Handling Practices

A significant portion of harvested produce never reaches the consumer due to, postharvest diseases. Various chemicals have been used to reduce the incidence of postharvest diseases. Many of these materials have been removed from the market in recent years due to economic, environmental, or health concerns. Although somewhat limited in the range of diseases controlled, chlorination is effective when combined with proper postharvest handling practices. Additionally, it is a relatively inexpensive postharvest disease control method that poses little threat to health or the environment. The proper use of chlorination in the management of postharvest diseases in fresh fruits and vegetables is discussed.

Postharvest handling of the potato is an important factor not only in preventing postharvest losses but also in maintaining its safety and nutritional quality. Exposure of the potato to unfavorable conditions such as light, extreme temperatures, and bruising can result in accumulation of glycoalkaloids, which are toxic substances. This study was a cross-sectional survey which aimed to investigate the postharvest handling practices of potatoes and perception of potato safety among open air market traders in Nairobi County, Kenya. Information was collected from 100 potato traders using a semistructured questionnaire that assessed postharvest handling practices such as potato transportation, exposure to sunlight, and storage. Results indicated that most of the potatoes (88%) took one day to be transported to the market, with the storage period at the market ranging from 2 to 3 days for most traders (42%). Forty-seven percent (47%) of the vehicles and hand-pulled carts used to transport potatoes had open backs, while 53% had closed backs. Over half (69%) of the potatoes in the markets were directly exposed to sunlight, with 75% of the traders leaving their potatoes in the open covered with a polythene bag after the day’s activities. Greening, sprouting, or bruised potatoes were mostly sold as seed, sold to restaurants and French fries vendors, or sold to consumers at a lower price. More than half of the traders did not think that consumption of greened potatoes is harmful to health. The results clearly show that there is poor handling of the potatoes by the traders which increases the risk of consumer exposure to glycoalkaloids. There is, therefore, a need to create awareness among traders on appropriate postharvest handling of potatoes to protect consumer health and reduce economic losses as well.

Background. Fresh vegetables such as tomato should have low microbial population for safe consumption and long storage life. The aerobic bacterial count (ABC) and coliform bacterial count (CBC), yeast, and mold population are the most widely used microbial indicators in fresh vegetables which should be lower than 4 log CFU g−1for safe consumption. The stages of the supply chain, postharvest handling methods, and crop varieties had significant effects on microbial population. ABC, CBC, yeast, and mold population were significantly highest (P<0.05) at retail market (5.59, 4.38, 2.60, and 3.14 log CFU g−1, resp.), followed by wholesale market (4.72, 4.71, 2.43, and 2.44 log CFU g−1, resp.), and were least at farm gate (3.89, 3.63, 2.38, and 2.03 log CFU g−1, resp.). Improved postharvest practices (washing in clean water and grading and packaging in clean plastic crate) helped to reduce ABC, CBC, and mold population by 2.51, 32.70, and 29.86 percentage as compared to the conventional method (no washing and no grading and packaging in mud plastered bamboo baskets). Among varieties, Pusa ruby had the lowest microbial load of 2.58, 4.53, 0.96, and 1.77 log CFU g−1for ABC, CBC, yeast, and mold count, respectively. Significantly negative correlation (P<0.05) was observed between fruit pH & ABC and pH & mold count. Although the microbial quality of fresh tomato is safe in the local market of western Terai of Nepal both in conventional and in improved practices however still it is essential to follow improved postharvest handling practices in production and marketing of newly introduced tomato cultivars (high-pH cultivars) for ensuring the safe availability of fresh tomato in the market.

Cayenne pepper (Capsicum frutescens L.) is a species of chili that is usually consumed daily and used by the food industry. Although cayenne pepper has important roles, it is often found rotting before it is reached by consumers. Postharvest handling that did not apply good handling practices can cause decomposition of cayenne peppers. This decayed can be caused by the activity of microorganisms, such as bacteria. This study aims to isolate and examine the biochemical properties of spoilage bacteria in cayenne pepper. The stages of the experiment involved: isolation and purification of the bacteria, observation of cell morphology and colonies, and biochemical examination. The results showed that bacterial isolates in cayenne pepper had rod-shaped cell characteristics, shiny colony surfaces, and jagged colony edges. Biochemical characteristics show that these bacteria have enzyme catalase activity, phosphatase enzyme activity, are able to produce carotenoid and lecithinase. However, these bacteria can not hydrolyze starch and pectin. These biochemistry characteristics were not identic with Xanthomonas campestris. Based on the assessment of lactose fermentation, indole, methyl red, and Voges-proskauer, these bacteria could not be identified as Erwinia carotovora.

In Sub-Saharan Africa, video has been earmarked as an important tool to enhance learning among smallholder farmers. The study evaluated how the inherent video attributes influence learning about postharvest handling practices and technologies from the perspective of maize farmers in Kakumiro district of Uganda; using the case of Access Agriculture maize videos. An action-oriented research involving showing of four videos, on-site participant observation, six key informant and 50 exit individual interviews were conducted in February 2019. While thematic-content analysis was applied for qualitative data, quantitative data were analyzed using SPSS 18.0 version. Our results clearly illustrate that the video’s ability to influence farmer learning depends on the complementarity of its positive attributes including: demonstration ability, attractiveness and clarity of images, ability to arouse interest and curiosity; thus, fostering interactions among viewers. The nature of video content in terms of clarity, practicability, relevance, applicability and content sequencing are also perceived to be key attributes of video in enhancing learning among the viewers. However, the effectiveness of video is likely to be compromised by the socio-economic and cultural factors more especially if such factors are not well taken care of during the filming process. If possible, when developing videos for farmer learning, focus should be on creating local content that is context specific, which farmers can enjoy and relate to for easy adaptation and eventual application.
