Abstract-From sesame, it is possible to obtain a creamy paste, which could represent a solution to the problem of wasteful production of this oilseed. In view of the above, the sensory quality of sweetened sesame paste formulated with added bovine blood plasma as a surfactant for possible use in confectionery was assessed in the present investigation. A completely randomized experimental design was used, under a multilevel 2x2x4 factorial structure at half fraction to rule out effects of similar treatments. It was evaluated the effect of factors (80 and 70% sesame paste, syrup (water + sugar + glucose) at 20 and 30% and bovine blood plasma at 0.75,1.0,1.25 and 1.5%) on the sensory responses of the 8 formulations. The sensory evaluation of the different treatments was carried out through preference and acceptance tests; the treatment with 70% of paste, 30% syrup and 1% plasma was the most widely accepted. The best treatment was T2 followed by T6. T8 showed significant differences in the parameters evaluated when compared to other treatments, and in turn had the lowest acceptance in the evaluated attributes. In general, treatments with a higher percentage of syrup had greater preference and acceptance for the same blood plasma content. In addition, 1% plasma is sufficient in the formulation of the paste, and higher concentrations make it perceptible, making the consumer reject the product.Keyword-Sesamumindicum L., Blood Plasma, Surfactant, Sensory Analysis. I. INTRODUCTION Sesame, known in Colombia as sesame (Sesamumindicum L.) is considered a food of importance in human nutrition [1]. At present, these seeds are mainly used for the production of oils [2-10], but they can also be used for the production of oily pastes [1,11] and other types of formulations [11][12][13].From sesame seed it is possible to obtain a rich paste using technological processes, including conditioning, husking, roasting and milling [12]. Sesame paste has a high nutritional value, as it is rich in lipids (between 54 % and 65 %), proteins (between 17 % and 27 %), carbohydrates (between 6.4 % and 21 %), dietary fibre (approximately 9%), niacin (approximately 4.5 mg 100 g ) [1,14,15]. It should be highlighted that Colombia is the third largest sesame seed producer in Latin America. It is cultivated in the departments of Magdalena, Bolívar, Sucre, Córdoba and Tolima, but there are currently no production policies in place to prevent post-harvest losses and increase their added value [16]. A product derived from sesame seeds, which is highly acceptable to the Colombian population, especially on the Caribbean coast, is sesame paste [1,15], which is a nationally indigenous product produced under the name of tahini in other parts of the world [11]. As it is a product derived directly from the milling of the seed, it is used as an ingredient for creamy desserts and sauces [1,12,14], so there are options to take advantage of the sesame production chain.On the other hand, there is currently an important demand for raw materials with a high nutritiona...
