Virgin Coconut oil (VCO) and serai wangi (Cymbopogon nardus) have been commonly used in medicines and cosmetics for health purposes as they contain important chemical compounds as well as increasing the taste of food. Chemical content can be obtained depending on the method used, one of which is the fermentation process using Saccharomyces cerevieae for amylase activity. This study aimed to measure mass spectrometry of compounds contained in virgin coconut oil and serai wangi before and after fermentation. The fermentation preparation method and the separation of compound contents were conducted using gas chromatography and ions fragments based on mass spectrometry. The results showed an increase in the amount of compound content after fermentation such as Citronella, Geraniol, and trans-Caryophyllene.Virgin Coconut oil (VCO) and serai wangi (Cymbopogon nardus) have been commonly used in medicines and cosmetics for health purposes as they contain important chemical compounds as well as increasing the taste of food.

Panax Ginseng has been utilized for its multiple effects such as preventing tumor, treating diabetes and cardiovascular disease and for antioxidant activities. These capabilities captured our interest to evaluate the encapsulation of different amount of ginseng (30 mg and 60 mg) within poly(lactic-co-glycolic acid) (PLGA) microcapsules by a double emulsion technique. The microcapsules were characterize by using attenuated total reflectance-Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results suggest that all microcapsules were successfully fabricated and the ginseng was successfully encapsulated in the PLGA microcapsules when the chemical functionality of ginseng (O–H and C=C bands) was found on both PLGA microcapsules contained 30 mg and 60 mg of ginseng. The morphology of microcapsules was in a spherical shape with smooth wall surfaces. The PLGA microcapsules with 30 mg ginseng has smaller size of microcapsules compared to the PLGA alone and more homogenous than the PLGA and PLGA microcapsules with 60 mg ginseng. The PLGA microcapsules with 60 mg ginseng were also found agglomerated in some area. As a conclusion, the amount of 30 mg ginseng within the PLGA microcapsules is seen practicable for the development ginseng encapsulated microcapsules for the application of drug delivery and coating materials.Panax Ginseng has been utilized for its multiple effects such as preventing tumor, treating diabetes and cardiovascular disease and for antioxidant activities.

人参具有多种作用,如预防肿瘤、治疗糖尿病和心血管疾病以及抗氧化活性。这些能力引起了我们的兴趣,通过双乳技术评估不同量的人参(30毫克和60毫克)在聚乳酸-羟基乙酸(PLGA)微胶囊中的胶囊化。采用衰减全反射-傅里叶变换红外光谱(FTIR)和扫描电镜(SEM)对微胶囊进行了表征。结果表明,当30 mg和60 mg人参的PLGA微胶囊上均存在人参的O-H和C=C带时,所有微胶囊均成功制备,人参被成功包裹在PLGA微胶囊中。微胶囊呈球形,壁面光滑。与含60 mg人参的PLGA微胶囊相比,含30 mg人参的PLGA微胶囊的微胶囊尺寸更小,且比含60 mg人参的PLGA和PLGA微胶囊更均匀。含60 mg人参的PLGA微胶囊在某些部位也出现了结块现象。综上所述,在PLGA微胶囊中加入30 mg人参是可行的,可用于开发人参微胶囊作为药物递送和包衣材料。人参具有多种作用,如预防肿瘤、治疗糖尿病和心血管疾病以及抗氧化活性。这些能力引起了我们的兴趣,通过双乳技术评估不同量的人参(30毫克和60毫克)在聚乳酸-羟基乙酸(PLGA)微胶囊中的胶囊化。采用衰减全反射-傅里叶变换红外光谱(FTIR)和扫描电镜(SEM)对微胶囊进行了表征。结果表明,当30 mg和60 mg人参的PLGA微胶囊上均存在人参的O-H和C=C带时,所有微胶囊均成功制备,人参被成功包裹在PLGA微胶囊中。微胶囊呈球形,壁面光滑。30 mg人参与PLGA微胶囊相比,其微胶囊尺寸更小,且更均匀。

Development of novel thin film composite reverse osmosis membranes for desalination 海水淡化用新型薄膜复合反渗透膜的研制
H. Qiblawey, H. Kumar, M. Nasser, A. Benamor, M. Al‐Ghouti
Microporous Polyetherimide (PEI) membranes were prepared by wet phase inversion at different temperatures. The thin film composites (TFC) of polyamide on microporous PEI were prepared using meta-Phenylenediamine (MPD) and 1,3,5-Benzenetricarbonyl chloride (BTC). The ATR FTIR characterization showed the formation of polyamide (PA) on microporous PEI membrane, whereas scanning electron microscopy (SEM) revealed that a thin film of polyamide is formed on microporous PEI. The cross-sectional SEM of PEI prepared at 60 °C, showed finger like morphology and sparingly distributed balloon like morphology for PEI synthesized at 80 °C. The performance of PEI membranes and PA TFCs were ascertained by studying permeation of water and rejection of sodium chloride by reverse osmosis. The polyamide TFC with hydrophobic PEI support structures exhibited permeation of 28 to 50 lm-2h-1, with 98 – 95 % 2000 ppm NaCl rejection at 60 bar pressure.

Biological degradation of biomass for the production of fine chemicals is getting much interest nowadays. However, the complex and recalcitrance structure of the biomass hinders the success story of the degradation. Lignin is the main composition that impedes the bioconversion of biomass. Hence, an optimize delignification pretreatment need to be developed to enable the biological degradation process becomes much easier and thus higher production yield can be achieved afterwards. This study focuses on the assessment of pineapple waste (PW) delignification by applying microwave radiation on two different pretreated PW to facilitate the processes. The PW was initially pretreated with distilled water (dH2O) and peracetic acid (PAA) prior to the microwave radiation. Three main parameters (pretreatment time, min; temperature, °C; and microwave radiation power, W) were studied towards the effect of PW delignification. Lignin percentage before and after the pretreatments were compared and analysed. The results obtained revealed that the microwave-assisted PAA shows the best percentage of delignification compared to the microwave-assisted dH2O pretreatment. The best delignification process obtained in this study is a key indicator for a better biomass degradation to achieve higher yield of products in the future.
生物降解生物质用于精细化工生产已成为人们关注的热点。然而,生物质的复杂和顽固性结构阻碍了降解的成功。木质素是阻碍生物质生物转化的主要成分。因此,需要开发一种优化的脱木质素预处理,使生物降解过程变得更加容易,从而达到更高的产率。本文研究了微波辐射对菠萝废弃物脱木质素的影响,通过微波辐射对两种不同预处理的菠萝废弃物脱木质素进行了评价。在微波辐射前,先用蒸馏水(dH2O)和过氧乙酸(PAA)对PW进行预处理。三个主要参数(预处理时间,min;温度、°C;微波辐射功率(W)对PW脱木质素的影响进行了研究。对预处理前后木质素含量进行了比较分析。结果表明,微波辅助PAA脱木质素率优于微波辅助dH2O预处理。本研究获得的最佳脱木质素工艺是未来更好的生物质降解以获得更高产品收率的关键指标。
