“…Madiwale et al (2011) reported an increase in the concentrations of chlorogenic acid, caffeic acid and sinapinic acid in potato tubers stored for 90 days at a temperature of 3°C. Galani et al (2017) demonstrated that the levels of total phenolic compounds increased and then decreased in potato tubers stored at room temperature (25-32°C). The cited authors observed fluctuations in the content of phenolic compounds throughout storage at 4 and 15°C, which was higher on the last day of observation than on the first day.…”

The aim of this study was to evaluate the influence of cultivar and biostimulants on the health status of potato tubers after harvest and after 5 months of storage. The fungal pathogens isolated from potato tuber were cultured on PDA. The biostimulants limited the symptoms of dry rot in cv. Satina after harvest, in stored cv. Irga (Bio-Algeen S-90) and cv. Blaue St. Galler (Kelpak SL). The symptoms of common scab were reduced in stored potatoes cv. Satina in the Asahi SL treatment and the symptoms of late blight in stored potatoes cv. Satina in the Kelpak SL and Trifender WP treatment and in cv. Valfi in the Bio-Algeen S-90 and Kelpak SL treatment. Asahi SL and Kelpak SL decreased the severity of black scurf in stored potatoes cv. Irga. Biostimulants decreased the occurrence frequency of the causative agents of dry rot and black scurf after harvest. Total chlorogenic acid, which is predominant in potato tubers, was present in higher concentrations in the skin than in the flesh. Potato tubers had the highest content of 5-caffeoylquinic acid, followed by neochlorogenic acid (3-caffeoylquinic acid) and cryptochlorogenic acid (4-caffeoylquinic acid). Higher concentrations of chlorogenic acid were found in potato cultivars with blue-purple-and red-colored flesh than in those with yellow-and cream-colored flesh, and in response to the application of the Asahi SL biostimulant and Trifender WP.

Potato tubers prepared with no or low fat addition contain also important levels of bioactive compounds and antioxidants [4–8], including phenolic acids (mainly chlorogenic acid, content from 49 to 1400 mg kg -1 DM [9–10], ascorbic acid [4, 11–13], and flavonoids (ranging from 200–300 mg kg -1 FM), which are phytochemicals helping to reduce the risk of several diseases, such as cardiovascular diseases (CVD) via cholesterol reduction, inflammatory pathways, and cancer [4–18].…”

Antioxidant properties of potato tubers (Solanum tuberosum L.) as a consequence of genetic potential and growing conditions

The concentrations of the bioactive compounds in potato tubers are determined by both genetic potential and environmental factors. The purpose of the experiment was to determine the influence of organic and integrated production on the expression of the genetic potential with respect to the antioxidant properties of potato tubers and to evaluate its stability under different environmental conditions. This phenotyping was performed on seven new breeding lines (tetraploid clones) and three modern cultivars: Jelly, Satina and Tajfun. The results indicated that production system and location significantly influenced the antioxidant capacity measured by FRAP method. Organic farming and the location Chwałowice were characterized by higher values. Furthermore, anitioxidative capacity measured by FRAP method was correlated with chlorogenic acid content (r = 0.590**) and glutathione fractions, especially with the reduced form (GSH, r = 0.692**). Multidimensional comparative analysis (MCA) proved a better development of antioxidant properties of potato tubers in the organic cultivation system when compared with the integrated. Especially favorable were growing conditions at Boguchwała (organic) and worst at Młochów (integrated). From all investigated varieties, the best antioxidant properties were found in ‘Satina’ and ‘Jelly’. Clones TG-97-403 and 13-VIII-45 developed the weakest health promoting traits.

“…Следует отметить, что увеличение содержания антоцианов в клубнях не происходит при хранении при температуре выше 4°С. Многие данные указывают на увеличение суммарного содержания фенольных соединений при хранении при низких температурах, но только у картофеля с цветной мякотью [28,29]. Увеличение содержания антоцианов в клубнях рассматривается с точки зрения увеличения содержания в них сахаров при хранении в холодильнике.…”

Антиоксидантная активность пигментированного картофеля (Solanum tuberosum L.), содержание антоцианов, их биосинтез и физиологическая роль РЕЗЮМЕ Актуальность. Сорта картофеля с красной и фиолетовой мякотью представляют высокую диетическую ценность, так как являются источниками полифенольных соединений с антиоксидантной активностью, прежде всего антоцианов. Установлено, что содержание антоцианов у картофеля коррелирует с суммарным содержанием растворимых фенольных соединений и антиоксидантной активностью. Эти показатели значительно выше у картофеля с пигментированной кожурой и мякотью. При холодном хранении такого картофеля содержание фенольных соединений, в частности антоцианов, увеличивается. Пигментированный картофель также является более предпочтительным для потребления в пищу и промышленной переработки, так как в ходе этих процессов сохраняет антиоксидантные свойства и улучшает качество конечных продуктов. Селекция картофеля по признаку окраски мякоти и биотехнологические подходы регуляции накопления антоцианов базируются на понимании молекулярно-генетических процессов их биосинтеза. Биосинтез антоцианов включен в фенилпропаноидный метаболический путь и находится под контролем комплекса MBW, который включает в себя транскрипционные факторы MYB, bHLH и WD40. У картофеля был идентифицирован ряд генов, принадлежащих комплексу MYB. Ключевая роль в изменчивости по признаку пигментации в данный момент отводится гену StAN1. Имеются обширные данные о защитной роли антоцианов в ответ на различные типы стресса у картофеля. Ключевые слова: Solanum tuberosum L., антиокисдантная активность, фенольные соединения, антоцианы, комплекс MBW. Antioxidant activity of potatoes (Solanum tuberosum L.) and anthocyanin content, its biosynthesis and physiological role ABSTRACT Relevance. Potatoes with red and purple flesh are highly valued dietary products and sources of polyphenolic compounds with antioxidant activity, especially anthocyanins. It has been found that the anthocyanin content in potatoes correlates with the total soluble phenolic content and antioxidant activity. These measures are significantly higher for coloured potatoes. The total phenolic content in particular the total anthocyanin content increases during the cold storage of coloured potatoes. Pigmented potatoes are also more preferable for food and industrial processing because of retaining of antioxidant properties and improving of final products quality. Сoloured potatoes selection and biotechnological approaches of regulation of anthocyanins accumulation are based on the understanding of the molecular genetic processes of anthocyanins biosynthesis. The anthocyanin biosynthesis is a part of the phenylpropanoid metabolic pathway. It is controlled by the MBW complex. The MBW complex includes the transcription factors MYB, bHLH, and WD40. A number of the MYB complex genes have been identified in potatoes. The key role in potatoes pigmentation variability is currently assigned to the StAN1 gene. According to available data anthocyanins play a protective role in res...
