Embodiment

[0083] Follow these steps:

[0084] 1. Preheat the American DiedrichIR-12 semi-hot air roaster to 200°C, and then put in 10 kg of Yunnan Puer Arabica coffee beans or Vietnamese Robusta coffee beans;

[0085] 2. Green coffee beans absorb heat to lower the temperature of the roaster. The inflection point is when the temperature drops to a certain temperature and starts to rise gradually. Record the time required for the green coffee beans to be put into the roaster until the inflection point appears as 2 minutes. The inflection point temperature is 65°C;

[0086] 3. Based on the total roasting time of 16 minutes and the coffee beans reaching 230°C, the color of the coffee beans should be between 65# and 55# of the Agtron swatch to calculate the preset parameters:

[0087] Remaining baking time T 1 =(16-2)=14 minutes,

[0088] Warming interval C 1 =(230-65)=165°C,

[0089] Target heating rate = C 1 / T 1 = 11.8°C / min,

[0090] 4. Starting from 2 minutes, record the current...

Abstract

Anti-oxidative health coffee belongs to the technical field of coffee roasting, and is characterized by being obtained according to a roasting method comprising the following steps: putting coffee berries into a roaster when the roaster is 195 to 205 DEG C, wherein the highest temperature of the roaster is equal to or lower than 230 DEG C; controlling the temperature increasing rate of the roaster, so as to ensure that the coffee berries are well roasted 16 minutes after being put into the roaster; taking the well roasted coffee berries out of the roaster, wherein the colors of the roasted coffee berries taken out of the roaster range from 55# to 65# of Agtron color samples. The temperature increasing rate of the roaster is controlled according to the following steps: carrying out pilot roasting according to a default parameter obtained via calculation, determining an initial roasting parameter, modifying the determined initial roasting parameter to obtain an optimal roasting parameter at which the total content of obtained antioxidants can be the largest, and roasting according to the optimal roasting parameter. The anti-oxidative health coffee is high in anti-oxidative activity, and not only is drinkable, but also can be used in other manners to bring benefits to human bodies.

Description

technical field [0001] The invention belongs to the technical field of coffee roasting. Background technique [0002] Coffee is one of the most popular drinks in the world. It is generally believed that the main effect of coffee is to refresh the mind, but a large number of recent research results show that coffee is also the best source of antioxidants for people every day. Great health benefits. [0003] Antioxidants are important substances that resist free radicals or scavenge free radicals. The substances involved in antioxidation in the human body include antioxidant enzymes and non-enzyme antioxidant substances. [0004] Free radicals are also called "free radicals" in chemistry, and refer to atoms or groups with unpaired electrons formed by the homolysis of covalent bonds in the molecules of compounds under external conditions such as light and heat. Oxygen is an essential element for sustaining life, and when we inhale oxygen to supply our cells, free radicals are...
