RIVERA-PONCE, Edgar Adrián et al. Commercial potential of fruits from albus varietal groups of chayote. Rev. Mex. Cienc. Agríc [online]. 2025, vol.16, n.7, e3862.  Epub 13-Fev-2026. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v16i7.3862.

Mexico has the greatest variability of chayote (Sechium edule Jacq. Sw.) fruits. Nevertheless, there are no reports on postharvest treatments for albus-type white chayotes. The objective was to evaluate different postharvest treatments in the albus varietal groups: a. minor, a. levis, a. dulcis, a. spinosum, and a. levis gigante, harvested in Huatusco, Veracruz, Mexico. To do this, the fruits were stored at 12 ±1 °C and 90 ±5% RH for seven days and then kept at 18 ±1 °C and 60 ±5% RH for evaluation. The treatments were wax, plastic film, citric acid and ascorbic acid, alone or in combination. Weight loss, commercial quality, enzyme activity, membrane permeability, and phenol content were determined. It was observed that the albus-type fruits are sensitive to epicarp darkening, weight loss, viviparity, and incidence of fungi, with a shelf life of between 1 and 6 days. The use of wax coating and plastic films, individual or combined with organic acids, reduced weight losses and the enzymatic activity of polyphenol oxidase (PPO) and peroxidase (POD), increasing the shelf life of the fruits by 6 to 12 days.
