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

Abstract

AbstractFor 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.
