![]() For instance, the cultivar Russet Burbank shows protein contents that fluctuate within two different studies, while for the cultivar Pentland Dell, similar contents were found in two different studies. Notice from Table 1 that a wide range of protein contents is found. 2002), while others reported a decrease (Nowak 1977 Kumar and Knowles 1993). 1996, 1997) or a constant protein content (Mazza 1983 Blenkinsop et al. As Table 1 shows, some long-term storage studies found an increase in protein content (Brierley et al. The dynamics and fluctuations of the protein content vary, especially between different potato cultivars. The economic optimum of potato protein production depends on the proteins formed during growth, the capacity of the processing industry, and any protein losses or synthesis during storage.ĭuring long-term storage, both protein degradation and protein synthesis take place continuously and, as previously found, total soluble protein levels fluctuate (Nowak 1977 Brasil et al. As potatoes are a seasonal crop, storage of potatoes is essential to be able to provide potatoes all year round. The quality and amount of proteins in potatoes are determined by the conditions during the growing season. ![]() Protein quality is therefore becoming increasingly important in the industrial production of potato proteins (Grommers and van der Krogt 2009). In addition to the present food application and feed supplements, potato proteins are of great potential in specific biotechnological and pharmaceutical applications (Kong et al. Therefore, potato proteins, like Solanic, are also used in food applications (Alting et al. Potatoes are a superior protein source relative to other vegetables and cereals because of their high nutritional quality (Seo et al. The total soluble protein content in the potato juice consists mainly of three groups: patatin (40–60 %), protease inhibitors (20–30 %) and other (high-molecular-weight) proteins (Pots et al. 1975 Holm and Eriksen 1980 Ralet and Guéguen 2000). The potato protein solution has been the subject of many studies to determine its composition and functional properties (Kapoor et al. Potato crops are not only grown for consumption, but also for starch production, with the starch extraction process yielding protein-rich waste water (Løkra and Strætkvern 2009). One of the most important crops worldwide is the potato ( Solanum tuberosum), accounting for about 45 % of the global tuber crop production (WCRTC 2016).
