Embodiment 1

[0034] Example 1: Coffee Beans of the Arabica and Robusta Crossbred Varieties of the Genus Katim P3

[0035] Step (1) Roasting: Heat the green coffee beans with hot air at 80°C for 15 minutes to dehydrate them, then pour them into rolling hot sand at 200°C to allow the dehydrated coffee beans to be heated evenly to produce aromatic substances and coffee crema through complex chemical reactions. The reaction time is 15 minutes. After the reaction, quickly sieve and discharge the coffee beans and the silver skin on the surface. Immediately after baking, cool with cold air to lock the fat.

[0036] Step (2) Grinding: Grinding the roasted and cooled coffee beans to a particle size of 20 mesh, then adding 6% deionized water to the first crushed coffee beans, stirring evenly and then crushing to 50 mesh.

[0037]Step (3) Enzyme conversion reaction: Stir the crushed coffee powder with 8% 95 alcohol evenly and place it in an open container to allow natural fermentation and enzyme con...

Embodiment 2

[0042] Example 2: Catim P4, a cross between Arabica and Robusta

[0043] Step (1) Roasting: Heat the green coffee beans with hot air at 100°C for 10 minutes to dehydrate them, and then pour them into rolling hot sand at 190°C to allow the dehydrated coffee beans to be heated evenly to produce aromatic substances and coffee crema through complex chemical reactions. The reaction time is 20 minutes. After the reaction, quickly sieve and discharge the coffee beans and the silver skin on the surface. Immediately after baking, cool with cold air to lock the fat.

[0044] Step (2) Grinding: Grinding the roasted and cooled coffee beans to a particle size of 10 mesh, then adding 5% deionized water to the first crushed coffee beans, stirring evenly and then crushing to 60 mesh.

[0045] Step (3) Enzyme conversion reaction: add 10% 90% alcohol to the pulverized coffee powder, stir evenly and place it in an open container to let it ferment naturally for 20 hours.

Embodiment 3

[0050] Embodiment 3: Robustas variety coffee beans

[0051] Step (1) Roasting: Heat the green coffee beans with hot air at 95°C for 15 minutes to dehydrate them, then pour them into rolling hot sand at 210°C to allow the dehydrated coffee beans to be heated evenly and complex chemical reactions will occur to produce aromatic substances and coffee crema. The reaction time is 20 minutes. After the reaction, quickly sieve and discharge the coffee beans and the silver skin on the surface. Immediately after baking, cool with cold air to lock the fat.

[0052] Step (2) Grinding: Grinding the roasted and cooled coffee beans to a particle size of 10 mesh, then adding 5% deionized water to the first crushed coffee beans, stirring evenly and then crushing to 60 mesh.

[0053] Step (3) Enzyme conversion reaction: add 10% 90% alcohol to the pulverized coffee powder, stir evenly and place it in an open container to allow natural fermentation and enzyme conversion for 6 hours.

Abstract

The invention discloses a method for efficiently extracting caffeine in coffee deep processing, and the method comprises the following steps: (1) baking coffee beans; (2) carrying out enzymatic conversion reaction; and (3) adding a distillation separator column in supercritical fluid extraction equipment, and obtaining coffee oil, caffeine and caffeine-free or low-caffeine coffee. The invention has the advantages of high efficiency, safety, no toxicity and no additive, the coffee is divided into the coffee oil, the caffeine and the caffeine-free or low-caffeine coffee by supercritical fluid extraction. The method is high in recovery rates of the coffee oil and the caffeine, and the brewing mouthfeel and flavor of the extracted coffee beans/powder are not affected. Therefore, stable coffeeoil, caffeine crude products and low-caffeine/caffeine-free coffee can be produced to be in line with industrial production and application, greatly improving economic value of the coffee.

Description

technical field [0001] The invention relates to the field of food, in particular to the technology of obtaining high value-added products through deep processing using coffee beans as raw materials. Background technique [0002] Coffee is fragrant and delicious, and it is an indispensable beverage and food for modern people's life. Coffee also has the effects of refreshing, anti-cancer, and reducing the risk of diabetes. It is a healthy food in the new era. Coffee can also be further processed to make more high-value products. [0003] Coffee is rich in water-insoluble oil and has a strong volatile aroma. It is an important natural flavor resource and is widely used in the flavor and fragrance food additive industry. However, when making beverages, most of the oil remains in the coffee grounds and is discarded because it is insoluble in water, and it is not fully utilized to cause waste. In addition, coffee is rich in caffeine (Caffeine). Caffeine (also known as caffeine)...
