Detan Frozen Shanghai Black Truffle Mushroom

The black truffle (Tuber melanosporum in Latin and Perigord truffle in English), also known as truffle, is a kind of wild eating fungus that grows underground and has a rugged appearance.

Between dark brown and black color, a small bump, throughout gray or light black and white texture, its special smell, it is difficult to describe, someone like mushroom/garlic/leaf/wetland/fermented corn/pickled kimchi/honey/gas/wet straw/cheese/cinnamon/elk, and as for did not wash the sheets, it has even been described its smells like semen, A few areas, mainly in the Alps and Himalayas, and the Panxi region around Yanbian County in Panzhihua City, Sichuan Province, account for 60% of China's total black truffle production.

Truffles are very fussy about the environment they grow in. They can't grow as long as the sun, water or the pH of the soil change slightly. They are the only delicacy in the world that can't be grown in order. People don't know why truffles grow under one tree and another that looks identical next to it doesn't.

Unlike mushrooms and other fungi, truffle spores are not carried by the wind, but by animals that eat the truffle. Truffles grow mainly under pine, oak, hazel, beech and orange trees because they cannot photosynthesize and survive on their own, and must rely on symbiotic relationships with certain roots for their nutrients.

Modern scientific research data show that black truffles are rich in protein, 18 kinds of amino acids (including 8 kinds of essential amino acids that can not be synthesized by human body), unsaturated fatty acids, a variety of vitamins, zinc, manganese, iron, calcium, phosphorus, selenium and other essential trace elements. And sphingolipids, cerebral glycosides, amide, triterpenes, male ketone, adenosine, truffle acid, sterol, truffle polysaccharide, truffle polypeptide and a large number of metabolites, with high nutritional and health value.

Among them, male ketone can help Yang and regulate the significant effect of endocrine; Sphingolipids have significant activities in preventing senile dementia, atherosclerosis and anti-tumor cytotoxicity. Polysaccharides, peptides, triterpenes have the functions of enhancing immunity, anti-aging, anti-fatigue and so on, which can be used for health care and health.

The Detan factory uses special freezing technology to snap freeze black truffles in a short time at a low temperature of -70 ~ -80 ℃. It can effectively inhibit the damage of black truffle cells in the freezing process. This prevents the truffle from losing its freshness and nutrients. At the same time, the nutrient content of black truffle after thawing was not significantly reduced, and the quality of black truffle after thawing was not significantly different from that before freezing.
