Solanum betaceum Fruits Waste: A Valuable Source of Bioactive Compounds to Be Used in Foods and Non-Foods Applications

Abstract

The fruit supply chain generates large amounts of waste that are often used as animal feed and in the production of both composts and fertilizers and biogas (anaerobic digestion). Since these types of procedures imply high economic costs related to drying, storage, and transport processes, more efficient and environmentally friendly utilization and recycling of this kind of waste are becoming significant for governments and industries. However, improper waste disposal increases the burden on the environment. Many of these fruit wastes, such as Solanum betaceum fruit waste, viz., peels, seeds, and pomace, could be considered potent bio-resource materials for several applications in the food and non-food industries due to their richness in valuable compounds. The basic composition of Solanum betaceum fruits seed has a high content of protein (20%), fiber (around 25%), sugar (11–20%) and low lipid content (0.4%), while S. betaceum peel has a low content of sugar (2–9%), protein (8–10%) and lipid (0.2–0.8%) and high fiber content (23%). Regarding the phytochemicals, the wastes have a high level of phenolics (0.2–0.6%) and pigments such as anthocyanins (0.06%). The inherent bioactive compounds of waste can be used as natural ingredients for foods, cosmetics, medicines, and the production of packaging materials production. Along this line, the present review covers all possible approaches for the valorization of S. betaceum waste in the food and non-food sectors.

Functional and Antioxidant Evaluation of Two Ecotypes of Control and Grafted Tree Tomato (Solanum betaceum) at Different Altitudes

“…It has also been used as an antioxidant additive in the meat industry and an antinociceptive agent in the pharmaceutical industry [ 5 ]. Despite these uses, fruit residues such as shell, seeds and pomace have been little studied and could have significant potential as valuable bioresources for various industrial applications [ 15 ].…”

Functional Characterization and Toxicity of Pectin from Red Chilto Fruit Waste (Peels)

“…Currently, the cultivation of these native varieties is increasing due to local and national government policies for the sustainable use of biodiversity and in response to the industrial exploitation of this fruit to obtain pulp and juice. This results in the generation of waste such as peels and seeds, which could be used to obtain products of interest in pharmacological, cosmetic, or food industries, promoting a circular economy [ 10 , 11 , 12 , 13 , 14 , 15 ].…”

PLANT PARASITIC NEMATODES ASSOCIATED WITH TREE TOMATO (Solanum betaceum Cav.) IN TLACOLULAN AND XALAPA, VERACRUZ, MEXICO

“…Due to this distribution, it is known by various names such as mountain tomato, tamarillo, chilto, eggplant, and the main producing and exporting countries of this fruit are New Zealand, Portugal, Colombia, Ecuador, and Peru (Prohens et al, 1996;Ramírez and Kallarackal, 2019). This species has gained importance due to its nutraceutical properties, including the amount of polyphenols, flavonoids, carotenoids, anthocyanins, and vitamin C (Diep et al, 2020;Isla et al, 2022;Viera et al, 2022). Although it is not known when it was introduced to Mexico, there are records of specimens collected in the states of Chiapas (1945Chiapas ( -1965, Guanajuato (1897), Jalisco (1886) and Veracruz (1976Veracruz ( -1981 growing between 1,000 and 1,300 masl (Bohs, 1994).…”
