Última The effect of processing on chokeberry (Aronia Medik.) polyphenols Organic Eprints Hellström, Jarkko; Rajaniemi, Sirpa; Kivijärvi, Pirjo; Mattila, Pirjo. Chokeberries were processed into jams by mixing them with sucrose, water, pectin and citric acid and then boiled. Two different boiling times(5 min and 15 min) were tested. The phenolic compounds in chokeberries were quite stable during the jam making and 70-75 % of the total phenols were recovered from the processed jams.

Ano: 2007 URL: http://orgprints.org/16007/1/berry9.pdf High variability in anthocyanin contents between different blackcurrant varieties Organic Eprints Hellström, Jarkko; Hietaranta, Tarja; Karhu, Saila; Mattila, Pirjo; Tiirikka, Timo; Veteläinen, Merja. The results confirm that blackcurrant is a good source of anthocyanins. However, remarkable variation in the anthocyanin content between varieties is evident. The anthocyanin profile is always dominated by four major anthocyanins, yet some variation appears in their relative proportions. The high anthocyanin content is usually most desirable in the blackcurrant products and this study shows that the choice of variety may have a great impact on it.

Ano: 2010 URL: http://orgprints.org/18316/1/Hellstrom.pdf pH dependence of antimicrobial activity of berries Organic Eprints Rokka, Susanna; Hellström, Jarkko; Mattila, Pirjo; Marnila, Pertti. We have analyzed phenolic compounds from organically and conventionally grown blackcurrants and strawberries to test the idea if organically grown berries contain a higher amount of health-promoting phenolic compounds. Statistically significant differences between farms were found for almost all compounds. In strawberry, the impact of genotype and environment on the flavonol content was more important than the cultivation practice. The "health quality" from organically grown berries does not differ from those grown conventionally. Tipo: Conference paper, poster, etc. Palavras-chave: Food security; Food quality and human health.
