Coffee processing

Green coffee processing is effected by either the dry or wet method. The dry method produces so-called natural coffees. The wet method usually produces the more uniform and higher quaUty washed coffees. 

Decaffeination Regulations. Eor decaffeinated roasted coffee, EEC standards indicate the maximum content of caffeine as 0.1% db for decaffeinated instant coffee it is 0.3% db. In the United States, decaffeination usually signifies that 97% of the caffeine has been removed. Permissible solvents for decaffeination processes are defined by national legislation, eg, EDA or EEC directive. The maximum residual solvent content after decaffeination, roasting, or instant coffee processing is to be kept within good manufacturing practice, ie, very low ppm levels or below at point of sale (46).

The three types of processes considered are a solids process - such as a process producing lime, a solid-fluid process - such as a powdered-coffee process, and a fluid process - such as a methanol-synthesis process. No sharp division exists among these process types so that you must use some judgment to classify a process. Table 2.6 contains average cost factors for these process types. The factors for process equipment depend on the material of constmction. Thus, Table 2.7... 

In a discussion of prior art, Peter and Brunner refer to an article (Sivetz, M. 1963. Coffee Processing Technology. Vol. 2, 21, Avi Publishing, Westport, CT) which describes the use of liquid CO2 to produce aroma oil from coffee however, they do not explain in the prior art section that the article describes aroma extraction from coffee which has been roasted. They then refer to a second article on the use of liquid CO2 to produce aroma concenuates, FoodTechnol, No. 23,11,50 (1969) and they write, Thus,...

Caffeine can he extracted from coffee, tea, and kola plants hy one of three methods. These methods are used primarily to produce the decaffeinated counterparts of the products decaffeinated coffee, decaffeinated tea, or decaffeinated soft drinks. A commercial variation of these procedures is to treat the waste products of tea or coffee processing, such as the dust and sweepings collected from factories, for the extraction of caffeine.

Feasibility studies have shown that, although the initial investment cost of the C02-based plant is higher, this process provides a better income and a higher gross profit per tonne of coffee processed than does the ethyl acetate-based process. The higher gross profit is mainly due to the excellent quality of both the coffee and the caffeine produced by the CO2 process and to the fact that losses in this process are negligible. In fact 85-90% of the extracted...
