The use of pepper and capsaicin

The experiment proved that the pepper can inhibit the growth of some microbial pathogenicity.

Human use pepper spices have been at least 8,000 years. At the beginning, they used wild pepper. Placed in the production of potatoes, corn and cereals. Archaeologists said that the ancient Americas as early as 6000 years ago began planting pepper. But, for the main purpose of pepper is still controversial. Archaeologists think that it purely for seasoning. Mankind began planted peppers very early, and it spread to far away places, the reason is very simple, because it is delicious, people have been realized that chili can prevent food spoilage, extend the function of the storage time. Some pharmaceutical raw materials suppliers thought that the pepper has medicinal value. The experiments show that the pepper extract can inhibit the growth of some microorganisms pathogenic body, capsaicin was also used for local anesthesia.

In the United States, the chili once the novelty of exotic spices, in 1995-2005, the consumption is soared, which reflects that they are a lot of immigrants like to eat spicy food, and also shows that Americans' appetite became more daring. According to the statistics of U.S. Department of Agriculture, each Americans consume 5.9 pounds of pepper every year, the consumption is larger than asparagus, broccoli and green beans.

According to the capsaicin supplier, pepper’s spicy from capsaicin. Capsaicin can stimulate the nerves on the tongue and skin sensor. These nerve sensors are responsible for feelings of temperature rise. View on neurons and brain, your mouth and fired is not much difference. When the temperature rises to a certain extent, it will stimulate the secretion of adrenaline, resulting in rapid heart beat. The scientists said that these reactions is one of the reasons why people fascinated in pepper. Pepper contains a divergent heat substance, capsaicin. The capsaicin can influence the taste buds, nerve cells and nasal mucosa. But what the function does it work in wild chili body is still a mystery until now.

Like other fruit plants, peppers also use a delicious fruit to attract birds and other animals, help spread the seeds. But at the same time, attracted by delicious also have some destruction seed predators, such as rodents will bite and damage the seeds of the fruit, causing it not germinate. Some plants have evolved toxic smell chemicals to drive away seed spoilers, but these chemicals usually prevalent in the roots of plants, leaves and fruit. Capsaicin only exist in the fruit, secreted by a special gland near the stem, with the fruit matures, the more capsaicin secretion.

Bacterial corrosion is the main reason for seeds unfortunately died and failed to offspring. The study found that the lower the degree of capsaicin, the higher the concentration of fungal infection. Fungi is the most active in the humid environment, the more humid the environment, the higher the degree of local capsaicin. In the laboratory, the discovery of the fungus in a spicy pepper easily to control by trace capsaicin, and fungi found in the high degree of spicy chili can withstand a higher concentration of capsaicin.
