Abstract

The invention discloses a beverage prepared from purple corn and wheat germ and processed by ultrahigh pressure and a preparation method of the beverage and belongs to the technical field of food processing. The preparation method of the beverage prepared from purple corn and wheat germ and processed by ultrahigh pressure takes purple corn kernels and wheat germ as main raw materials and comprises the following steps: sorting raw materials, preprocessing the raw materials, carrying out pulping, gelatinization and enzymolysis, processing under ultrahigh pressure for the first time, centrifuging, adding sugar, an acidulant and a stabilizer and mixing, homogenizing and filling, and then processing under the ultrahigh pressure for the second time. The prepared beverage is abundant in nutriments including protein, amino acids, vitamins, microelements and dietary fibers necessary for a human body; the beverage is especially high in contents of anthocyanin and vitamin E and extremely high in health nutritive value and has the health functions of delaying senescence and scavenging free radicals; the ultrahigh pressure processing technology is adopted in preparation of the beverage prepared from purple corn and wheat germ, so that the activities of the anthocyanin and vitamin E in the beverage are retained to a great extent; meanwhile, the high protein of the wheat germ is fully used, thus improving the resource utilization rate.

Example Embodiment

[0031] Example 1
[0032] Select plump, moth-free purple corn, clean it, pre-cook and thresh it, weigh 80g for later use; select fresh wheat germ for microwave drying, with a thickness of 1cm during processing, a microwave power of 400W, and a processing time of 5min; Take the above-mentioned microwave-treated 100g wheat germ and soak it in 500ml quality purified water for 3 hours at a temperature of 30°C; mix the purple corn kernels and wheat germ, put them in a tissue masher, and then add 900ml of water to the colloid Refining in the mill to obtain purple corn wheat germ slurry, then gelatinize the purple corn wheat germ slurry, gelatinization temperature: 80℃, gelatinization time: 30min, add 3600U vigorous medium temperature α- to the gelatinized slurry Enzymatic hydrolysis with amylase, enzymatic hydrolysis time is 120min, enzymatic hydrolysis temperature is 55℃; the mixed slurry after enzymolysis is subjected to ultra-high pressure treatment, ultra-high pressure is 100MPa, ultra-high pressure time: 10min, ultra-high pressure temperature: 30℃, Prepare the enzyme-inactivating mixed slurry; then centrifuge the mixed slurry after the ultra-high pressure treatment at a speed of 3500r/min for 20 minutes, and collect the upper layer slurry; add 30g sugar and 0.4g citric acid to the upper layer slurry collected after centrifugation , 2g of linseed oil is blended and concentrated to 1L with a rotary evaporator to obtain a purple corn wheat germ beverage. The blended beverage is homogenized. The homogenization pressure is 30MPa and the homogenization time is 8min. Bottle filled beverages; then use ultra-high pressure for sterilization, the pressure is 400MPa, ultra-high pressure time: 15min, ultra-high pressure temperature: 37 ℃, made into aseptic beverage, wipe the can and keep it warm for 7 days, and then it can be packaged Become a beverage product.
