Amlou inspired spread: Formulation and characterization of new spread based on Ziziphus lotus L. fruit, argan oil, and honey

This study explores novel applications of combining natural products by integrating Ziziphus lotus L. (Z. lotus), honey, and argan oil to create a product similar to traditional Moroccan Amlou (a mixture of almonds, honey, and argan oil). Five formulations were developed with varying percentages of these three ingredients, alongside two formulations of traditional Amlou. The nutritional value, mineral composition, fatty acid profile, bioactive compounds, and antioxidant activities of the products were analyzed using standard analytical methods such as gas chroma- tography and spectrophotometry. Additionally, sensory evaluations were conducted to assess consumer preferences. The results showed that the new formulations are rich in oil (45.15–52.24 g/100 g), carbohydrates (40.26–46.81 g/100 g), and protein (3.15–3.92 g/100 g). Mineral analysis revealed significant amounts of potassium (443–578 mg/100 g), calcium (98–124 mg/ 100 g), phosphorus (50–65 mg/100 g), and magnesium (38–50 mg/100 g). The Z. lotus-based products exhibited higher phenolic content (7–12 mg GAE/g), flavonoids (7.10–10.18 mg QE/g), and stronger antioxidant activities using DPPH radical scavenging activity (3.55–11.14 mg AAE/ g) and FRAP (5.39–8.55 mg AAE/g). Moreover, the new product retains the beneficial fatty acid profile of argan oil, with a high content of oleic acid (48 %) and linoleic acid (32 %). Sensory evaluation indicated that the formulation consisting of 45 % Z. lotus powder, 50 % argan oil, and 5 % honey was the most appreciated for taste and texture. These findings suggest that incorpo- rating Z. lotus into traditional Amlou recipes not only enhances nutritional and antioxidant properties but also meets consumer acceptance in terms of flavor and texture.
