The present invention relates to a method for producing a coffee-containing carbonated beverage. BACKGROUND ART Carbonated drinks containing coffee have been developed as new soft drinks. The coffee-containing carbonated beverages referred to here refer to all carbonated beverages that contain coffee, and include coffee-containing carbonated beverages that comply with the Fair Competition Code for the Labeling of Coffee Beverages, etc. by the Fair Trade Commission. This includes, but is not limited to, carbonated drinks containing 1% or more in terms of beans. This beverage is usually made by adding sweeteners, acidulants, colorants, flavorings, etc. to coffee extract or powdered coffee aqueous solution, then adding carbonated water or absorbing carbon dioxide gas to make carbonated water, and then bottled or canned. However, it has the following drawbacks. (1) Severe foaming occurs during manufacturing, when opening the bottle or can, and when drinking. (2) After production, secondary precipitation occurs, reducing the product value. (3) The flavor of coffee and the refreshing feeling of carbonated water do not match.
Bad flavor. (4) Product spoilage occurs. In order to solve these drawbacks, we have proposed (1) a method of adding antifoaming substances such as silicone resin and surfactants to the coffee liquid or syrup to suppress the foaming phenomenon; Enzyme treatment method (3) Methods of extracting coffee liquid with organic solvents such as ethanol and acetone have been proposed, but they have been found to be insufficiently effective in suppressing the foaming phenomenon and to cause secondary additions such as enzyme odor. It has drawbacks such as the occurrence of off-odor and off-taste derived from substances, and lack of the original flavor of coffee, and it cannot be said that a fully satisfactory method for producing carbonated drinks containing coffee has yet been developed. The inventors of the present invention have conducted studies to overcome the drawbacks of such conventional methods, and as a result, have completed the present invention, which is highly effective. That is, in the present invention, an aqueous coffee solution is passed through an ultrafiltration membrane having a molecular weight cut-off in the range of 4,000 to 50,000,
The present invention provides a method for producing a coffee-containing carbonated beverage, which comprises carbonating the obtained coffee aqueous solution. The coffee aqueous solution used in the method of the present invention includes:
Usually, coffee extract or an aqueous solution of powdered coffee is preferably used. The concentration of coffee in such an aqueous coffee solution is not particularly limited, but is usually preferably about 5 to 30% by weight of solids. The essence of the present invention is to pass the coffee aqueous solution through an ultrafiltration membrane having a molecular weight cut-off in the range of 4,000 to 50,000. In particular, the molecular weight cut-off exceeds 5000.
More remarkable effects can be obtained when using an ultrafiltration membrane of 20,000 or less. By passing through an ultrafiltration membrane having such a selected molecular weight cut-off, components that cause foaming and secondary precipitation in coffee-containing carbonated beverages, such as pectin, protein, and high-molecular tannin, are removed. It effectively removes the coffee-specific flavor and taste substances retained in the coffee aqueous solution and retains them in the liquid without removing them.
The effect is that the flavor blends with carbonic acid and increases the cooling sensation. The material for the ultrafiltration membrane may essentially be any material with a molecular weight cut-off within the above range, but membranes made of heat-resistant materials that can be sterilized are preferred, such as polyvinylidene fluoride membranes. is preferably used. Any type of ultraviolet device may be used.
Appropriate modules such as tubular type, spiral type, hollow fiber type, etc. can be used. Ultrafiltration is usually carried out at a temperature of 20 to 70°C and an operating pressure of 10 kg/cm 2 or less. Sweeteners, acidulants, colorants,
A coffee-containing carbonated beverage can be obtained by adding flavoring agents and the like, and adding carbonated water or absorbing carbon dioxide gas to make carbonated water. The coffee-containing carbonated beverage thus obtained is appropriately bottled or canned to produce a product. The effects of the present invention can be summarized as follows. (1) Check for any foaming phenomenon during manufacturing, opening the product, opening the can, and drinking, and if foaming occurs, it disappears immediately. (2) The occurrence of secondary precipitation in the product is extremely low. (3) The flavor blends well with carbonated water and increases the refreshing feeling. (4) Ultrafiltration membrane removes microorganisms and prevents spoilage. EXAMPLES The present invention will be explained below with reference to Examples, but these Examples do not limit the present invention in any way. Example 1, Comparative Example 1 12 kg of coffee extract (B x 20°, coffee content 70% in terms of green beans) was passed through an ultrafiltration membrane made of polyvinylidene fluoride (tubular type, molecular weight cut off 18000,
