Assessment of pre- and post-harvest anti-sprouting treatments to replace CIPC for potato storage

Evaluating Ecologically Acceptable Sprout Suppressants for Enhancing Dormancy and Potato Storability: A Review

“…Sprouting is one of the most significant challenges in the postharvest storage of potato tubers and throughout the entire supply chain, as it reduces the quality and quantity of marketable produce, thereby resulting in financial losses [4][5][6][7]. Severe losses are incurred due to potato tuber sprouting and sprout growth since these cause alterations in tuber physical properties, such as reduced turgidity, induced shrinkage, and fosters weight loss [8,9]. Sprouting also leads to the accumulation of toxic compounds in the potato flesh, such as solanine and chaconine [9], and a reduction in nutritional and processing qualities [10].…”

Sprouting also leads to the accumulation of toxic compounds in the potato flesh, such as solanine and chaconine [9], and a reduction in nutritional and processing qualities [10]. Potato tubers are mainly consumed fresh, resulting in a yearly demand, and necessitating extended postharvest storage of tubers after harvest.…”

“…Several promising alternatives have been identified. For instance, S-carvone is a naturally occurring monoterpene that inhibits potato sprouting [9,[19][20][21]. Other promising compounds with significant potato sprout suppression properties include 1,4-dimethyl naphthalene [9,22,23], maleic hydrazine [24], and 3-decen-2-one [9].…”

Essential oils, and chemical components of essential oils such as monoterpenes, have also been tested and used as suppressants of sprouting in potato tubers with a significant level of efficacy [7,10,25].…”

“…Critical parameters that must be taken into consideration in the evaluation of chemical compounds for use as potato tuber sprout suppressants for the extension of dormancy and tuber storage management include the type of cultivar, chemical nature and bioactivities of the compound, dosage, storage temperature, and mode of application, among others [25][26][27]. Several studies have evaluated these parameters to determine how they influence the efficacies of sprout suppressants [4,9,24,26,28]. However, variations in these parameters among different studies reported in literature impede comparisons of the efficacies of different candidate sprout suppressants and the integration of these research findings to inform decisions on which of these novel sprout suppressants outperform the other.…”
