Dietary fiber minced fish vegetable biscuit and preparation method thereof
Technical Field
The invention relates to the technical field of food processing, in particular to a minced fillet biscuit and a preparation method thereof.
Background
The biscuit market is rapidly developed in China, more and more people are used to the biscuit as meal replacement food, the components of the common biscuit cannot meet the requirements of consumers, and more balanced nutrition and functions are required by modern people, such as addition of trace mineral substances such as iron and zinc; increasing the amount of supplementary protein; increasing the supplement vitamin; there is also a need for foods that are as low in sugar and fat as possible and small in molecular weight. As such, the biscuit industry has begun to have a functional transition, and health, nutrition, and health biscuits are gradually becoming the main development and competitive direction of the biscuit industry.
Pineapple is widely planted in China, fruits of the pineapple are extremely intolerant to storage, the fresh pineapple is mainly sold, and the shelf life of the pineapple is short after the pineapple is completely ripe. The processed products mainly comprise canned sweet water pineapple, pineapple juice and the like. A large amount of pineapple peel residues are generated in the processing process, and account for 50% -60% of the weight of the whole fruit, however, the pineapple peel residues are mostly discarded as wastes, so that the environmental pollution is caused, and meanwhile, the resources are greatly wasted. The related research shows that the pineapple peel contains abundant saccharides, protein, pectin, vitamins, minerals, cellulose and pigment substances, the nutrient components are basically similar to those of the pulp, and the content of crude protein and ash content is higher than that of the pulp.
The minced fillet is a novel raw material of the aquatic product conditioning food, has rich nutrient components, and is suitable for being made into fish balls, fish cakes, fish sausages, fish rolls and the like. At present, surimi is used for making surimi biscuits, but the fishy smell of surimi causes the surimi biscuits to have poor taste and flavor, and the appetite of consumers is seriously influenced.
Disclosure of Invention
In view of the above, the invention aims to provide a dietary fiber minced fillet vegetable biscuit and a preparation method thereof. According to the minced fillet biscuit provided by the invention, the minced fillet, the pineapple peel residue soluble dietary fibers and the vegetable juice are reasonably matched, the problems of heavy fishy smell and poor taste and flavor of the traditional minced fillet biscuit are solved, new nutrient elements are added, and the prepared biscuit is fragrant and thick in taste, crisp in taste, good in color and luster, uniform in tissue state and deeply popular with consumers.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
the invention provides a minced fillet biscuit which is prepared from minced fillet, soluble dietary fiber of pineapple peel residue, vegetable juice, low-gluten flour and other acceptable auxiliary materials in food.
According to the minced fillet biscuit provided by the invention, the minced fillet, the pineapple peel residue soluble dietary fiber and the vegetable juice are reasonably proportioned, so that the fishy smell of the minced fillet is effectively covered, the prepared minced fillet biscuit has unique fish flavor and crisp taste, and the problems of heavy fishy smell and poor taste of the existing minced fillet biscuit are solved.
