Techno and bio functional characterization of industrial potato waste for formulation of phytonutrients rich snack product

Characterisation of industrial potato waste for suitability in food applications

“…PPP also possessed higher DPPH radical scavenging activity (83.12%) compared to PMP (10.26%) (Table 1), which could be due to the higher amount of phenolic components in potato peels. Phenolic compounds are considered to be the main contributor (58%–80%) to antioxidant potential in potato (Singh et al ., 2022). Azizi et al .…”

“…DPPH (1, 1‐diphenyl‐2‐picrylhydrazyl) radical scavenging activity of powders was estimated using the procedure described by Singh et al . (2022) and antioxidant activity was expressed as: Glycoalkaloids were analysed using the HPLC method as described by Azizi et al . (2020).…”

“…Techno‐functional properties such as water absorption capacity, oil absorption capacity, bulk density, solubility index, and swelling capacity were determined by using the methods explained by Singh et al . (2022).…”

Phytochemicals Derived from Agricultural Residues and Their Valuable Properties and Applications

“…Concerning cultivars, it was shown that the variety with blue flesh showed the highest concentration (5.68 mg/100 g fresh weight), followed by the red-leaved (5.26 mg/100 g fresh weight), while yellow or cream flesh. In the study of Singh et al [ 89 ] of potato peel, glycoalkaloids were detected as 1.05 mg/100 g. The results of Rytel et al [ 88 ] showed that the glycoalkaloid content of potato peel depends on the potato cultivar and ranges from 181 mg/kg to 3526 mg/kg of fresh potato tubers.…”

Environmental benefits of circular food systems: The case of upcycled protein recovered using genome edited potato

“…In Sweden alone, over 878 000 tons of potato were harvested in 2020, of which around 40% was used to produce potato starch (Wahlstedt, 2020). The remaining protein, fiber and trace nutrients arising as side streams are most commonly reused to produce dietary fiber (Sampaio et al, 2020;Singh et al, 2022;Dey et al, 2021), treated in biorefineries, anaerobic digestion, or evaporated and sold as animal feed or fertilizer (Souza Filho et al, 2017;Caldeira et al, 2020;Grommers et al, 2009). However, increased circularity and re-usability of by-products within the food system is identified as an important step towards sustainable food systems.…”
