Discover the ""Nutritional and Safety on the tip of the tongue"" within the pages. "Method development and risk assessment of pesticides, and sour flavor evaluation of fruit in China" is an important exploration into the profound impact for evaluating the nutritional quality and monitoring safety of fruits in Chinese. From nutritional quality to safety, this book analyzes the grading standards of sour flavor for apple, the optimization of analysis technology for pesticides in fruits, and risk monitoring assessment. It will provide a strong scientific support for evaluating the nutritional quality and monitoring safety of fruits in Chinese. Flavor is an important component of fruit quality. Organic acids are the main flavor compounds in fruit. By evaluating 10 important sour flavor indices from 106 apple cultivars, including six organic acids, total organic acids, titratable acid, acidity value and pH value, the significant relationships between these indices were identified. And then, accurate predictive models were established. With precise evaluation indices and groundbreaking grading system, discover the science behind apple sour flavor is the essential for horticulturists and food scientists. From method development to risk assessment of multiple pesticide residues in fruits, this book offered a one-stop solution for fruit safety assessment. This provides an indispensable reference for researchers in the field of food safety.
