“…Physalis (Physalis peruviana L.) is cultivated in several regions of the world (Scher et al, 2014) and is easily propagated and dispersed (Njoroge et al, 2004). Its fruits contain phenolic compounds, polyphenols, flavonoids, carotenoids, steroids, physalins, vitamins, and minerals (Puente et al 2011;Machado et al, 2019;Mier-Giraldo et al, 2017;Marchioretto et al, 2020).…”

Cultivation of small fruits such as blackberry, raspberry, blueberry, strawberry, and physalis is rapidly growing in Brazil, mainly due to small producers who seek income diversification. The aim of this study was to evaluate the effect of foliar application of different doses of chitosan on the physicochemical properties of Physalis peruviana L. Two experiments were conducted: i) field (FE); and ii) greenhouse (GE). Four doses of chitosan (0.1, 0.2, 0.3, and 0.4 L 100L-1) and a control were used as treatments. We evaluated fruit diameter (FD), fruit length (FL), calyx length (CL), and calyx diameter (CD) - mm; fruit mass - g; soluble solids content (SS) - °Brix; titratable acidity (TA) - % of citric acid; SS/TA ratio; and fruit firmness - N. Foliar application of chitosan to field-grown physalis plants significantly increased fruit mass, length, and diameter, as well as fruit SS and TA content. However, in a protected environment, the application of chitosan had less effect on the properties evaluated. Fruit firmness was not affected by chitosan application. Negative correlations (P<0.001) between fruit mass and firmness (r=-0.57) and SS/TA ratio (r=-0.61) were observed. SS/TA ratio was also negatively correlated with TA (r=-0.82), FL(r=-0.61), and FD (r=-0.68). High and significant correlations were observed between fruit mass and TA, FL, and FD. Foliar application of chitosan has a positive effect on both agronomic and chemical properties and can be an excellent alternative natural fertilizer for physalis plants when applied in doses up to 0.2 L 100 L-1.

“…The calyx of P. peruviana is an inedible byproduct and represents 5% of the weight of fresh fruit (Ballesteros-Vivas et al, 2019). Colombia is the largest producer in the world, followed by South Africa (Bazana et al, 2019), countries that export fruit to other countries such as the Netherlands, the United Kingdom, Germany, Belgium, and the United States (Marchioretto et al, 2020;M.-L. Olivares-Tenorio et al, 2016). In Colombia, the fruit of P. peruviana has a fifth place in export fruits (Minagricultura, 2019).…”

Physalis peruviana is marketed without its calyx, which generates byproducts and a decrease in the shelf life of these fruits. The aim of this study was to evaluate the effect of edible pectin-coatings reinforced with nanocellulose from calyx on the physical-chemical and physiological parameters of P. peruviana fruits during refrigerated storage (5 C) for ten days. The nanocellulose extraction was carried out using a combined extraction method (chemical procedures and ultrasound radiation). The characterization of the fibers showed that the maximum degradation temperatures ranged between 300 and 311 C. The SEM analysis revealed the presence of fibers after the chemical treatment. The removal of lignin and hemicellulose was validated using Fourier Transform Infra Red (FTIR) spectroscopy. The results showed that the fruits treated with pectin and pectin reinforced with nanocellulose at 0.5 % (w/w) had an adequate visual appearance and showed a minor color change (ΔE of 19.04 and 21.04, respectively) and the highest retention of L* during storage. Although the addition of nanocellulose at 0.5% presented the lowest respiratory rate (29.60 mgCO 2 /kg h), the treatment with pectin offered the least weight loss and showed the highest firmness retention at the end of storage. Thus, the edible pectin-coating may be useful for improving the postharvest quality and storage life of fresh P. peruviana fruit. Nanocellulose from P. peruviana calyces can be used under the concept of a circular economy; although, its use as a reinforcement of pectin showed some limitations.
