The impact of cultivar and production system was studied over two years on organoleptic and nutritional characteristics of apple fruits and then, on purees processed with both conventional convection cooking under vacuum and fast innovative microwave cooking. The main factors affecting the content and composition of sugars, organic acids, volatiles, polyphenols, and fibre were in the decreasing order, cultivar, year, and production system. Regarding processing, the fast innovative microwave cooking led to puree with a higher viscosity but with a lower polyphenol content compared to the convection cooking.

- Genomic selection (GS) is a breeding method that uses comprehensive genetic data to improve genetic progress in crops and livestock, and this study explores its application in enhancing postharvest quality of apricots.
- The research involved a specific population of apricot trees, assessing 153 individuals for various fruit traits over two years under different climates, finding that certain genomic models, particularly RR-BLUP, provided the most accurate predictions of traits like ethylene production.
- The study reveals key insights into the genetics of apricot quality, suggesting that integrating this genetic knowledge can optimize breeding strategies, particularly for traits influenced by significant genetic factors.
The changes of texture and cell wall characteristics of apricot were investigated in ten clones at two maturity stages. Fruit firmness, cell wall composition and enzyme activity of three apricot flesh zones were analysed. The AIS (alcohol-insoluble solids) were characterised by high amounts of uronic acid (179-300 mg g AIS) and relatively high amounts of cellulosic glucose (118-214 mg g AIS).

- The research manipulates enzymes related to ascorbate (vitamin C) in tomato fruit cells, which alters the balance between its different forms and results in various phenotypes.
- A systems biology approach analyzes how changes in the transcriptome, proteome, and metabolites differ among RNAi lines that target specific ascorbate-related enzymes, revealing an inversion in gene expression patterns.
- Notably, the study finds that gene expression doesn’t always match protein levels, yet certain proteins and metabolites show correlations to enzyme activity, highlighting complex signaling responses influenced by ascorbate levels.
Apricot polyphenols and carotenoids were monitored after industrial and domestic cooking, and after 2months of storage for industrial processing. The main apricot polyphenols were flavan-3-ols, flavan-3-ol monomers and oligomers, with an average degree of polymerization between 4.7 and 10.
