“…In low-temperature disorders, sparked temporary accumulation of calcium ion is significant by various calcium capturing proteins, thus facilitating numerous physiological reactions in the cell (6). Calcium treatment is demonstrated to be effective on different kinds of fruits and vegetables such as chili pepper (7), loquat (8,9), apple (10), peach (11,12), persimmon (13), papaya (14,15), gooseberry (16), strawberry (17), mango (18), purple shallot (19), soursop (20), tomato (21) and watermelon (22).

Banana is a delicious fruit with excellent nutrient components beneficial for human health. In postharvest, banana fruit is quickly ripe within few days at ambient temperature condition and its quality is seriously degraded afterwards. Extension of its stability during storage and distribution is very necessary to enhance its economic value. This research evaluated the effectiveness of CaCl2 treatment on the physicochemical quality attributes, phyto-chemical and antioxidant activities, and potential enzymes of banana fruit during storage. Banana fruits were dipped in 3% CaCl2 solution for 5 min before draining on racks for 30 min at ambient temperature to remove excess calcium chloride solution. Another banana group is dipped in clean water, leaved on racks for 30 min as the control. Both these fruit groups were then stored at 4±0.5oC with 85-90% relative humidity for 28 days. In 7 day-interval, each group is taken to verify quality attributes such as decay index, firmness, extractable juice recovery, ascorbic acid, carotenoid, total soluble solid, phenolic content, total flavonoid content, DPPH radical scavenging rate, H2O2 content, catalase (CAT) activity, superoxide dismutase (SOD) activity of banana fruit during storage. Our findings demonstrated that CaCl2 exerted a positive influence in limiting decay (2.24±0.11 mark); slowing down texture firmness reduction (7.25±0.10 N); enhancing the extractable juice recovery (85.49±1.12%); controlling ascorbic acid (12.79±0.13 mg/100 g), total soluble solid (16.40±0.13 oBrix), phenolic retention (161.35±1.19 mg GAE/100 g), flavonoid content (64.41±0.25 mg QE/100 g) and H2O2 accumulation (20.09±0.10 µmol/g); improving carotenoid (21.83±0.13 µg/100 g), catalase (15.28±0.12 U/g), superoxide dismutase activity (5.60±0.10 U/g), antioxidant capacity of banana fruit (46.20±0.15%) during chilling storage. CaCl2 treatment would be an effective approach to extend shelf life of banana fruit in commercial distribution.

“…Another chemical that may come into play is volatile hexanal excreted as an an alarm pheromone from the mandibular glands of O. longinoda. This compound is used by the fruit industri to increase shelf life of mangoes (Baltazari et al, 2020) and other fruits (Dhakshinamoorthy et al, 2020 and references therein), as it inhibits the development of B. cinerea, Co. gloeosporioides, Lasiodiplodia theobromae and Pe. expansum (Anusha et al, 2016;Song et al, 1996).…”

Crop diseases are a major problem posing serious threats to food security. Emergent plant diseases occur world-wide and have increased sevenfold from 1995 to 2010 (Barwell et al., 2021;Fisher et al., 2012). Their negative impact on crops has been estimated to equal the feed consumption of 8.5% of the world population (Fisher et al., 2012), and five of the seven most serious threats to food security are fungal plant diseases (Pennisi, 2010). Often pathogens build up resistance to synthetic fungicides, which shorten fungicide life span and increase the cost of this measure (Ma & Michailides, 2005). It is therefore imperative to develop current

“…These losses are higher in developing countries compared to the developed countries [ 4 ]. This is due to the lack or poor agricultural practices and specialized facilities such as cooling facilities, packaging materials, marketing systems, and infrastructure in developing countries [ 5 ] which delays produce reaching the markets on time and in good condition.…”

From the perspective of food categories, fresh produce are the leading sources of food loss and waste globally. Their highly perishable nature shortens their shelf-lives leading to high postharvest losses if not properly handled. Currently, these losses are estimated at sixty-six percent based on total weight. Reduction of these losses will ensure constant supply of food along the supply chain as well as economic empowerment of the rural poor. Hexanal which is a naturally occurring compound has been developed as an intervention to prolong shelf-life of delicate tropical fruits such as bananas while also maintaining their quality. However, empirical evidence is still required on the usefulness of hexanal to farmers. It is envisaged that such evidence would inform scaling up of the technology in Kenya. This study assessed willingness to pay for hexanal and the factors influencing WTP amounts among banana farmers in Meru County, Kenya. Primary data was collected from 130 respondents who were grouped into aware and not aware of Hexanal. Results indicate that farmers who are aware of hexanal had a higher mean WTP Ksh 466.47 (US $4.66) compared to those not aware Ksh 331.86 (US $3.32). Factors such as age and income influenced the WTP amounts between subsamples. The major key policy implication of the study is the importance of stakeholders investing in the dissemination of information on hexanal among farmers to enhance uptake.
