Item Sensory Acceptance, Appetite Control and Gastrointestinal Tolerance of Yogurts Containing Coffee-Cascara Extract and Inulin(Nutrients, 2020) Iriondo De Hond, Amaia; Herrera, Teresa; Fernández-Fernández, Adriana Maite; Sorzano, Carlos Oscar S.; Miguel Casado, Eugenio José; Castillo, María Dolores del; Iriondo-Dehond, M.The improvement of the nutritional quality of dairy foods has become a key strategy for reducing the risk of developing diet-related non-communicable diseases. In this context, we aimed to optimize the concentration of inulin in combination with 10 mg/mL of coffee-cascara extract in yogurt while considering their effect on appetite control, gastrointestinal wellbeing, and their effect on the sensory and technological properties of the product. For this purpose, we tested four coffee-cascara yogurt treatments in a blind cross-over nutritional trial with 45 healthy adults: a coffee-cascara yogurt without inulin (Y0) and coffee-cascara yogurts containing 3% (Y3), 7% (Y7), and 13% (Y13) of inulin. The ratings on sensory acceptance, satiety, gastrointestinal tolerance, and stool frequency were measured. Surveys were carried out digitally in each participant’s cellphone. Yogurt pH, titratable acidity, syneresis, and instrumental texture were analyzed. Inulin addition increased the yogurt’s firmness and consistency. Y13 achieved significantly higher overall acceptance, texture, and taste scores than Y0 (p < 0.05). Y3 presented similar gastrointestinal tolerance to Y0. However, 7% and 13% of inulin produced significant (p < 0.05) bloating and flatulence when compared to Y0. The appetite ratings were not significantly affected by the acute intake of the different yogurts. Overall, Y3 was identified as the formulation that maximized nutritional wellbeing, reaching a “source of fiber” nutritional claim, without compromising its technological and sensory properties.Item Enhancement of the Antioxidant Capacity of Thyme and Chestnut Honey by Addition of Bee Products(Foods, 2022) Sánchez Martín, Vanesa; Morales Gómez, Paloma; Gonzalez-Porto, Amelia V.; Iriondo De Hond, Amaia; Lopez-Parra, Marta B.; Del Castillo, Maria Dolores; Fernández Hospital, Xavier; Fernández Álvarez, Manuela; Hierro Paredes, Eva; Haza Duaso, Ana IsabelHoney consumption and imports have increased in recent years, and it is considered by consumers to be a healthy alternative to more commonly used sweeteners. Honey contains a mixture of polyphenols and antioxidant compounds, and the botanical origin and geographical area of collection play an important role in its chemical composition. The present study investigated the physicochemical properties, total phenolic content, and antioxidant capacity of Spanish thyme honey and chestnut honey, and their mixtures with royal jelly (2% and 10%) and propolis (2% and 10%). The analysis of the physicochemical parameters of both honey samples showed values within the established limits. Propolis showed the highest value of total phenolic content (17.21–266.83 mg GAE/100 g) and antioxidant capacity (DPPH, ORAC, and ABTS assays; 0.63–24.10 µg eq. Tx/g, 1.61–40.82 µg eq. Tx/g, and 1.89–68.54 µg eq. Tx/g, respectively), and significantly reduced ROS production in human hepatoma cells. In addition, mixtures of honey with 10% of propolis improved the results obtained with natural honey, increasing the value of total phenolic content and antioxidant capacity. A significant positive correlation was observed between total phenolic compounds and antioxidant capacity. Therefore, the antioxidant capacity could be attributed to the phenolic compounds present in the samples, at least partially. In conclusion, our results indicated that thyme and chestnut honey supplemented with propolis can be an excellent natural source of antioxidants and could be incorporated as a potential food ingredient with biological properties of technological interest, added as a preservative. Moreover, these mixtures could be used as natural sweeteners enriched in antioxidants and other bioactive compounds.Item Validation of coffee by-products as novel food ingredients(Innovative Food Science and Emerging Technologies, 2018) Iriondo De Hond, Amaia; San Andrés Larrea, Manuel Ignacio; Sánchez-Fortún Rodríguez, Sebastián; Aparicio García, Natalia; Fernández-Gómez, Beatriz; Guisantes-Batán, Eduardo; Velázquez Escobar, Francisco; Blanch, Gracia Patricia; Castillo, María Dolores delThis research aimed to validate coffee husk, parchment and silverskin as new health-promoting food ingredients. Characterization of the novel ingredients was carried out by Raman and infrared spectroscopy and analysis of total phenolic compounds, chlorogenic acid, caffeine and dietary fiber. Antioxidant properties of the novel ingredients were tested by ABTS and intracellular ROS formation in HepG2 cells. Pesticides, mycotoxins, acrylamide and acute toxicity experiments following OECD Test Guidelines 425 were performed to assess the food safety of extracts, solid residues and raw materials. Husk and silverskin are proposed as a source of two food ingredients: aqueous extracts enriched in phytochemicals and antioxidant dietary fiber while parchment is proposed as a natural source of antioxidant dietary fiber. No lesions were found in selected isolated vital organs from treated animals. Coffee by-products can be converted into safe food ingredients allowing a whole food waste recovery. Analyses of contaminants are essential for achieving this goal.
