Relevant researches show that the process conditions of different varieties, sexes and parts of chickens or different cooking vessels, time, pressure and the like and the difference of pre-treatments such as pre-frying, vinegar soaking, enzymolysis and the like have obvious influence on the composition and the content of nutrient components and flavor substances in the chicken soup. Meanwhile, different filling modes, sterilization conditions and storage temperatures also affect the quality and shelf life of the chicken soup. The addition of the flavor enhancer in the food can enhance certain flavor characteristics of the food, such as persistence, mouthfeel, mildness and thickness. The flavor enhancers approved in China at present comprise sodium glutamate, sodium ribonucleotide, disodium succinate, animal and plant proteolytic enzymes and the like.
At present, domestic research on concentrated chicken soup mainly focuses on research on developing technical formulas and processes of concentrated chicken soup with different tastes and efficacies. For example, Liu Meng Jian et al (patent application No. CN201410785901.6) discloses a gastrodia elata and black-bone chicken soup medicated diet formula and a preparation method thereof. The invention is prepared by decocting angelica, eucommia and abalone shell with water to obtain concentrated juice; and then putting the viscera-removed black-bone chicken into the concentrated juice, adding the gastrodia elata, the Chinese date, the medlar and the fried jujube kernel in parts by weight, adding water, stewing, and adding salt to obtain the gastrodia elata and black-bone chicken soup medicated diet, wherein the medicated diet has the effects of strengthening bones and muscles, calming wind and arresting convulsion. For example, chenyuejie et al (patent application number CN201610546015.7) specifically discloses an instant cordyceps militaris chicken soup and a preparation method thereof. Adding the chicken pieces and the cordyceps militaris into water for cooking, separating chicken from chicken soup, concentrating the chicken soup to obtain concentrated chicken soup, adding additives into the concentrated chicken soup for adsorption, and drying to obtain the instant cordyceps militaris chicken soup. Compared with the original soup, the instant cordyceps militaris chicken soup prepared by the method has high retention rate of cordycepin, cordyceps polysaccharide and amino acid nitrogen.
