Special Issue Information

Dear Colleagues,

Increasing interest in maintaining and enhancing human health has highlighted the awareness of the nutritional quality of vegetables available to consumers. Vegetables provide vitamins, minerals, dietary fibres and health-promoting bioactive compounds. Increasing intake of vegetables is one of the principal recommendations of dietary guidelines for healthy eating worldwide. Numerous studies have documented the association between the consumption of vegetables and a lower risk of cardiovascular disorders, cancer, and diabetes mellitus. Providing consumers with vegetables of high nutritional quality is a mutual goal for breeding, cultivation, postharvest and processing.

This Special Issue focuses on the nutritional quality and human health of vegetable crops from farm to table tracking through the food industry. The issue will include interdisciplinary studies embracing agriculture with disciplines of biology, chemistry and medicine. Research articles will cover a broad range of vegetable germplasm evaluation, quality improvement by breeding, cultivation and quality regulation, technologies for postharvest storage and processing, modern analytical techniques, nutritional quality standards, metabolism and biotechnology as well as health functions. All types of articles, such as original research, opinions, and reviews are welcome.

Quinoa is known for its high nutritional value and adaptability; however, there is a lack of data about the chemical composition of quinoa produced in Ecuador, especially the Chimborazo ecotype. Our research aims to evaluate the nutritional components of Chimborazo quinoa. This knowledge (chemical composition) can help to improve cultivation and farmers’ understanding. Samples were collected from 49 plots at four altitude ranges (3000–3200; 3201–3300; 3301–3400; 3401–3533) m.a.s.l. Each sample of 2 kg quinoa was cleaned, dried (32 °C/15 h), and stored at −20 °C before analyzing water activity, proximate composition, mineral content, antioxidant activity, and functional compounds. The data were analyzed using ANOVA and mean comparison, Pearson correlation, and principal component analysis. The Chimborazo ecotype shows protein content comparable to or exceeding other global quinoa cultivars. Statistical analysis revealed that altitude had a minimal influence on quinoa’s chemical composition, resulting in overlapping altitude-based clusters. Complex relationships between quinoa variables were identified, which varied with altitude. These findings suggest that cultivation of high-quality quinoa across a range of altitudes is feasible without compromising its intrinsic quality. Moreover, the extensive and diverse results from our study provide a solid foundation for further plant breeding and the development of specialized quinoa varieties. Full article
