“…These products produce a large amount of potato peel waste (PPW) as by‐product (Stearns et al ., ; Gebrechristos & Chen, ). The PPW amount varies from 15% to 40% (Sepelev & Galoburda, ), depending on whether potato is peeled by abrasion, which is the most used technique because it is economically and technically interesting, by lye or by steaming (Feustel & Harrington, ; Schieber & Saldaña, ; Arapoglou et al ., ).…”

Potato tuber (Solanum tuberosum L.) is the fourth most important agricultural product after wheat, rice and maize. With a total production of 388 million in 2017, c.a. 70% of this total production is processed in developed countries, producing a large amount of potato peel waste (PPW) as by-product. Although PPW is considered as a zero-value by-product by the feed industry because it is too fibrous, for other recycling industries it is an inexpensive by-product due to its significant contents of some interesting nutrients particularly polyphenols and glycoalkaloids. In potato, and Solanum species in general, many glycoalkaloids, predominantly a-chaconine and a-solanine, have been chemically and structurally identified. However, further research is needed to expand the knowledge of the biological values of potato glycoalkaloids in order to develop a recycling process to extract these technologically and nutritionally interesting bioactive ingredients for different sectors, in particular, the agricultural, food and pharmaceutical ones, which are demanding natural, safe and eco-friendly ingredients.
