For the study, the researchers analyzed 13 plots of organic strawberries and conventional strawberries grown side by side. They found that the organic strawberries contained 10 percent more Vitamin C and [w=antioxidant]antioxidants[/w] than their conventional counterparts. The organic strawberries were smaller on average than conventional berries, but each piece of organic fruit actually contained more dry matter—the meat, if you will, of the berry. The organic berries also had a longer [w]shelf-life[/w].[/en] [cn]美國的一組科學(xué)家通過觀察草莓來探究該觀點到底正確與否。為此，科學(xué)家們研究了13塊同期種植有機草莓和普通草莓的種植地。研究發(fā)現(xiàn)，有機草莓含有的維生素C和抗氧化成分要比普通草莓多10%。雖然有機草莓比較小，但是純果肉卻要比普通草莓多得多，保質(zhì)期也較長。[/cn] [en]And finally, a soil analysis showed that the organic plots contained more microorganisms than conventional [w]acreage[/w]. So, the study adds some scientific evidence to the belief that organic berries are healthier, tastier and more environmentally sound.
