The present study determines the characteristics of bleaching and beating of annual plants and agricultural waste, which constitute important raw material potential for the pulp and paper industry in Turkey. It also examines the effects of this process on several paper properties. Firstly, chemical contents are determined for each raw material and then evaluated for use in the pulp and paper industry. All raw materials studied are found to be suitable for use in the pulp and paper industry, according to the determined chemical content. Secondly, pulp with different properties is obtained and subsequently pretreated with the enzyme xylanase. It …

The aim of this study was to compare the effects of roasting and enzyme pretreatments on the yield and quality of cold-pressed oils obtained from 3 poppy seed varieties (Ofis 3 (blue), Ofis 4 (yellow), Ofis 8 (white)). The oil recovery range was 21.89%-38.36% with cold pressing. The oily cakes (meal) contained 42-168 g/kg oil and 113-166.3 g/kg moisture after the cold pressing. Physicochemical and quality tests were conducted to evaluate and compare the efficacy of the pretreatments. Furthermore, fatty acid, sterol, and tocopherol compositions were determined. Oil recovery was enhanced by enzyme treatment in Ofis 3 (28.31%) and Ofis …
