Problems solved by technology

[0003] Existing health care products with tea as the main functional ingredient, such as tea pillows and eye pillows, use dry tea raw materials as fillers, which are very easy to absorb moisture and deteriorate. The appearance design of the pillow requires a high degree of sealing, which hinders the release of volatile substances in the tea
At the same time, using a large amount of tea raw materials as filling also reduces the utilization efficiency of tea and increases the cost of health care products

preparation example Construction

[0016] The preparation method of the slow-release type tea-containing plastic particles of the present invention has the following steps:

[0017] 1. Take each component according to the mass ratio of tea powder: binder: foaming agent: 10-40: 50-80: 5-10, wherein the tea powder is crushed from dry tea to Made of 200 mesh to 300 mesh, the binder is ethylene-vinyl acetate polymer material with a melting point below 100°C, and the foaming agent is inorganic foaming agent sodium bicarbonate.

[0018] 2. Fully stir the tea powder, binder and foaming agent evenly.

[0019] 3. Set the preheating temperature of the internal mixer to be 10°C higher than the melting point of the ethylene-vinyl acetate polymer material for preheating, and the mixed raw materials are fed into the internal mixer at a constant speed for refining for 5-10 minutes. After the adhesive is fully melted, set the molding shape and size of the screw extruder, extrude and cool to form.

Embodiment 1

[0021] Example 1: Take a certain amount of dried Tieguanyin tea leaves, crush them in a pulverizer, and sieve them to retain 200-mesh particles. Crushed Tieguanyin powder, EVA28-25 particles, foaming agent NaHCO 3 Mix evenly at a ratio of 10:80:10, add it to an internal mixer with a preheating temperature of 100°C, refine for 10 minutes, adjust the speed of the screw extruder to 40r / min, and set the diameter of the cylindrical shape to 2cm , extruded and cooled to form. Experiments have proved that the tea-containing plastic particles have the function of slowly releasing the active ingredients of green tea for a long time.

Embodiment 2

[0022] Example 2: Take a certain amount of Xinyang Maojian tea leaves, crush them in a pulverizer, and sieve them to retain particles between 300 meshes. Crushed Tieguanyin powder, POE8100 particles, foaming agent NaHCO 3 Mix evenly at a ratio of 40:50:10, add it to an internal mixer with a preheating temperature of 110°C, refine for 5 minutes, adjust the screw extruder speed to 30r / min, and set the diameter of the cylindrical shape to 2cm , extruded and cooled to form. Experiments have proved that the tea-containing plastic particles have the function of slowly releasing the active ingredients of green tea for a long time.

Abstract

The invention discloses sustained-release tea-containing plastic grains and a preparation method thereof. The sustained-release tea-containing plastic grains mainly comprise the following components in part by mass: 10 to 40 parts of tea powder, 50 to 80 parts of adhesive and 5 to 10 parts of foaming agent. Fine and dense pores are formed in the grains formed in the invention, so the tea powder in the grains can function, and the adhesion by the adhesive ensures the sustained-release effect of the active ingredients. As fillers, the sustained-release tea-containing plastic grains can reduce the consumption of tea leaves, have long service life and lower the requirement on the external material of tea health-care products.

Description

technical field [0001] The invention relates to a tea product, in particular to a slow-release tea-containing plastic granule with tea as the main functional component and a preparation method thereof. Background technique [0002] Tea has been widely accepted as a functional consumer product. Tea is rich in tea polyphenols, amino acids, carbohydrates, various vitamins, sterols, saponins, pigments and aromatic hydrocarbons. Drinking directly can refresh yourself, protect the cardiovascular system, regulate blood sugar levels, enhance immunity and fight cancer and other effects. The various volatile components in tea, mainly aroma substances, can play the role of driving away drowsiness, relieving fatigue, and concentrating thoughts after being absorbed by the human body. [0003] Existing health care products with tea as the main functional ingredient, such as tea pillows and eye pillows, use dry tea raw materials as fillers, which are very easy to absorb moisture and dete...
