“…The nutritional value of food products is determined by their chemical composition (Table 1). Dry matter (DM) amounts to 16.5-36.2% of Helianthus tuberosus tuber mass (7,9,25). According to other authors, DM ranges from 20.5-28.1% (25).…”

“…Chlorogenic acid, 3,5-, 3,4-, 1,5-caffeoylquinic acids, and neochlorogenic acid had the strongest influence on antioxidant potential measured by the ABTS on-line profiling method. Nevertheless, the polyphenolic compounds are stress metabolites, and their content in the plants can be modified by fertilisation; so, this aspect should be considered in order to provide a thorough recommendation for a single polyphenolic component (5,25,(63)(64). This proves a potential possibility of using these raw materials in human and animal nutrition and in preparation of healthy food products.…”

Identifying the nutritional and health properties of Helianthus tuberosus, and learning more about this valuable species. It is believed that increased consumption of Jerusalem artichoke (JA) products is related to low blood pressure. One of many questions to answer is whether supplementation of inulin and inulin derivatives obtained from Helianthus tuberosus tubers and aerial parts can be used as antidiabetic, anti-carcinogenic, anti-fungistatic, anti-constipation, body mass-reducing, metabolism-improving agents. We ran a search in Medline,

“…The biological value of Jerusalem artichoke tubers is determined by the genetic characteristics of cultivars and the applied production technology [28,[30][31][32][33][34]. Fertilization, in particular potassium fertilization, is an agricultural treatment that exerts the greatest impact on the biological value of tubers.…”

The aim of this study was to determine the effects of soil potassium fertilization (150, 250 and 350 kg K2O ha−1) and irrigation on the tuber quality (content of ά-tocopherol, β-carotene, essential and endogenous amino acids) of three Jerusalem artichoke (Helianthus tuberosus L.) cultivars (Topstar, Violette de Rennes, Waldspindel). Jerusalem artichokes were grown during a field experiment in the Agricultural Experiment Station in Tomaszkowo (53°42′ N, 20°26′ E, north-eastern Poland). The content of ά-tocopherol and β-carotene was determined at 1.60–2.65 and 0.75–1.00 mg kg−1 DM, respectively, in all Jerusalem artichoke cultivars produced in north-eastern Poland. High rates of potassium fertilizer (250 and 350 kg K ha−1) increased the content of ά-tocopherol in tubers by 47% and 66% on average, respectively. The stimulatory effects of high potassium rates on the content of ά-tocopherol (2.5-fold increase) were observed only in response to irrigation. High rates of potassium fertilizer induced a particularly high increase (3.2-fold) in ά-tocopherol concentrations in Jerusalem artichokes cv. Waldspindel. Irrigation increased ά-tocopherol levels (by 40%) and decreased the concentrations of β-carotene (by 25%) and most essential and endogenous amino acids (isoleucine, leucine, lysine, phenylalanine, valine, alanine, glycine, histidine, serine, threonine). The Topstar cultivar accumulated the highest quantities of essential and endogenous amino acids. Leucine, methionine + cysteine were the limiting amino acids in Jerusalem artichoke tubers. The analyzed tubers were characterized by very high nutritional quality of dietary protein (Essential Amino-Acid Index, 66–78).
