect in attenuating cognitive impairment and anxiety-like behavior in SB-induced model by modulating oxidative stress and inflammatory pathways, and also enhancing cholinergic neurotransmission.

Fraudulent practices are the first and foremost concern of food industry, with significant consequences in economy and human’s health. The increasing demand for food has led to food fraud by replacing, mixing, blending, and mislabeling products attempting to increase the profits of producers and companies. Consequently, there was the rise of a multidisciplinary field which encompasses a large number of analytical techniques aiming to trace and authenticate the origins of agricultural products, food and beverages. Among the analytical strategies have been developed for the authentication of geographical origin of foodstuff, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) increasingly dominates the field as a robust, accurate, and highly sensitive technique for determining the inorganic elements in food substances. Inorganic elements are well known for evaluating the nutritional composition of food products while it has been shown that they are considered as possible tracers for authenticating the geographical origin. This is based on the fact that the inorganic component of identical food type originating from different territories varies due to the diversity of matrix composition. The present systematic literature review focusing on gathering the research has been done up-to-date on authenticating the geographical origin of agricultural products and foods by utilizing the ICP-MS technique. The first part of the article is a tutorial about food safety/control and the fundaments of ICP-MS technique, while in the second part the total research review is discussed.

“…Virgin coconut oil is a versatile commodity with a demand from the food, pharmaceutical and cosmetic industries, which brings in the requirement to be able to assess the origin of these oils. Amit et al 184 used HCA, LDA and PCA, to build the models from the data obtained by ICP-MS on 18 elements. Both Principal Component Regression and PLSR were able to predict the origins of coconut oils with a R 2 of 0.999 and low RMSEP values (0.074% and 0.075%, respectively).…”
