This study examined the textural and rheological properties of Algerian honeys and margarines formulated with honey and their sensory acceptance. Textural analysis shows that all honeys and margarines enriched with honey are spreadable, easy to swallow by the consumer and to adhere to a surface (bread, teeth, tongue, etc.), and have suitable adhesiveness. The hardness and elasticity values reveal that H5 honey and its M5 margarine are less hard and regain their height more quickly. The rheological analysis reveals that all honeys and formulated margarines non‐Newtonian behavior at 25 and 45°C with a G′ > G″ for each type of honey except for H1 and all margarines elaborated with honey presenting a structure of a gel. Statistical analysis shows no significant differences (p > 0.05) in mean values of activation energy, suggesting that honeys and margarines need the same energy to flow. Chemometric analysis reveals strong similarities between (H3 and H5) and (M3 and M5). Sensory acceptance of margarines enriched with honey shows that M4 and M5 margarines are the most preferred by consumers with a satisfaction rate between 60% and 80%. In conclusion, margarine formulated with honey should be introduced to the market due to their good structural properties and high acceptance.
