Some people think that oil is an integral part of coffee flavor, but they also point to concerns about the health risks posed by the coffee oil.

Is "greasy coffee beans" good or bad? Should you choose coffee beans that are "oily" or "unoiled" in appearance? This time, starting from coffee beans, we will discuss with you how the baking and extraction process affects these oils, so as to understand the good and bad of these coffee oils.

● is not greasy coffee oil.

Coffee beans, like other seeds such as corn and soybeans, contain oil. However, the oil on the surface of coffee beans is not the same as that on espresso. The oil on the surface of coffee beans is a water-soluble organic substance that looks like an oil, while "coffee oil" itself contains many aromatic ingredients of coffee and can be dissolved in water. So the surface of your brewed coffee is not covered with greasy grease.

After the coffee is ground, the aroma and oil will begin to volatilize and release, and the flavor of the brewed coffee will gradually decrease with the release. Therefore, the existence of coffee oil is the easiest way to judge the quality of coffee.

The two most familiar coffees are Arabica and Robusta, which are low in caffeine (0.8-1.4%) and about 10% fat, while robusta caffeine contains 1.7-4%. Coffee oil is 60% less than Arabica. Arabica has become the first choice of glutton because of its low caffeine content and high fat flavor.

Two reasons for ● cause "oily coffee beans"

The oil content on the surface of coffee beans is generally affected by the baking method.

● 1. Stale shallow baked beans

The "shallow baked beans", which are light in heat and light brown in appearance, will not produce oil after baking, and the phenomenon of "dotted oil" begins to appear about six days after baking (dotted oil droplets appear on one side of the coffee bean). Slight "dotted oil" does not mean that it is not fresh, but sometimes the flavor of light-roasted coffee beans is at its peak. Continue to put, more than two weeks after the oven, the surface of shallow baked beans gradually covered with a bright glow, at this time, the flavor of "shallow baked beans" has begun to decline, should avoid buying or drinking as soon as possible.

In addition, in the process of roasting, coffee beans are partially dehydrated due to uneven heating. On the second to fifth day after baking, the oil content will also appear in a dotted way, which is different from the oil coming out of the whole surface of deep-cultured coffee.

Anyway, if the shallow roasted coffee beans appear in the above two situations, either the roasting is not good, or the date is not fresh, it is not recommended to buy.

● 2. Fresh deep-baked beans

The "dark baked beans", which are dark brown in appearance, show a slight glossy appearance after baking, and begin to produce a large amount of oil on the surface from the second day to the fifth day or so. When coffee beans are deeply baked, oil will be produced because of the high dehydration rate, so if deep-baked beans begin to produce oil on the surface in the first one or two days of storage, it is a normal phenomenon.

The oily "deep-baked beans" do not mean that they are not fresh. On the contrary, the deep-baked beans will gradually dry out three weeks after they come out of the oven, and eventually become dry and unoily, so if you see the coffee beans that are dry and not oily, but the appearance is dark brown, please pay special attention to whether they indicate the baking date, which is very likely to be spoiled beans.
