Embodiment 1

[0018] Example 1: Wash the heads and shells of Procambarus clarkii, dry them in an electric blast drying oven at 45°C for 30 hours, crush them with a high-speed traditional Chinese medicine grinder, pass through a 60-mesh sieve, and store them at -18°C to make shrimps powder; the mass percentage concentration is 22% citric acid solution and the mass percentage concentration is 28% malic acid solution according to the volume ratio equal to 1:1.5 to prepare mixed acid, shrimp powder (g): mixed acid (mL): distilled water (mL) = 1:3.2:54 ratio mixing, leaching; ultrasonic assisted extraction: under the conditions of ultrasonic power 250W, ultrasonic temperature 55 ℃, ultrasonic treatment was performed on the extract for 55min, and finally filtered, and the filtrate was vacuum-dried. That is calcium fruit acid powder. In this example, the extraction rate of calcium ions was 94.85%, the calcium content of the obtained calcium fruit acid powder was 20.84%, and the solubility was 0.80...

Embodiment 2

[0019] Example 2: Wash the heads and shells of Procambarus clarkii, dry them in an electric blast drying oven at 50°C for 28 hours, pulverize them with a high-speed traditional Chinese medicine grinder, pass through a 60-mesh sieve, and store them at -18°C to make shrimp powder It is that 20% citric acid solution and 30% malic acid solution are formulated into mixed acid by volume ratio equal to 1:2 by mass percentage concentration, and shrimp powder (g): mixed acid (mL): distilled water ( mL) = 1:3:50 ratio mixing, leaching; ultrasonic assisted extraction: under the conditions of ultrasonic power 200W, ultrasonic temperature 50 ℃, ultrasonic treatment of leaching solution for 60min, and finally filtration, the filtrate was vacuum dried, that is Get calcium fruit acid powder. In this example, the extraction rate of calcium ions was 95.12%, the calcium content of the obtained calcium fruit acid powder was 20.86%, and the solubility was 0.8215g / 100mL.

Abstract

The invention relates to a method for preparing calcium citrate malate from heads and shells of procambarus clarkii. The method comprises the steps of preparing shrimp meal: cleaning the heads and shells of procambarus clarkii, drying the heads and shells of procambarus clarkii for 25-30 hours at the temperature of 45-55 DEG C, crushing, and sieving by using a sieve with the pore size of 60 meshes so as to prepare the shrimp meal; carrying out acid leaching: preparing mixed acid from a citric acid solution with the mass percentage concentration of 20-22% and a malic acid solution with the mass percentage concentration of 28-32% in the volume ratio of 1: (1.5-2), mixing shrimp meal (g), mixed acid (mL) and distilled water (mL) according to the ratio of 1: (3-3.5): (50-55), and leaching; and finally, carrying out ultrasonic wave assisted extraction, and carrying out vacuum drying, thereby obtaining calcium citrate malate powder. According to the method, the waste of shrimp meat processing can be utilized sufficiently during calcium citrate malate preparation, so that the preparation cost is low, and the source of raw materials is wide; the pollution to the environment caused by strong acid decalcification is avoided effectively; and the prepared calcium citrate malate has moderate calcium content and relatively high solubility.

Description

technical field [0001] The invention relates to a calcium nutrition enhancer-calcium fruitate, in particular to a method for preparing calcium fruitate by using the head and shell of Procambarus clarkii as raw materials. Background technique [0002] Calcium is the most abundant mineral element in the human body and plays an extremely important role in the growth and development of the body. The human body cannot synthesize minerals by itself, and is completely dependent on external supplements and supplies. Sufficient calcium intake plays an important role in the human body's life. If the human body is in a state of calcium deficiency for a long time, it will lead to the induction of various diseases, such as rickets, which is the main symptom of calcium deficiency in children; calcium deficiency in adults causes bone calcium to decrease, and calcium content in blood and cells increases, leading to premature aging; calcium deficiency in pregnant women It can cause pregnanc...
