AU - Stewart, HE AU - Farkas, BE AU - Blankenship, SM AU - Boyette, MD T2 - INTERNATIONAL JOURNAL OF FOOD PROPERTIES AB - Abstract Physical and thermal properties of three commonly grown sweetpotato cultivars were evaluated. Density, specific heat, thermal conductivity, and respiration rate were determined for ‘Beauregard’, ‘Hernandez’, and ‘Jewel’ varieties. In addition, respiration heat and thermal diffusivity were calculated for these cultivars. Uncured and cured sweet potato were evaluated and held under controlled storage conditions. Postharvest treatment and cultivar differences had minor effects on the density, specific heat, and thermal conductivity of sweetpotato. Respiration rate of the uncured and cured sweetpotato was evaluated at four temperatures: 15, 20, 25, and 30°C. Respiration rate and respiration heat for the cured sweetpotato was less than that of the uncured sweet potatoes. Results from this study will be instrumental in the design and optimization of sweetpotato curing and storage facilities and in the development of new quality indicators.

No mycelial growth was observed on russetted areas of the cuticle that are considered impermeable. Ursolic acid and n-alkanes were the most prominent components of the epicuticular waxes of the cultivars or selections evaluated. Although there were differences in the relative proportions of these compounds among the cultivars, the differences were not related to the severity of sooty blotch. Peltaster fructicola and Leptodontidium elatius were grown on compounds that comprise the epicuticular wax of the fruit to determine if one or more of these were needed for growth. The fungi did not grow on any of the five major components of the epicuticular wax unless dilute apple juice was included. Scanning electron microscopy studies showed that mycelia of P. fructicola grew on the surface of the wax and did not appear to degrade it. Our studies support the hypothesis that P. fructicola and L. elatius fungi are epiphytes and obtain their nutrients not from components of the cuticle, but more likely from fruit leachates.
