Post-harvest technology change in cassava processing: a choice paradigm

Open Access Article; Available online: 27 Jan 2020This study employed a choice model to examine the factors influencing the choice of post-harvest technologies in cassava starch processing, using a sample of five hundred and seventy (570) processors in the forest and guinea savanna zones of Nigeria. In addition, the profitability of various post-harvest technologies in the study area was assessed using the budgetary technique while the impact of improved post-harvest technology on processors’ revenue and output was analysed using the average treatment effect model. Sex of the processor, processing experience, income, and cost of post-harvest technology, the capacity of post-harvest technology and access to credit amongst others significantly influence the choice of post-harvest technologies. Although the use of improved post-harvest technology comes with a high cost, the net income from its use was higher than the other types of post-harvest technologies, suggesting that the use of improved techniques was more beneficial and profitable. In addition, using improved post-harvest technology had a positive and significant effect on output and income. These findings shows that investment in improved post-harvest technologies by cassava starch processors and other stakeholders would increase income, thus, improving welfare

Post-harvest technology

In recent years great interest is envinced in several countries in the culture of molluscan shellfish. In the tropics favourable conditions exist for rapid growth and marketable oysters are obtained with in vir^n to twelve months. Investigations have been conducted at the Central Marine Fisheries Research institute and success has been achieved in perfecting the techniques of oyster culture in coastal waters (Nayar and Mahadevan, 1983). The awareness that shellfish have to be purified and rendered harmless goes back to the time of the Roman Empire. During the first century B.C. the Romans consumed cockles and oysters after treating them in tanks known as cockle washery (Yonge, 1962)

The incidence of post-harvest problems among small farmers surveyed in three regions of the Limpopo Province

High yielding varieties and new production technology have vastly increased the world's agricultural production and provided rural incomes and affordable food for large parts of the population. While production research has received considerable attention, until recently, post harvest activities have not received much attention. Post harvest research has significant contribution towards the alleviation of poverty, food insecurity and the sustainable use of resources. The objective of the paper is to assess the post-harvest constraints affecting main staple grain crops in three regions of the Limpopo Province. Some of the most common post harvest constraints revealed by the study are, weevils, rodents and transport for produce from the field to home Chemical, biological and indigenous control measures are used by the smallholder farmers to alleviate some of the post harvest constraints. The results of the study seem to indicate that more research work should be done especially on the use of indigenous knowledge towards the alleviation of post harvest constraints.Crop Production/Industries,

The traditional post-harvest handling of robusta coffee doesn’t provide good quality results, which then motivates the government to take steps by providing technological assistance in stages. The research was aimed to determine the adoption process of robusta coffee post-harvest technology and analyze the correlation between attitudes, risk-taking courage, and skills on the adoption of coffee farmers' technology in Temanggung Regency. The location of this research was determined purposively. The number of respondents was 94 samples using Slovin method and taken from three villages, consist of Giyono, Jamusan, and Jombor. The post-harvest technology used by farmers in Jumo District were wet processing, dry processing, roasting, and coffee bean packaging technology. The results showed that farmers in Jumo District have gone through five stages of adoption in adopting the post-harvest technology assistance provided, namely awareness, interest, evaluation, trial, and adoption. Significantly, there is a very close relationship between attitudes, courage to take risks and skills towards technology adoption with correlation coefficient values were 0.896, 0.929, and 0.900, respectively. There needs to be more intensive assistance to improve farmer skills in using post-harvest robusta coffee technology, especially for farmers in the older age group and farmers with low education.Keywords: behavior, post-harvest, robusta coffee, technology adoption

Post harvest technology

In India, the seaweeds are harvested by handpicking. In the United States rapid industrialisation has been brought 'in during 1917-1918 in harvesting the Macrocyst/s beds by mechanical harvestors (Dawson, 1966). Mathieson (1969) described the harvest of Macrocyst/s using motor-driven barges with mowers. The mechanical harvestors cut the kelp canopy just under one metre below the water surface and transport the material to the barge. This way, several hundred tons of seaweed can be cut in a day. After being harvested, the material is washed and chopped, and the algin extracted

A review on the integrated agro-technology of papaya fruit

The aim of this review was first to explore the effect of different pre-harvest factors affecting the quality of papaya including genetic factors, climatic conditions, cultural practices on post-harvest quality of the papaya fruit. Post-harvest physiology of papaya in terms of its respiration, ethylene production and sensitivity and transpiration was reviewed. Post-harvest handling and factors affecting quality of papaya were also examined. Post-harvest biochemistry of papaya including enzyme activity, carbohydrates, organic acids, pigments and volatiles in papaya fruit were assessed. A review on post-harvest handling of papaya fruit including packaging and storage environments (temperature and relative humidity) were presented. On the other hand, the post-harvest microbiology of papaya was reviewed. Papaya supply chain is much limited to local destinations with quite few exceptions mainly due to lack of integrated post-harvest handling technologies. Pre- and post-harvest treatments were found to have a significant effect on post-harvest quality of papaya and the fruit storage stability under dry and hot climatic conditions of Africa. An integrated agro-technology research and development approach aimed at improved yield and quality at harvest as well as the maintenance of qualities of papaya fruit in order to encourage farmers to produce and for marketing of the papaya fruit under African local supply chain conditions and for export market is recommended.Key words: Papaya fruit, post-harvest, agro-technology, pre-harvest

Post Harvest Technology and Value Addition in Fruits

Not AvailableCentral Research Institute for Dryland Agriculture, Hyderabad - 500 059 Dryland Horticulture and Agri-Horticultural systems as an alternate land use system have gained much importance in recent years, as the fruit crops are highly remunerative for replacing subsistence farming and thus alleviate poverty level in rainfed, dryland, hilly and arid ecosystems. These crops have potential for development of wastelands through planned strategies, need comparatively less water than food crops, provide higher employment opportunity and environment-friendly. Fruits are undoubtedly very important for nutrition security with high potential of value addition and foreign exchange earnings. Tropical fruits are now considered as an important item of commerce as they have gained enormous market potential. Post-harvest losses of fruits and vegetables are more serious in developing countries than those in well-developed countries. The total losses from harvest to the consumer point are as high as 30-40%, which is worth thousands of crores of rupees. About 10-15% of fresh fruits and vegetables shrivel and stale, lowering their ;market value and consumer acceptability. Minimizing these losses can increase their supply. It will also keep pollution under control. Improper handling and storage cause physical damages due to tissue breakdown. Mechanical losses include bruising, cracking cuts, microbial spoilage by fungi and bacteria, whereas physiological losses include transpiration, pigments, organic acids and flavour. About 30% of fruit decay due to Pnricillium species. Tropical fruits, which are at present under-utilized have an important role to play in satisfying the demand for nutritious, delicately flavoured and attractive natural foods of high therapeutic value. They are in general are accepted as being rich in vitamins, minerals and dietary fibre and therefore are an essential ingredient of a healthy diet (Table). Apart from nutritive, therapeutic and medicinal values quite a few of these tropical fruits have excellent flavour and very attractive colour. Fruits like jamun and phalsa are highly perishable. Bael fruit is not an easy to eat out of hand item. Many people because of its strong astringent taste do not like fresh Aonla fruit. However, these fruits have unlimited potential in the processed form and consumers all over world can get opportunity to enjoy the fruits in the form of their processed products.Not Availabl
