Reduced-sodium roasted chicken: Physical/technological characteristics, optimized KCl-seasoning mixture, consumer perception, liking, emotions, and purchase intent.

For thousands of years, sodium chloride (NaCl) has been used as a preservative and flavor enhancer. In the organism, NaCl plays a role in nerve functions, osmotic pressure, and nutrient absorption. However, high consumption of NaCl could lead to health issues, such as hypertension and heart-related problems. For these reasons, potassium chloride (KCl) has been considered a salt substitute in foods, but KCl could be limited to food matrixes because of its unwanted bitterness and metallic aftertaste. As a result, the objective of this study was to analyze KCl-reduced-sodium roasted chicken in physical/technological characteristics, KCl-seasoning mixture, consumer perception, liking, emotions, and purchase intent (PI). An extreme vertice mixture design decided granulated garlic (74.09%), black pepper (9.95%), smoked paprika (14.47%), and KCl (1.39%) ratio of good seasoning-KCl mixture for roasted chicken based on sensory attributes used on the desirability function methodology. After optimizing the KCl-seasoning blend, NaCl/KCl replacement levels (0%, 25%, 50%, 75%, and 100%) were established and evaluated consumer perception, liking, emotions, and PI. Adding 25% and 50% of KCl showed no significant (p > 0.05) impact on the sensory attributes. Likewise, PI significantly (p < 0.05) increased when utilizing 25% and 50% of KCl after panelists received information about sodium health risks (SHR). Regarding emotional responses, unsafe and worried significantly (p < 0.05) decreased among the highest KCl replacement levels (75% and 100%) after panelists obtained the SHR. Overall liking, gender, age, salt user, and positive emotional responses (satisfied and pleased) were decisive predictors concerning PI among panelists.

Development of Gluten-Free Bread Using Teosinte (Dioon mejiae) Flour in Combination with High-Protein Brown Rice Flour and High-Protein White Rice Flour.

Gluten-free bread is an important product that is under development using different sources, such as rice and starchy plants. Teosinte seeds are utilized by ethnic groups in Honduras to produce gluten-free flour to prepare traditional baked goods and beverages. The quality of gluten-free products could vary depending on flour properties, such as amylose content, particle size, and water absorption capacity. A good strategy for developing baked goods is to mix different cereal grain sources to optimize their physicochemical properties. As a result, the current study aimed to develop bread from novel flours including teosinte (TF), high-protein brown rice (BRF), and high-protein white rice (WRF). Breads were analyzed for hardness, specific volume, and color utilizing a Simplex-Centroid mixture design coupled with the desirability function. Pasting, and rheological characteristics of the flours, were also analyzed. For flour characteristics, TF addition to BRF or WRF decreased the peak, trough, breakdown, setback, and final viscosities, which would result in a more stable bread and decrease the flow index of rice flour dispersions. BRF and WRF had similar pasting properties, except that BRF had a lower breakdown viscosity. For bread characteristics, TF addition to BRF or WRF increased the specific volume and hardness of the bread compared to rice flour alone. L* of the crust and crumb a* values were increased with greater TF in the mixture, whereas TF decreased the crust a*and b* values and crumb L* values when mixed with BRF or WRF compared to rice flours alone. WRF and BRF were similar in crumb color (L* and a*), except that BRF had greater crumb yellowness (b*). Teosinte flour can be used in combination with rice flour to produce bread with good quality.
