innovative small scale Postharvest technologies for reducing losses in horticultural crops
Ethiopian Journal of Applied Science and Technology, 2013Co-Authors: Lisa KitinojaAbstract:A comprehensive research project reassessed 12 past international horticultural projects, characterized current causes of Postharvest losses of 18 horticultural crops in four countries, then field tested a variety of low cost Postharvest Technology innovations that could potentially reduce these Postharvest losses, improve market value and improve incomes for small farmers. This presentation briefly outlines the Postharvest technologies found to be most successful, the technologies were not adopted or not maintained after the end of past projects, the most common knowledge gaps found for 30 commodity systems. The results of a series of field trials and cost/benefit analyses of potential Postharvest Technology innovations led to identification of many small-scale innovations that can reduce Postharvest losses, add value and improve returns by at least 30%. The concluding consensus recommendation is to avoid building expensive, complex Postharvest infrastructure that is difficult for smallholders to utilize and manage, and instead to promote integrated Postharvest management systems focusing on incremental adoption of small scale Postharvest innovations.

Appropriate Postharvest technologies for small scale horticultural farmers and marketers in Sub-Saharan Africa and South Asia - Part 2. Field trial results and identification of research needs for selected crops
Acta Horticulturae, 2012Co-Authors: Sunil Saran, Susanta K. Roy, Lisa KitinojaAbstract:Part 2 of 2. Based upon findings on the causes of Postharvest losses and quality problems for key horticultural crops in Sub-Saharan Africa (SSA) and South Asia, 32 potential Postharvest technical solutions were identified and investigated further. An additional 28 options related to production, extension and marketing activities were identified but not tested during this project. The objective was to identify Postharvest Technology interventions that would specifically address the identified priority problems and serve to reduce food and value losses, and that are of appropriate scale, cost effective, easy to use on a trial basis and capable of generating increased incomes by at least 30% for small farmers. Field trials were conducted on 19 of these intervention options, and cost/benefit analyses were conducted on 21 cases of improved handling, packing, storage and processing practices in India, Nepal, Ghana, Rwanda, Cape Verde and Benin. In 81% (17) of cases, the Postharvest technologies were determined to be cost effective and of appropriate scale for successful adoption and management by small scale horticultural producers and marketers in Africa and South Asia. Field assessments and preliminary field trials led to the identification of additional research needs for selected crops, and recommendations are provided for future studies in small scale Postharvest Technology.

Postharvest Technology for developing countries: Challenges and opportunities in research, outreach and advocacy
Journal of the Science of Food and Agriculture, 2011Co-Authors: Lisa Kitinoja, Sunil Saran, Susanta K. Roy, Ahmad Abdul KaderAbstract:This article discusses the needs and challenges of developing good, science-based, simple methods for Postharvest handling that can be made available in developing countries. Some of the traditional challenges have been successfully met (i.e. identifying causes and sources of losses for key crops, identifying many potential Postharvest technologies of practical use for reducing losses), but many challenges remain. These include the characterization of indigenous crops in terms of their unique Postharvest physiology (e.g. respiration rate, susceptibility to water loss, chilling sensitivity, ethylene sensitivity), ascertaining the differences between handling recommendations made for well-known varieties and the needs of local varieties of crops, and determining cost effectiveness of scale-appropriate Postharvest technologies in each locale and for each crop. Key issues include building capacity at the local level in Postharvest science, university teaching and extension, and continued adaptive research efforts to match emerging Postharvest technologies to local needs as these continue to change over time. Development of appropriate Postharvest Technology relies upon many disciplines that are relevant to the overall success of horticulture, i.e. plant biology, engineering, agricultural economics, food processing, nutrition, food safety, and environmental conservation. The expanding pool of new information derived from Postharvest research and outreach efforts in these areas can lead in many directions which are likely to have an impact on relieving poverty in developing countries.

Capital $ Investment in Postharvest Technology & Recovery of Invested Capital
1999Co-Authors: James R. Gorny, Lisa KitinojaAbstract:In today’s competitive global agricultural market it takes more than knowing how to effectively produce crops to succeed in business. Marketing fruits and vegetables at acceptable profit margins may involve timing the market either early or late in the season, to receive higher prices. Many producers undertake the strategy of trying to be the first grower/shipper to market product when prices are high and customer demand is strong. To execute this strategy special cultivars of fruits and vegetables have been developed by plant breeders and seed companies to mature very early in the season and allow grower/shippers to capitalize using this marketing stategy. Marketing produce late in the season or during the off-season is achieved by utilizing appropriate Postharvest handling technologies. These technologies if used properly not only extend the marketable shelf life of fresh fruits and vegetables but allow grower/shippers marketing opportunities such as:

sweet cherry composition Postharvest preservation processing and trends for its future use
Trends in Food Science and Technology, 2016Co-Authors: Suwimol Chockchaisawasdee, John B. Golding, Quan V Vuong, Konstantinos Papoutsis, Costas E StathopoulosAbstract:Abstract Background Sweet cherries (Prunus avium L.) are a nutritious fruit which are rich in polyphenols and have high antioxidant potential. Most sweet cherries are consumed fresh and a small proportion of the total sweet cherries production is value added to make processed food products. Sweet cherries are highly perishable fruit with a short harvest season, therefore extensive preservation and processing methods have been developed for the extension of their shelf-life and distribution of their products. Scope and approach In this review, the main physicochemical properties of sweet cherries, as well as bioactive components and their determination methods are described. The study emphasises the recent progress of Postharvest Technology, such as controlled/modified atmosphere storage, edible coatings, irradiation, and biological control agents, to maintain sweet cherries for the fresh market. Valorisations of second-grade sweet cherries, as well as trends for the diversification of cherry products for future studies are also discussed. Key findings and conclusions Sweet cherry fruit have a short harvest period and marketing window. The major loss in quality after harvest include moisture loss, softening, decay and stem browning. Without compromising their eating quality, the extension in fruit quality and shelf-life for sweet cherries is feasible by means of combination of good handling practice and applications of appropriate Postharvest Technology. With the drive of health-food sector, the potential of using second class cherries including cherry stems as a source of bioactive compound extraction is high, as cherry fruit is well-known for being rich in health-promoting components.
