Physico-chemical and anthocyanin profiling of Morus spp. cultivars grown in Tamil Nadu

Abstract

The Physico-chemical and anthocyanin profile of different mulberry fruit cultivars, namely V, S13, MR2 and S36 grown in different regions of Tamil Nadu were investigated. The fruit properties of the cultivars varied based on soil type and cultivation location. The MR2 variety cultivated in Palladam area recorded the highest juice yield (532.6 g/1000 g fresh weight). The fruits of mulberry cultivars commonly grown in Tamil Nadu exhibited black to purple colour. The colour values of the fresh fruits measured in term of L*, a*, b* values indicated that the redness and blueness values between 14.73 to 24.26, 8.02 to 23.01 and-4.15 to-12.41, respectively. The average weight of single mulberry fruit ranged from 1.62 g to 1.84 g and the moisture content was between 75.50 to 88.00%. The compositions of the samples were 5.04 to 5.28 pH, total soluble solids (TSS) between 9.2oBrix to 13.6 o Brix. Reducing sugars content was 7.02 to 10.07% per 100g fresh weigh. The total monomeric anthocyanin content, determined using the pH-differential method was in the range of 179.51 to 271.35 mg cyanidin-3-3-O-glucoside l-1 of fresh juice.
