| Quality of cloudy organic apple juice processed by rack-and-frame press (RFP), water press (WP) or belt press (BP) was evaluated in terms of sensory properties and instrumentally measured colour, content of ascorbic acid (AsA), total soluble solids (TSS), titratable acidity (TA), polyphenols and total antioxidant capacity (TAC). ‘Cortland’, ‘Krista’, ‘Krameri tuvi~oun’ and ‘Talvenauding’ apples from Estonia were separately processed into juice by RFP, WP and BP. Juice was pasteurized at 85 �C. Pressing methods had a significant effect on juice quality. RFP-juices had the lowest TAC and content of health-beneficial polyphenols (chlorogenic acid, (�) epicatechin, (þ)catechin, procyanidin B2). BP-juices had the highest content of these polyphenols,... |

| The main activity was related to the description of qualitative data on commonly consumed fruit (strawberry, plum, apple) and vegetables (tomato and sweet bell pepper) along some processing chains (jam, juices and dried products), pointing out the role of different sources of variability, such as the type of cultivation (Conventional, CONV or Organic, ORG), the different cultivars, the sampling year, and the type of processing. A particular attention has been paid on the type of processing, where the use of innovative plant was performed, in comparison with traditional or home-made processing typologies. This for the need, especially for local and small farmers, of small and simple plants to process agricultural products, in order to add value for their... |

| Plums contain high levels of hydroxycinnamates (neo-chlorogenic acid, Neo-CGA), anthocyanins (ATH) and ascorbic acid. The drying process influences their phytochemical content and plum cultivars are known to have different phytochemical retention after drying, but little data exists regarding to possible differences between conventional (CONV) and organic (ORG) plums. The aim of this study was to evaluate the phytochemical content in three different CONV and ORG plum cultivars (Jubileum, Reeves and Victoria) after freeze drying (FD), conventional oven drying (OD) and solar drying (SD). The three cultivars responded differently to the methods of drying. Notably, Jubileum decreased its ATH mostly when subjected to OD while its Neo-CGA content was mostly... |

| The present work studied the effect of the year of harvest, the genotype and the cultivation method on the nutritional quality and the allergen content of three plum cultivars. The common quality parameters and the phytochemical content strongly varied with the year and the cultivar, while the system of cultivation had a minor influence. In particular, ascorbic acid greatly decreased in 2016 compared to 2015, while polyphenols were higher in 2016. The health-promoting compounds, and particularly phenolics, were significantly correlated with the antioxidant capacity. Finally, the allergen content was strongly dependent on the content of flavan-3-ols, suggesting that this class of phenolics is determinant in influencing the allergen content in plums.... |
