Effect of the Strawberry Genotype, Cultivation and Processing on the Fra a 1 Allergen Content Organic Eprints
Kurze, E.; Kock, V.; Lo Scalzo, R; Olbricht, K.; Schwab, Wilfried.
Birch pollen allergic patients show cross-reactivity to vegetables and fruits, including strawberries (Fragaria × ananassa). The objective of this study was to quantify the level of the Fra a 1 protein, a Bet v 1-homologous protein in strawberry fruits by a newly developed ELISA, and determine the effect of genotype, cultivation and food processing on the allergen amount. An indirect competitive ELISA using a specific polyclonal anti-Fra a 1.02 antibody was established and revealed high variability in Fra a 1 levels within 20 different genotypes ranging from 0.67 to 3.97 μg/g fresh weight. Mature fruits of red-, white- and yellow-fruited strawberry cultivars showed similar Fra a 1 concentrations. Compared to fresh strawberries, oven and solar-dried...

Effect of tomato variety, cultivation, climate and processing on Sola l 4, an allergen from Solanum lycopersicum Organic Eprints
Kurze, E.; Lo Scalzo, R; Campanelli, G.; Schwab, Wilfried.
Tomatoes (Solanum lycopersicum) are one of the most consumed vegetables worldwide. However, tomato allergies in patients suffering from birch pollen allergy occur frequently. Due to highly similar protein structures of the tomato allergen Sola l 4 and the major birch pollen allergen Bet v 1, patients cross-react with allergenic proteins from tomato as well as other fruits or vegetables. The aim of this study was to quantify Sola l 4 in various tomatoes differing in color, size and shape for identification of varieties with a reduced allergen level. Therefore, an indirect competitive ELISA using a specific polyclonal Sola l 4 antibody was developed. In addition, two varieties, both cultivated either conventionally or organically and furthermore...

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....

Konfitüren, Säfte und Trocknung biologisch angebauter Lebensmittel: Was geschieht mit Allergenen während der Verarbeitung? Organic Eprints
Kurze, E.; Schwab, Wilfried.
Food allergy is an increasing health problem, whereby plant allergens are one of the major source eliciting allergenic reactions. Ninety percent of birch pollen allergic patients develop intolerances to fruits and vegetables. Antibodies against Bet v 1, the major birch pollen allergen, cross-react with Bet v 1-homolog proteins present in a variety of fruits and vegetables. Bet v 1 and Bet v 1-homolog proteins belong to the family 10 of pathogenesis-related proteins (PR-10). In plants PR-10 proteins are induced in various stress conditions, e.g. pathogen attack, wounding or environmental factors. The amount of allergens is influenced by pre- and post-harvesting factors, such as cultivar, organic or conventional cultivation and storage conditions as well...
