“…Percentages of correct classification were high since none of the Pa samples was misclassified using the geographical origin as the grouping variable (Figure 6). Therefore, as with oil palm, rice, and olive, lipid profiling may be an effective chemometric method to discriminate Pa origins 28,51,52 . Further, both environmental and genetic factors may contribute to the observed differences in fruit lipid composition between Pa populations.…”

A recent study reported the role of geographical distribution over the genetic structure in Pa populations 53 ; which may also influence the biochemical variations of lipids.…”

BackgroundThe palm tribe Phytelepheae (vegetable ivory palms) produces oleaginous fruits traditionally consumed by indigenous and local communities. We therefore analyzed the oil content as well as fatty acid (FA), carotenoid, and tocochromanol composition of fruits collected from 35 palm trees in their natural habitats, namely Phytelephas aequatorialis (Pa, n = 28), Aphandra natalia (An, n = 5), and Ammandra decasperma (Ad, n = 2).ResultsAverage mesocarp oil content was high in Pa and An (ca. 30% dry mass [DM]) but not in Ad (10% DM). However, significant differences in fruit oil content between Pa populations were observed. Further, FA composition varied significantly among species and between Pa populations. The main FAs were oleic (17%–73%), palmitic (17%–41%), linoleic (2%–32%), and stearic (3%–13%) acids. The mesocarp oil of some Pa palms contained a high amount (>20%) of linoleic acid and a low amount of saturated FA (<25%). A high variability of total tocochromanol (89, 122, and 145 mg/kg oil for Pa, An, and Ad, respectively) and total carotenoids (96, 42, and 157 mg/kg for Pa, An, and Ad, respectively) content was also found.ConclusionThe fruits of the neglected Phytelepheae palms may represent a valuable source of lipids, including the essential FA linoleic acid and lipid‐soluble vitamins, and help to diversify dietary lipid sources in Ecuadorian geographical areas where there is a high rate of saturated fat consumption.

“…Adulteration and mislabelling is commonplace due to demand for particular varieties and origins. Wadood 236 and team have collated the latest studies into rice authenticity utilising a variety of analytical and statistical methodologies: ICP-MS, ICP-OES and IRMS are most commonly employed for analysis and PCA, HCA (Hierarchical Cluster Analysis), ANN, KNN (K-nearest neighbour), LDA, PLS-DA, SIMCA, and SVM. The collated information provides a useful summary to the current progress in this field.…”

Laser-induced breakdown spectroscopy (LIBS) is an atomic-emission spectroscopy technique that employs a focused laser beam to produce microplasma. Although LIBS was designed for applications in the field of materials science, it has lately been proposed as a method for the compositional analysis of agricultural goods. We deployed commercial handheld LIBS equipment to illustrate the performance of this promising optical technology in the context of food authentication, as the growing incidence of food fraud necessitates the development of novel portable methods for detection. We focused on regional agricultural commodities such as European Alpine-style cheeses, coffee, spices, balsamic vinegar, and vanilla extracts. Liquid examples, including seven balsamic vinegar products and six representatives of vanilla extract, were measured on a nitrocellulose membrane. No sample preparation was required for solid foods, which consisted of seven brands of coffee beans, sixteen varieties of Alpine-style cheeses, and eight different spices. The pre-processed and standardized LIBS spectra were used to train and test the elastic net-regularized multinomial classifier. The performance of the portable and benchtop LIBS systems was compared and described. The results indicate that field-deployable, portable LIBS devices provide a robust, accurate, and simple-to-use platform for agricultural product verification that requires minimal sample preparation, if any.
