Hubungan antara Sifat Fisik dan Gelombang Ultrasonik Durian Utuh dengan Sifat Fisiko Kimia Daging Durian

Abstract

Cntrasonic method was utilized for the measurement of attenuation of ultrasonic wave through duriun. Thirty six .durians . consits of ripe and unripe fruit harvested from Ciherang Bogor were tested. The whole durians were subjected to attenuation and 1 physical properties measurement. Following this procedure, all durians were opened to measure firmness and dotal soluble solid 1 (TSS) of the pulp. The data set were analyzed statiscally for the relationship between ultrasonic (Mo)parameter, firmness and TSS. There were significant relationship between Mo and firmness ( r = 0.76), and Mo and TSS (r = - 0.71). There a was also a significant 1 relationship between ultrasonic parameter combined with mass (r = 0.84) and the firmness of durian'spulp. The equation model to determine firmness parameter was F=(2.8x l u J ) m' nMo'
