Technical Field

The invention relates to the technical field of food, in particular to a salted egg yolk malt sandwich biscuit and a preparation method thereof.

Background

The biscuit has the characteristics of storage resistance, portability, diversified tastes and the like, and is popular with people. The variety of biscuits is developing towards leisure and functional food. The sandwich biscuit is a trend, not only has good taste, but also can perfectly combine the crisp taste of the biscuit with the sandwich taste, and the existing biscuit sandwich mainly takes grease and jam as main materials, so that the taste development of the biscuit is limited.

Salted eggs are also called salted eggs and flavored eggs. The ancient name of salted Zi is a large amount of traditional reproduced eggs in China, and has the characteristics of freshness, fineness, tenderness, looseness, sand, oil and the like, in other words: the salted duck eggs are cut after being cooked, the egg yolk and the egg white are clear, the egg white is fresh and tender, the egg yolk is vermilion, or orange yellow and flowing oil, the taste is delicious, the salted duck eggs are always popular in the long cultural history of China, and the salted duck eggs are also always popular in the market as table food.

Besides being delicious and mellow in egg fragrance, the salted eggs serving as a food with the traditional Chinese characteristics have the effects of nourishing yin, clearing away the lung-heat and enlarging the skin and also have high nutritional value. Research shows that the salted egg yolk not only contains high fat-soluble vitamins (vitamin B2), lecithin, unsaturated fatty acid, protein, polypeptide and amino acid which is easy to be digested and absorbed by human body, but also contains rich trace elements such as manganese, phosphorus, calcium, iron and other vitamins.

In life, the nutrient elements in the salted egg yolk are convenient to obtain and low in price, and are good nutritional supplements. For example, salted egg yolk contains a large amount of nutrients, i.e., phospholipids and sterols. The phospholipids lecithin, cephalin and neurophospholipid are important for the growth and development of human body, and are important substances essential for the activity of brain and nervous system. Sterols are important components in the synthesis of steroid hormones in the body. In addition, researches show that the salted egg yolk contains more abundant unsaturated fatty acids, and the unsaturated fatty acids, especially conjugated linoleic acid, DPA, DHA and the like, have good functions of preventing cancers, diabetes and atherosclerosis, reducing body fat, increasing protein content and the like.
