The paper discusses the influence of the addition of freeze-dried tomatoes on the chemical composition and selected physical properties of extruded corn snacks. Corn grits were replaced with dried tomatoes in the amount from 5 to 30% of corn mass. The total lycopene and phenolic content, the scavenging ability and the ferric reducing antioxidant power were determined along with the content of neochlorogenic,...
The aim of the research was to assess the quality of 21 soil-grown determinate tomato varieties.All of them are recommended for crop production in Polish climate conditions. The colour of fruitsand the contents of dry mass, extract, total sugars, vitamin C and carotenoids were analysed. It is not feasible to select one single variety with high levels of all the studied parameters. The varieties with...
The purpose of this investigation was to evaluate the usefulness for freezing of new broccoli varieties. The evaluation was based on chemical composition of fresh and frozen broccoli stored for three months. The study was conducted on seven broccoli varieties, namely: SVR 97, SVR 99, SVR 1002, SVR 1017, Ironman, Beneforte and Bellaverde. The broccoli were obtained directly from the producer (Moszna,...
The studied material were the fruits of 7 wild species: dog rose (Rosa canina L.), blackberry (Rubus caesius L.), elderberry (Sambucus nigra L.), blueberry (Vaccinium myrtillus L.), blackthorn (Prunus spinosa L.), rowan (Sorbus aucuparia L.) and wild strawberry (Fragaria vesca L.). The fruits were subjected to an antioxidant activity assay (AA). Two methods were used: FRAP and ABTS. The fruit samples...
