“…For brown and white sesame seeds, the maintained bioaccessibility of syringic acid could probably relate to the metabolism of gallic acid as syringic acid is the derivative of gallic acid. Furthermore, the oxidation of lignin could also produce some phenolic derivatives, including vanillic and syringic acid, which could be the reason for syringic acid generation (Khaneshi et al, 2013; Nasrollahzadeh et al, 2021). Compared to previous studies of other food ingredients with similar nutritional compositions, the bioaccessibility in our research was significantly higher and required more accurate investigation with dialysis membrane or cell lines.…”

Sesame (Sesamum indicum L.) is an oilseed crop and rich in various bioactive compounds including phenolics, phytosterols, and vitamins. In this study, phenolic compounds were extracted from three varieties of sesame seeds (black, brown, and white) to determine the antioxidant activities and bioaccessibility of selected phenolic compounds during in vitro digestion and colonic fermentation. The SCFAs production was also estimated. Black sesame seeds performed the highest total phenolic content (TPC) (2.69 mg GAE/g) and antioxidant capacities during gastrointestinal digestion. During colonic fermentation, black and brown sesame seeds exhibited relatively higher TPC (4.13 mg GAE/g) and antioxidant activities (DPPH: 8.6 mg TE/g; FRAP: 4.1 mg TE/g). Kaempferol was the lowest bioaccessible phenolic compound presented in all three sesame seeds, which relied more on the action of gut microbiota. White sesame seeds displayed higher production of individual and total SCFAs followed by black sesame seeds, which could be beneficial to gut health. Novelty impact statement Black and brown sesame seeds showed relatively higher content of phenolic compounds and remarkable antioxidant potential during in vitro gastrointestinal digestion and colonic fermentation. The bioaccessibility of phenolic compounds present in brown and white sesame seeds was relatively higher than in black sesame seeds. Most of the detected phenolic compounds in selected sesame seeds were fully bioaccessible after 24 h of colonic fermentation, except kaempferol. White and black sesame seeds showed higher production of SCFAs, which would be more beneficial to gut health.

“…In this procedure, the temperature typically falls within the range of 180-280 • C, while the pressure is maintained between 2-6 MPa, with a duration spanning from 5 to 240 min, as noted by Arellano et al (2016) [95]. In addition to being able to process biomass with a high moisture content without predrying, HTC also has low carbonization temperatures (180-350 • C), and it can minimize air pollution by dissolving nitrogen oxides and sulfur oxides in water [96]. Figure 12 summarizes the biomass conversion technologies that were mentioned in this section and Table 4 summarize the major difference between thermochemical and biochemical conversion.…”

With the global population continuing to increase, the demand for food and energy has escalated, resulting in severe environmental pressures. Traditional methods of food and energy production have left a significant footprint on the environment, primarily due to the emission of greenhouse gases and a notable surge in waste production. Nevertheless, scientists have recently focused on developing sustainable solutions by managing biomass waste and converting it into useful products. Various biomass conversion technologies, including pyrolysis, gasification, and fermentation, have emerged to transform waste materials into valuable commodities like biofuels, fertilizers, and chemicals. These technologies present an alternative to conventional energy production methods and decrease reliance on non-renewable resources. Furthermore, the by-products generated through biomass conversion, such as biochar, possess utility as valuable soil amendments. This review emphasizes the potential of biomass conversion technologies in providing sustainable solutions for waste management, food and energy production, and reducing negative environmental impacts while providing valuable by-products for agricultural use. The focus is on Lebanon, which is facing a waste and energy crisis, with an aim to encourage and promote sustainable practices by highlighting different green waste management technologies. Focusing on the application of biochar in soil, our goal is to provide cost-effective and eco-friendly solutions to various agricultural and environmental challenges in Lebanon. This includes using biochar from biomass waste as a soil amendment to boost crop yields, remediate soil pollution, reduce soil drought stress, and address other related issues.
