ThesisItem Open Access Processing qualities of cashewnut in relation to agroecological and phenological factors(Department of Processing Technology, College of Horticulture, Vellanikkara, 2001) Divya Raman, S; KAU; Pushpalatha, P BThe project entitled 'Processing qualities of cashewnuts in relation to agroecological and phenological factors' was carried out in the-Department of Processing Technology, College of Horticulture, Vellanikkara during 1999-2000. ( The study revealed that the variation in agroecological factors modify the processing qualities of cashew nuts. The nuts from southern region were observed to be much bolder and found to possess high shelling percentage, kernel size and kernel grade compared to nuts from northern and central regions. In terms of biochemical constituents of kernels, the nuts of northern region excel than the nuts of southern and central regions. When the processing characters of the nuts of selected cashew varieties collected from four different locations were compared, the variety Madakkathra-I, was observed to be a stable variety. It's nut characters remained almost same in all the agroecological regions. The nuts of varieties Kanaka and Dhana were better when they were grown is southern region where as for the variety K-22-1, northern region was found better. The physical characters of nuts from Alappuzha and Wyanad regions did not vary significantly from that of the nuts from other regions, where as the biochemical constituents, sugars and proteins were very low in them. The kernels of nuts from Alappuzha region registered comparatively low fat content.. Regarding the influence of phases of harvest on processing qualities, the nuts of early and mid phases can be considered as superior. The nuts of the same variety, collected during these two phases were observed to be bolder and kernels in them recorded comparatively high amounts of carbohydrates and proteins and low fat. Analysis of cashew nuts at different maturity levels revealed that all favourable processing .qualities are assembled only in fully matured nuts and nuts at lower maturity levels are significantly inferior. The nut quality was found to differ with size of nuts. The big and medium sized nuts were found to possess good kernel size with high protein and carbohydrate content compared to nuts of smaller size. So varieties with bolder nut size are to be promoted for cultivation. The time of market arrival was found to have negligible influence on quality of nuts. The pest infected nuts were considerably inferior to the non infected nuts. They had lost all the favourable processing qualities. Apart from visual distorti-ons and malformations of such nuts, the kernels in them were found shrunken and discoloured. The important biochemical constituents carbohydrates and proteins were significantly low in them. A spoiled nut can never be improved by processing.ArticleItem Open Access Variation in processing qualities of cashew nuts in relation to damage by insect pests(Kerala Agricultural University, Vellanikara, 2002) Divya Raman, S; Pushpalatha, P B; Narayanankutty, M C; KAUThe study revealed that pest attack by tea mosquito bug and thrips on cashew not only caused considerable reduction in the size of nuts and kernels but also resulted in low white whole recovery, more kernel pieces and rejects. The sugars, carbohydrates and proteins were low in kernels of attacked nuts, while the fat content did not vary significantly.
