Abstract
The invention relates to a composition capable of reducing the lead content of tea oil, which comprises 45-60 mg of iron dextran sheets and 32-48 ml of calcium gluconate. According to the invention, on the basis of not changing the original oil tea processing step, the composition is added in the filtering step of oil tea processing, so that the lead content in the oil tea can be effectively reduced, a tea oil sample subjected to lead reduction treatment by the composition is sent to a product quality inspection institute for detection, and the lead content is about 0.05 shown by the inspection result and completely reaches the standard. The method solves the problem of overhigh lead content of the tea oil caused by the over standard lead content in the land in the planting areas with high lead content, such as the province of Hunan province, breaks through the traditional method of the over standard lead content of the existing standard oil, saves time and labor, greatly saves the production cost of tea oil processing, and effectively promotes the development of the native oil tea industry.
Description
Technical Field
The invention relates to the field of tea oil production, in particular to a composition capable of reducing the lead content of tea oil.
Background
The tea oil is a unique camellia woody edible oil in the south of China and is one of four woody plant oils in the world. The tea oil is a real pure natural organic edible oil because of being rich in omega-3 fatty acid, omega-6 fatty acid and containing a small amount of tea saponin and tea polyphenol, does not contain cholesterol, erucic acid and cornic acid, has no pesticide residue, has the name of oriental olive oil, has the physical and chemical properties similar to olive oil, has good stability and oxidation resistance, long shelf life, high smoke point, high temperature resistance and easy digestion and absorption by human bodies, and is classified as the key health edible oil for popularization by the international food and agricultural organization.
The province of Hunan province is one of the important production areas of tea oil, but the high heavy metal content of the land in the province of Hunan province is a commonly recognized problem, the most important of which is lead. Lead is easy to cause poisoning, and can cause face yellowing, anemia and constipation of unknown reasons, even dysfunction of nervous system, sweet taste in mouth, hypodynamia and eyeground bleeding, and dysplasia if lead poisoning occurs to children, and intestinal colic, anemia and muscular atrophy can occur to severe people until paralysis is removed, the children have disabilities for life, and even die. It is known that the lead content of the tea oil which is produced by the locally planted tea-oil tree and is not subjected to lead reduction treatment reaches about 2.07 by inspection, and exceeds the national regulation, so that the planting, processing and sale of the local tea oil are seriously influenced. The current common lead-reducing method is mixing, namely, products with qualified quality are used, and products with standard exceeding are diluted. That is to say, the product exceeding the standard is many times, and the effect can be achieved only by using several times of qualified product, so that time and labor are wasted, the production cost of local tea oil is increased, and the development of the tea oil industry is restricted.
Disclosure of Invention
The object of the present invention is to improve and innovate the disadvantages and problems of the background art and to provide a composition which can reduce the lead content of tea oil.
The composition of the invention comprises 45-60 mg of iron dextran tablets and 32-48 ml of calcium gluconate.
Preferably, the composition comprises 48 to 55 mg of iron dextran tablets and 38 to 45 ml of calcium gluconate.
Preferably, the calcium gluconate is calcium gluconate containing 10% of sugar.
The composition of the invention is added in an amount of 300 kg of raw tea oil, and is added in the filtering step of tea oil processing.
The invention has the advantages and beneficial effects that:
according to the invention, on the basis of not changing the original oil tea processing step, the composition is added in the filtering step of oil tea processing, so that the lead content in the oil tea can be effectively reduced, a tea oil sample subjected to lead reduction treatment by the composition is sent to a product quality inspection institute for detection, and the lead content is about 0.05 shown by the inspection result and completely reaches the standard. The method solves the problem of overhigh lead content of the tea oil caused by the over standard lead content in the land in the planting areas with high lead content, such as the province of Hunan province, breaks through the traditional method of the over standard lead content of the existing standard oil, saves time and labor, greatly saves the production cost of tea oil processing, and effectively promotes the development of the native oil tea industry.
