“…Aberrant temperature and/or immersion time can lead to weight loss, color change, reduction of resistance to pathogens, reduction of firmness, scalding (Brito et al, 2009), damage to appearance, rind burning, and reduced vitamin C levels similar to data from yellow passion fruit (Campos et al, 2005).…”

The efficiency of hydrothermal treatment for the control of several bacterial diseases has been reported in some studies, but there are a lack of results on post-harvest changes resulting from this treatment. The objective of this work was to evaluate the post-harvest quality of potatoes submitted treated via hot water immersion. Potato tubers of the cultivar Ágata were immersed in 40, 50, 60, or 70ºC water for 1, 6, 11 and 21 minutes and evaluated for firmness of pulp (F), soluble solids (SS), pH, titratable acidity (AT), total soluble sugars (AST), reducing sugars (RA), non-reducing sugars (ANR), and starches at 1, 5, 10, 15, and 20 days of storage. The experiment was conducted in a completely randomized design. The means corresponding to the factors in question were analyzed using the Dunnett test (5%). It was possible to conclude that all hydrothermal treatments used here altered the acidity of the tubers. The treatments at 40°C at all immersion times; 50°C for 1, 6 and 11 minutes; and 60°C for 1 and 6 minutes provided a longer post-harvest tuber life.

“…According to Brito et al (2009), the effects of hot water application on fruits or vegetables can cause weight loss, color change, reduction of resistance to pathogens, reduction of firmness and scalding. Treatment at 60ºC for 11 and 21 minutes or 70ºC for 6, 11, or 21 minutes should not be used because they degrade the product.…”

“…The mortality data (%) of all assays were adjusted based on the mortality of the control group (Abbott, 1925) and were analyzed separately. In first assay, the results are presented as percentage mortality and were converted using the Probit scale (Finney, 1971) as was performed by Brito et al (2009). In the first assay, the original mortality data were analyzed using the Kruskal-Wallis test (α=0.05) (Sas, 2003).…”

The aim of this study was to evaluate the insecticidal activity of the bioproducts proagrim, essential oil from fennel and orange oil, on the mortality of Ceratitis capitata Wiedemann (Diptera: Tephritidae). The study was divided into three parts: the first assay studied the insecticidal activity of the products on infested fruit; secondly, a bioassay was performed by ingestion of the bioproducts in an artificial diet, and the third assay assessed the activity of the products following topical application on insects. Insecticidal activity was evaluated by application of the products at concentrations of 0.0 (control),

“…Insects at larval stage were fed an artificial diet consisting of 400 g of carrot, 4 g of nipagin, and 80 g of brewer's yeast (BRITO et al, 2009); and with a 10% honey solution during the adult stage. The oils used in the study were obtained from local stores.…”

Repellent activity of essential oils against mediterranean fly and their effects on postharvest quality in paluma guava

et al. 2023

View full text Add to dashboard Cite

Brazil is one of the world's largest guava (Psidium guajava) producing countries, but the economic performance of this crop can be negatively affected by the damage caused by Ceratitis capitata (Diptera: Tephritidae). The main methods for controlling C. capitata are based on broad-spectrum insecticide applications. However, the negative effects of using this control method stimulate the development of sustainable alternatives, such as the use of essential oils (EO). In this sense, the objective of the present study was to evaluate the repellent activity of EO of citronella (Cymbopogon nardus), clove (Syzygium aromaticum), and copaiba (Copaifera officinalis) for repellency of C. capitata in Paluma guava fruits and determine their effects on postharvest fruit quality, under laboratory-controlled conditions. The fruits were treated with citronella, clove, and copaiba EO and placed in covered plastic containers attached to the ends of arenas of 20 cm diameter and 15 cm height. The fruit physical and chemical analysis was carried out based on the same oils applied in the repellent test. The C. nardus essential oil presented a greater repellency of C. capitata females. The EO applications proved to be a good strategy for maintaining the fruit post-harvest quality.
