Plant-Based Proteins for Barbecue
Plant-based options, including products made from soy, peas, mushrooms, and other plant sources, have seen significant advancements in recent years. The development of plant-based barbecue products, such as burgers, sausages, and skewers, have been long established in terms of their sensory attributes and nutritional profiles to ultimately satisfy consumer demand and preferences.
SFA had established a novel food regulatory framework that necessitates the food industry players to conduct pre- market assessment for novel food like the alternative protein products that is not pre-dominantly consumed as food) [5]. An interesting systematic review performed by Romão B [6] compared the nutritional profiles of commercialized plant- based meat. As a result, they discovered that the carbohydrate content of these products is higher than that of their protein counterparts. Besides, they also found out that the sodium concentrations within these meat substitute products are present in excessive amount and thus they suggested sodium-free alternatives as a solution to the concern of high sodium intake by the consumers, especially during barbecue dining. Table 2 presents the plant-based food suitable for barbecue dining.
