“…Another reason may be that differences in the expression levels of sugar metabolizing genes among the genotypes may influence the sugar content in the grape berries. 20 Our previous studies showed lower invertase activity in muscadine genotypes compared with FHB and bunch grape cultivars, 21 confirming this observation.…”

Sugar content and composition of the bunch grape (Vitis vinifera) berry and its hybrids has been investigated extensively while limited information exists on the sugar content and composition of muscadine (Vitis rotundifolia) grapes. In this study, selected commercial grape cultivars belonging to muscadine, bunch, and Florida hybrid bunch market types were studied for content and composition of sugars in ripe berries for 2 consecutive years. Berry sugars were analyzed by high-performance liquid chromatography (HPLC), and the amount of sucrose, glucose, and fructose was quantified based on their peak area. Glucose and fructose were the predominant sugars in berries of bunch and Florida hybrid bunch grape genotypes and were present in almost equal amounts. In contrast, the muscadine berry contained sucrose, glucose, and fructose. Sucrose was not detected in bunch and Florida hybrid bunch grape genotypes. Glucose constituted 46.0%-53.0% of the total berry sugars while fructose ranged between 47.0% and 53.0% among the bunch cultivars studied. In Florida hybrid bunch cultivars, the glucose percentage varied from 39.0% to 56.0% while fructose varied from 44.0% to 53.0%. In muscadine genotypes, sucrose constituted 17.0%-47.0%, glucose 27.0%-39.0%, and fructose 26.0%-47.0%. The proportion of glucose and fructose was almost equal in all three categories while the level of sucrose varied widely among the muscadine genotypes indicating that variable sucrose accumulation and/or hydrolysis may influence the berry sucrose content among the grape genotypes.

“…Sugar accumulation is an important event in the berry-ripening physiology of grapevine, and is essential for superior enological characteristics and product value. 1 Also sugar content in grape berries is the major factor determining fruit quality. Sugar is synthesized in leaves as a result of photosynthesis and imported via the phloem into the berry in the form of sucrose.…”

“…In addition, metabolic activity continues as a result of fruit ripening, which leads to converting carbohydrates and organic acids into sugars to be used in several metabolic processes [58]. In our study, the increase of SSC in grapes with treatments and control grapes was due to conversion of sucrose into glucose and fructose [59]. Now, comparing with control grape, the NC-BCO-C and the NC-EOt-C multisystem showed lower values of SSC.…”

In developing countries, the incidence of postharvest losses reduces the quantity and quality of food for human consumption and causes an economical damage along the food chain, especially, for primary producers. In this study, a multisystem coating (NC-EOt-C) based on pullulan and polymeric nanocapsules containing EO of Thymus vulgaris L. (EOt) was applied to increase the shelf life of table grapes (Vitis vinifera L.). The major components of EOt, chemically characterized by GC-MS, were o-cymene (32.68%), thymol (31.90%), and γ-terpinene (15.69%). The NC-EOt were prepared by nanoprecipitation and showed a particle mean size of 153.9 nm, a polydispersity index of 0.186, a zeta potential of −4.11 mV, and an encapsulation efficiency of 52.81%. The antioxidant capacity (DPPH and ABTS + methods) of EOt was maintained, or even improved, after its incorporation into NC. The shelf life study showed that grapes having the NC-EOt-C multisystem maintained their characteristics of color, firmness, TA, and SSC for longer time than those without the multisystem. NC-EOt-C multisystem acted as a barrier which reduced the metabolism of fruits. In addition, the compounds of EOt with antimicrobial activity avoided microorganism growth, while those with antioxidant activity reduced the oxidative stress induced during postharvest of grapes. Additionally, the polymeric structure of NC prevented the rapid evaporation of volatile compounds of EOt, increasing then their residence time on the fruit. Our study demonstrated that NC-EOt-C multisystem can be a viable alternative to preserve horticultural products for longer storage periods.
