Effects of the drying technique on the retention of phytochemicals in conventional and organic plum (Prunus domestica L.) Organic Eprints
Vangdal, Eivind; Picchi, Valentina; Fibiani, Marta; Lo Scalzo, Roberto.
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...

Final report for the CORE Organic Plus funded project “Drying, Juices and Jams of Organic Fruit and Vegetables: what happens to Desired and Non-Desired compounds? FaVOR-DeNonDe” Period covered: 30 March 2015 - 29 March 2018 Organic Eprints
Lo Scalzo, Roberto; Campanelli, Gabriele; Moor, Ulvi; Schwab, Wilfried; Vangdal, Eivind; Kidmose, Ulla; Speranza, G (Tutor).
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...

Impact of year of harvest, genotype and cultivation method on bioactives and Pru d 1 allergen content in plums Organic Eprints
Picchi, V; Lo Scalzo, Roberto; Kurze, E.; Fibiani, M; Vangdal, Eivind; Schwab, Wilfried.
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....

The effect of organic fertilizers and thinning methods on quality parameters and the yield on apple cultivars ‘Aroma’ and ‘Discovery’ in Norway Organic Eprints
Koort, Angela; Vangdal, Eivind.
In Norway, apple growers with the packinghouses are focused in medium size apples for 6-pack consumer packages when it comes to cultivar ‘Aroma’. ‘Aroma’ can have an excessive and uneven fruit set and therefore there is a growing need to find out method to reduce the fruit size of cv. ‘Aroma’. 'Discovery' is rather small-fruited cultivar, hence more even and bigger size fruit is desired. In our study, different thinning methods with two different types of organic fertilizers were used to influence the fruit size and the yield. Our hypothesis was that organic fertilizers provide optimal nutrient ranges during the growing season to cultivars ‘Aroma’ and the ‘Discovery’ and have a positive effect on the yield and quality parameters.
