“…Indeed, linoleic and oleic acids represent respectively 52.69% and 18.14%. However, there are slight differences in the composition of fatty acid compositions with those reported by Cuco et al (2019). Linoleic and oleic acids represent from 49.4 to 55.4 and from 23.4 to 27.0, respectively.…”

Oilseed pumpkin seeds are known to be rich in oil and nutrients. Their content in bioactive components gives them some assets that make them beneficial for human health. Although commonly consumed as a snack, pumpkin seeds are ready to claim more uses. The identification of pumpkin species is a major resource in this study. Thus, we worked with three pumpkin species: Cucurbita maxima (CMa), Cucurbita moschata (CMo) and Cucurbita pepo (CP). The species effect on the chemical composition, the content of bioactive compounds and the antioxidant activity was studied. As a result, the analysis of pumpkin seed oil revealed a polyunsaturated fatty acids (PUFAs) content ranging from 52.23% to 57.65%. Our study also revealed that this oil was a good source of phenolic compounds, in particular CMa with a value of 27.52 mg gallic acid equivalents per gram of methanolic extract and 633.51 mg/kg of total tocopherols, which gives it a very strong antioxidant character. In addition, it showed a high antioxidant potency (126.20 ± 20.44) μg/ml for CMa. In this respect, it can be said that the species effect can be a very important factor influencing the nutritional quality of pumpkin seed oil.

“…Contrary to other plant foods, specialty seeds contain different patterns of carotenoids, such as chia seed (β‐carotene, 9‐cis‐β‐carotene, and lutein) (Dabrowski et al., 2018), black cumin seed (β‐carotene) (Ramadan & Moersel, 2006), flaxseed (α‐carotene, β‐carotene, and zeaxanthin) (Tańska et al., 2018; Teh & Birch, 2013), hemp seed (β‐carotene) (Oomah et al., 2002), perilla seed (lutein) (Pan et al., 2020), pumpkin seed (β‐carotene, β‐cryptoxanthin, lutein, and zeaxanthin) (Akin et al., 2018; Can‐Cauich et al., 2019; Cuco et al., 2019b; Górnaś et al., 2014; Parry et al., 2006; Tuberoso et al., 2007), quinoa seed (β‐carotene, lutein, and zeaxanthin) (Tang, et al., 2016), and sesame seed (β‐carotene) (Górnaś et al., 2014; Tuberoso et al., 2007).…”

“…Among the eight specialty seeds listed in Table 4, the levels of total carotenoids range from tr‐0.04 mg/100 g to 0.25 to 59.30 mg/100 g, being lowest in sesame seed oil and highest in black cumin seed oil (Akin et al., 2018; Can‐Cauich et al., 2019; Chen et al., 2019a; Cuco et al., 2019b; Dabrowski et al., 2018; Górnaś et al., 2014; Kim & Choe, 2013; Oomah et al., 2002; Pan et al., 2020; Parry et al., 2006; Ramadan & Moersel, 2006; Tang et al., 2016; Tańska et al., 2018; Teh & Birch, 2013; Tuberoso et al., 2007). Specialty seed oils generally contain higher amounts of carotenoids than that of nut oils (except pistachio oil) (Alasalvar et al., 2020b).…”

Seeds play important roles in human nutrition and health since ancient time. The term “specialty” has recently been applied to seeds to describe high‐value and/or uncommon food products. Since then, numerous studies have been conducted to identify various classes of bioactive compounds, including polyphenols in specialty seeds. This review discusses nutrients, fat‐soluble bioactives, polyphenols/bioactives, antioxidant activity, bioavailability, health benefits, and safety/toxicology of commonly consumed eight specialty seeds, namely, black cumin, chia, hemp, flax, perilla, pumpkin, quinoa, and sesame. Scientific results from the existing literature published over the last decade have been compiled and discussed. These specialty seeds, having numerous fat‐soluble bioactives and polyphenols, together with their corresponding antioxidant activities, have increasingly been consumed. Hence, these specialty seeds can be considered as a valuable source of dietary supplements and functional foods due to their health‐promoting bioactive components, polyphenols, and corresponding antioxidant activities. The phytochemicals from these specialty seeds demonstrate bioavailability in humans with promising health benefits. Additional long‐term and well‐design human intervention trials are required to ascertain the health‐promoting properties of these specialty seeds.

In this study, extraction yield of valuable compounds from brewer's spent grain (BSG) using pressurized liquid extraction (PLE) was investigated varying temperature, solvent type, and flow rate at a constant pressure. The results were compared with Soxhlet extractions using the total phenolic compounds (TPC), total flavonoid compounds (TFC), antioxidant activity (AA), reducing sugars (RS), and total reducing sugars (TRS) as indices. The highest PLE extraction yield was 20.1 wt%, at 120°C, 2 mL/min using ethanol to water volume ratio of 0.5, at 10 MPa. The TPC, TFC, and AA content were favored by water and water/ethanol extractions and temperature increase. The highest AA was obtained with water at 120 °C and 4 mL/min achieving 9944, 4769 and 4096 µmol TE/100 g of BSG extract, respectively. PLE was capable of present high extraction yields maintaining the RS and TRS in the BSG matrix. In addition, BSG was defatted with compressed propane before the extraction with PLE, showing that 2 compressed propane is highly efficient in recovering the lipid fraction from BSG. The results demonstrated a great potential of water and different EtOH/Water solvent ratio at pressurized conditions for obtaining bio-compounds of BSG in a crude extract with expressive biological activity.
