Small fruit coffee seed powder characteristics: the raw product is yellowish green and the baked product is brown.

① has many brown lumps of different sizes.

② fiber is slender.

③ stone cells are rectangular and round, with a length of 200 μ m and a diameter of 20-40 μ m.

④ endosperm cell wall is thick, pit can be seen, containing protein grains and fat. Physical and chemical identification to take a little powder of this product, put on the slide, add a little water, heat, wait for the water to dry, add 2 drops of benzene, after drying, there are many yellowish needle crystals along the edge of the slide. Check for caffeine.

Apart from the climate, topography is the second most important factor we need to examine. Coffee trees are not suitable to grow on the cold current passageway, open to the south, frost-free and calm hillsides in winter are undoubtedly the first choice for planting, but the backside is sometimes a good choice because of the slower growth period. Although I have seen many slopes of more than 30 degrees in coffee growing areas around the world, the slope is too steep for planting, harvesting and soil conservation. When planting coffee trees in Yunnan, China, the slope is emphasized to be less than 25 degrees.

Most of the coffee producing areas in the world are located in the tropics between the Tropic of Cancer and the Tropic of Cancer, which we call the "coffee belt" or Coffee Belt or Coffee Zone in English. As a tropical cash crop, coffee trees grow in coffee belts with excellent climatic conditions, where the sun shines all the year round, has abundant calories and sufficient Rain Water, and the annual average temperature is above 20 degrees Celsius. However, high temperature, humidity and strong light can not be tolerated by any variety of coffee trees. For example, some Arabica coffee trees are not resistant to high temperature and humidity, and are often planted at higher elevations. Shade treatment is also needed, hence the name "Rainforest Coffee" and "Shade planting Coffee"

Caffeine can enhance the working ability of human skeletal muscles and increase the twitching tension of cats that indirectly stimulate the quadriceps. At the therapeutic dose, both caffeine and theophylline can improve the contractility of human diaphragm and reduce diaphragm fatigue. In addition, methylxanthine compounds, especially theophylline, have diuretic effects, which increase the excretion of water and electrolytes similar to thiazines. long-term drinking coffee can increase the concentration of plasma cholesterol, but this is not caused by caffeine. it has something to do with other ingredients in coffee.
