“…1. Already at the lowest temperature (130 °C), a decrease in total carbohydrate and furfu- Since the carbohydrate present in the sunflower seeds is mostly starch 15 and since the activation energy of starch hydrothermal degradation in subcritical water is quite low 2 , the obtained results were, as such, expected. For this reason, the carbohydrates (in this case starch) should, not be induced in subcritical water for too long, otherwise the concentration rapidly decreases to such a point where no more carbohydrates are present.…”

“…Slightly higher values were obtained for the Δ7‐STIG samples, with an average of approximately 300 g kg −1 against 230 and 250 g kg −1 obtained for Control and CAMP, respectively. According to Gunstone, 11 the mechanical extraction of sunflower oil can reach yields of between 700 and 800 g kg −1 of total oil. In the present study, the hybrid CAMP and Δ7‐STIG presented values between 710 and 730 g kg −1 of total oil.…”

BACKGROUND Phytosterols are plant components with health benefits. Oleaginous seed hybridization can be relevant to increase phytosterols in diet through enriched oils. Sunflower oils obtained by press (PO) and subsequent solvent extraction (SO) from three types of phytosterol‐enriched seeds were characterized. One presented a phytosterol composition of common sunflower seeds, whereas the other two were rich in campesterol and Δ7‐stigmasterol, respectively. Seeds from two different harvests, 2015 and 2017, were studied. RESULTS The type of extraction did not have a significant influence on the fatty acid composition. However, considerable differences were found between harvests. The oleic‐to‐linoleic ratio decreased from 0.71 in 2015 to 0.47 in 2017. The phytosterol compositions of the PO were similar to their SO homologues and no substantial differences were found between harvests. However, the SO presented higher total contents of phytosterols (4849–9249 mg kg−1) than the PO (2839–5284 mg kg−1) and the oils of 2017 showed higher levels (4476–9249 mg kg−1) compared to 2015 (2839–5754 mg kg−1). Unlike phytosterols, no significant differences were found in the tocopherol contents between the PO and SO or between harvests. The PO met Codex specifications for edible oils, except for trace metals, with concentrations close or above the limits for Cu, Fe, Pb and As. CONCLUSIONS Differences in environmental and/or cultivation conditions between harvests may result in substantial differences in the fatty acid composition and phytosterol content in oils from the new sunflower seeds. Rigorous measures and controls to avoid trace metal contamination are required so that the PO can be considered as edible virgin oils. © 2020 Society of Chemical Industry

“…Only high-oleic sunflower oil (HOSO) was known until a few decades ago. Newer sunflower hybrids yielding oils with high oleic acid content became available on the market more recently [ 187 ]. Crossover or parallel feeding studies ranging from 2.5 to 8 weeks with sunflower oil as a discerned source of fat in the diet showed increased levels of linoleic acid in plasma lipid fractions, platelets, and subcutaneous adipose tissue at the end of the intervention [ 157 , 173 , 178 – 180 , 188 ].…”

Biomarkers of food intake for nuts and vegetable oils: an extensive literature search

et al. 2019

Nuts and vegetable oils are important sources of fat and of a wide variety of micronutrients and phytochemicals. Following their intake, several of their constituents, as well as their derived metabolites, are found in blood circulation and in urine. As a consequence, these could be used to assess the compliance to a dietary intervention or to determine habitual intake of nuts and vegetable oils. However, before these metabolites can be widely used as biomarkers of food intake (BFIs), several characteristics have to be considered, including specificity, dose response, time response, stability, and analytical performance. We have, therefore, conducted an extensive literature search to evaluate current knowledge about potential BFIs of nuts and vegetable oils. Once identified, the strengths and weaknesses of the most promising candidate BFIs have been summarized. Results from selected studies have provided a variety of compounds mainly derived from the fatty fraction of these foods, but also other components and derived metabolites related to their nutritional composition. In particular, α-linolenic acid, urolithins, and 5-hydroxyindole-3-acetic acid seem to be the most plausible candidate BFIs for walnuts, whereas for almonds they could be α-tocopherol and some catechin-derived metabolites. Similarly, several studies have reported a strong association between selenium levels and consumption of Brazil nuts. Intake of vegetable oils has been mainly assessed through the measurement of specific fatty acids in different blood fractions, such as oleic acid for olive oil, α-linolenic acid for flaxseed (linseed) and rapeseed (canola) oils, and linoleic acid for sunflower oil. Additionally, hydroxytyrosol and its metabolites were the most promising distinctive BFIs for (extra) virgin olive oil. However, most of these components lack sufficient specificity to serve as BFIs. Therefore, additional studies are necessary to discover new candidate BFIs, as well as to further evaluate the specificity, sensitivity, dose-response relationships, and reproducibility of these candidate biomarkers and to eventually validate them in other populations. For the discovery of new candidate BFIs, an untargeted metabolomics approach may be the most effective strategy, whereas for increasing the specificity of the evaluation of food consumption, this could be a combination of different metabolites.Electronic supplementary materialThe online version of this article (10.1186/s12263-019-0628-8) contains supplementary material, which is available to authorized users.
