为提高刺梨果渣利用率,减少资源浪费和环境污染。本研究以刺梨果渣为原料,采用固态发酵改性刺梨果渣膳食纤维(dietary fiber,DF),以可溶性膳食纤维(soluble dietary fiber,SDF)与不溶性膳食纤维(insoluble dietary fiber,IDF)比值(SDF/IDF)为响应值,接种量、发酵温度和发酵时间为考察因素,利用响应面试验优化刺梨果渣最佳发酵工艺,并分析发酵前和发酵后膳食纤维结构特性与理化性质。结果表明,刺梨果渣最佳发酵工艺为:发酵时间为4 d,温度为40℃,接菌量为7.5%, SDF/IDF为14.21%±0.42%;理化性质分析表明,发酵后较发酵前持水力、持油力及膨胀力增大;超微结构分析发现,发酵后DF呈现片层状,表面粗糙,结构疏松;红外图谱分析表明,发酵后DF吸收峰强度增大,整体峰型及位置未发生改变,X-射线衍射图谱表明发酵后衍射峰强度减弱,结晶结构未发生变化。刺梨果渣经枯草芽孢杆菌发酵可改变DF结构,并改善其理化特性。

Plasma-enhanced transdermal drug delivery(TDD) presents advantages over traditional methods,including painless application, minimal skin damage, and rapid recovery of permeability. To harness its clinical potential, factors related to plasma’s unique properties, such as reactive species and electric fields, must be carefully *** review provides a concise summary of conventional TDD methods and subsequently offers a comprehensive examination of the current state-of-the-art in plasma-enhanced TDD. This includes an analysis of the impact of plasma on HaCaT human keratinocyte cells, ex vivo/in vivo studies, and clinical research on plasma-assisted TDD. Moreover, the review explores the effects of plasma on skin physical characteristics such as microhole formation, transepidermal water loss(TEWL), molecular structure of the stratum corneum(SC), and skin resistance. Additionally, it discusses the involvement of various reactive agents in plasma-enhanced TDD, encompassing electric fields,charged particles, UV/VUV radiation, heat, and reactive species. Lastly, the review briefly addresses the temporal behavior of the skin after plasma treatment, safety considerations, and potential risks associated with plasma-enhanced TDD.
