CN105558157A - Preparation method for food additive of Pu'er tea instant product with adopting of aged-aroma volatile oil and excipient - Google Patents

Abstract

The invention discloses a preparation method for a food additive of a Pu'er tea instant product with adopting of aged-aroma volatile oil and an excipient. The preparation method of the food additive comprises the steps: 1) putting ripe tea of Pu'er tea after pile fermentation into an extract tank; 2) adding water with the amount 1-20 times the weight of tea leaves, and soaking the tea leaves; 3) boiling the tea leaves for 0.5-20 hours, and cooling steam with circulating water to obtain distilled liquid; 4) transferring the distilled liquid to a leaching tank, adding a leaching solvent with the amount of 0.1-10 times the volume of the distilled liquid, and leaching an aged-aroma component from a water phase; 5) standing and layering, then removing the water phase, then removing residual water in an organic phase with an organic solvent drying agent, filtering and separating the drying agent, calcining at the temperature of 200 DEG C, and recycling the drying agent; 6) in a concentration tank, carrying out reduced pressure or vacuum concentration distillation recycling of an organic solvent at the temperature of 0-50 DEG C, to obtain the aged-aroma volatile oil; and 7) mixing evenly the aged-aroma volatile oil and the excipient (volatile oil:excipient=1:100), and passing through a 60-200 mesh sieve, to obtain granular or powdery aged-aroma type food additive.

Description

A kind of for adopting the food additives preparation method of the Pu'er tea instant product of Chen Xiang volatile oil and excipient

Technical field

The present invention relates to food additives, particularly a kind of for adopting the food additives preparation method of the Pu'er tea instant product of Chen Xiang volatile oil and excipient, belong to technical field of food additives.

Background technology

Pu'er tea is the large leaf tea that Lancang River Watershed comprises the ground such as Simao, Yunnan, Lincang, Pu'er, Xishuangbanna and produces.Because finding a good sale in the distribution centre of various places in Pu'er county, Yunnan, therefore named Pu'er tea, can remove the superabundant fats in human body, the ripe tea of Pu'er tea is the tea product through holding heap fermentation, and it is vivid red dense that its millet paste can be slaked thirst and help produce saliva and carry to Pu'er tea, color and luster crow, its fragrant aroma, fragrant plough is unique, prolonged resistance to bubble.Pu'er cooked tea quality is had a distinctive style, and the mellow Hui Tian of flavour, makes us after drink enjoying endless aftertastes.And also have important health care, be considered to most one of local tea variety having Development volue.

Summary of the invention

The present invention is based on existing food additives formula, adopt the principles of science of novelty, propose a kind of for adopting the food additives preparation method of the Pu'er tea instant product of Chen Xiang volatile oil and excipient, it can add in Pu'er tea instant product easily.

The technical scheme that the present invention solves the employing of its technical problem is:

For adopting a food additives preparation method for the Pu'er tea instant product of Chen Xiang volatile oil and excipient, the preparation method of described food additives is:

1) the ripe tea of Pu'er tea through pile-fermentation is dropped in extractor;

2) 1 is added---the water soaking tealeaves of 20 times of tealeaves weight;

3) tealeaves 0.5 is boiled---20 hours, by circulating water steam, obtain distillate;

4) distillate being proceeded to extractor, adds 0.1---the extractant of 10 times of distillate volumes, extracts Chen Xiang composition from aqueous phase;

5) remove aqueous phase after stratification, then remove moisture residual in organic phase with organic solvent drier, isolated by filtration drier, drier is reclaimed in 200 degrees Celsius of calcination;

6) in concentration tank, 0---50 degrees Celsius of decompressions or Vacuum Concentration Distillation recovery organic solvent, obtain Chen Xiang volatile oil;

7) Chen Xiang volatile oil and excipient being mixed (volatile oil: excipient=1:100), cross 60---200 mesh sieves, obtain particle or Powdered Chen Xiang plough food additives.

Advantage of the present invention is: the present invention can add in Pu'er tea instant product easily, and easy to operate, simplifies production link, reduces production cost, economize in raw materials.

Detailed description of the invention
