Problems solved by technology

However, heavy metal cadmium exists in varying degrees in Ganoderma lucidum spore powder. Cadmium is highly toxic, and once it enters the human body, it is extremely difficult to excrete. It mainly accumulates in the liver and kidney, causing damage.

Embodiment 1

[0021] The method for reducing the heavy metal cadmium in Ganoderma lucidum spore powder comprises the following steps:

[0022] 1. Adsorption

[0023] Pour 200L of 14% phytic acid solution into a 300L soaking reactor, put in 20Kg of Ganoderma lucidum spore powder raw material at a speed of 40r / min, raise the temperature to 45°C, keep it warm for 2 hours, drop the material to 28°C, and start dehydration and separation.

[0024] 2. Separation

[0025] The centrifuge uses a 300-mesh filter bag to separate the solid from the liquid and reuse the filtrate. The solid Ganoderma lucidum spore powder is washed and then dried, and placed in a stainless steel material tray to enter the drying process.

[0026] 3. Drying

[0027] Use a vacuum drying oven with a vacuum degree of -0.08MPa and a drying temperature of 60°C to dry the Ganoderma lucidum spore powder, and collect the material when the moisture content of the material is ≤8%.

[0028] Table 1 is the comparison before and afte...

Embodiment 2

[0034] The method for reducing the heavy metal cadmium in Ganoderma lucidum spore powder comprises the following steps:

[0035] 1. Adsorption

[0036] Pour 140L of 12% phytic acid solution into a 300L soaking reactor, put in 20Kg of Ganoderma lucidum spore powder raw material at 60r / min, raise the temperature to 45°C, keep it warm for 2 hours, drop the material to 30°C, and start dehydration and separation.

[0037] 2. Separation

[0038] The centrifuge uses a 300-mesh filter bag to separate the solid from the liquid and reuse the filtrate. The solid Ganoderma lucidum spore powder is washed and then dried, and placed in a stainless steel material tray to enter the drying process.

[0039] 3. Drying

[0040] Use a vacuum drying oven with a vacuum degree of -0.08MPa and a drying temperature of 60°C to dry the Ganoderma lucidum spore powder, and collect the material when the moisture content of the material is ≤8%.

[0041] Table 2 is the comparison before and after adsorptio...

Embodiment 3

[0045] The method for reducing the heavy metal cadmium in Ganoderma lucidum spore powder comprises the following steps:

[0046] 1. Adsorption

[0047] Pour 160L of 13% phytic acid solution into a 300L soaking reactor, put in 20Kg of Ganoderma lucidum spore powder raw material at a speed of 60r / min, raise the temperature to 45°C, keep it warm for 2 hours, drop the material to 30°C, and start dehydration and separation.

[0048] 2. Separation

[0049] The centrifuge uses a 300-mesh filter bag to separate the solid from the liquid and reuse the filtrate. The solid Ganoderma lucidum spore powder is washed and then dried, and placed in a stainless steel material tray to enter the drying process.

[0050] 3. Drying

[0051] Use a vacuum drying oven with a vacuum degree of -0.08MPa and a drying temperature of 60°C to dry the Ganoderma lucidum spore powder, and collect the material when the moisture content of the material is ≤8%.

Abstract

The invention discloses a method for reducing heavy metal cadmium in ganoderma lucidum spore powder. The method comprises the following steps of: (1) adding the ganoderma lucidum spore powder into a phytic acid solution under a stirring condition, heating to 45 DEG C for adsorption, and after adsorption is finished, cooling to 28 to 30 DEG C to obtain a material A; and (2) filtering the material A, and drying to obtain the ganoderma lucidum spore powder with low cadmium content. According to the method, the phytic acid solution is used as an adsorbent for adsorbing the heavy metal cadmium in the ganoderma lucidum spore powder, so that the cadmium content in the ganoderma lucidum spore powder can be reduced from 0.4mg / kg to 0.027mg / kg.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for reducing heavy metal cadmium in ganoderma lucidum spore powder. Background technique [0002] Ganoderma lucidum is a traditional fungus treasure in my country and enjoys the reputation of "immortal grass". Ganoderma lucidum, also known as Ganoderma lucidum, fairy grass, also known as red lucidum, red lucidum, wood Ganoderma lucidum, fungus Ganoderma lucidum, Wannian mushroom, Ganoderma lucidum, is the whole plant of red lucidum or purple lucidum of the polyporaceae plant, and is the fruiting body of polyporaceae fungus Ganoderma lucidum. The shape is umbrella-shaped, and the cap is kidney-shaped, semicircular or nearly circular. "Shen Nong's Materia Medica" and "Compendium of Materia Medica" recorded the efficacy and functions of Ganoderma lucidum in detail. Ganoderma lucidum has been officially recorded in the National Pharmacopoeia as a medicine, and it i...
