“…Table 2 summarizes the total content of glycoalkaloids and the main glycoalkaloids compounds identified and quantified in several potato peel varieties as well as the methods employed. As given in Table 2, among the most important are the triose glycosides of solanidine [39,40,[42][43][44][45], being normally the most abundant α-chaconine, followed by α-solanine [43,44,[46][47][48]. Other glycoalkaloids found in lower concentrations (see Table 2) were the solanidine (an alkaloidal aglycone), the demissidine (its dehydrogenated form), α-tomatine, and commersonine [41,45].…”

“…Glycoalkaloids are compounds characterized by their bitter taste and toxicity, comparable to arsenic [42,46]. Their ingestion in high concentrations (greater than 3-5 mg/kg of body weight) is associated with detrimental effects on human health, causing colicky pain in the abdomen and stomach, diarrhea, gastroenteritis, vomiting, confusion, hallucinations, rapid pulse, fever, and even neurological disorders [41,42,44,45,47,49]. Therefore, the concentration of glycoalkaloids in the potato's raw material must be less than 20 mg/100 g fresh weight [45,46].…”

“…Furthermore, because of the higher α-chaconine toxicity, it is usually considered as ratios of α-solanine/α-chaconine close to two [47]. However, SGA plays an important role in the defense of the plants against pests, pathogens, and insects [39,[41][42][43][44]. Hence, the rising interest in the study of glycoalkaloids as a source of permanent disease resistance, employing potatoes grown by introgression [39,40].…”

Identification and Recovery of Valuable Bioactive Compounds from Potato Peels: A Comprehensive Review

Nowadays, the potato is one of the most cultivated and consumed food crops in the world and, in recent years, its production has experienced a sharp increase. Its industrial processing generates several by-products that are wasted and cause economic and environmental problems. Among them, potato peel stands out, representing up to 10% of the total potato residues obtained in the processing. On the other hand, these wastes, in addition to presenting antioxidant compounds, are rich in interesting chemical compounds of great value in a biorefinery model. This review summarizes the main compounds present in potato skins as well as the most used and innovative extraction methods employed for their isolation, with special emphasis on the fractions with biological activities. In addition, a sustainable biorefinery proposal focused on obtaining high added-value products with potential applications in the pharmaceutical, food, nutraceutical, or cosmetic industries is included.

“…This technology was used to extract specifically α‐solanine and α‐chaconine from potato peel with their simultaneous conversion into β‐solanine and β‐chaconine, in a single‐stage process and without resorting to organic solvents. More interestingly, this technique showed the viability of concomitant extraction and chemical conversion of α‐solanine and α‐chaconine into β‐solanine and β‐chaconine using ultrasound (Alves‐Filho et al ., ). However, even though significant improvement in extraction efficiency is obtained using UAE, this technique still remains of high cost compared to chemical ones, and finding solutions to reduce these constraints, it is needed in order to industrialise effectively and widely this process.…”

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.

“…In terms of individual glycoalkaloids, the yields were 273, 542.7, 231 and 55.3 µg/g dried PP for alpha-solanine, alpha-chaconine, solanidine and demissidine, respectively, using UAE [47]. In addition, this technique proved the viability of the concomitant extraction and chemical conversion of alpha-solanine and alpha-chaconine into beta-solanine and beta-chaconine using US [48].…”

Potato peel (PP) is the major underutilised by-product in the potato-processing industry and a potential source of valuable bioactive molecules. Among them, glycoalkaloids and polyphenols are important precursors for steroid hormones and natural antioxidants, respectively. Moreover, the huge quantities of industrial potato-peel waste that are produced are a rich source of primary metabolites, which principally include starch as well as non-starch polysaccharides, proteins, lipids, lignin and cellulose. All carbohydrates are prone to undergo fermentation to produce ethanol, lactic and acetic acid. Finally, the main portion of PP is made up of alcohol-insoluble matter with a dietary fibre content of approximatively 40%. The present review summarises the recent advances and emerging technologies in potato-peel extraction and further valorisation processing in the food industry.
