Description

Technical Field

[0001] The invention belongs to the technical field of compressed biscuits, and particularly relates to an anti-fatigue compressed biscuit containing highland barley extract and a preparation method thereof. Background Art

[0002] Highland barley is one of the varieties of the wheat family of the Poaceae family, and can also be divided into hulled and hullless barley or highland barley. Highland barley can be divided into two-row naked barley, four-row naked barley and six-row naked barley. China mainly produces four-row naked barley and six-row naked barley. According to color, it can be divided into white, black and blue. The main producing areas account for more than 80% of the planting area. Its unique ingredients, such as β-glucan, protein, aromatic polyphenols and other active substances. For a long time, highland barley has been mainly used to make tsampa powder for consumption, and this consumption method has limited the geographical scope of highland barley consumption. Compressed biscuits, as a high-energy convenience food, have the advantages of being suitable for long-term storage and transportation, easy to carry, and quick to eat. They can also serve as emergency rescue under special conditions. And with the continuous improvement of compressed biscuit technology and formula, compressed biscuits are becoming more and more popular among consumers. Using a variety of active substances contained in highland barley to make compressed biscuits is conducive to broadening the application range of highland barley. The extraction of highland barley extract often requires high-temperature spray drying to obtain highland barley extract powder. The spraying process has caused the aromatic polyphenols in the highland barley to volatilize, resulting in losses and reducing the effect of highland barley products. Summary of the invention
