Determination of some physical, chemical properties of loquat cultivars (eriobotrya japonica L.) and possibilities of their being processed into marmalade, nectar and canned fruit

ABSTRACT DETERMINATION OF SOME PHYSICAL, CHEMICAL PROPERTIES OF LOQUAT CULTIVARS {Eriohotryajaponica L.) AND POSSIBILTUES OF THEIR BEING PROCESSED INTO MARMALADE, NECTAR AND CANNED FRUIT Ayhan TOPUZ M.Sc. in Food Engineering Adviser: Asst.Prof. Dr. Feramuz ÖZDEMİR July, 1998, 92 Pages In this study, determining some physical and chemical properties of Hafif Çukurgöbek, Uzun Çukurgöbek, Akko XJH, Gold Nugget, Yuvarlak Çukurgöbek, Armudi and Tanaka cultivars of loquat it was also investigated if the fruit can be processed into marmalade, nectar and canned fruit. According to obtained results Hafif Çukurgöbek, Akko XIII and Gold Nugget cultivars are more suitable to process into marmalade and nectar than other cultivars. Tanaka, Gold Nugget and Akko XHI cultivars of loquat are also determined more suitable to process into canned fruit than others.
