An investigation on fatty acid, triacylglycerol, tocopherol, and xanthophyll contents and thermal properties of pecan (Carya illinoinensis) kernel oils from two cultivars was carried out. The main fatty acids were oleic acid, followed by linoleic and palmitic acids. The predominant triacylglycerols were OOL, OOO, and OLL (where O stands for oleoyl and L for linoleoyl). Pecan kernel oil is a rich source of tocopherols, mainly γ-tocopherol. Two xanthophylls (lutein and zeaxanthin) were investigated, and lutein was found to be the major one. Thermal behavior was studied by differential scanning calorimetry (DSC). Pecan nut oil displayed melting and crystallization transitions at low-temperature zones. The difference between DSC parameter values provides a path for distinguishing among cultivars. These data promote pecan kernel oil as a potential source of bioactive compounds with nutraceutical properties (monounsaturated fatty acids, tocopherols, and xanthophylls) and reveal, for the first time, the thermal properties of Carya illinoinensis oil.
对两个品种山核桃仁油的脂肪酸、甘油三酯、生育酚和叶黄素含量及热性能进行了研究。主要脂肪酸为油酸,其次为亚油酸和棕榈酸。主要的三酰基甘油是OOL、OOO和OLL(其中O代表油基,L代表亚油基)。山核桃仁油含有丰富的生育酚,主要是γ-生育酚。研究了两种叶黄素(叶黄素和玉米黄素),发现叶黄素是主要的叶黄素。用差示扫描量热法(DSC)研究了其热行为。山核桃油在低温区呈现熔融结晶转变。DSC参数值的差异为品种间的区分提供了途径。这些数据促进了山核桃仁油作为具有营养保健性质(单不饱和脂肪酸、生育酚和叶黄素)的生物活性化合物的潜在来源,并首次揭示了山核桃油的热特性。

The cooling of olives stored in containers with a capacity of 400 kg risk accumulation of respiration heat and subsequent fruit deterioration. Pre-cooling the fruit to 5 °C before cold storage was studied as a possible solution to overcome this obstacle. The fruit temperature within the containers was recorded daily for 14 days and oil was extracted at days 0, 4, 8, and 14. A second experiment evaluated a rapid pre-cooling procedure at -18 °C for 3 min. No significant alterations at the level of the examined parameters were recorded. The internal temperature of the control container declined and stabilized at around 12 °C. The temperature of the pre-cooled fruit increased to up to 8 °C. The examined parameters showed no significant alterations in either experiment and the rapid pre-cooling treatment did not lead to any visible ‘chill injuries’. A pre-cooling treatment at 5 °C was successfully introduced at the farm of a small producer.

The total phenol content (TPC) in coconut oil varies with extraction method, variety, nature of coconut kernel components and geographical origin. Commonly reported TPCs of coconut oils extracted by dry methods and wet methods are in the range of 70-300 mg/kg and 250-650 mg/kg, respectively. Based on the commonly reported data, the TPC of coconut oil varies by up to 527 mg/kg oil, 180 mg/kg oil, and 172 mg/kg oil due to the influence of the extraction method, coconut variety and the nature of kernel components, respectively. The identity of the phenolic compounds also varies with the extraction method. Caffeic acid, catechin, p-coumaric acid, ferulic acid, and syringic acid are present in different quantities in coconut oil when extracted by all methods. However, chlorogenic acid, cinnamic acid, epigallocatechin, gallic acid, vanillic and epicatechin are present only in some coconut oils. Many free phenolic compounds present in olive oil are also present in coconut oil.
椰子油中总酚含量(TPC)因提取方法、品种、椰子仁成分性质和产地而异。通常报道的干法和湿法提取椰子油的TPCs分别在70-300 mg/kg和250-650 mg/kg之间。根据通常报道的数据,由于提取方法、椰子品种和籽粒成分性质的影响,椰子油的TPC分别变化高达527 mg/kg油、180 mg/kg油和172 mg/kg油。酚类化合物的性质也随提取方法的不同而不同。咖啡酸、儿茶素、对香豆酸、阿魏酸和丁香酸在用各种方法提取的椰子油中都有不同数量的存在。然而,绿原酸、肉桂酸、表没食子儿茶素、没食子酸、香草酸和表儿茶素只存在于某些椰子油中。橄榄油中存在的许多游离酚类化合物也存在于椰子油中。

The total phenols in virgin olive oil are highly dependent on cultivar, but also on ripening stage and other agronomic factors. The focus of most studies on agronomic factors has been irrigation, while fertilization has received less attention. Most of the fertilization works find that nitrogen over-fertilization leads to a decrease in phenol contents in virgin olive oil (VOO) and extra virgin olive oil (EVOO), under rain-fed or irrigation management. Ortho-diphenols also decrease with high doses of nitrogen, with no effect on secoiridoids. Phosphorous has a minor effect on irrigated trees; while the role of potassium is controversial, with a lack of trials with calcium and micro-nutrients. Due to the great impact of the fertilization on the phenol content and quality of VOO, new research is necessary with focus aimed at different cultivars and agronomic factors.
初榨橄榄油中总酚类物质的含量与品种高度相关,也与成熟期等农艺因素有关。大多数关于农艺因素的研究都集中在灌溉方面,而对施肥的关注较少。大多数施肥工作发现,在雨水灌溉或灌溉管理下,过量施肥会导致初榨橄榄油(VOO)和特级初榨橄榄橄榄油(EVOO)中苯酚含量下降。邻二酚也会随着高剂量的氮而减少,而对secoiridoids没有影响。磷对灌溉树木的影响很小;而钾的作用存在争议,缺乏对钙和微量营养素的试验。由于施肥对VOO的酚含量和质量有很大影响,因此有必要针对不同的品种和农艺因素进行新的研究。

Potato cookies were formulated by replacing red palm stearin (RPS) by red palm olein (RPOL) at 0, 17 and 35%, and then baked at 160, 180 and 200 °C for 10, 12 and 15 min. The sensory analysis, using an orthogonal test, showed that a RPS-RPOL ratio of 65:35, baking temperature of 160 ºC, and baking time 12 min were the optimal conditions. Cookies made from 65% RPS + 35% RPOL composition exhibited 0.6 times less squalene, but 1.5 times more β-carotene, tocopherols and tocotrienols than the mixture of RPS and RPOL at 100:0. In addition, cookies with superior oxidative stability were obtained at a lower temperature (160 ºC) and short baking time (10 min). This study demonstrates that the application of RPOL and RPS blending can positively enhance the nutritional properties and oxidative stability of baked food, and that using potato in the baking processing may be beneficial.
以0、17和35%的红棕榈油蛋白(RPOL)代替红棕榈硬脂酸(RPS),然后在160、180和200°C下烘烤10、12和15分钟,制成土豆饼干。采用正交试验进行感官分析,结果表明,RPS-RPL比例为65:35,烘烤温度为160ºC,烘烤时间为12分钟是最佳条件。在100:0时,由65%RPS+35%RPOL组成的饼干显示出角鲨烯减少0.6倍,但β-胡萝卜素、生育酚和生育三烯醇增加1.5倍。此外,在较低的温度(160ºC)和较短的烘焙时间(10分钟)下获得了具有优异氧化稳定性的饼干。本研究表明,RPOL和RPS共混的应用可以积极提高烘焙食品的营养特性和氧化稳定性,在烘焙加工中使用土豆可能是有益的。

Mineral-based lubricants are being supplanted by bio-based lubricants because of environmental concerns and the depletion of fossil resources. The derivatives of edible and non-edible oils are considered potential alternatives to existing natural mineral oil base stocks in certain lubricant applications, where immediate intraction with the environment is predicted. A new class of epoxides were synthesized from the undecylenic esters of 2-ethyl hexanol, neopentyl glycol (NPG), and trimethylolpropane (TMP). These unsaturated esters were epoxidized by using meta chloro perbenzoic acid. The synthesized epoxides were characterized by spectral studies (1HNMR, 13CNMR, IR) physio-chemical (density, specific gravity) and lubricant properties (kinematic viscosity, viscosity index, flash point, fire point, cloud point, pour point, copper strip corrosion). TMP epoxide has a high viscosity index, high flash point, and low pour point compared to 2-ethyl hexyl epoxide and NPG epoxide.
由于环境问题和化石资源的枯竭,矿物基润滑剂正在被生物基润滑剂所取代。食用油和非食用油的衍生物被认为是在某些润滑剂应用中现有天然矿物油基础油的潜在替代品,在这些应用中,预计会与环境直接相互作用。以2-乙基己醇十一烯酯、新戊二醇(NPG)和三甲基丙烷(TMP)为原料合成了一类新的环氧化合物。用邻氯过苯甲酸对这些不饱和酯进行了环氧化。通过光谱(1HNMR、13CNMR、IR)、理化(密度、比重)和润滑性能(运动粘度、粘度指数、闪点、燃点、浊点、倾点、铜带腐蚀)对合成的环氧化物进行表征。与2-乙基己基环氧化物和NPG环氧化物相比,TMP环氧化物具有高粘度指数、高闪点和低倾点的特点。

The aim of this study was to investigate the removal of 3-monochloropropane-1,2-diol (3-MCPD) and glycidyl esters (GEs) from edible oils by using Metal Organic Frameworks (MOF) and natural clays. First, the model oil was treated with adsorbents and titanium (IV) butoxide-terephthalate MOF (Ti-MOF) and kaolin were selected as the best performing MOF along with natural clay, respectively, for the removal of 3-MCPD and GEs. The effects of treatment conditions were also investigated, 6.0% adsorbent level, 120 min treatment time and 95 ºC temperature were determined to be the best treatment parameters. Finally, palm oil samples were treated with Ti-MOF and kaolin under the selected conditions and removal of 3-MCPD and GEs was obtained at up to 27% and 58%, respectively. In conclusion, MOFs and natural clays showed good potential for the removal of 3-MCPD and GEs, and the efficiency of the treatment can be improved by modifying the adsorbents.

Recent advances in plant-based fat formulation as substitute for lard 植物性脂肪替代猪油的研究进展

Lard is one of the main animal fats used as shortening and frying medium. Religious prohibitions and negative health perceptions regarding animal fats have caused concerns about the consumption of lard among communities living around the world. Various research efforts have been made in the past to formulate plant-based fats and shortenings as substitutes for the exclusion of lard from food. This would eventually help countries to regularize food formulations according to their religious compliance. As the existence of a single plant fat as substitute for lard has not been discovered from nature, researchers attempted to study the possibility of mixing native fats and oils such as enkabang fat, canola oil, guava oil, palm oil, palm stearin, soybean oil and cocoa butter as raw materials. The compatibility of the formulated plant-based fat substitute for lard was assessed in terms of chemical composition and thermo-physical properties. The formulated plant-based shortenings and lard shortening were simply plastic fats based on their consistency value and existence of β’ and β-form polymorphs of which the β’ -form was dominant. The functional properties of formulated plant-based shortenings and lard were also compared in the formulation of cookies. Although a substantial amount of work has been done over the past decade, there was hardly any discussion on the pros and cons of the approaches used for raw material selection and the criteria adopted in the assessment of the formulated products. Hence, this review intended to bring an update of the progress of studies with regard to these two aspects.
猪油是用作起酥油和油炸介质的主要动物脂肪之一。宗教禁令和对动物脂肪的负面健康观念引起了世界各地社区对猪油消费的担忧。过去,人们进行了各种研究,以配制植物性脂肪和酥油,作为将猪油排除在食物之外的替代品。这最终将有助于各国根据其宗教信仰规范食品配方。由于尚未从自然界中发现单一植物脂肪可以替代猪油,研究人员试图研究将天然脂肪和油(如恩卡邦脂肪、菜籽油、番石榴油、棕榈油、棕榈硬脂、大豆油和可可脂)混合作为原料的可能性。从化学成分和热物理性能方面评估了配方植物性脂肪替代猪油的相容性。配方植物性缩短剂和猪油缩短剂是简单的塑性脂肪,因为它们的稠度值以及β'和β-型多晶型的存在,其中β'型占主导地位。在饼干的配方中,还比较了配方植物性酥油和猪油的功能特性。尽管在过去十年中做了大量工作,但几乎没有讨论过原材料选择方法的利弊以及配方产品评估中采用的标准。因此,本次审查旨在更新这两个方面的研究进展。

Religious prohibitions and negative health perceptions regarding animal fats have caused concerns about the consumption of lard among communities living around the world. Various research efforts have been made in the past to formulate plant-based fats and shortenings as substitutes for the exclusion of lard from food. This would eventually help countries to regularize food formulations according to their religious compliance. As the existence of a single plant fat as substitute for lard has not been discovered from nature, researchers attempted to study the possibility of mixing native fats and oils such as enkabang fat, canola oil, guava oil, palm oil, palm stearin, soybean oil and cocoa butter as raw materials. The compatibility of the formulated plant-based fat substitute for lard was assessed in terms of chemical composition and thermo-physical properties. The formulated plant-based shortenings and lard shortening were simply plastic fats based on their consistency value and existence of β’ and β-form polymorphs of which the β’ -form was dominant. The functional properties of formulated plant-based shortenings and lard were also compared in the formulation of cookies. Although a substantial amount of work has been done over the past decade, there was hardly any discussion on the pros and cons of the approaches used for raw material selection and the criteria adopted in the assessment of the formulated products.

The optimal process conditions of the advanced aqueous method for recovering oil and de-oiled meal from pumpkin seed kernels were: baking the kernels at 110 °C for 1 min, grinding them to pass through a sieve of 150 μm pore size, adding 1.60 ml brine to 10.00 g ground kernels, stirring for 30 min at 30 °C, centrifuging at 4000 r/min for 30 min and cold-pressing the residue from centrifugation. This method recovered > 94% oil. Its oil recovery rate was comparable to that of solvent extraction and higher than that of enzyme-assisted aqueous method or hot-pressing. It recovered edible oil with higher quality and level of coenzyme Q10, tocopherols, carotenoids, total phytosterols and squalene as compared to solvent extraction or hot-pressing and requirements of China’s national standard. It is superior to enzyme-assisted aqueous method or hot-pressing for recovering de-oiled meal which is suitable for making texturized protein.
先进水法回收南瓜籽油和去油粕的最佳工艺条件为:将南瓜籽在110℃下烘烤1 min,研磨后通过孔径为150 μm的筛孔,10.00 g磨碎的南瓜籽中加入1.60 ml盐水,在30℃下搅拌30 min,在4000 r/min的转速下离心30 min,对离心后的残渣进行冷压处理。该方法的采收率为140.94%。其油回收率与溶剂萃取法相当,高于酶助水法或热压法。与溶剂萃取或热压法相比,回收的食用油中辅酶Q10、生育酚、类胡萝卜素、植物甾醇和角鲨烯的质量和含量更高,符合中国国家标准的要求。该方法优于酶助水法或热压法回收脱油粕,适用于制作结构化蛋白。

This study investigated baru oil and partially defatted baru flour from the northwest region of Minas Gerais, Brazil. The physicochemical characterization of the oil was made by determining the fatty acid profile using gas chromatography, lutein, and α- and β- carotenes by means of high-performance liquid chromatography, and total carotenoids by spectrophotometry. The flour was analyzed for its chemical composition, fiber, and mineral contents. Baru oil presented excellent quality parameters and high contents in unsaturated fatty acids and carotenoids. The flour showed relevant levels of proteins, lipids, and dietary fiber, in addition to having representative mineral contents for food such as manganese, magnesium, and copper. Thus, baru oil and the by-product of its extraction offer a rich chemical composition, and their application may add nutritional value to foods in addition to reducing negative environmental impacts.
本研究调查了巴西米纳斯吉拉斯西北地区的巴鲁油和部分脱脂巴鲁面粉。通过气相色谱法测定脂肪酸图谱,通过高效液相色谱法检测叶黄素、α-和β-胡萝卜素,通过分光光度法测定总类胡萝卜素,对油的理化性质进行了表征。对面粉的化学成分、纤维和矿物质含量进行了分析。巴鲁油具有优良的品质参数和高含量的不饱和脂肪酸和类胡萝卜素。除了具有代表性的锰、镁和铜等食物矿物质含量外,面粉还显示出相关的蛋白质、脂质和膳食纤维水平。因此,巴鲁油及其提取的副产品具有丰富的化学成分,它们的应用除了可以减少对环境的负面影响外,还可以增加食品的营养价值。
