Low Storage Time of Cassava (Manihot esculenta) in Northern Peru: A qualitative approach

Abstract

Introduction: Manihot esculenta (Cassava, Mandioca or Yuca) is a starchy staple source of nutrients around the globe. In Peru the produce can be harvested in the Coast, Highlands and Jungle regions of the Country. Relative fast deterioration of the harbested root has been observed for many decades now. Materials and Methods: A qualitative approach was designed to investigate perishability of the produce after harbest through open interviews directed to Cassava sellers of the local market (Chota Province, Cajamarca Region, Peru, 2394 m.a.s.l.) which was continued until response saturation in consideration of in-situ thematic analysis. Microscopic observations were also performed, sampled tissue was fixed with KOH (10%). Results and Discussion: Years of Experience Selling Cassava, 4 - >15 and 25->30 years; the reported storage time once Cassava was aquired for sale at the market comprised four categories, 4 days, beetwen 8-10 days, around 15 days, and until 30 days; Cassava was aquired from Coast, Highlands and the Jungle regions, North-West Peru; sellers reported three varieties, “Machala”, “Blanca”, “Roja”; Flavorsome Cassava would perish faster whereas other varieties would last longer periods; perished staple was used as animal feed it ranged 20 – 30%. Literature related to observations refers as post-hasrbest physiological deterioration, moreover, microscopic observation did not allowed identification of any pervasive species and plate culture along with molecular techniques are suggested. Conclusion: Low Storage Time of Cassava roots as studied here indicated to be a decades-spannig isuue afecting the market in North Peru. Currently, there is data and techniques as to produce better varieties of Manihot esculenta. The authors present a novel approach to study crop production for North Peru.
