Production and Characterization of Sumac PlantCrystals: Influence of High-Pressure Homogenization on Antioxidant Activity of Sumac (Rhus coriaria L.)

Oxidative stress diseases are usually treated or prevented by using antioxidants from natural artificial sources. However, as a sustainable source of phytochemicals, plants got renewed interest in obtaining their active agents green extraction technologies, i.e., techniques that reduce energy consumption, use renewable sources and result less post-extraction wastes. The high-pressure homogenization (HPH) technique was introduced into the food industry since it invented 1900 to homogenize milk later produce fruit juices with longer shelf-life without preservatives. Recently, HPH an eco-friendly method nanomill for improved efficacy organic solvents. In this study, sumac used antioxidants-rich spice model investigate effects on its antioxidant capacity (AOC). Sumac rendered PlantCrystals HPH. Particle size characterization proved presence submicron-sized particles (about 750 nm). Thus, able increased AOC bulk more than 650% according ORAC (oxygen radical absorbance capacity) assay. polyphenol flavonoid contents showed higher values after Interestingly, DPPH (1,1-diphenyl-2-picrylhydrazyl) assay also well (similar ascorbic acid) fact, PlantCrystal-technology demonstrated cause efficient cell rupture plant cells. This caused release resulted 6.5-fold when compared non-processed material.
