As one of the post-COVID-19 response strategies, representative processed products derived from the natural plant material flaxseed and a dietary supplement fortified with female hormones (estrogens) were developed in Canada, an eco-friendly country was introduced. These products were: 1) flaxseed oil to help maintain cognitive and immune function, 2) Lignan50, a substance with effects similar to estrogen, a female hormone, 3) XanFlax, a thickener for confectionery/baking and egg substitute, 4) MediFlax, a constipation reliever, 5) SesaFlax, which has a fragrance similar to sesame, 6) Linusorb, which is effective for its pharmaceutical anti-inflammatory/anti-oxidation and anti-aging properties, and 7) LinuLyte, a water/electrolyte supplement containing high dietary fiber. It is expected that these dietary products will help maintain and promote health as part of a response to the COVID-19 pandemic.

Metal hydroxides and alkoxides are used as base catalysts for biodiesel production. When metalhydroxides are dissolved in alcohol, they produce water, which can react with triglycerides (TGs) andproduce free fatty acids (FFAs) rather than the desired fatty acid alkyl esters. Metal alkoxides are moreexpensive to produce and their transportation is hazardous. In this study, potassium alkoxide catalystswere synthesized from potassium hydroxide (KOH) solution and glycerol, which is by-product ofbiodiesel production process, by heating 50% KOH solution and glycerol at different mole ratios,temperatures and vacuum pressures. These operating parameters were optimized and their interactiveeffect on catalyst synthesis was studied by using response surface methodology (RSM). This study alsofocused on the development of a correlation relating the effects of these variables with drying behavior ofreagents during catalyst synthesis. The results indicated that KOH to glycerol mole ratio and vacuum pressure had the most significanteffects (P < 0.0001) on free water mass loss during catalyst synthesis. The optimum reaction conditionwas KOH to glycerol mole ratio of 2:1, reaction temperature 130 C and vacuum pressure 113 mbar. X-raypowder diffraction showed that glycerol derived alkoxide compounds were predominantly monopotassiumsubstituted alkoxides that occur as adducts with potassium hydroxide. The glyceroxidecatalyst prepared at 3:1 mole ratio of KOH:glycerol has improved biodiesel yield to that of conventionalpotassium methoxide (KOCH3) catalyst.

The purpose of this study was to provide basic data for future research and suggest product development and market segmentation strategies by identifying the perceptions and consumption behaviors of vegetarians in each segment of the vegetarian market. According to food consumption value, a total of three market segments were derived, and the markets were named based on their characteristics, including 'environment and animal protection', 'multiple consideration' and 'low interest'. As a result of analyzing the perception of vegetarian-based food, "environment and animal protection" and "multiple consideration" presented positive perceptions of a vegetarian food product. Conversely, the group stating low interest expressed negative perceptions of the vegetarian food product. An analysis of the requirements for development for vegetarian-based foods products (eg. aquafaba), indicated that the development requirements for all products, except cultured and processed meats, were high.?Considerable demand was observed for vegetarian menus and vegetarian restaurants. As a result of the analysis on the necessity of the elements of the vegetarian restaurant menu, the subjects that stated "multiple consideration" had significantly higher awareness of issues related to vegetarian foods than others.
