Background

Oil extracted from shrimp processing by-products (SPBP) is rich in n-3 fatty acids and astaxanthin. These compounds are well known for health benefits, especially for the treatment of several chronic diseases. Conventional extraction method, in which organic solvents are generally used, results in low extraction yield of oil and poses serious environmental problems. Newly developed extraction methods aims at augmenting extraction efficiency and reducing the use of solvents.

Scope and approach

Shrimp oils extracted using various novel physical extraction processes have been discussed in terms of yield, quality and their uses. Stabilization of shrimp oil using different techniques has been addressed. Also a summary about potential medicinal and nutraceutical application of the shrimp oil has been revisited.

Key findings and conclusions: Shrimp oil containing polyunsaturated fatty acids and carotenoids, which exhibited higher health benefits than other fish oils, can be used as supplements. Physical processes used for extraction of oil from SPBP have a potential to improve the extraction process by eliminating excessive solvent usage and increasing the extraction yield. Modified or combined processes can subdue a few drawbacks faced during extraction of shrimp oil. Shrimp oil has excellent medicinal properties, however its use is limited in food or pharmaceutical industry. Therefore shrimp oil with stable form produced with scale-up processes at industrial level would be a value-added product for shrimp industry and marine resource sustainability can be achieved.

虾加工副产品中的油和颜料：提取，组成，生物活性及其应用-综述

背景

从虾加工副产物（SPBP）中提取的油富含n-3脂肪酸和虾青素。众所周知，这些化合物具有健康益处，尤其是用于治疗几种慢性疾病。通常使用有机溶剂的常规提取方法导致油的提取率低并且带来严重的环境问题。新开发的提取方法旨在提高提取效率并减少溶剂的使用。

范围和方法

关于产量，质量及其用途，已经讨论了使用各种新型物理提取方法提取的虾油。已经解决了使用不同技术稳定虾油的问题。还回顾了有关虾油潜在的医学和营养应用的摘要。

主要发现和结论：含有多不饱和脂肪酸和类胡萝卜素的虾油比其他鱼油具有更高的健康益处，可以用作补品。用于从SPBP中提取油的物理过程具有消除过多溶剂使用和提高提取产率的潜力，可改善提取过程。改进或组合的工艺可以消除虾油提取过程中面临的一些缺点。虾油具有出色的药用特性，但是在食品或制药行业中其使用受到限制。因此，在工业规模上通过规模化生产的稳定形式的虾油将成为虾产业的增值产品，并且可以实现海洋资源的可持续性。
