“…Costa (2012) also found that the exposure of papaya fruits to ozone did not change vitamin C contents. The average vitamin C value in this study was 82 g 100g -1 (Table 3), which is close to values obtained by other studies in literature (REIS et al, 2015a, b;IAMJUD et al, 2016). In studies of pineapple, banana, papaya and grapes exposed to ozone, vitamin C content decreased (ALOTHMAN et al, 2010;YEOH et al, 2014).…”

This study investigated the effect of ozone on papaya postharvest conservation, aiming at controlling anthracnose and increasing fruit shelf life. The experiment was conducted at the Laboratory of Product Technology, Federal University of Amazonas, Manaus-AM. Fruits were treated with 0; 0.6; 1.5 and 3.3 ppm ozone and commercial fungicide. They were then stored at room temperature (27 ± 2 °C and 65 ± 5% RH). Incidence, severity, number and size of anthracnose lesions were determined, as well as postharvest quality by assessing shelf life; accumulated and daily fresh mass loss (%), peel color, electrolyte leakage (%), soluble solids (%), titratable acidity (g 100 g-1), soluble solids / titratable acidity ratio, pH and vitamin C (mg 100 g-1). Ozone reduced anthracnose severity in the short (3.3 ppm) and long term (1.5 ppm), making it as effective as a commercial fungicide. Ozone increased shelf life by seven days and maintained the postharvest quality of papaya fruits. Thus, ozone becomes a potential technology for postharvest use as a safe alternative to the use of pesticides in reducing anthracnose and increasing shelf life of papaya fruits.

“…Methods such as 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and 2,2′-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) have been used to determine antioxidant activity in many plant extracts 2, 3, 7. Previous studies7, 8, 9, 10, 11 showed that DPPH, ABTS, and FRAP can be used to determine the antioxidant potential of fruits, vegetables, beverages, and food.…”

Objectives In this study, we aimed to determine the antioxidant activities of two varieties of sesame ( Sesamum indicum L.) seeds using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), and ferric reducing antioxidant power (FRAP) method, and to investigate the correlation between total phenolic as well as flavonoid contents and antioxidant activities of the extracts. Methods The antioxidant activities were determined using DPPH, ABTS, and FRAP assays, and the total phenolic content (TPC) and total flavonoid content (TFC) were measured by ultraviolet (UV)-Vis spectrophotometry. The correlation between total phenolic and flavonoid contents and DPPH IC 50 , ABTS IC 50, and FRAP EC 50 values was analyzed by Pearson's method. Results The IC 50 DPPH values of all sesame seed extracts were in the range of 8.88–44.21 μg/mL and IC 50 ABTS values were in the range of 24.91–141.19 μg/mL. EC 50 FRAP value ranged from 222.40 to 872.57 μg/mL. The highest TPC of 1.57 g gallic acid equivalent (GAE)/100 g was observed in ethanolic extract of black sesame seed, while the highest TFC of 4.29 g quercetin equivalent (QE)/100 g was observed in ethyl acetate extract of white sesame seeds. The TPC in black sesame seed extract was significantly negative correlated with IC 50 ABTS value (r = −0.828, p < 0.01) and EC 50 FRAP value (r = −0.976, p < 0.01). Conclusions All sesame seed extracts were categorized as very strong antioxidants by DPPH assay. Phenolic compounds in black sesame seeds were found to be the major contributors to antioxidant activities by using ABTS and FRAP methods. White and black sesame seeds have the potential to be developed as sources of natural antioxidants.

“…A negative correlation was reported between yield, fruit size, and bioactive compound content [3,54,55]. Therefore, the content of these bioactive substances in tomatoes depends on the harvest, the agronomic interventions, and the genotype analyzed.…”

Soil cover is a major factor in the cultivation of creeping tomatoes, especially for in natura consumption. This study aimed to determine the combination of a suitable tomato hybrid and soil cover, resulting in superior production performance and quality attributes of tomato fruits. Tomato hybrids (Fascínio and Thaíse) were cultivated on five soil cover types (uncovered soil, plastic mulch, sorghum, Sudan grass, and pearl millet). The data were submitted to a principal component analysis (PCA), considering all the variables, through Biplot graphical analysis. A Pearson correlation analysis was performed at the 5% significance level. For biomass production, pearl millet and Sudan grass were distinguished from the other soil covers, showing lower decomposition rates and, consequently, longer half-lives. Covering with plastic mulch provided higher total (111 t ha−1) and commercial (74.4 t ha−1) yields, regardless of the analyzed hybrid. According to the PCA, soil cover management influences the production and quality of tomato fruits, except for chemical and post-harvest characteristics, and maintains ideal levels for commercialization for all treatments. The Fascínio hybrid presented better production attributes, higher total and commercial fruit production per plant as well as fruits with larger sizes, especially when grown in plastic mulch cover. The Fascínio hybrid also presented fruits with higher levels of bioactive compounds (lycopene and β-carotene).
