    The increased interest in functional foods has driven the search for natural ingredients with health benefits. In this context, the mushroom Hericium erinaceus (Lion's Mane) stands out for its content of bioactive compounds such as polysaccharides, beta-glucans, and antioxidants. However, its application in food matrices is still limited. The main problem addressed by this research was the lack of functional products made with extracts from this mushroom, and its objective was to develop a cookie enriched with Hericium erinaceus extract, evaluating its physicochemical, sensory, and nutritional properties. The methodology included obtaining the bioactive extract using two techniques: aqueous extraction and hydroalcoholic extraction. Both extracts were characterized by evaluating pH, total solids, polysaccharides, and antioxidant capacity. Subsequently, cookies were formulated incorporating each type of extract, and a sensory evaluation was carried out with 20 panelists using a 5-point hedonic scale. Finally, the best-accepted formulation was subjected to nutritional analysis to determine protein, fat, fiber, moisture, ash, and total carbohydrates. The results showed that the aqueous extract presented a higher content of polysaccharides and a suitable viscosity for incorporation into baked goods, while the alcoholic extract showed higher antioxidant activity, but lower sensory acceptance. The cookie made with the aqueous extract obtained 71.20 percent acceptance and a nutritional profile superior to that of a conventional cookie, highlighting its contribution of protein and fiber. It is concluded that the aqueous extract of Hericium erinaceus is a viable alternative for developing innovative functional products, contributing to added value in the food industry.

    Verbena (Verbena litoralis K.) is a species of flowering plant belonging to the Verbenaceae family and has been traditionally used in the medicinal field for many years due to its anti-inflammatory, antibacterial, and antioxidant properties, attributed to its bioactive compounds such as flavonoids, essential oils, tannins, and terpenoids. However, there are no scientific studies regarding its use in food products or its level of toxicity. This study aimed to identify the physicochemical, bromatological, and functional properties of verbena for its subsequent conversion into flour and the formulation of cookies with partial substitution of wheat flour (Triticum aestivum L.) in percentages of 0, 10, 15, and 20. The viscous properties of the flours were studied using a rotational viscometer (RVA). The cookies from the best treatment were selected based on sensory analysis. The results indicated that verbena flour is rich in protein (21,20 porcentaje), fat (2,46 porcentaje), and dietary fiber (33,72 porcentaje). Functional properties included bulk density (0,25 g/mL), water absorption capacity (1,65 g water/g sample), oil absorption capacity (1,1 g oil/g sample), emulsifying capacity (20,83 porcentaje), and gelation capacity (14,01 porcentaje). RVA analysis showed that its gelatinization and starch content present favorable properties; however, it will be necessary to complement it with raw material possessing adequate characteristics. Cookies with a 10 porcentaje partial substitution had the highest sensory acceptability in terms of color, flavor, and texture.

    Nowadays, the population's perspective on health and nutrition has changed radically due to the growing awareness of diseases resulting from poor nutrition. In this regard, lupin flour (Lupinus mutabilis) emerges as an interesting alternative ingredient for the development of functional foods due to its high protein and fibre content. This study formulated a functional cookie using lupin flour, and analysed the physicochemical, rheological and textural properties of both the flour and the cookie with the best acceptability, after performing a sensory acceptability evaluation and triangulating with the other cookie formulations. The flour revealed high protein (49.58 percent) and total dietary fibre (24.40 percent) content compared to wheat flour. The lupin flour cookie also had a remarkable protein percentage (26.31 percent) five times higher than commercial wheat flour cookies. In the texture analysis, it was found that the lupin flour gave the cookies more hardness and fracturability. Finally, rheological analysis at Mixolab indicated that lupin flour has comparable dough development (120 Nm) and swelling power (0.50 Nm) to wheat flour. The study suggests that the developed lupin flour cookie could be a possible snack alternative for coeliacs with high protein content and a pleasant level of acceptability for all types of consumers.

    Currently, the food industry has undergone a remarkable transformation to meet the demand for more nutritious and healthy products. This change has led to the development of cookies that include unconventional ingredients in their composition. The present research proposes an innovative solution by incorporating tender lupin flour (Lupinus mutabilis Sweet) and achira starch (Canna edulis Ker Gawl) to increase the protein and fiber content in the cookies. Initially, tender lupin flour was produced, and its physicochemical, nutritional, and microbiological aspects were analyzed, showing values comparable to those of dry lupin flour, making it suitable to produce nutritious foods. To leverage the nutritional potential of this legume, cookies were formulated by partially substituting wheat flour with tender lupin flour and achira starch in percentages of 10, 20 and 30. The cookies from the best treatment were determined through a sensory analysis, which evaluated bromatological quality, microbiological safety, and texture. This analysis revealed a significant increase in protein and fiber levels, a product free of microorganisms, and a texture with hardness and fracturability values of 4.22 N. Therefore, the incorporation of tender lupin flour and achira starch in the formulation of cookies not only meets rigorous quality standards but also offers outstanding sensory attributes. This advancement significantly contributes to the availability of healthier and more nutritious food options in the current market.

    Cookies are among the most popular and consumed products in Ecuador. However, the fast pace of life of consumers creates a need for foods that are easy to access, quick to consume, and benefit their health. Chia (Salvia hispanica L.) is a pseudocereal with diverse functional properties, named as a superfood for its high amount of protein, antioxidants, fiber and fatty acids, beneficial to humans. This study aims to solve this social problem by generating a cookie with a higher amount of protein, fiber, and vitamins. Three formulations were proposed with a partial substitution of 10 percent of wheat flour. The ingredients were mixed to form dough that was laminated and baked. The best formulation was determined through sensory analysis, and proximate and oxidative rancidity analyses were developed. Hardness and fracturability were measured between the treatments. Sensory analysis determined formulation 544 to be the best, highlighting significant differences in color and flavor attributes among the three types of cookies. Proximal analysis showed an increase in protein and fiber contents in the best formulation, indicating nutrient enrichment. Rheological analysis showed an increase in the hardness of treatment 197 compared to the other treatments. Finally, oxidative rancidity analysis determined a shelf life of 304 days in the best formulation with a microbiological analysis that guarantees the safety of the product during storage.

    Cookies are one of the most desired snacks for both children, youth, and adults. However, a large part of the biscuit industries makes their products from refined wheat flour, butter, highly caloric sweeteners and ingredients whose nutritional contribution is low. In this study, the elaboration of cookies from fig flour (Ficus carica) and oat flour (Avena sativa) using three types of sweeteners (panela, white sugar and erythritol) was proposed for young adults aged 18-25; with the purpose of providing a food with a sensory, physical, and nutritional composition that adapts to the requirements of consumers. For the development of the investigation, different formulations were used in relation to the proportions of fig flour (HH) and oat flour (HA) (30:70, 50:50 and 70:30), in addition to the type of sweetener (panela, sugar and erythritol). To determine the best treatment, sensory parameters (color, odor, taste, texture, and acceptability) were evaluated using an incomplete block design, and textural properties using a Brookfield texturometer. The best formulation obtained was a1b1 (30 percent HH, 70 percent HA and sweeteners). The proximal analysis of the best treatment was obtained: 2.90 percent moisture, 8.23 percent protein, 16.22 percent fiber, 20.77 percent fat, and an energy content of 419 kilocalories per-100 grams of product. The cookie could be an alternative to complement the diet of people between 18 and 25 years of age.
