Abstract

The invention which relates to a production method of a solid Nelumbo nucifera Gaertn-Zea mayes L. saeeharata Sturt composite beverage and a product thereof belongs to the field of deep processing of agricultural products. The production method comprises the following steps: 1, preparing a Nelumbo nucifera Gaertn juice and a Zea mayes L. saeeharata Sturt juice; 2, respectively carrying out vacuumreduced pressure concentration on the Nelumbo nucifera Gaertn juice and the Zea mayes L. saeeharata Sturt juice; 3, blending the two juices in proportion; 4, spray-drying the well blended material according to an inlet air temperature of 180-185DEG C, a compressed air flow of 430-460L/h, a feeding flow of 450-500mL/h, a maltodextrin addition proportion of 50-60%, a material liquid temperature of 40-65DEG C and a stirring speed of 600-650r/min; and 5, carrying out nitrogen-filled packaging on the obtained solid Nelumbo nucifera Gaertn-Zea mayes L. saeeharata Sturt composite beverage. In the product of the invention, nutrient components of raw materials of Nelumbo nucifera Gaertn and Zea mayes L. saeeharata Sturt are effectively preserved. The product which has various nutrition and healthcare functions has the advantages of carrying convenience, good flavor, good instant solubility, drinking convenience and the like.

Description

1. Technical field [0001] The invention relates to a production method of a lotus root sweet corn composite solid beverage and a product thereof, belonging to the field of deep processing of agricultural products. 2. Background technology [0002] Lotus root (Nelumbo nucifera gaertn) originates in India. It has been cultivated in my country for more than 3,000 years and has a wide distribution. The lotus root cultivated in Jiangsu, Zhejiang, Hunan, Hubei and other provinces is the most important aquatic vegetable in my country. The nutrients of lotus root are rich and comprehensive, mainly including starch, sugar, protein (including 17 kinds of amino acids such as arginine and tyrosine), fat and lecithin, and a small amount of alkaloids, flavonoids, carotene and riboflavin. , Niacin, vitamin C, vitamin B. The medicinal value of lotus root is also quite high. It is cold in nature and has the effect of clearing heat and cooling blood, and can be used to treat febrile diseases...

Problems solved by technology

At present, Chinese patents CN 102018206A, CN 101164447A, CN 101167577A and CN 101711564A have respectively announced the method of using lotus seeds, red dates, sweet-scented osmanthus, spirulina, papaya, etc. The product is obtained after the drying, pulverizing and blending process, and the nutrients in the raw material cannot be well preserved and utilized. However, the spray drying technology adopted in the present invention has the characteristics of short drying time and relatively low drying temperature. Heat-sensitive materials such as lotus root and sweet corn can well preserve their nutrients and bioactive components
