Assessment of novel algal biomass streams for their potential to enrich eggs with bioactive carotenoids - Phase II

虾青素(3，3‘-二羟基-β-胡萝卜素-4，4’-二酮)是一种由 微藻，包括血球菌属(即：雨生血球菌属)。这种类胡萝卜素 最近，它作为一种天然保健品的潜力受到了相当大的关注，特别是与其 抗氧化性能。工业合作伙伴迈埃拉集团公司已经为 生产富含虾青素的藻类生物量，其中类胡萝卜素水平，以及其他营养物质的含量 (包括长链脂肪酸)可以通过改变生长条件(光，温度， 二氧化碳含量)。虽然Myera Group Inc.的主要市场是天然保健品潜力 虾青素，有机会评估在家禽饲料中使用的副产品：1)用 虾青素，和2)作为一种新的饮食色素，以提高蛋黄的颜色。在我们最初的接洽资助期间， 我们建立了大量生产虾青素的条件，并建立了必要的生产 产生产蛋母鸡研究所需生物量的条件。在此Engage Plus奖励期间，我们将 确定包括富含虾青素的藻类生物质产品的效果，这些产品是在最初的 让Grant参与蛋鸡日粮对食用鸡蛋的营养状况和感官品质的影响。有了这个 目的：1)鸡蛋中总虾青素和长链omega-3脂肪酸随着 包括新的藻类生物质产品。此外，新成分的使用将提高蛋黄。 来自食用小麦饲料的母鸡的鸡蛋的颜色。一株来源于藻类的生物量的鉴定 富含虾青素的成分有可能：1)为加拿大消费者创造新产品 (富集蛋)；2)推进新的藻类生产系统，对社区发展产生影响，给出 Myera Group Inc.NSERC Funds的商业计划将产生关于可能的机制的新知识 将构成未来合作伙伴计划申请的基础(即：NSERC CRD)。

Astaxanthin (3,3'-dihydroxy-ß-carotene-4,4'-dione) is a carotenoid compound that can be produced by microalgae, including strains of Haematoccous (ie: Haemotococcus pluvialis). This carotenoid has garnered considerable attention of late for its potential as a natural health product, specifically related to its anti-oxidative properties. The industrial partner, Myera Group Inc., has developed a systems process for the production of astaxanthin-enriched algal biomass, where carotenoid levels, and the content of other nutrients (including long chain fatty acids) can be manipulated through changes in growth conditions (light, temperature, CO2 content). While a primary market for Myera Group Inc. is the natural health product potential of astaxanthin, opportunity exists to evaluate co-products for use in poultry feeds to: 1) enrich eggs with astaxanthin, and 2) serve as a novel dietary pigment to enhance yolk colour. During our initial Engage Grant, we established conditions for significant astaxanthin production and established the necessary production conditions to generate the required biomass for laying hen studies. During this Engage Plus grant, we will determine the effect of including the astaxanthin-enriched algal biomass products, derived during the original Engage Grant, into laying hen diets on the nutritional profile and sensory qualities of table eggs. With this objective, we expect to see that 1) egg total astaxathin and long chain omega-3 fatty acids increase with inclusion of novel algal biomass products. Furthermore, the use of the novel ingredients will enhance the yolk colour of eggs derived from hens consuming wheat-based diets. The identification of an algal biomass-derived ingredient enriched in astaxanthin has the potential to: 1) create new products for Canadian consumers (enriched eggs); 2) advance novel algae production systems with impacts for community development, given the business plan of Myera Group Inc. NSERC funds will yield new knowledge as to putative mechanisms that will form the basis of future partnership program applications (ie: NSERC CRD).
