However, the research on papaya plants at home and abroad mainly focuses on papaya fruit, and there are few reports on the functional components of papaya leaves.
[0003] my country's papaya is widely cultivated, but people only understand the health value of papaya, but do not pay attention to the stems and leaves with important medicinal value. Most of the stems and leaves are directly discarded after the fruit is harvested, causing great waste. It is necessary to develop and utilize

Embodiment 1
[0017] 1) Crushing and soaking: Take 500 grams of papaya leaves, wash them, grind them into a coarse powder, the particle size of the coarse powder is 30-50 mesh, add water, the ratio of solid to water is 1:10, soak at room temperature for 12 hours , to obtain the papaya leaf coarse powder soaking liquid, the papaya leaf is ground into powder and soaked to facilitate the soaking of starch and other substances, which is convenient for the extraction of the subsequent steps;
[0018] 2) Filtration and concentration: The papaya leaf coarse powder soaking solution obtained in step 1) is subjected to secondary filtration, and the filtrate is placed in a concentration device for concentration under reduced pressure, and the pressure is controlled at 50kpa. It is beneficial to carry out secondary treatment to make the papaya leaf The impurities in the soaking liquid are filtered out, and the pressure is controlled within a certain range to concentrate the nutrients in the papaya leave...

The invention relates to the field of deep processing of crops, in particular to a method for extracting amino acid of papaya leaves. The method comprises the following first step of smashing and soaking, the second step of filtering and concentrating, the third step of alcohol leaching, the fourth step of extracting and the fifth step of exchanging and eluting. By means of the steps of the method, papaya leaves are ground into powder and soaked, and substances such as starch can be easily obtained through soaking; secondary treatment is carried out so that impurities in a soaking solution of papaya leaves can be easily filtered out; the pressure intensity is controlled to be within a certain range, so that nutritional substances in papaya leaves are well concentrated in a concentrated solution, then necessary amino acid ingredients in the concentrated solution are diluted in an ethanol solution through quenching and alcohol diluting for extraction, the steps are precise, and amino acid ingredients in papaya leaves can be extracted; besides, extraction is sufficient, and wide development prospects are achieved.
Description
technical field [0001] The invention relates to the field of deep processing of crops, in particular to a method for extracting papaya leaf amino acids. Background technique [0002] In recent years, researchers in the United States and Japan have found that papaya leaf extracts have anticancer effects and are effective against a series of human tumor cells cultured in the laboratory, including cervical cancer, breast cancer, liver cancer, lung cancer, pancreatic cancer, etc. The concentration of the extract The higher the value, the more obvious the anti-cancer effect, but its anti-cancer principle and specific components that exert anti-cancer effects need further research. However, the research on papaya plants at home and abroad mainly focuses on papaya fruit, and there are few reports on the functional components of papaya leaves. [0003] my country's papaya is widely cultivated, but people only understand the health value of papaya, but do not pay attention to the st...
