Description

A method for processing functional beverage containing embryo extract Technical Field The invention relates to the technical field of beverage preparation, in particular to a processing method of a functional beverage containing embryo extract. Background The functional beverage has drinking function and nutrition and health care value, so the market demand is continuously rising, and the efficient development and application of natural active ingredients are the core direction of industry development. The corn germ is used as a high-quality byproduct generated in the corn processing process, is rich in high-quality protein, active peptide, vitamins and various mineral substances, and the active peptide substances have good physiological activity and are ideal raw materials for preparing functional beverages. However, the development of functional beverages by using corn germs as raw materials still faces a series of technical bottlenecks, namely firstly, lipid and lipoxygenase which are rich in corn germs are extremely easy to generate oxidation rancidity in the processing and storage processes, so that not only can rancidity phenomenon be generated, but also active nutritional ingredients can be damaged, and the conventional inactivation methods such as hot air drying and the like are inaccurate in temperature control, so that the outer layers are easy to be overheated and coked, and endogenous enzymes are easy to inactivate, and secondly, in the key enzymolysis step for extracting active ingredients, the conventional production process is mostly dependent on fixed time, temperature and pH parameters, and lacks effective real-time monitoring on enzymolysis progress, and due to the difference of raw material batches, the fixed process mode is easy to cause insufficient enzymolysis, low active peptide yield and unstable product quality. CN116774662a discloses a functional beverage preparation system containing embryo element, a preparation module, a detection module, an adjustment module, and a determination module for calculating average uniformity G of a preset number of bottled beverages according to corresponding parameters obtained by the detection module, determining whether the operation parameters of the preparation module meet preset standards according to the obtained average uniformity G, and when the operation parameters of the preparation module are primarily determined not to meet the preset standards, performing secondary determination on the operation parameters of the preparation module according to the maximum gray value obtained by the visual detection mechanism to determine whether the operation power of the stirring mechanism is adjusted, and when the operation parameters of the preparation module are primarily determined to meet the preset standards, determining whether the operation parameters of the component preparation unit meet the preset standards according to embryo element content of a single bottled beverage, thereby improving the production efficiency and qualification rate of beverage preparation.

In order to achieve the above object, the present invention provides a method for processing a functional beverage containing embryo extract, comprising: Separating corn germs from corn kernels, drying the corn germs, and carrying out microwave with preset microwave power to obtain inactivated corn germs; Collecting the peroxidation value of the oil of the inactivated corn germs, and obtaining an oxidation risk representation value of the inactivated corn germs; When the preparation of the inactivated corn germs does not meet the preset standard according to the oxidation risk characterization value, increasing preset microwave power or discarding the inactivated corn germs; Crushing and breaking the wall of inactivated corn germs meeting preset standards to obtain germ powder, and carrying out enzymo
