Special Issue Information

Dear Colleagues,

Nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) are pivotal analytical methods extensively employed in food science applications. By combining their capabilities, they offer complementary insights, facilitating a comprehensive analysis of food samples. In the realm of food science, NMR and MS are indispensable tools for evaluating quality, detecting adulterants and identifying contaminants such as pesticides and mycotoxins. Their versatility and sensitivity make them invaluable for studying various aspects of food, including composition, safety and functionality, thereby significantly contributing to the enhancement of food products. Furthermore, NMR and MS are crucial for investigating the effects of preservation methods on food quality, monitoring reactions, identifying degradation products and assessing the impact of storage conditions. These techniques are instrumental and non-destructive tools in flavor and aroma analysis, enabling the identification and quantification of volatile compounds that influence sensory attributes. Moreover, they support metabolomics studies, facilitating the analysis of metabolic profiles in food samples to understand composition, biochemical pathways and health implications. Their multifaceted applications underscore their importance in food science and its various research areas.

Chili peppers (Capsicum annuum L.) are economically valuable crops belonging to the Solanaceae family and are popular worldwide because of their unique spiciness and flavor. In this study, differences in the metabolomes of landrace (Subicho) and disease-resistant pepper cultivars (Bulkala and Kaltanbaksa) widely grown in Korea are investigated using a 1H NMR-based metabolomics approach. Specific metabolites were abundant in the pericarp (GABA, fructose, and glutamine) and placenta (glucose, asparagine, arginine, and capsaicin), highlighting the distinct physiological and functional roles of these components. Both the pericarp and placenta of disease-resistant pepper cultivars contained higher levels of sucrose and hexoses and lower levels of alanine, proline, and threonine than the traditional landrace cultivar. These metabolic differences are linked to enhanced stress tolerance and the activation of defense pathways, imbuing these cultivars with improved resistance characteristics. The present study provides fundamental insights into the metabolic basis of disease resistance in chili peppers, emphasizing the importance of multi-resistant varieties to ensure sustainable agriculture and food security. These resistant varieties ensure a stable supply of high-quality peppers, contributing to safer and more sustainable food production systems. Full article
