Abstract

Aleppo pine seeds are a potential candidate for the production of nondairy milk due to their high protein (26%) and lipid (37%) content and their availability. For the first time, this study presents the implementation of a manufacturing scheme from seeds to final product, including pre-extraction, extraction, and post-extraction (physical and microbiological stabilization), using a 2(7-4) fractional factorial screening design. The seven factors were seed soaking time, grinding time, temperature and seed/water ratio during extraction, xanthan gum concentration, homogenization pressure, and pasteurization temperature. Beverage quality analysis consisted of measurements of chemical composition, color, stability, and rheological behavior. The results of experimental design showed that the dry matter as well as the lipid and protein contents increased significantly by increasing the ratio (grain/water) and the grinding time. On the other hand, the extraction temperature led to a better extraction of lipids but a lower extraction of proteins. Regarding stability, xanthan gum had a negative effect, while homogenization pressure and pasteurization temperature showed their effectiveness in decreasing the particle size and increasing the physical stability of the product.
