Modelling Potato Protein Content for Large-Scale Bulk Storage Facilities

Abstract

The potato (Solanum tuberosum) is one of the main sources of natural starch. In recent decades, the valorisation of potato protein that results as a by-product in the starch industry has been gaining interest as well. As potato supply is seasonal and the protein content of potatoes during long-term storage is temperature-dependent, optimal storage of potatoes is of great importance. This paper explores a model describing potato protein content during a full storage season for the Miss Malina and Agria cultivars. The model combines Michaelis-Menten protein kinetics with the Arrhenius equation. Laboratory analyses were performed to monitor the protein components in both potato cultivars and to use for estimation of the kinetic parameters. The results indicate that the two cultivars have different synthesis and degradation kinetics.

Acylation of agricultural protein biomass yields biodegradable superabsorbent plastics

“…Today, one of the largest underutilised agro-industrial protein side-stream is the potato protein concentrate (PPC), obtained after starch extraction 8 , 15 , 16 , 18 . The PPC is produced through acidification and harsh thermal processing of the downstream liquid (potato fruit juice, PFJ) from starch extraction, leading to intensive coagulation and recovery of the protein 19 – 21 . Global cultivation resulted in the production of more than 360 million tons of potato in 2018 22 , and ~3.7 million tons of potato starch were extracted, resulting in a production of ca.…”

“…The ether extract was determined by hydrolysis according to the Association of Official Analytical Chemists (AOAC) method 954.02 (2006). The crude protein was determined through the Coomassie Blue G250 staining method ( Grubben et al., 2019 ). Total soluble sugars were determined by the Anthrone colorimetric method ( Rudack et al., 2017 ).…”

Biostimulant potential of agro-industrial side-streams - sustainable sugar beet cultivation and drought tolerance in wheat

“…Some industrially produced gluten is used as a co-product for several purposes, e.g., within the baking industry [78]. However, the quantities of wheat gluten produced leave much scope for additional uses [72,[81][82][83]. To increase the applicability of wheat gluten, structural modification to enhance its functional properties is often required [71,72], as it is highly polymerized in its native state [14,74,77,81].…”

“…In 2018, the amount of PFJ obtained after starch extraction represented around ~1% (3.5 million tons) of the total global potato production (>360 million tons) [81,84,85]. In the past, PFJ was regarded as waste and was released into nearby streams and other water bodies, resulting in environmental pollution [82,83]. However, potato protein (PP) is a potentially valuable product that can be produced from PFJ through acidification and harsh thermal processing [14,86].…”
