The potato processing industry requires a wide range of processing equipment to produce a premium quality product. This topic deals with these techniques and technologies.

Novel Combined Freeze-Drying and Instant Controlled Pressure Drop Drying for Restructured Carrot-Potato Chips: Optimized by Response Surface Method
March 13 2018 by INKOA

Combined freeze-drying and instant controlled pressure drop process (FD-DIC) for restructured carrot-potato chips was developed and its processing conditions were optimized using response surface methodology (RSM) with the purpose of improving the quality of products and reducing energy consumption. Three critical variables including the amount of carrot, the moisture content of the partially dried product before DIC treatment, and equilibrium temperature of DIC for the restructured chips were considered.

Trends in global potato processing industry- Evidence from patents’ analysis
August 1 2017 by INKOA

Potato has been considered as a serious food security option worldwide and about 15.5% of potato tubers are processed into various products. This study undertakes analysis of patents data for having insight into the direction and extent of global research on potato processing. North America has demonstrated that protection of intellectual properties create global businesses, however massive efforts from China in recent years indicate their giganticfuture plans in potato processing. The study indicates that western developed world was skewed towards French fries and Potato Chips/ Crisps while China has greater balance in their focus as Other Potato products, Dehydrated Products and Processing Machineryhave also been adequately focussed.

Potential determinants of profits and market efficiency of potato market chains in Uganda
June 22 2017 by INKOA

The study aimed at understanding the level of inefficiencies in the potato market chain. Farmers sell potato to traders but continue to complain of limited market access and low profits. The purpose of this paper is to determine market efficiency and profits of the potato market chain, and factors that influence the profits. Design/methodology/approach: The study focussed on potato farmers, traders and small-scale processors. It was conducted in Kabale and Mbale districts being the major potato producing areas in Uganda, and Kampala being a major potato market. Data were collected from 180 farmers, 60 traders and 32 small-scale processors. Descriptive and regression methods were used to analyse the data. Findings: There were three major potato market chains and all were profitable and efficient. The farmer-buyer node was the most efficient (efficiencies of 128-159 per cent). The trader node efficiency ranged between 56 and 81 per cent. Sex of chain actor, group marketing, contract duration and distance to market were among the factors that affected profits. Research limitations/implications: Processors considered were those operating on very small scale, hence results do not apply to large-scale processing. Consumers were not included but the data and results are adequate for the study objective. Originality/value: This paper provides empirical information that serves as a basis to adopt market options for increased benefits to various chain actors.

Factors Enhancing Household Nutrition Outcomes in Potato Value Chain in South-Western Uganda
June 19 2017 by INKOA

In Uganda, agricultural commercialization has been promoted to reduce poverty and improve household food security. South-western Uganda, the major producer of potato, has been considered the food basket of the country but it has one of the highest prevalence rates of stunting in children under 5. This study considered potato enterprise as a key pathway for enhancing household food and nutrition security because it has become a major income source and staple in the diets of many households in the area and most urban areas in the country. The objective was to determine factors that influence farm household nutrition and food security outcomes. Through a survey, data were collected from 434 randomly selected potato farmer households. Descriptive and econometric methods were used in data analysis. Results show that household dietary diversity score was low (3.2) for most (57%) of the households. Only 38% were food secure. The main factors enhancing household nutrition outcomes were size of land, livestock units owned, proportion of household income spent on food, and education of household head, while farmer’s experience in potato production had a negative effect. The size of land owned, crop diversification, income from potato, age and education of household head, and a famer being male enhanced household food security outcomes. The study recommends promoting improved production practices to maximize land productivity, integration of livestock in potato production, and training women and men in household food and nutrition and related use of income.
