Method for preparing plant carbon black substitute by using leaves of Vaccinium plants as raw material
A plant carbon black and substitute technology, applied in the direction of fermentation, etc., can solve the problems of limiting the use of black rice leaf melanin and the inability to industrialize melanin, so as to speed up the formation of melanin, eliminate the production of benzopyrene, and widely distribute Effect

Embodiment 1
[0025] Take 1Kg of fresh leaves of the black rice tree collected in April, add 2L of deionized water, and mash it with a tissue masher, preventing the local temperature from exceeding 42°C during the mashing process. Transfer to a 10L three-necked flask with a water bath at about 37°C. Pump a certain amount of air flow while stirring. After 3 hours, filter to remove the residue leaves. The resulting filtrate is about 2.2L. Transfer it to a common pressure cooker with a suitable capacity. Kg passes through the rice flour of 300 mesh sieves, fully stirs until the surface of rice flour is completely blackened, begins to be heated to 120 ℃, evaporates moisture. After the rice flour is fully cooked, cool it to room temperature and crush it to 200-300 meshes to obtain a plant carbon black substitute, which is black and bright in color, shiny, good fluidity, almost insoluble in water, and has basically the same physical properties as plant carbon black. In this example, the melanin o...

[0027] Take 1Kg of fresh blueberry leaves collected in May, add 2L of deionized water, and mash it with a tissue masher, preventing the local temperature from exceeding 42°C during the mashing process. Transfer to a 10L reaction kettle with a water bath at about 37°C. Pump a certain amount of air flow while stirring. After 3 hours, filter to remove the slag leaves. The obtained filtrate is about 2.2L. Kg of commercially available wheat flour after passing through a 200-300 mesh sieve, fully stirred until the surface of the wheat flour is completely blackened, and then heated to 120°C to evaporate the water to dryness. After the wheat flour is well-cooked, cool it to room temperature and crush it to 200-300 meshes to obtain a plant carbon black substitute, which is black and bright in color, shiny, good fluidity, almost insoluble in water, and has basically the same physical properties as plant carbon black. In this example, the melanin obtained from 1 kg of fresh leaves throug...
Embodiment 3
[0029]The embodiment that uses plant carbon black and plant carbon black substitute to make chocolate biscuit respectively. Take two parts of 500g flour, add 20g of plant carbon black to one part, add 20g of plant carbon black substitute to the other part, add other ingredients with the same formula, and make two parts of chocolate biscuits after a specific process. A sensory evaluation was conducted by an evaluation group of 14 people. Each person randomly tasted two kinds of chocolate biscuits according to the sensory evaluation procedure, and then scored according to the sensory similarity. Among them, 100 points were completely consistent, and 80 points were basically consistent. The taste was the same but the appearance was different. Larger and the same appearance but with a large difference in taste are scored as 50 points, and 0 points are scored as very different, and the middle score is acceptable. The evaluation results are: 100 points: 3 points; 90-99 points: 7 poin...
