Honey is a natural product recognized and appreciated for its nutritional value and therapeutic potential. However, the quality of bee honey is essential because various contaminants can seriously affect consumers’ health. In the experimental part of the work, we analyzed different types of honey (linden, black locust, rapeseed and multifloral honey) and propolis, which were collected from Romanian accredited beekeepers who placed beehives in two areas characterized by different industrial activity: area 1 (A1) is an area with intense industrial activity, with other industries existing nearby, including a refinery, while area 2 (A2) is entirely devoid of industrial activity, but with moderate agricultural activity. A total of 144 samples were collected, twelve samples for each variety of honey, propolis and soil, corresponding to each area analyzed. In addition, seven heavy metals and three pesticides were tested for in the samples collected. Finally, the correlation between the degree of contamination with soil pollutants and the contamination of the bee products harvested from the analyzed areas was studied. Cadmium, lead, copper, zinc and the sum of DDT metabolites exceeded the maximum allowable levels in honey samples, with differences between different types of honey.
Mussels have a particular nutritional value, representing a highly valued food source and thus sought after worldwide. Their meat is a real culinary delicacy, rich in proteins, lipids, carbohydrates, trace elements, enzymes, and vitamins. The seasonal variation of mussels’ biochemical composition has been studied to determine the best harvesting period to capitalize on various biologically active fractions. In this work biochemical determinations have been performed on fresh flesh samples of Mytilus galloprovincialis specimens from the Black Sea coast to study seasonal variations in mussels’ biochemical compounds. An analysis of significant lipid classes and the fatty acid composition of lipid extracts obtained from mussel flesh has also been performed. Since mussels retain pollutants from the marine environment, in parallel, the concentration of heavy metals in the meat of mussels collected for the analysis of the chemical composition was investigated. The impact and risk of heavy metal poisoning due to food consumption of mussels contaminated due to pollution of the marine harvesting area was evaluated by the bio-concentration factor of metals and estimated daily intakes of heavy metals through mussel consumption.
The role that insects will play in a healthier and more sustainable diet has been highlighted in the last years, at the European level. In future, due to environmental concerns and population growth, eating insects might be a solution for many problems. However, populations without the tradition of eating insects are still reluctant in accepting such a food as part of their diet. The present observational study highlights some factors that are influencing the acceptance of insects as food in Romania, in 2022. A number of 496 Romanian adults, 433 women and 63 men, with the mean age 39.3 ± 11 years, completed a validated questionnaire analyzing food behaviors, as well as attitudes and knowledge in relation to insects, including sustainability, nutrition and food safety aspects. Only 6.3% of participants had already eaten insects, while 43.8% claimed their openness to do it in future. Insect-based products were accepted more than insects that can be perceived as such. The most frequent words associated with insects were rather deleterious: disgust, odd, nausea, not to eat, or curiosity. Investigating the factors involved in insect acceptability in Romanians’ diets, we found a statistically significant correlation between openness to eat them and the knowledge about insects as being a valuable, sustainable and safe source of nutrients. Targeted education seems to be an important tool in accepting them as part of future diets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
