Abstract
The invention relates to a corn stigma and groundcherry tea and a preparing method of the corn stigma and groundcherry tea, and belongs to the field of beverage. The invention aims to solve the technical problems that when a juice beverage is prepared by using current groundcherry juice, preservatives and antioxygens need to be added, which can cause cancer; the functional components of current corn stigma tea are difficult to dissolve; and single corn stigma component is not ideal in blood glucose reducing effect. The product is prepared by corn stigma, groundcherry pericarp, tea and rebaudiana. The method comprises the steps of: 1, edulcorating, cleaning and dehydrating corn stigma sequentially, and then drying ultrasonically and smashing; 2, rinsing, drying and smashing the groundcherry pericarp; and 3, smashing tea and rebaudiana; 4, weighing materials and mixing the materials uniformly; and obtaining the corn stigma and groundcherry tea. The corn stigma and groundcherry tea can be stored for a long time and is convenient to carry, and groundcherry pericarp is effectively utilized. The functional components in the tea are easier to dissolve, and the functional components of materials are interacted, so that the blood glucose and blood fat reducing effect of the tea provided by the invention is remarkably improved compared with that of current corn stigma tea.
Description
Technical field
The invention belongs to field of beverage.
Background technology
Corn stigma contains multiple chemical composition to the human body beneficial, the compound of corn stigma Isolation and Identification mainly contains flavones and glycoside, sterol, alkaloid, carbohydrate, organic acid, volatile oil, trace element and multivitamin etc., has the effects such as diuresis, hypoglycemic, step-down.Corn stigma is as corn's by-products, and resource is huge.But at present very limited to its development and use, outside only being used as medicine on a small quantity, major part is abandoned in vain, has caused the wasting of resources and environmental pollution.Corn stigma have the source abundant, cheap, be easy to the advantage such as collection, corn stigma is carried out deep processing and comprehensive utilization, can avoid corn stigma to be discarded in vain and contaminated environment, have ecological benefits; Can improve simultaneously the corn planting benefit and increase farmers' income, have society and economic benefit.
Have cool blood after the corn stigma decoction, expel the heat-evil, the effect such as detumescence, but the functional component of corn stigma is wrapped in the fiber, in poach or hot-water soak process, functional component is difficult for stripping, the corn stigma efficacy effect is affected, and makes the corn stigma hypoglycemic effect not ideal enough.The function of reducing blood sugar composition of corn stigma mainly is corn silk polysaccharide, and composition is comparatively single, and the corn stigma hypoglycemic effect is affected.
Russule ma (having another name called wintercherry, wintercherry fruit or calyx) nutrition is very abundant, and according to surveying and determination, Vit C contents is 34.40 (MG/100ML) in its fruit, and the content of iron, magnesium, phosphorus, potassium (MG/ML) is respectively 1,60,110 and 460; Albumen, solid content, total reducing sugar (%) content is respectively 0.31,2.15,1.29, and total amino acid content is 216.88 (MG/L), and 18 seed amino acids, content are all very abundant, have 8 seed amino acids of needed by human; Have heat-clearing, detoxifcation, relieve sore throat, reduce phlegm, the function of diuresis.
At present, utilize russule ma pulp to make fruit drink, the easily oxidized and difficult long-time preservation of pulp fruit juice processed needs to add antioxidant and anticorrisive agent, might be carcinogenic.Owing to contain a large amount of moisture content among the russule ma, and be in conjunction with water mostly again, so the russule ma is difficult to be dried and pulverize, also be difficult to store at normal temperatures even if use freezing crushing technology to obtain pulverized russule ma powder, be very easy to moldy metamorphism, so be difficult to make bag tea.Solely drink corn stigma or russule ma skin tea-making, its hypoglycemic, lipid-lowering effect are also not obvious.
Summary of the invention
The present invention will solve existing russule ma pulp making beverage interpolation anticorrisive agent and the antioxidant of adopting and easily cause cancer; Bag tea is made in inconvenience; Corn stigma tea exists functional component to be difficult for stripping, corn stigma, russule ma skin functional component is single, hypoglycemic effect is undesirable technical problem; Thereby provide corn stigma russule ma tea and preparation method thereof.
Corn stigma russule ma tea is to be made by corn stigma, russule ma pericarp, tea and STEVIA REBAUDIANA, mixes by the percentage by weight by 85～90 parts, 5～8 parts, 2 parts and 1～5 part after corn stigma, russule ma pericarp, tea and STEVIA REBAUDIANA are processed respectively.
The preparation method of corn stigma russule ma tea is carried out in the steps below:
Step 1, corn stigma being carried out removal of impurities, cleaning and processed successively, is the ultrasonic wave of 200～400W, frequency 35～50kHz with power then, and the ultrasonic moisture that is dried to is 8%～10% under 40～60 ℃ of temperature, is crushed to particle diameter less than 60 orders again;
Step 2, russule ma pericarp is cleaned, again crushed after being dried to particle diameter less than 60 orders;
Step 3, tealeaves and STEVIA REBAUDIANA are crushed to respectively particle diameter less than 60 orders;
Step 4, by ratio of weight and the number of copies take by weighing russule ma pericarp after step 2 is processed of corn stigma after 85～90 parts of step 1 are processed, 5～8 parts, 2 parts after step 3 is processed tealeaves and 1～5 part of STEVIA REBAUDIANA after step 3 is processed after mixings; Obtain corn stigma russule ma tea.
The tea of the inventive method preparation is hypoglycemic, blood fat and blood pressure effect significantly improve.Product of the present invention does not need anticorrisive agent and antioxidant, can preserve for a long time, and is easy to carry.Adopt russule ma Normal juice to make fruit drink, russule ma pericarp is dropped as waste material, turns waste into wealth in the present invention, is effectively utilized.
Bag tea (5～10 g/bags) is made in the pack of corn stigma russule ma tea.
In the dry process of ultrasonic wave, the corn stigma interior tissue repeatedly be compressed with stretching action under form spongelike structure; Simultaneously also formed cavitation bubble in the corn stigma interior tissue, thereby intracellular pressure is increased, caused cell wall rupture, functional component is separated out in cell, is attached to the sponge structure surface.When with hot-water soak product of the present invention, functional component is separated out soluble in water from the sponge structure surface, thereby has increased the functional component stripping quantity.The present invention has selected russule ma pericarp as raw material, does not wherein contain a large amount of easily dryly in conjunction with the water capacity, and made bag tea never degenerates in normal temperature environment, does not go mouldy.The easier stripping of functional component in the tea of the present invention, the functional component of each material interacts, thereby hypoglycemic, the blood fat effect of the existing corn stigma tea of tea of the present invention are significantly improved.
