Carotenoids are lipophilic secondary plant compounds, and their consumption within fruits and vegetables has been positively correlated with a decreased risk of developing several chronic diseases. However, their bioavailability is often compromised due to incomplete release from the food matrix, poor solubility and potential degradation during digestion. In addition, carotenoids in food products are prone to oxidative degradation, not only lowering the nutritional value of the product but also triggering other quality deteriorative changes, such as formation of lipid pro-oxidants (free radicals), development of discolorations or off-flavor defects. Encapsulation refers to a physicochemical process, aiming to entrap an active substance in structurally engineered micro- or nano-systems, in order to develop an effective thermodynamical and physical barrier against deteriorative environmental conditions, such as water vapor, oxygen, light, enzymes or pH. In this context, encapsulation of carotenoids has shown to be a very effective strategy to improve their chemical stability under common processing conditions including storage. In addition, encapsulation may also enhance bioavailability (via influencing bioaccessibility and absorption) of lipophilic bioactives, via modulating their release kinetics from the carrier system, solubility and interfacial properties. In the present paper, it is aimed to present the state of the art of carotenoid microencapsulation in order to enhance storability and bioavailability alike.

关于微和纳米技术封装进展的全面概述,可增强类胡萝卜素的化学稳定性和生物利用度

类胡萝卜素是亲脂性的次生植物化合物,其在水果和蔬菜中的消费与罹患几种慢性疾病的风险降低呈正相关。然而,由于从食物基质中释放不完全,溶解性差以及在消化过程中可能降解,它们的生物利用度经常受到损害。此外,食品中的类胡萝卜素易于氧化降解,不仅降低了产品的营养价值,还引发了其他质量恶化的变化,例如脂质促氧化剂(自由基)的形成,变色或变味的发展。缺陷。封装是指一种物理化学过程,旨在将活性物质捕获在结构工程化的微系统或纳米系统中,为了开发有效的热力学和物理屏障,以应对恶化的环境条件,例如水蒸气,氧气,光,酶或pH值。在这种情况下,类胡萝卜素的包封已被证明是提高其在包括储存在内的常规加工条件下化学稳定性的非常有效的策略。此外,包封还可以通过调节亲脂性生物活性物质从载体系统的释放动力学,溶解度和界面性质来提高其生物利用度(通过影响生物可及性和吸收)。在本文中,目的是介绍类胡萝卜素微囊化的技术水平,以提高储存性和生物利用度。在这种情况下,类胡萝卜素的包封已被证明是提高其在包括储存在内的常规加工条件下化学稳定性的非常有效的策略。此外,包封还可以通过调节亲脂性生物活性物质从载体系统的释放动力学,溶解度和界面性质来提高其生物利用度(通过影响生物可及性和吸收)。在本文中,目的是介绍类胡萝卜素微囊化的技术水平,以提高储存性和生物利用度。在这种情况下,类胡萝卜素的包封已被证明是提高其在包括储存在内的常规加工条件下化学稳定性的非常有效的策略。此外,包封还可以通过调节亲脂性生物活性物质从载体系统的释放动力学,溶解度和界面性质来提高其生物利用度(通过影响生物可及性和吸收)。在本文中,目的是介绍类胡萝卜素微囊化的技术水平,以提高储存性和生物利用度。包封还可以通过调节其从载体系统的释放动力学,溶解度和界面特性来提高亲脂性生物活性物质的生物利用度(通过影响生物利用度和吸收)。在本文中,目的是介绍类胡萝卜素微囊化的技术水平,以提高储存性和生物利用度。包封还可以通过调节其从载体系统的释放动力学,溶解度和界面特性来提高亲脂性生物活性物质的生物利用度(通过影响生物利用度和吸收)。在本文中,目的是介绍类胡萝卜素微囊化的技术水平,以提高储存性和生物利用度。
