Blueberry-based gummies with partial substitution of unflavored gelatin for cushuro (Nostoc commune Vauch.) flour

Abstract

Cushuro (Nostoc commune Vauch.) is an alga resistant to adverse weather conditions and has been consumed since ancient times. However, in recent years, more research has been carried out to revalue this product since it has beneficial functional and nutritional characteristics. In the present study, cushuro is proposed as an alternative to improve a traditional and highly consumed product such as gummies, in addition to using blueberry (Vaccinium myrtillus Var. Biloxi) pulp. For this, partial substitutions of unflavored gelatin for cushuro flour were performed at 35% (T1), 45% (T2), 55% (T3). As a result, it was obtained that the higher the percentage of cushuro used, the protein and carbohydrate content increased reaching values of 3.85 ± 0.03 % and 91.58 ± 0.64% in dry basis, and the fat content decreased until 4.13 ± 1.15% in dry basis. On the other hand, by using cushuro flour and blueberry pulp, the antioxidant capacity of the gummies was increased (reaching > 60% inhibition of the DPPH radical). Finally, changes in the texture and color of the gummies were found by using cushuro flour. In conclusion, the use of raw materials little-explored can present a great alternative to improve the quality of traditional gummies.
