“…Selected specialty seed oils contain different patterns and amounts of tocols, predominantly γ‐tocopherol (Akin et al., 2018; Czaplicki et al., 2011; Dabrowski et al., 2018; Ghaleshahi et al., 2020; Górnaś et al., 2014; Jung et al., 2012; Kiczorowska et al., 2019; Kiralan et al., 2019; Montserrat‐de la Paz et al., 2014; Mufari et al., 2020; Özcan, 2019b; Przygoda & Wejnerowska, 2015; Ramadan et al., 2012; Rezig et al., 2012; Stevenson et al., 2007; Xu et al., 2020). Some specialty seed oils have been reported to contain small amounts of tocotrienols, such as chia seed (β and γ) (Özcan et al., 2019b), flaxseed (δ) (Ghaleshahi et al., 2020), perilla seed (α and δ) (Ghaleshahi et al., 2020), and pumkin seed (α, β, and γ) (Akin et al., 2018).…”

“…These phytosterols vary considerably among the eight specialty seeds. Data on each phytosterol level and pattern of eight specialty seed oils have been extensively reported (Akin et al., 2018; Can‐Cauich et al., 2019; Chen, 2019a; Ciftci et al., 2012; Cuco, 2019a; Dabrowski et al., 2018; Ghaleshahi et al., 2020; Hosseinian et al., 2004; Montserrat‐de la Paz et al., 2014; Ramadan & Moersel, 2006; Rezig et al., 2012; Tańska et al., 2018; Torri et al., 2019; Xu et al., 2020). Therefore, detailed patterns and levels of phytosterols in specialty seed oils are not provided in this review.…”

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.

Cucurbitaceae family seeds are mostly discarded as agro‐industrial wastes. Gurum (Citrullus lanatus var. colocynthoide) is an underutilized wild cucurbit plant, closely related to desert watermelon, which is grown abundantly in some African countries. Gurum seeds can play a significant role in health and nutrition due to their high oil content. This review describes the nutritional composition of gurum seeds and their oil profile. Gurum seeds are a good source of oil (27–35.5%), fiber (26–31%), crude protein (15–18%), and carbohydrates (14–17%). Gurum seeds oil is extracted by supercritical CO2 (SFE), screw press, and solvent extraction techniques. The gurum seeds oil is composed of unsaturated fatty acids with a high proportion of linoleic acid (C18:2) and oleic acid (C18:1). Gurum seeds oil contains various bioactive compounds, such as tocopherols, phytosterols, and polyphenols. It is reported that solvent extraction gives a higher yield than the screw press and SFE, but the SFE is preferred due to safety issues. More studies are required for producing better quality gurum seeds oil by using novel extraction techniques that can increase oil yield.

“…In this study which carried out by Akın [19] the contents of fatty acids, phytosterols, squalene, phenolic compounds and acids, carotenoids and phenolic bioactive substances and free radical scavenger antioxidant activities were determined from the raw pumpkin seeds grown in four different central Anatolia regions of Turkey. The oils extracted with cold press extraction method at 40 rpm and 40 °C were drained and left to collapse for 1 day at the temperature below 15 °C (sedimentation) in brown bottles, then sedimentation was removed and centrifuged for 20 minutes at 10 °C and kept at +4 °C (refrigerated) until analysis.…”

Introduction. The aim of this review is to explain the working principle of the cold press machine and discuss the effect of the extraction efficiency. The advantages and disadvantages of the extraction by means of cold press were explained by referring to other extraction methods. Material and method. The oil extraction from oilseeds by cold press method investigated for this study. The studies related with cold press were examined and the comparison of cold press with other methods used in oil production from oily seeds was compiled. Results and discussion. Cold press extraction is one of the methods of mechanical extraction as well as required less energy than other oil extraction techniques and also environmental friendly. It is used to extract oil from a range of matrices and is produced especially in the oil production from oilseeds. High-quality oils can be obtained by performing production at low temperatures using cold press method. It has an environmentally friendly use with no solvents. In other words, the cold-press extraction does not involve either heat or chemical extraction. The soybean, sunflower, rapeseed, corn, grapeseed, hemp, flaxseed, rice bran, olive and pumpkin oils were obtained by cold press extraction method. Moreover, these oils are interesting for consumers due to their natural and safe as well as prevent certain diseases and improve human health due to including a higher level of lipophilic phytochemicals such as antioxidants. These oils have better nutritive properties than refined oils. However, they have a lot of advantages, one of the disadvantages of this technique is low productivity. Another disadvantage of this technique is hard to extract same quality product. The cold pressed oils can add to food as natural antioxidative additives due to phytochemicals and as fatty acid supplements due due to invaluabile double bond fatty acid. There are several studies to investigate the other chemical compounds in the oils and try to use in food products. Conclusion. While observing the studies, it was generally focused on cold press extraction.
