“…Physiologically, an increase in respiration rate leads to a quick utilization of substrates, such as free sugars that contributes to post-harvest losses as previously reported by [16]. Similar findings of extended shelf-life have been reported in other banana varieties such as 'Grand naine' [6,7] and in other fruits including mangoes [17], papaya [18], Lime [19] and tomatoes [20]. The observed reduced rate of ethylene evolution in the treated fruits may be as a result of hexanal being a weak inhibitor of ethylene as previously reported by Tiwari and Paliyath,[21].…”

The short shelf-life of fruits in the tropics continues to be a pressing problem for farmers and other value chain actors. Hexanal is a naturally occurring compound that has received attention as a novel postharvest compound preservative. This study was conducted to determine the effect of hexanal on enhancing the postharvest shelf-life and quality of ‘sweet banana’ fruits. Two hexanal concentrations (2% and 3%) were applied as either a pre-harvest spray or a post-harvest dip. Fruits were obtained from two different agro ecological zones of Kenya (AEZs II and IV). The treated fruits were kept under ambient room conditions of 25 ± 1°C and RH 60 ± 5% to ripen. Hexanal treatment maintained the fruits quality and prolonged the shelf-life by 6 days in the dipped fruits, 6 and 3 days in the sprayed fruits from the drier AEZ IV and colder AEZ II respectively compared to the untreated controls. Hexanal treatments significantly (P = .05) delayed or reduced the rate of most of the physicochemical parameters analysed irrespective of the concentration and mode of application used. Fruit firmness was significantly (P = .05) maintained up to day 6 and 9 of storage in the treated fruits compared to the controls which softened drastically as from day 3 and 6 in the sprayed and dipped fruits respectively. Hexanal treatment delayed ethylene and respiratory peaks by 3 days in both modes of application and significantly delayed progression of other ripening related changes such as 0Brix, titratable acidity, simple sugars and vitamin C. Sensory evaluation showed no significant differences in the various quality attributes analysed between the hexanal treated and control fruits. The results of this study indicate that, use of hexanal is a potential technology that could be adopted by banana farmers to enhance post-harvest shelf-life without compromising on quality.

“…The ability of hexanal-based formulations to inhibit PLD activity, reduce membrane degradation, and enhance postharvest shelf life has been demonstrated for both climacteric and non-climacteric fruit (Paliyath et al 2003;Paliyath and Subramanian 2008). Hexanal-based formulations have been used successfully as preharvest sprays to increase postharvest quality of sweet cherry (Sharma et al 2010), strawberry (El Kayal et al 2017b), nectarine (Kumar et al 2018), tomato (Cheema et al 2014), guava (Gill et al 2016), and mango (Anusuya et al 2016). These studies were in a wide range of geographic locations, examined a variety of fruit species, and demonstrate the potential of hexanal to enhance postharvest quality and shelf life for many economically important fruit species.…”

“…There has been increasing interest into extending the longevity of horticultural produce through the inhibition of PLD, an enzyme involved in fruit deterioration (Paliyath and Subramanian 2008;Sharma et al 2010;Cheema et al 2014;Gill et al 2016;El Kayal et al 2017a, 2017bKumar et al 2018). Phospholipase D activity is strongly inhibited by hexanal, a naturally occurring, volatile C 6 aldehyde (Paliyath et al 1999;Paliyath et al 2003; Tiwari and Paliyath 2011).…”

“…Hexanal is the active ingredient of the "Enhanced Freshness Formulation" (EFF; Paliyath et al 2003;Paliyath and Murr 2007) that is used to inhibit the catabolic reactions that are controlled by PLD. Preharvest spray application of EFF can extend the shelf life of several commercially important fruit crops such as nectarine (Kumar et al 2018), tomato (Cheema et al 2014), guava (Gill et al 2016), sweet cherry (Sharma et al 2010), and strawberry (El Kayal et al 2017b) through the inhibition of PLD. In addition to enhancing shelf life, preharvest sprays of EFF were shown to increase fruit retention of mango (Anusuya et al 2016) and raspberry (El Kayal et al 2017a).…”

Growers are challenged to provide premium, ripe haskap fruit to market while limiting the negative attributes associated with over-ripening. Hexanal is an inhibitor of phospholipase D, an enzyme involved in membrane degradation, and has shown promise in extending the longevity of fruit. This study investigated the performance of a hexanal-based preharvest spray for enhancing the quality and shelf life of haskap fruit, an emerging crop in Canada. At two locations in 2015, 2016, and 2017, five cultivars were sprayed with a control treatment or a 0.02% hexanal formulation at 2-3 wk before harvest. Fruit was stored at 4°C and assessed for quality at successive times. Although inconsistent, results suggest a hexanal spray may impart a small benefit to the postharvest quality of haskap fruit. Secondary objectives included describing important agronomic characteristics of haskap and assessing the potential of a hexanal preharvest spray for enhancing fruit retention. Hexanal did not reduce fruit drop and had no effect on quality at harvest. Fruit contained high levels of soluble solids and titratable acids, were very dark in colour, and did not degrade in quality as rapidly as softer fruit crops such as strawberry or raspberry.

“…Several techniques have been reported to reduce fruit drop and increase retention of fruit on orange trees [11][12][13][14][15][16]. For example, an aldehyde (n-hexanal and (E)-2-hexanal) improves fruit retention on trees and fruit quality such as aroma, skin colour, and firmness [17,18]. Similarly, auxin alleviates fruit abscission at post-bloom and early development stages of the fruit, which results in the reduction of fruit drop [11].…”

Background Orange (Citrus sinensis L.) production in Tanzania is constrained by several pre-harvest factors that include pests. Hexanal, sprayed as Enhanced Freshness Formulation (EFF) is a relatively new technology that has been reported to reduce pre-harvest loss in fruits. However, the effects of hexanal on pre-harvest yield loss of orange are not known. We studied the effects of hexanal as EFF on yield losses of three sweet orange cultivars namely, Early Valencia, Jaffa, and Late Valencia. Factorial experiments tested the effects of EFF concentration, variety, and time of EFF application on number of dropped fruit, percentage of non-marketable fruit and incidence of pest damage. Results Results showed significant negative correlation (p < 0.001) between EFF and the percentage of dropped fruit, non-marketable yield, and incidence of pest damage. An increase in hexanal concentration by 1%, is expected to reduce number of dropped fruit by 50, percentage of non-marketable by 35.6, and incidences of pest damage by 36.5% keeping other factors constant. Results also show significant association (p < 0.001) between time of hexanal application and non-marketable yield. Percentage of dropped fruit is expected to increase by 1 for each day away from harvest, keeping other factors constant. Conclusion Pre-harvest application of hexanal as EFF can significantly reduce number of dropped fruits, percentage of non-marketable fruit and incidence of pest damage.
