Embodiment 1

[0037] Prepare 100 kg of protein nutritious food, use Dumas Nitrogen Analyzer to determine the N content of raw material whey protein and soy protein isolate as N milk And N beans , According to the above principle that is N milk =N beans Calculate the content of raw materials required for 100 kg of isonitrogen and double protein nutritious food, and use the N measured in the present invention Isolated Soy Protein / g = 0.12 and N Whey Protein / g=0.10 as an example, to prepare 100 kg of isonitrogen and double protein nutritious food requires weighing 45.4 kg of soy protein isolate and 54.6 kg of whey protein. Add 45.4 kg of soy protein isolate and 54.6 kg of whey protein into a 500 kg professional mixer, and mix for 15 minutes at 12 revolutions per minute.

[0038] According to needs, a fluid protein nutrient food is prepared according to the following method. The protein powder is added to the corresponding 50 degrees Celsius pure water and hydrated for 30 minutes to prepare di...

Abstract

The invention discloses a preparation method and an application of a protein nutritional food with an anti-fatigue efficacy, belongs to the field of functional foods and particularly relates to a food with a significant efficacy on sports fatigue relieving. The protein nutritional food prepared by adopting the method disclosed by the invention comprises the following main nutritional base materials in parts by weight: 44-46 parts of soy protein isolate and 53-55 parts of whey protein according to the detection of the nitrogen content of each protein. By adopting the protein nutritional food with equal nitrogen ratio, through seven-week nutrition intervention in a rat after loaded swimming in still water, the lactic dehydrogenase activity in the rat can be remarkably increased and the loaded swimming exhaustive time of the rat is prolonged on the premise of not increasing the weight of the rats. The food has an obvious efficacy on sports fatigue relieving and the average loaded swimming exhaustive time of the rat is up to 135 seconds, so that the food has a good utilization value in anti-fatigue functional food development.

Description

Technical field: [0001] The invention belongs to the field of functional foods, and particularly relates to a significant effect on alleviating sports fatigue. Background technique: [0002] Intense exercise, high pressure and fast-paced modern life can all bring different degrees of fatigue to people. Exercise fatigue refers to the inability of the body's physiological process to maintain its predetermined exercise intensity. Fatigue cannot effectively alleviate excessive muscle tension, free radicals, lactic acid and other substances that ultimately affect the exercise effect. Therefore, in recent years, how to use nutritional means to develop functional foods to relieve exercise fatigue has become a research focus. [0003] Whey protein is a high-quality protein, containing eight kinds of amino acids necessary for the human body, and the ratio meets the needs of the human body. Whey protein is easily absorbed, can be quickly digested and degraded in the acidic environment of ...
