ABSTRACT
The primary rules of the organic agriculture are plants production without mineral fertilizers and pesticides. Widely used are natural fertilizers as manure, compost also green manure. For plant protection are used natural insect predators and plants extracts. The sweet red pepper is a good source of vitamin C, flavonoids especially rutin also carotenoids: capsorubin, capsantin, beta-carotene and lutein. Their poignancy red pepper fruits owe alkaloid - capsaicine. A lot of experiments affirmed that fruit and vegetable from organic production contained more antioxidant compounds as flavonols, carotenoids also vitamin C. Because organic vegetables contained more of these compounds in comparison to conventional one, therefore it could be suspect that pickled vegetables, nevertheless processing will contain more antioxidant compounds. A very important aspect it seemed the fact of analysis the way of bioactive compounds changes in pickled red pepper in comparison to fresh one. For experiment were use two cultivar of sweet red pepper (Ożarowska and Roberta) from organic and conventional cultivation. The chemical analysis of dry matter, witamin C, flavonols and carotenoids were carried out. The next step of analysis was processing (make of pickled red pepper). After four month sensory and chemical analysis were carried out. The obtained results of fresh red pepper showed that organic fruits contained more vitamin C, rutin, lutein also dry matter. Conventional pepper contained more beta-carotene and lycopene. The pickled organic red pepper contained more vitamin C and lutein in comparison to conventional one. After pickling process the loss of vitamin C, lycopene, beta-carotene and dry matter were observed in fruits from both cultivation systems. The sensory analysis show that organic pickled red pepper has a higher notes of spices and pepper odour also acetic, spices, sweet and pepper flavour. Organic pickled red pepper has also the significantly higher the total quality of fruits. Additionally has been observed the strong correlation between pungent flavour and flavonols content, the total quality and sugar to acids ratio for organic pickled red pepper also the total quality and dry matter content for conventional one.
