Abstract
The invention discloses an eel complete nutrition powder, which comprises the following compositions in percentage by weight: 45 to 70 percent of eel protein, 8 to 15 percent of eel fat, 5 to 30 percent of drying aid, 0.06 to 0.1 percent of emulsifier, 0.5 percent of beta-cyclodextrin, 0.2 to 0.22 percent of essence, 0.2 percent of thickening agent, and the balance being water. The invention takes fresh and alive eel in fresh water as a raw material to prepare the nutrition powder containing complete nutrient content of eel; and the eel complete nutrition powder not only contains complete protein of the eel, but also contains a great deal of eel fat, and has double functions of nutrition and health care. The product has good solubility, no fishy smell or other peculiar smell, and convenient use, and can be used as a functional energizing agent to be added into milk, milk beverage, infant foods and other health products.
Description
Technical field
The present invention relates to the converted products of a kind of eel, particularly relating to a kind of main finger is raw material with the eel, the solubility powdery product-eel full nutrient powder that utilizes the modern food engineering to process.The application of this product very extensively not only can be used in the infant food, and is also available in old food and health food, has the nutrition of eel, and advantages of easy digesting absorbs again.
Background technology
Eel is the very high fresh-water fishes of a kind of nutritive value, have the good reputation of " genseng in the water ".At present, domestic eel product mainly contains roast eel, freezes eel, and product category is single relatively, and this has directly limited the development of eel industry.Therefore, develop new product, increase the eel consumption figure, widen eel market and have great importance for the sound development of eel industry.
Eel has special nutritive value, and the powdered food that eel is processed into instant edible helps developing the market of baby food food, old people food and the health food of eel.Because the fat of eel is considered to the major function composition of eel, and human body is had many beneficial functions, therefore, when eel is processed nutrient powder, except will keeping protein wherein, also must keep its fat constituent.This makes the alimentary health-care function of eel full nutrient powder and the preparation of preparation method side and other fish nutrient powder or albumen powder be essentially different.
Summary of the invention
The object of the present invention is to provide a kind of new product--eel full nutrient powder of eel processing.This product is to be nutrient powder comprehensive nutrition, easy to use of feedstock production with fresh and alive, healthy eel.
The object of the present invention is to provide a kind of preparation method of eel full nutrient powder simple to operate, that be prone to realize.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The present invention is a kind of eel full nutrient powder, and its component and percentage by weight are: eel protein content 45-70%, and eel fat is 8-15%, and additive is 6-31%, and surplus is a water.
Used additive comprises drying aid 5-30%, emulsifying agent 0.06-0.1%, beta-schardinger dextrin-0.5%, essence 0.2-0.22%, thickener 0.2%.
Described drying aid is soluble starch or maltodextrin; Described emulsifying agent is tween, sapn, monoglyceride or sucrose ester; Described essence is orange flavor essence, breast flavor essence or careless enzyme essence.
A kind of preparation method of eel full nutrient powder, it may further comprise the steps: healthy eel alive is got in (1), and the gill and internal organ are slaughtered, removed to precooling to-3 ℃-3 ℃, is twisted into meat gruel with meat grinder; (2) in the fish gruel, add 0.5-10 water doubly, be warmed up to 30-70 ℃, add protease hydrolytic 1-12h and make eel disintegration, liquefaction prepare the eel hydrolyzate, boil the 2-10min enzyme that goes out; (3) hydrolysate is separated, carry out vacuum behind removal fish-bone, fish pomace, floating foam and the eel fat and concentrate, make it soluble solid content between 5%-40%; (4) add drying aid, emulsifying agent and other additives, liquid homogeneous, spray-drying just make the eel full nutrient powder of solubility.
Step (3) is not removed fat when hydrolysate is separated fully, but removes part fat, keeps part fat, has so both helped bellding and bonding phenomenon not occurring in following process, makes product have the health care of eel fat again.Be specially the eel fat of removing 60-80% with sedimentation-type centrifuge, keep the eel grease about 20-40%; This is the feature process of these other fish protein powders of preparation of product difference.
Before step (4) is carried out spray-drying to the eel hydrolyzate, must add drying aid and other additives carry out homogenization processing, fat is uniformly dispersed, the phenomenon of the inhomogeneous or bellding of Fat Distribution like this can not can in spray-drying and transporting procedures occur.This is the important process characteristic of these product other fish nutrient powder of difference or albumen powder preparation.
After adopting such scheme, the present invention has the following advantages:
The abundant nutrition that the present invention has eel is worth, and does not contain spur, does not have fishlike smell, and is easy to use, the form powdery, and dissolubility is good, can be applicable in infant food, old people food and the health food.Compare with other nutritious fish protein powder, this product also contains a large amount of eel fat except that containing protein, have the nutrition and health care dual-use function.On the technology, solved at pulverizing process bellding, eel oil oxidation, breathe out lose and fishlike smell and and powder process after technical barrier such as instant.
