Things are rare and precious, although truffle is a kind of mushroom species, but the nutritional value contained in it is very high. The requirements of the growth environment of the truffle are very strict, most of them are natural growth, it is difficult to survive if they are artificially cultivated, plus the flavor and taste of the truffle is very good, so in terms of price, naturally, ordinary mushrooms can not be compared.
I, truffles own peculiar flavorThe truffle itself carries a peculiar flavor, high recognition, in the cooking process, through the mix of ingredients, can make the truffle's taste become better, while the truffle contains a wealth of proteins and amino acids, the nutritive value is very high, not only can regulate the endocrine system, but also to prevent Alzheimer's disease as well as anti-tumor.
Second, the harsh growth environmentThe truffle on its own growth environment is very demanding, artificial basically can not be cultivated, the yield is also very rare, which led to the price of truffles expensive. Moreover, truffles will absorb all the nutrients around them during the growth process, so it is generally difficult to grow other plants in the area where truffles grow.
If an area has too many truffles, it will lead to an ecological imbalance, the land and plant nutrients will be absorbed by the truffle, and will make the area in a long period of time can not grow other plants.
Three, dependent on tree growthThe truffle is generally preferred to grow in the pine, oak and willow and other species of trees under the growth, because of the different species of trees, the truffle color and smell will be different. Although truffles are very demanding of the growing environment, they are now grown semi-artificially in a few western countries.
However, because of the increase in human activities, resulting in contaminated soil, as well as excess or reduced rainfall and other reasons, which led to the production of truffles is much less, therefore, the price of truffles has become more expensive.
four, truffle varietiesAmong all the truffle varieties, the black truffle from France and the white truffle from Italy are the most expensive and the most highly rated. Truffles used to be peeled when consumed, but with the scarcity of truffle production, they are now ground to prevent waste.
