摘要:
To improve the water solubility, antioxidant activity, and chemical stability of curcumin, solid lipid nanoparticles (SLNs) were fabricated using equal masses of propylene glycol monopalmitate and glyceryl monostearate as the lipid matrix and sodium caseinate-lactose (NaCas-Lac) Maillard conjugate as the emulsifier. The entrapment efficiency was more than 90% when curcumin was 2.5% and 5.0% of lipid mass, and the SLNs were stable during 30-day storage. SLNs stabilized by NaCas-Lac showed better physicochemical properties than those prepared with NaCas, including higher sphericity and homogeneity; higher entrapment efficiency; better stability against pH, ionic strength, and simulated gastrointestinal digestions; and more controlled release. SLNs also greatly enhanced the antioxidant activity of encapsulated curcumin and the retention of curcumin during storage. Therefore, the present SLNs may find applications to deliver lipophilic compounds in functional foods and beverages. © 2020 American Chemical Society.

摘要:
通过对萝卜籽毛油样品前处理萃取方式的优化和加标回收实验,确定采用两步溶剂萃取方式检测萝卜籽油中莱菔素(sulforaphene,SFE)含量。考察萝卜籽预处理对SFE生成量的影响,以毛油中SFE含量为指标,分别用丙酮、二氯甲烷、乙醚、正己烷对其进行浸出法取油,并对比常规精炼与无水常温精炼工艺对油中SFE含量的影响。结果表明:用水和二氯甲烷进行两步萃取方式检测的萝卜籽毛油峰形好,响应值高,回收率和重复性较好。以SFE含量为指标,最佳的水分调节方式和预处理工艺是将萝卜籽进行粉碎后,直接喷洒调节水分质量分数到8%,25℃酶解10 min。最佳浸出溶剂为丙酮,浸出毛油中SFE含量高达832.36 mg/kg。采用常规精炼时,第1步水化脱胶后油中SFE就已完全损失。而采用无水常温精炼得到的萝卜籽油,SFE含量为760.35 mg/kg,保留率高达91.3%,同时,其基本指标均可达到国家三级食用油标准。本研究为萝卜籽油的加工和开发利用提供更多指导。

摘要:
The interfacial tension is one of the most important fundamental properties and presents crucial impacts throughout vegetable oil production, application and digestion. In this study, composition of vegetable oil including tocopherols, phytosterols, phenolic compounds, phospholipids, fatty acid composition and other constituents were determined. Furthermore, interfacial tension and its relationship with vegetable oil compositions were analyzed. Distribution and profile of composition of vegetable oil were remarkably different. The interfacial tension results showed physical refined vegetable oil exhibited an obviously lower interfacial tension than chemical refined oil attributed to abundant minor compositions. Moreover, the correlation analysis results indicated that phenolic compounds demonstrated the greatest influence on interfacial tension of vegetable oil against water with r = − 0.671, p = 0.009, followed by free fatty acid value, linoleic acid of triglyceride and phospholipids with r = − 0.639, 0.626, − 0.576 and p = 0.014, 0.017 and 0.031, respectively. No significant correlation was found between interfacial tension and other minor compositions. These results contribute to regulating lipid metabolism and evaluating oil quality more scientifically. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

摘要:
The present study focused on developing a rapid, efficient, and eco-friendly method for the analysis of perfluoroalkyl carboxylic acids (PFCAs) in aqueous matrices. The proposed method was based on esterification of PFCAs by isobutyl chloroformate followed by dispersive liquid–liquid microextraction (DLLME) of the derivatives. Quantitation of the isobutyl esters of PFCAs was carried out by gas chromatography-mass spectrometry with electron ionization. Under the optimal conditions, PFCAs could be determined in linear ranges of 1–1000 ngmL−1 with good correlation coefficients (r > 0.991). The limits of detection and limits of quantification ranged from 0.9 − 3.0 ngmL−1 and 2.7 − 9.0 ngmL−1, respectively. The method showed satisfactory reproducibility with intra-day and inter-day relative standard deviations (RSDs) in the range of 3.4 − 14.6% and 3.5 − 17.2%, respectively. It was successfully applied to determine PFCAs in several river and lake waters, ranging from 8.47 to 150.14 ngmL−1. © 2020, © 2020 Taylor & Francis Group, LLC.

摘要:
To increase the water solubility of zein as a stabilizing agent for oil-in-water (O/W) emulsions, three zein-polyglycerol (Zein-PG) conjugates, Zein-PG-2, Zein-PG-6, and Zein-PG-10, were prepared by dehydration between zein and polyglycerol aldehydes obtained by NaIO4 oxidation of polyglycerol-2, -6, and -10 and characterized by free amine content, grafting degree, Fourier transform infrared spectroscopy, and fluorescence spectra. All conjugates dispersed in water as nanoparticles were verified by transmission electron microscopy. Conjugation with PG changed the isoelectric point of zein from 6.2 to 6.8 and to 4.0. Zein-PG-6 and Zein-PG-10 showed strong stabilization on the O/W emulsions with 18-fold loading of soybean oil on the basis of conjugate mass, displaying high oil loading capacity. Confocal laser scanning microscopy (CLSM) confirmed the O/W structure of emulsions and that the absorption of Zein-PG-10 on the oil droplet surface offered the driving force to be stable. The present Zein-PG conjugates thus produced an enticing resource for use as nanocarriers or bioemulsifiers in food or pharmaceutical industries. ©

摘要:
将醋酸纤维素(CA)负载在活性炭(AC)表面制备成改性活性炭(MAC) 。采用扫描电镜、比表面及孔径分析仪、傅里叶变换红外光谱仪和元素分析仪对MAC的结构和形貌进行表征。重点探讨了吸附剂MAC中CA与AC质量比、吸附剂用量、吸附温度和吸附时间对MAC吸附食用油中邻苯二甲酸二丁酯(DBP)的影响,并且通过吸附动力学和热力学分析,研究MAC对食用油中DBP的吸附性能及机理。结果表明,MAC对食用油中DBP吸附的最佳条件为: CA与AC质量比0.025∶ 1,吸附剂用量为油质量的4%,吸附温度130℃,吸附时间50 min。在最佳条件下,MAC对DBP的吸附量为21.17 μg /g、吸附率达到40.48%,优于相同条件下AC的(15.10 μg /g、31.36%) 。吸附动力学和热力学分析表明,准二级动力学模型能更好地描述MAC的吸附过程,表明影响吸附过程的主要是吸附机理而非传质机理,Langmuir方程能更准确地描述其吸附过程。

摘要:
To develop solid lipid nanoparticles (SLNs) with a new lipid matrix for delivery of hydrophobic bioactive molecules, high purity 1-laurin-3-palmitin (1,3-LP) was synthesized and the prepared 1,3-LP SLNs were compared with those of two common SLN matrices in glyceryl monostearate (GMS) and glyceryl tripalmitate (PPP). Conditions of preparing SLNs were first optimized by evaluating the particle size, polydispersity index (PDI), zeta-potential, and stability. Thereafter, the performance of SLN loading of a model compound in thymol was studied. The loading capacity of thymol in 1,3-LP SLNs was 16% of lipids and higher than 4% and 12% for GMS- and PPP-SLNs, respectively. The 1,3-LP SLNs also had the best efficiency to entrapment thymol during the prolonged storage. X-ray diffraction (XRD) analyses confirmed the excellent crystalline stability of 1,3-LP leading to the stable entrapment efficiency and better stability of thymol-loaded SLNs. Conversely, the polymorphic transformation of GMS and PPP resulted in the declined entrapment efficiency of thymol in the corresponding SLNs. This work indicated the 1,3-diacylglycerol (DAG) SLNs could be used as a promising delivery system for the encapsulation of hydrophobic bioactive molecules with high loading capacity and stability. © 2019 by the authors.

摘要:
目的:开发具有稳定脂质基质结构的固体脂质纳米粒(solid lipid nanoparticles,SLNs)以更好地递送生物活性物质。方法:以丙二醇单棕榈酸酯(propylene glycol monopalmitate,PGMP)和单硬脂酸甘油酯(glyceryl monostearate,GMS)为复合脂质、香芹酚为药物模型,制备了香芹酚SLNs,考察了PGMP和GMS的复配比例对SLNs的物理化学稳定性、载药量和包封率的的影响,并对其透射电镜形貌、荧光光谱和释放动力学进行了表征,同时研究了香芹酚SLNs对大肠杆菌0157:H7和金黄色葡萄球菌的抑菌活性。结果:当PGMP与GMS质量比为2:1和1:1时能够制备稳定的SLNs,香芹酚载药量可高达脂质的30%,包封率在98%以上。电镜观察、荧光光谱和药物释放曲线表明香芹酚成功地被包封并且均匀地分布在脂质纳米粒中。用相同质量的PGMP和GMS制备的香芹酚SLNs具有更高的储存稳定性,并且比游离香芹酚表现出更强的抑菌效用,香芹酚与脂质基质表现出协同抑菌活性。结论:新型脂质基质的固体脂质纳米粒递送体系具有更优异的物理化学性质,在食品和其他领域中具有潜在应用。

摘要:
To develop solid lipid nanoparticles (SLNs) with stable lipid matrix structures for the delivery of bioactive compounds, a new class of SLNs was studied using propylene glycol monopalmitate (PGMP) and glyceryl monostearate (GMS) mixtures and carvacrol as a model lipophilic antimicrobial. Stable SLNs were fabricated at PGMP:GMS mass ratios of 2:1 and 1:1, and the carvacrol loading was up to 30% of lipids with >98% encapsulation efficiency and absence of visual instability. Fluorescence spectra and release profiles indicated the carvacrol was successfully encapsulated and homogeneously distributed within the SLNs. SLNs fabricated with equal masses of PGMP and GMS had better stability of carvacrol during storage and higher sphericity than those with a ratio of 2:1 and were much more effective than free carvacrol against Escherichia coli O157:H7 and Staphylococcus aureus. These findings demonstrated the potential applications of the studied SLNs in delivering lipophilic bioactive compounds in food and other products. © 2019 by the authors.

摘要:
研究了磷化氢敏感和抗性赤拟谷盗信息素的种类和相对含量,表明两者存在差异。两者的GC-MS检测结果均表明可能含有目前已报道的4,8-二甲基癸醛和1-十五烯两种聚集信息素;磷化氢抗性赤拟谷盗信息素种类比敏感赤拟谷盗多1-十六烯、1,3-二异丙基萘和2,4-二异丙基萘这三种信息素,缺少反式十氢化萘和(Z)-7-十六碳烯醛这两种信息素。对比4,8-二甲基癸醛相对含量,磷化氢敏感赤拟谷盗比抗性赤拟谷盗的4,8-二甲基癸醛高2倍。

摘要:
采用0.9%(w/w)稀硫酸分别在80℃和90℃下浸泡处理脱脂米糠2 h后再经超声波处理,米糠蛋白提取率从53.1%分别提高至61.9%和72.8%,在此基础上进一步研究了稀酸-超声波协同处理对米糠蛋白功能特性与结构的影响。与原样米糠蛋白相比,两种稀酸-超声波处理所得米糠蛋白的乳化活性均无显著改善,乳化稳定性均有所降低;两种米糠蛋白的起泡能力则均显著改善(P <0.05),其中80℃浸泡条件下所得米糠蛋白的泡沫稳定性略有改善。对米糠蛋白结构进行分析后发现,经稀酸-超声波处理后米糠蛋白形成了相对大分子量的蛋白质聚集体,导致米糠蛋白的表面疏水性降低;圆二色谱实验结果表明,处理后米糠蛋白的α-螺旋和β-折叠结构的含量相对减少而β-转角和无规卷曲含量则增加;荧光光谱分析则发现最大荧光发射波长发生了红移且荧光强度降低。上述分析结果表明协同处理使得米糠蛋白的分子结构展开,分子柔性增加,从而有利于米糠蛋白的溶解和起泡能力的提高,但由于分子间的聚集也使得其乳化稳定性降低。

摘要:
考察pH值和NaCl浓度对米糠蛋白起泡特性及泡沫微观形态的影响,并对二者之间的内在关系进行阐述.结果表明,当米糠蛋白溶液中不添加NaCl、pH 4时起泡能力较差,但泡沫稳定性可达最大值(88.3±7.3)%,而当溶液的pH值偏离4时起泡能力增加,在pH 10和12条件下起泡能力分别可达(73.3±0)%和(168.9±10.2)%,泡沫稳定性分别为(74.7±2.5)%和(68.5±2.1)%;另外在米糠蛋白溶液pH值为4和7条件下分别添加1%的NaCl后,可显著提高起泡能力至(77.8±3.8)%和(90.0±5.8)%.米糠蛋白泡沫的微观形态随时间变化规律说明,不同pH值条件下起始阶段气泡的直径大小分布与泡沫稳定性相关,而当添加NaCl后米糠蛋白起泡能力和泡沫稳定性的改变则与气泡数量和平均面积二者的综合效应有关.
