Once leafy vegetables are picked, metabolism and inoculating microbes affect the quality of the products badly. This paper included a brief introduction on the various factors affecting the freshness and shelf-life of leafy vegetables, with 3 types of treatments: antimicrobial gas or washing solutions (ozone, hydrogen peroxide, peroxyacetic acid, chlorine, electrolyzed oxidizing water, and silver solution), that are broadly applied on post-harvest leafy vegetables that help to reduce both spoilage microorganisms and pathogens.

Peach is a climacteric highly-perishable fruit whose post-harvest preservation relies largely on cold storage. The combination of the last with other technologies allows to extend the shelf life of this product. One alternative is the utilization of salicylic acid, a natural compound involved in many physiological phenomena such as resistance against diseases and ripening. Considering these facts, the objective of the present work was to evaluate the effect of pre-harvest application of salicylic acid solutions on the quality of ‘Chimarrita’ peaches during post-harvest cold storage. The experiment was conducted at the Federal University of Pelotas/RS, in the campus of Capão do Leão/RS - Brazil. The application of salicylic acid solutions was performed by direct pulverization on the fruits, 30 days prior to harvest. The concentrations were: 0,0 (control); 1,0; 1,5; and 2,0 mM. After harvest, the fruits were stored in a cold chamber at 1,0 ± 0,5°C and 85-90% RH, for 30 days. The analyses were performed at the following cold storage periods (plus 2 days at room temperature of 20°C to all treatments, in order to simulate commercialization conditions): 10 (+2) days; 20 (+2) days; e 30 (+2) days. The variables evaluated were: mass loss (%); flesh firmness (N); DA index; color (L, a*, b* and hue angle); wooliness incidence (%); rot incidence (%); total soluble solids (°Brix); pH; titrable acidity (% of organic acids); and ratio. The salicylic acid doses and/or the cold storage periods had significant effects on all the evaluated parameters. For most of the parameters analyzed, the intermediate dosis of 1mM (and also 1,5mM) of salicilic acid showed the most promising results. Therefore, the application of salicylic acid solutions 30 days prior to harvest is a technique which can be combined to cold storage in order to shift the quality and the shelf-life of ‘Chimarrita’ peaches.

Shelf life of horticultural commodities is dependent on postharvest handling but also on a wide range of pre-harvest factors, which include genetic and environmental parameters. This study was conducted to explore the influence of cultivar, leaf position, and piece position on the leaf on visual quality of fresh-cut butterhead lettuce as well as the effect of a wide range of cultivation seasons on the postharvest quality and shelf life of baby leaves (spinach and ‘wild’ rocket). Six butterhead lettuce cultivars were used (cultivated soilless in an unheated plastic greenhouse) while the effect of leaf position on the plant (outer and inner leaves) and the piece position on the leaf (piece one close to the leaf base and piece four close to the top) were also evaluated. Baby leaves were cultivated under an unheated plastic greenhouse for winter production and under a nethouse for the rest of the growing season, with a total of five and seven sampling dates for spinach and ‘wild’ rocket respectively. The cultivar of butterhead lettuce had a significant effect on postharvest quality of fresh-cut product but more important was the piece position on the leaf. When this was closer to the base of the leaf, there was more browning on cut edges and limited shelf life for the fresh-cut lettuce. The result was associated in one tested cultivar with PAL activity, which was higher by 106% for piece one compared to piece four as an average for the whole storage period. The growing season of baby leaves had a great impact on their shelf life, with the season of mild environmental conditions achieving the highest marketability.

One of the main problems faced by mango growers in the San Francisco Valley, Brazil, is caused by fungi. Among them, the genus Alternaria, Lasodiploida and Colletotrichum stand out. Sanitization methods have been studied in order to control the proliferation of these microorganisms and increase the shelf life of the fruits. Thus, two methods of sanitization were evaluated: Ozone and chlorine dioxide, in the control of fungi of the genus Alternaria and in the increase of post-harvest quality of Palmer mango fruits. We used a 3 × 5 factorial design with three treatments applied to fruits previously inoculated with fungi, five evaluation periods and five replications, totaling 75 experimental units. The treatments consisted of ozonated water at 3 ppm, chlorine dioxide at 12 ppm, and a control without sanitization. We noted the full development of fungi from the 10th day after contamination, more significantly for the control and to a lesser extent for the treatment with ozone. The methods of conservation with ozone and chlorine dioxide proved efficient in the conservation of fruits. The treatment with chlorine dioxide shows a significant efficiency in the control of penetration of fungi of the genus Alternaria inside the fruits.
