GPPS产品再加工颜色变黄的原因分析

通过多次挤出透明聚苯乙烯(GPPS),模拟产品再加工,分析了多次挤出对GPPS黄色指数、熔体流动速率、相对分子质量、透光率、残留单体以及低聚物含量等的影响。GPPS残留单体含量,低聚物含量以及在后加工过程中受到高温、高剪切作用时的降解程度和被氧化程度是致使GPPS产品回收利用过程中颜色变黄的主要原因。建议在生产过程中加入少量酚类抗氧剂以改善GPPS产品再加工时颜色变黄的现象。

Volume and Sensory Properties of Yellow Cakes as Affected by High Fructose Corn Syrup and Corn Oil

The effects of high fructose corn syrup (HFCS) and corn oil (CO) on volume and deformation and effects of mono- and diglyceride (MDG) and sucrose ester (SE) emulsifiers on volume and sensory properties of yellow cakes were studied. 50% HFCS gave the greatest volume; 100% HFCS decreased volume; CO increased volume. Deformation was greatest in 50% HFCS cakes with 50% or 100% CO. Simultaneous optimization of volume and deformation was predicted at 35% HFCS and 67% CO levels. HFCS affected tenderness and aftertaste but not sweetness in cakes formulated with 100% CO. SE emulsified cakes were sweeter than unemulsified or MDG emulsified 100% CO cakes when formulated with 50% and 100% HFCS.     

蒸汽汽蒸技术脱除聚丙烯中挥发性有机物

在聚丙烯颗粒料脱除挥发性有机物（VOCs）中试实验装置中,以蒸汽为脱附介质,采用蒸汽汽蒸技术脱除降解法中、高熔体流动速率高抗冲聚丙烯（二者牌号分别为1215 C,630）中的VOCs。结果表明:于脱挥塔中,在脱挥温度为120 ℃,停留时间为2.5 h的最佳条件下,可将1215 C,630中含VOCs量由脱挥前的432.0,514.0 μg/g分别降至脱挥后的39.9,47.0 μg/g;在不同脱挥条件下,2种产品脱挥前后力学性能均相近;与脱挥前相比,脱挥后1215 C黄色指数略有提高,但是仍处于合格范围内。

The clinical and immunomodulatory effects of green soybean extracts

The present study was performed to investigate the immune-modulating activities of extracts from green soybean (Glycine max) in a 2,4-toluene diisocyanate (TDI)-inducing guinea pig rhinitis model and a human trial study for allergic rhinitis. Hot water extracts of green soybean were chosen for animal experimentation on the basis of their ability to regulate the production of B cell-activating factor of the TNF family and a proliferation-inducing ligand in mouse spleen cells. Green soybean extracts significantly decreased the levels of ovalubumin (OVA)-specific IgE in mice and significantly suppressed the TDI-induced nasal mucosa secretion. An open-label human pilot study was performed on 16 subjects, using Japanese cedar pollinosis. The symptom scores for Japanese cedar pollinosis were better in the long-term green soybean extracts intake group than in the withdrawal short-term intake group. Green soybean extracts had great potential as an orally active immune modulator for the treatment of various allergic diseases.
