Thymol nanoemulsions formed via spontaneous emulsification: Physical and antimicrobial properties.

In this work, we prepared various sub-micron thymol emulsions with high hydrophilic-lipophilic balance (HLB) surfactants via spontaneous emulsification. Emulsion properties, such as size, polydispersity and charge, were assessed for each surfactant type and mass fraction. Emulsion stability was characterized by monitoring droplet size following exposure to physical (centrifugation) and thermal stressors (freeze, thaw cycling).

Quality and safety attributes of afghan raisins before and after processing.

Raisins are an important export commodity for Afghanistan; however, Afghan packers are unable to export to markets seeking high-quality products due to limited knowledge regarding their quality and safety. To evaluate this, Afghan raisin samples from pre-, semi-, and postprocessed raisins were obtained from a raisin packer in Kabul, Afghanistan. The raisins were analyzed and compared to U.
