Special Issue Information

Dear Colleagues,

For many centuries, agriculture and agricultural knowledge have been crucial to meeting the growing food resource needs of human societies. From its inception, agriculture has been linked to the need for available quantities of foodstuffs under specific climatic, natural, agrotechnical, and economic conditions, and, on the other hand, to the quality control devices produced by agricultural parents.

This Special Issue of Agriculture (ISSN 2077-0472), ‘Phytochemical Changes in Vegetables and Fruits During Post-Harvest Storage and Processing’, will focus on the development of methods for shaping the quality of fruits and vegetables at every stage of their growth, beginning with the use of genetic engineering methods in seed preparation to control the potential and yield of plants, their development, and harvest, as well as providing means and methods for conscious control during periods of limited disposal. The best practices of currently planned experiments, including those concerning the quality of fruits and vegetables as products in agri-food processing, may lie in their versatility, multifaceted nature, and interdisciplinarity. Another advantage of these experiments is their analytical application, which utilizes high-quality sources, precision, and comprehensive results. In addition to studies expanding experimental research, this Special Issue also seeks reviews, opinions, and summary studies.

This study investigates the changes in mechanically harvested ‘Leccino’ olives stored under cold and room-temperature conditions from harvest up to 23 days of storage during two consecutive seasons. Variations in quality parameters, including maturity index, weight, firmness, and colour, were monitored throughout the storage period. In addition, the phenolic profile of the olives was analysed using HPLC, and the fatty acid composition was determined by GC–MS. These analyses enabled a comparison of changes across different storage durations, seasons, and storage conditions. Results show that fruit ripeness at harvest differed notably between the two seasons. In the second season, the olives displayed a higher maturity index, lower firmness, and lower content of certain individual phenolic compounds, indicating a more advanced stage of ripening compared to that of the previous year. These initial differences strongly influenced the subsequent development of fruit quality and biochemical characteristics during storage. Storage temperature had a significant effect on the quality parameters and metabolism. As expected, olives stored at room temperature lost their firmness and weight more quickly than those stored under cold conditions. The most abundant phenolic in olive fruit, oleuropein, degraded more rapidly at room temperature, resulting in a quicker accumulation of its derivatives. Fatty acids were more stable than phenolic compounds during storage, likely due to their lower susceptibility to enzymatic degradation and oxidative reactions under the tested conditions. While saturated fatty acids remained largely unchanged, a slight increase in unsaturated fatty acids was observed after 23 days of cold storage, possibly as a result of adaptations of the membrane to cold storage conditions.
