Organic hempseed oil from the retail market: chemical profiling and multivariate analysis for label information assessment

Abstract

PurposeHempseed oil is a valuable emerging food product with recognized health positivity due to its composition. The paper aims to propose a multi-methodological chemical profiling of nine organic hempseed oil samples (different brands and prices) from the retail market, followed by multivariate data analysis.Design/methodology/approachFatty acids, tocopherols, squalene, total carotenoids content, phenolic compounds, total phenolic content and anti-radical activity (DPPH• and ABTS•+ assays) were determined through chromatographic and spectrophotometric techniques. Multivariate (explorative and discriminant) analyses were applied to the profiling results to classify samples according to information claimed on the label, i.e. geographical origin (EU vs. non-EU), extraction procedure (cold-pressed vs. not cold-pressed) and price (lower or higher than 10 € per 250 mL).FindingsThe chemical analysis confirmed the 3 to 1 ?-6:?-3 ratio and the excellent content in antioxidant species. However, no specific trend of results can be stressed. PCA (after variables selection) highlighted a natural grouping of samples, so three discriminant analyses were performed: kNN, Naïve Bayes and LDA. The best classification efficiency was reached for the extraction procedure verification (93–100% correct classification), followed by geographical origin (83–94%) and prices (81.6–90%).Originality/valueThe integrated approach of chemical profiling coupled with multivariate analyses allowed the assessment of label information of the analyzed organic hempseed oil samples, despite the wide heterogeneity of the selected samples.

Simple and reliable eco‐extraction of bioactive compounds from dark chocolate by Deep Eutectic Solvents. A sustainable study

“…To assess the radical scavenging activity of the conventional and DES extracts were conducted by DPPH and ABTS assay following the methods described by Ciano et al, 2022. The DPPH radical scavenging assay was conducted as follows: 1.5 mL of DPPH reagent was added to 1 mL of polyphenol extract and kept in darkness for 30 min. The absorbance was read at 517 nm in a UV-visible spectrophotometer.…”

“…Total phenolic content by Folin Ciocâlteu assay Total phenolic content (TPC) was conducted for all the DES and conventional extracts according to Ciano et al, 2022. Briefly, 0.5 mL of polyphenolic extract was mixed with 0.25 mL of Folin Ciocâlteu reagent in a 10 mL volumetric flask.…”

Heavy metals, rare earth elements and isotopic fingerprint of Venetian Protected Designation of Origin sparkling wines

“…Subsequently, a variable selection was performed to point out the most informative analytes to differentiate sparkling wine samples from white and red ones (Table 8) F-test and p-value for the categorisation in the three types of samples (red, white and sparkling wines) 8. The thresholds used to select the most informative variables were F-test >3.5 and p-value <0.05 (Ciano et al, 2022;Rapa et al, 2023). According to this process, the most suitable variables were Fe, 87 Sr/ 86 Sr, Eu, Cr, Mn, Hg, Th, Re, Ga, Sm, Zn and Dy.…”

Determinants of behavior towards hemp-based products: an application of the theory of planned behavior

“…The legalization of hemp in the United States offers a unique opportunity for farmers and entrepreneurs to explore hemp-based value-added products. Hemp’s prospects as an agronomically sustainable crop and plant-based, renewable input (Ahmed et al ., 2022; Ely et al ., 2022b; Tripathi and Kumar, 2022) are amplified by its versatility as a food (Adesina et al ., 2020; Ciano et al ., 2022; Pihlanto et al ., 2017), textile and fiber (Bouloc and van der Werf, 2013; Montford and Small, 1999), medicine (Adesina et al ., 2020; Thompson et al ., 1998), polymer alternative (Ahmed et al ., 2022; Filimonova et al ., 2022), and biofuel (Das et al ., 2017). However, the sector faces several barriers, including a lack of information on market potential and consumer interest to guide producers navigating this nascent sector.…”
