不同干燥方式对芦笋功能成分及体外抗氧化活性的影响

中国果菜China Fruit &Vegetable第44卷,第1期2024年1月精深加工Deep Processing不同干燥方式对芦笋功能成分及体外抗氧化活性的影响马文华1,2,李苗苗1*,迟晓君1,于辉1,岳凤丽1(1.山东农业工程学院食品科学与工程学院,山东济南250100;2.河南工业大学粮油食品学院,河南郑州450001)摘要:为提高芦笋的耐贮性,本文探究了烫漂预处理和三种干燥方式(热风、冷冻和热风-微波干燥)对芦笋粉中总酚、VC 、多糖和黄酮等功能成分含量及其提取物体外抗氧化活性的影响。

结果表明,不烫漂冷冻干燥的芦笋粉色泽最好,且VC 含量最高。

热风-微波干燥的芦笋中总酚、多糖和黄酮的含量均最高,且烫漂的样品总酚、黄酮含量显著高于不烫漂样品,而多糖含量则是不烫漂的更高,其次为冷冻干燥。

干燥后芦笋醇提物的ABTS 自由基清除率为96%~97%,以冷冻干燥的样品最高,烫漂对其结果无显著影响;而其水提物含量以热风-微波干燥的样品最高,为96.25%,可见,烫漂提高了ABTS 自由基清除力。

水提物和醇提物的DPPH 清除率为烫漂后热风-微波干燥的芦笋粉最高。

综上,热风-微波干燥和烫漂有利于芦笋加工过程中总酚、多糖和黄酮的浸出以及抗氧化能力的保持,冷冻干燥有利于芦笋中VC 保留。

解决物理防晒喷雾3 大难题的良方

解决物理防晒喷雾3 大难题的良方

解决物理防晒喷雾3大难题的良方人们防晒不仅需要防止皮肤晒黑,还要阻止在紫外线的照射下皮肤产生晒伤和光老化问题。

紫外线几乎无处不在,因此,人们不仅要在炎热的夏季重视防晒,一年的四季同样都需要防晒。

资料提供|上海浦恩生物化学科技有限公司化妆品的纯物理防晒配方含有高含量的物理防晒剂,给防晒产品的配方开发带来了重重困难,喷雾剂型更加难以制备。

那么,究竟应该如何解决物理防晒喷雾剂型产品的这些制备难题呢?我们都知道,防晒产品剂型上大体可分为霜、乳、棒和喷雾等;以防晒剂性质区分,可分为化学防晒、物理防晒和生物防晒等。

我们今天就重点来介绍一下纯物理防晒剂的喷雾产品。

物理防晒的优点十分明显,它刺激性低更安全,且防晒效果持久,尤其适合敏感肌。

防晒喷雾更便于在夏季全身喷涂。

纯物理防晒配方含有高含量的物理防晒剂,给配方开发带来了挑战。

首先是如何更好地稳定悬浮这些物理防晒剂粉体;其次高含量粉体使得乳霜不具有较强的流动性,较难开发喷雾剂型产品;再次消费者更喜欢肤感清爽的产品,但纯物理防晒产品多为肤感厚重粘腻。

接下来笔者将介绍以下原料,看看它们是如何完美地解决物理防晒喷雾的这些制备难题的。

物理防晒喷雾剂型产品配方3大难题及解决方案如何解决物理防晒中高含量的粉体均匀分散和悬浮?如何帮助防晒产品形成细密喷雾?原料推荐:VIVAPUR CS TEX SUN INCI:微晶纤维素,纤维素胶原料推荐:VIVAPUR CS TEX SUN INCI:微晶纤维素,纤维素胶VIVAPUR CS TEX SUN是白色粉末状外观,使用前需要活化。

结构构成为:微晶纤维素被羧甲基纤维素钠包裹,羧甲基纤维素钠作为分散剂阻隔微晶纤维素之间的聚集。

其在用水分散搅拌和高剪切作用下被释放出来,这一过程也称为胶态微晶纤维素的活化过程,活化后的VIVAPUR CS TEX SUN形成的独特网状结构带来优异的悬浮和增稠性能。

VIVAPUR CS TEX SUN具有良好的触变性。

纳米纤维素制备稳态精油Pickering乳液

纳米纤维素制备稳态精油Pickering乳液

采用纳米纤维素制备稳态植物精油Pickering乳液的研究温春霞,梁浩*,袁其朋(北京化工大学生命科学与技术学院,北京,100029)通讯地址:北京市北三环东路北京化工大学制药工程系,邮编:100029联系方式:+86-10-6443-1557,传真:+86-10-6443-7610E-mail:******************摘要:采用过硫酸铵氧化玉米芯纤维素(CC)制备纳米纤维素晶体(CNCs),并用傅里叶红外光谱(FTIR),X射线衍射(XRD)和马尔文粒径分布仪对纳米纤维素进行表征,以及对其应用于植物精油Pickering乳液的制备和不同因素(温度,盐浓度,pH)对乳液稳定性影响进行了研究和考察。

结果表明制备的纳米纤维素晶体得率为53%,由此制备的Pickering乳液在温度从20℃升到70℃过程中,乳液的稳定性变大,当乳液处于高盐度的时候,由于纳米纤维素晶体负电荷之间的电荷屏蔽作用,致使乳液的稳定性提高。

由此说明纳米纤维素制备的植物精油Pickering乳液具有良好的稳定性。

关键词:纳米纤维素;Pickering乳液;制备;稳定性植物精油具有抗菌,抗氧化,抗癌活性,可用于日用化工,食品加工、化学助剂,农药,医药等行业[1]。

由于植物精油不溶于水而且易于被氧化降解,所以很难将其保存在富水相中或者固液界面中,因此选择一种有效而合适的方法来保护植物精油不被氧化是有待解决的问题。

近年来,作为解决这种问题的手段,乳化技术越来越受到广泛关注。

乳液是指一相液体以微小液滴状态分散于另一相液体中形成的非均相液体分散体系。

由油和水混合组成的乳浊液根据连续相和分散相不同,分成油包水型乳剂和水包油型乳剂,一般由表面活性剂或者表面活性物质来稳定体系[2]。

近年来,随着消费者观念转变和需求增高,比如,无毒,生物相容性和环境友好型,传统乳液受到越来越多的限制[3,4]。

Pickering乳液是由胶体尺寸的固体颗粒代替传统化学表面活性剂来稳定的液体,因其避免了表面活性剂的毒性和负面作(例如起泡、影响材料性能)以及独有的界面粒子自组装效应,近20年来受到了学者们的广泛关注[5,6]。

For drying processes, common NIR and GC systems measure only fi nal LOD (Loss on Drying), with little detail about internal processes.By contrast, AMETEK’s ProMaxion mass spectrometers give you not only all of the data you need to confi rm dryness at the endpoint, but also the data you need to understand the entire drying cycle, in detail, so you can improve its effi ciency and often shorten cycle times signifi cantly. The ProMaxion mass spectrometer lets you see solvent evaporation rate vs. dryer parameters essentially in real-time (delay = length of time required for the sample to traverse the distance from the dryer to the ProMaxion + instrument measurement time — typically one to two minutes, total).Not only are the data available almost immediately, they are so detailed you can even identify dryer paddle rotations. And that means ProMaxion data can help you to determine precisely when all potential drying work has been accomplished at each process step, which helps identify ineffective drying steps and excessive durations. The data can even help you recognize the presence of feedstock variations and anomalies and fl ag deviations from production procedures in previous production steps.Detailed Data — Simple OperationWhile the ProMaxion mass spectrometer provides unparalleled data detail and laboratory data quality, AMETEK’s DryerPoint™ software makes operation so easy and automatic that the analyzer can be set up and run by the plant’s production-line operators — no need for laboratory staff or specially trained instrument engineers. The DryerPoint software provides a simple, straightforward and intuitive user interface plus output that is easy to understand and use for process adjustment.Because of the richness of its data, the ProMaxion is also an ideal tool to use to begin feeding data into a six-sigma (6) model and to aid quality assurance greenbelts and blackbelts in making process quality assessments and improvements.Analytical F lexibility, S imple I nstallation and CalibrationThe ProMaxion mass spectrometer easily measures any combination of solvents, and you can change solvent analysis with each drying run. A multipoint, multipressure sample system with automatic purge allows one ProMaxion unit to accurately monitor up to seven dryers, even with different solvents in each dryer.Installation is also simple. One 6mm connection in the dryer vent header and a sample line run to the ProMaxion for each dryer is all that’s required — no further dryer modifi cations or dryer wall penetrations are needed.The ProMaxion unit can be air or watercooled, allowing operation at ambienttemperatures from 12°C to 40°C, it works with all dryer types, and it offers a variety of communications options including Ethernet (standard), RS232, RS485, fi beroptic, wireless radio, Modbus and OPC. Inlet pressures can range from 207 kPa to 3 mm Hg absolute.An onboard PC is optional, but the Windows ®-based DryerPoint software can also be run on a remote PC. The instrument operates on standard 115/230 VAC, 50/60 Hz current, at a maximum power consumption of 1000 W.The entire measuring and calibration process can be automated, and the ProMaxion output can be used to control all aspects of the drying cycle, without operator intervention.Self-diagnostics and modular design ensure easy maintenance by your own plant maintenance staff. Modem support is also available for additional factory diagnosis and troubleshooting — no need for staff maintenance specialists or an expensive maintenance contract.Some Typical ExamplesWhile the ProMaxion analyzer’s results on specifi c pharmaceutical customers’ production lines are generally protected by confi dentiality agreements, the unit has helped identify:1. A single-step process in which dryingwork stopped after less than half of the prescribed drying cycle.2. A multi-step process in which nodrying work was accomplished for an entire intermediate temperature cycle.3. A process that continued to run fornearly a full day after the ProMaxion showed all drying work had ceased and the product was dry. In each of these cases, the detailed process data allowed the company to adjust the drying process, with signifi cant energy savings and cycle-time reductions.To learn how a ProMaxion mass spectrometer might help you improve your drying operations, visit More Powerful Data Can Improve Dryer Effi ciency, Shorten Drying Cycles up to 50%Real-time, data-rich measurement of solvent drying processes can improve process effi ciency, ramp up process quality and satisfy PAT initiatives across a wide spectrum of drying operations.By Tony Slapikas, AMETEK Process & Analytical Instruments❚❘ ATEX T4 certifi ed ❚❘ ISO certifi ed❚❘ NEC C1, D1 compliant❚❘ FDA 21 CFR 11 compliant (software)❚❘IQ/OQ validation package available output to show in a typical single-step process.like in a typical three-step drying process.1097 mm420 mm496 mm1285 mmPurge Controller640 mm420 mm340 mm560 mmSample Port #7492 mmPurge GasInletI/O WiringI/O BoxRoughingPump Exhaust。
