The invention provides a high-
germination-rate highland barley and hulless oat composite beverage and a production method thereof, belongs to the field of
food processing, and particularly relates to a production method of a cereal beverage. The production method comprises the following steps: with full-grain highland barleys and hulless oats with the
germination rate of 80% and 90% respectively as raw materials, baking for the first time; mixing the highland barleys with the hulless oats in a
mass ratio of 8:2 and baking for the second time; crushing and screening, and adding to 8-10 times of
water based on
mass to form a pasty type; carrying out same-batch
enzyme adding treatment and gradient enzymolysis treatment; adding mixed glue and a composite emulsifier hot water solution according to a ratio amount to highland barley and hulless oat composite feed liquid subjected to
enzyme deactivation treatment; adjusting the
sugar degree to 8% by
sucrose and making up to the volume so that the ratio of the raw materials accounts for 8% of the total amount of the materials; and performing secondary homogenization and UHT (Ultra
Heat Treated) sterilization and then filling. The high-
germination-rate highland barley and hulless oat composite beverage utilizes
crop resources which are safe and healthy in alpine regions and have very high
nutritive values, has a scientific formula and is novel in process; the defects of a traditional process are effectively avoided; the prepared composite beverage has balanced
nutrition, mellow mouth feel and good stability and the industrialization of the technology is easy to realize.
