Flaxseed: a potential source of food, feed and fiber 总被引:5,自引:0,他引:5
Singh KK Mridula D Rehal J Barnwal P 《Critical reviews in food science and nutrition》2011,51(3):210-222
Flaxseed is one of the most important oilseed crops for industrial as well as food, feed, and fiber purposes. Almost every part of the flaxseed plant is utilized commercially, either directly or after processing. The stem yields good quality fiber having high strength and durability. The seed provides oil rich in omega-3, digestible proteins, and lignans. In addition to being one of the richest sources of α-linolenic acid oil and lignans, flaxseed is an essential source of high quality protein and soluble fiber and has considerable potential as a source of phenolic compounds. Flaxseed is emerging as an important functional food ingredient because of its rich contents of α-linolenic acid (ALA), lignans, and fiber. Lignans appear to be anti-carcinogenic compounds. The omega-3s and lignan phytoestrogens of flaxseed are in focus for their benefits for a wide range of health conditions and may possess chemo-protective properties in animals and humans. This paper presents a review of literature on the nutritional composition of flaxseed, its health benefits, and disease-prevention qualities, utilization of flaxseed for food, feed, and fiber, and processing of flaxseed. 相似文献

ABSTRACT: Lignans are compounds found in a variety of plant materials including flaxseed, pumpkin seed, sesame seed, soybean, broccoli, and some berries. The major lignan in flaxseed is called secoisolariciresinol diglucoside (SDG). Once ingested, SDG is converted in the colon into active mammalian lignans, enterodiol, and entero‐lactone, which have shown promise in reducing growth of cancerous tumors, especially hormone‐sensitive ones such as those of the breast, endometrium, and prostate. Known for their hydrogen‐donating antioxidant activity as well as their ability to complex divalent transition metal cations, lignans are propitious to human health. The extraction methods vary from simple to complex depending on extraction, separation, fractionation, identification, and detection of the analytes. Flax lignan is also a source of useful biologically active components found in plant foods, such as phytochemicals, and it is considered a functional food. The safety issues in flaxseed are also briefly discussed. 相似文献

研究了脱毒亚麻饼粉的不同添加比例对馒头比容、色泽、质构、感官和营养等品质的影响。结果表明:添加过多的脱毒亚麻饼粉,会使馒头的比容、扩展比下降以及色泽变暗;质构结果表明,随着脱毒亚麻饼粉添加比例的增加,馒头的硬度、胶粘性与咀嚼性不断增加,弹性、内聚性与回复性不断减小;馒头的油脂、蛋白质和灰分含量逐渐增加,氨基酸含量除脯氨酸外均呈增加趋势,木酚素含量也显著增加(p0.05),添加15%脱毒亚麻饼粉馒头的木酚素含量高达3.34 mg/g;馒头的感官评分随着脱毒亚麻饼粉的添加比例增大逐渐降低,但添加3%和6%脱毒亚麻饼粉馒头的感官评分显著高于其他添加脱毒亚麻饼粉的馒头,二者的感官评分均大于90且没有显著性差异,因添加6%脱毒亚麻饼粉馒头含有更多的油脂、蛋白质和木酚素等营养物质,故选择脱毒亚麻饼粉的最佳添加比例为6%。 相似文献

以含50%开环异落叶松树脂酚二葡萄糖苷(SDG)的亚麻木酚素粗提物(50%SDG)为水解原料,对制备开环异落叶松树脂酚(SECO)粗提物的HCl浓度和水解时间进行优化,进一步通过溶剂萃取、真空冷冻干燥工艺制备SECO粗提物,并将其应用于磷脂-亚麻籽油乳液体系中,研究水解前后亚麻木酚素粗提物对磷脂-亚麻籽油乳液在65℃高温储藏过程中稳定性的影响。结果表明:在HCl浓度1 mol/L、水解时间120 min的条件下水解,可制备SECO含量为65%的SECO粗提物(65%SECO);在磷脂-亚麻籽油乳液高温储藏(65℃)过程中,65%SECO组乳液粒径无显著变化,但对照组和50%SDG组乳液粒径增大;与对照组乳液相比,储藏7 d,65%SECO和50%SDG可分别将乳液中氢过氧化物含量降低11%和27%。由此可见,在磷脂-亚麻籽油乳液的高温储藏(65℃)过程中,50%SDG具有较好的抑制油脂氧化的效果,但通过水解制备的65%SECO能显著提高磷脂-亚麻籽油乳液的物理稳定性。 相似文献

以未处理和焙炒处理后的亚麻籽为原料,采用溶剂浸提、液压压榨和螺旋压榨三种制油工艺,得到六种亚麻籽油和粕,探讨不同制取方法对亚麻籽油和亚麻籽粕品质的影响。结果表明:焙炒溶剂浸提法样品出油率最高(34.50%);在三种制油工艺中,焙炒处理后制得的亚麻籽油过氧化值和酸价均高于未处理组,但焙炒前处理可以提高亚麻籽油中总酚和维生素E含量;此外,制取工艺对亚麻籽油的氧化稳定性也有一定影响,其中螺旋压榨油氧化稳定性最好,且同种制取工艺间焙炒前处理可以增强亚麻籽油的氧化稳定性;制取工艺和焙炒前处理对亚麻籽油中亚麻酸含量和不饱和脂肪酸含量影响不显著,但焙炒处理组中的吡嗪、吡咯物质分别比未处理组高5.1%、15.8%、9.3%,未处理组中的醇类物质分别比焙炒处理组高6.1%、11.8%、3.7%。不同制取方法得到的亚麻籽粕中,未处理液压粕粗脂肪、粗蛋白和NSI(氮溶解系数)最高,焙炒螺旋压榨粕木脂素聚合物含量(16.70%)最高,且NSI也处于较高水平(33.13%);焙炒螺旋亚麻籽粕木脂素聚合物对DPPH、ABTS自由基清除率的半数清除率(IC50)分别为0.49 mg/mL和0.88 mg/mL。本研究结果对亚麻籽油的产业发展和亚麻籽加工副产物的利用提供了参考。 相似文献

Flaxseed is a major source of lignans, which are important bioactive compounds. The aims of this work were to validate a liquid chromatographic method for the rapid and simultaneous determination of the main lignans in flaxseed using high-performance liquid chromatography coupled with electrochemical detection and to analyze the composition of commercial samples of flaxseed. The performance criteria of the proposed method demonstrate that the method can be used for the analysis of secoisolariciresinol diglucoside (SDG), secoisolariciresinol (SECO), matairesinol (MATA), pinoresinol (PINO), lariciresinol (LARI), hydroxymatairesinol (HYDROXY), and isolariciresinol (ISOLARI) in flaxseeds at suitable levels. Calibration curves were determined for six different concentrations of standard solutions injected in triplicate. The sensitivity of the calibration curve was evaluated considering the confidence intervals of the intercept and slope. The limit of detection and limit of quantification were 7.4 and 10.9 μg/l, respectively, for LARI and 17.7 and 37.5 μg/l, respectively, for MATA. The relative standard deviation of repeatability values were lower than 2.59 %, which are acceptable because the Horwitz ratio values were 0.1 for all of the lignans. The recoveries of lignans were in the range of 74–100 % of SECO, which are consistent with the literature. The precision of the proposed method was determined by analyzing four flaxseed samples of different years and varieties. SDG was the main lignan present in all the samples, followed by ISOLARI and HYDROXY. 相似文献
