Sprout Suppressive Molecules Effective on Potato (Solanum tuberosum) Tubers during Storage: a Review Michelle Boivin 1 & Nathalie Bourdeau 2,3 & Simon Barnabé 1,3 & Isabel Desgagné-Penix 1,3 Accepted: 20 July 2020 # The Potato Association of America 2020
Abstract Potatoes are at the heart of the world’s diet, being cultivated in more than 100 countries. Being the fourth largest crop after maize, wheat and rice, the potato production is of utmost interest for food industry, supporting a wide range of research projects. This is particularly the case of storage, an essential step for the potato industry, which is regularly studied. Indeed, sprouting of potatoes during storage is very problematic, resulting in a net loss for industries and increased food waste. Therefore, there has been a lot of research on sprout suppressive molecules since the beginning of the twentieth century. However, to date, there is no publication gathering all the studied molecules. This review presents an overview of the current knowledge on sprout suppressive molecules, natural and synthetic, along with a comparison of their effectiveness. Resumen Las papas están en el corazón de la dieta del mundo, cultivándose en más de 100 países. Siendo el cuarto mayor cultivo después del maíz, trigo y arroz, la producción de papa es de máximo interés para la industria alimentaria, respaldando una gran amplitud de proyectos de investigación. Esto es particularmente el caso de almacenamiento, un paso esencial en la industria de la papa que se estudia regularmente. De hecho, la brotación de las papas durante el almacenamiento es muy problemático, lo que resulta en pérdidas netas para la industria y en un aumento de desperdicio de comida. De aquí que ha habido mucha investigación en moléculas inhibidoras de la brotación desde principios del siglo 20. No obstante, a la fecha no hay una publicación que reúna a todas las moléculas estudiadas. Esta revisión presenta una vista general del conocimiento actual de moléculas supresoras de la brotación, naturales y sintéticas, junto con una comparación de su efectividad.

Introduction Although the history of potato began 8000 years ago in the Andean region of South America, it was only in the seventeenth century that this vegetable was adopted throughout Europe, and from there, imported to Asia before North America (International Year of the Potato 2008). Without being exhaustive, the average world’s production of potato * Isabel Desgagné-Penix [email protected] 1
