什么是番茄红素

番茄红素的全称是“番茄红素”,它是一种红色的天然色素。针状深红色晶体,英文名称为番茄红素,之所以被称为“番茄红素”,是因为它最初是从番茄中分离出来的。番茄红素是目前在天然植物中发现的具有最强抗氧化能力的天然物质之一。番茄红素主要存在于番茄中,番茄中番茄红素的含量取决于番茄的种类和成熟度。例如,鲜红色西红柿每公斤含有50毫克番茄红素,而黄色西红柿可能只含有5毫克。其他含有番茄红素的植物包括西瓜、葡萄柚和番石榴。研究表明,每100克含番茄红素的水果中,番茄红素的含量分辨率为:番茄0.2-20毫克,西瓜2.3-7.2毫克,番石榴5.23-5.5毫克,木瓜0.11-5.3毫克,葡萄柚0.35-3.36毫克.

番茄红素的作用

一、番茄红素的摄入量

据统计,番茄和各种番茄制品占日常生活中番茄红素摄入量的85%。许多人习惯生吃西红柿。事实上,生吃西红柿只能吸收果肉中的维生素C,但不能获得番茄红素,一种西红柿中更有益的物质。不同于其他营养成分,如维生素C,它会在烹饪过程中流失,番茄食品加工反而会提高番茄红素的利用率。例如,新鲜番茄的含量约为30-50毫克,但在成品番茄中,如番茄酱约为490-940毫克,番茄汁约为10-110毫克,番茄酱约为50-230毫克。这是因为番茄红素不溶于水,但溶于油,并且与植物纤维紧密相连。因此,烹饪、打碎番茄和油脂的存在可以大大提高消化系统吸收番茄红素的能力。年龄小于25岁,身体健康,不建议服用番茄红素产品,每天吃1-2个成熟的番茄,少量的番茄红素,可能满足身体的需要。如果你超过35岁,每天10-20毫克的番茄红素是必要的营养,因为35岁以后,体内的番茄红素开始迅速减少,只有番茄红素可以从外部补充。

第二,番茄红素的好处

1.番茄红素抗氧化能力

人体不能产生番茄红素,番茄红素只能通过食物摄取。人体内的单线态氧和自由基是破坏人体自身免疫系统的罪魁祸首。番茄红素能捕捉物理或化学模式,有效淬灭单线态氧,抑制自由基的产生或直接消除自由基等。发挥抗氧化作用。番茄红素可以取代发散电子的激发,产生基态氧或三重态氧番茄红素。三氧番茄红素可以消除数千个单线态氧自由基。因此,番茄红素通过其抗氧化能力,可以有效地保护生物膜不受氧自由基的影响,延缓细胞和人体的衰老。研究表明,含有分裂番茄红素的饮食可以有效增加血清中番茄红素的含量,并有效降低氧化应激水平。番茄红素还具有消除次氯酸的作用,次氯酸可以通过修饰蛋清、脱氧核糖核酸和核糖核酸而导致心血管疾病中的组织氧化。番茄红素可以减少次氯酸造成的身体伤害。

2.番茄红素抗癌

番茄红素具有预防和抑制恶性肿瘤和癌症的作用。血液中番茄红素的浓度与前列腺癌、食道癌、胰腺癌、胃肠癌、乳腺癌、皮肤癌等的发病率呈负相关。特别是在预防前列腺癌方面。

3.番茄红素保护心脑血管疾病

番茄红素能彻底清除血管废物,调节血浆胆固醇浓度,保护低密度脂蛋白免受氧化,修复氧化细胞,促进细胞间胶体形成,增加血管弹性。番茄红素对局部脑缺血有保护作用。其主要过程是抗氧化和清除自由基,以抑制神经胶质细胞的活动和减少脑灌注损伤的面积。每天摄入不少于25毫克的番茄红素可相当于治疗高脂血症的低剂量他汀类药物,但剂量超过25-44毫克/天是否会降低高血压患者的血压仍需进一步研究。

4.番茄红素和前列腺

Medical research has found that lycopene can improve the quality of male sperm, mainly because lycopene content is very high in healthy male testes, but low in infertile male testes. Oral lycopene has positive results in the treatment of male infertility for unknown reasons, but the specific treatment plan still needs a large number of clinical experiments to determine.

5. Lycopene skin care

Lycopene also reduces the risk of skin exposure to radiation or ultraviolet rays. By eating foods rich in lycopene at ordinary times, when ultraviolet rays irradiate the skin, lycopene in the skin will cherish skin tissues from ultraviolet rays and erythema will occur. Lycopene also quenches free radicals in epidermal cells and has a significant fading effect on senile color spots.

Third, lycopene side effects

Lycopene is a pure natural health product, so it has no side effects. However, lycopene is required by the human body in an amount of 6mg every day. Excessive intake is not beneficial to the human body. In 2004, many experts from Shandong Center for Disease Control and Prevention conducted toxicological tests on the safety of lycopene. The tests showed that lycopene was nontoxic, harmless and had no side effects.

Application of lycopene

I. Beverages, Food

In the food and beverage category, lycopene has been approved as "novel food" in Europe and GRAS status in the United States, and is most popular in non-alcoholic beverages. Data show that there are 7 categories of bread and breakfast cereal. There are 7 kinds of processed meat, fish and eggs. There are 7 categories of milk products. There are 6 categories of chocolate and candy. 5 kinds of sauces and seasonings; There are 5 kinds of dessert and ice cream. The patent of our country introduces an application method of lycopene in milk products, which not only connects the nutrition of milk products but also enriches its health care function.

II. Health Care Drugs

At present, lycopene is widely processed into various kinds of health care drugs, such as: American Plexiglain Soft Capsule, 89 yuan/Bottle, Corrected Lucerne Soft Capsule, 51 yuan/Bottle, Red Drink Liquid Lycopene Beverage, 298 Yuan/Box, etc. which are not listed here.

Xinjiang lycopene

The lycopene in Xinjiang is the best. As far as tomatoes are concerned, 30-42 degrees north latitude is the most suitable area for planting and processing tomatoes on the earth. However, Xinjiang, China, with sufficient sunshine and wide temperature difference between day and night, has cultivated Xinjiang tomatoes with large fruit shape, high eggplant red pigment content and high solid content.
