富含虾青素的食物

虾青素是一种酮类胡萝卜素,化学名称为 3,3′-二羟基-4,4′-二酮-
β,β’-胡萝卜素。为红色固体粉末,脂溶性,不溶于水,但溶于大多数有机溶剂。虾青素在自然界中广泛存在,尤其是在虾、蟹、鱼和鸟类等水生动物中,是这些生物出现红色或粉红色的主要原因。

什么是虾青素

虾青素以其非常有效的抗氧化特性而闻名,其功效超过维生素 E、维生素 C 和其他传统抗氧化剂。作为一种断链抗氧化剂,虾青素可有效中和自由基(包括二氧化氮和各种硫化物),同时减轻脂质过氧化,保护细胞免受氧化损伤。研究表明,虾青素具有许多生理益处:抑制肿瘤发生、增强免疫功能、防止紫外线引起的皮肤损伤、促进眼部健康和对抗衰老过程。

虾青素的主要天然来源是雨生红豆;这种微藻可含有高达 6% 的虾青素含量,使其成为自然提取过程的最佳原材料。除了生物提取方法外,虾青素还可以通过化学合成或通过利用藻类、细菌或酵母的生物技术方法生产。近年来,随着重组 DNA 技术的进步,科学家们一直在研究基因工程技术以提高虾青素的产生。

由于其广泛的健康益处,在各个领域(包括医疗保健产品、制药、化妆品、食品添加剂、水产养殖)等各个领域的实际应用中;从而呈现出重要的经济价值和发展潜力。

虾青素是一种强大的抗氧化剂,对人体健康有很多好处,包括增强免疫力和对抗氧化应激。然而,食物中的虾青素含量和生物利用度各不相同,雨生红球藻目前被认为是虾青素最丰富的天然来源之一。

Astaxanthin Foods

Astaxanthin, as a nutritional supplement, is increasingly used in functional food and health care products because of its powerful antioxidant properties. Here are some types of foods that contain astaxanthin:

Nutritional supplements: Most commonly in the form of capsules, tablets or oral liquid, these supplements usually extract astaxanthin directly from Rhodococcus pluvialis and are taken as a daily health care.

Functional drinks: Some sports drinks or health drinks will add astaxanthin to promote its role of improving physical recovery, anti-fatigue or enhancing immunity.

Baked goods and cereal products: such as breads, cereals, energy bars, etc., may add astaxanthin as a nutrient strengthening ingredient.

Condiments and sauces: Some manufacturers may add astaxanthin to ketchup, salad dressings, or seasoning oils to increase the nutritional value and color appeal of their products.

Ready-to-eat food: As mentioned earlier, “astaxanthin steamed egg with Okra” is a creative dish that integrates astaxanthin into the daily diet, which is both beautiful and nutritious.

Candy and snacks: Some children’s nutritional gummies or healthy snacks will add trace astaxanthin, as one of the selling points to attract parents to buy.

Dairy products: Some yogurt or milk products will also add astaxanthin to increase the market competitiveness and health value of the product.

When choosing foods that contain astaxanthin, it is important to check the product label to know the specific source and content of astaxanthin, and whether there are other additives, to ensure that the selected product meets the individual’s health needs and preferences.
