This research aimed to study the formation of edible oil-loaded beeswax microparticles using the Particles from Gas-Saturated Solutions (PGSS) process. Lipid binary mixtures (1:1 w/w) of beeswax with avocado oil or Brazil nut oil were studied as models. The PGSS process consisted of contacting the lipid binary mixture with supercritical CO₂ in an autoclave at pressures from 150 to 300 bar at a temperature of 60 °C with an agitation at 1250 rpm for 1 h and the subsequent expansion of the solution (lipids + CO₂) through a nozzle of 203.2 μm. The resulting edible oil-loaded beeswax microparticles had a sponge-like morphology and sizes of 162−180 μm and 96−128 μm when formulated with avocado oil and Brazil nut oil, respectively. Crystallinity and internal physical structure of the particles suggested uniform incorporation of edible oils into the crystalline lattice of beeswax. These particles could formulate ingredients for functional food products.

这项研究旨在研究使用气体饱和溶液中的颗粒（PGSS）工艺形成食用油的蜂蜡微粒的形成。研究了蜂蜡与鳄梨油或巴西坚果油的脂质二元混合物（1：1 w / w）作为模型。PGSS过程包括在60℃的温度下于150至300 bar的压力下，将脂质二元混合物与超临界CO ₂在高压釜中接触，并在1250 rpm的转速下搅拌1小时，随后溶液膨胀（脂质+一氧化碳₂）通过203.2μm的喷嘴。当用鳄梨油和巴西坚果油配制时，所得的食用油载蜂蜡微粒具有海绵状的形态，尺寸分别为162-180μm和96-128μm。颗粒的结晶度和内部物理结构表明食用油均匀掺入蜂蜡的晶格中。这些颗粒可以配制功能性食品的成分。
