Embodiment 1

[0017] A method for resourceful utilization of scallop shells to prepare high-efficiency composite food preservatives is characterized in that it comprises the following steps:

[0018] (1) Scallop shell pretreatment: wash the scallop shell, dry it, crush it through a 40-mesh sieve;

[0019] (2) Secondary high-temperature burning: Burn the pulverized scallop shells at 1100-1500°C for the first time for 15-20 minutes. Stir and dissolve at 50°C until mature, centrifuge the suspension at 5500r / min, dry the resulting precipitate at 100°C to constant weight; then burn at 1100-1500°C for 15-20min, After cooling, grind through a 200-mesh sieve to obtain activated calcium oxide;

[0020] (3) Ultrasonic assisted extraction of Chinese herbal medicine: Weigh the Chinese herbal medicine according to the ratio of 30 parts of Coptidis Rhizome, 15 parts of Scutellaria Baicalensis, 15 parts of Folium Folium, 8 parts of Forsythia, 6 parts of Junchen, and 3 parts of Licorice, shear and mix; th...

Abstract

The invention discloses composite food preservative based on resource comprehensive utilization of waste scallop shells in scallop processing. The preservative has the advantages of being natural, efficient, safe, nontoxic and the like. A preparation method of the preservative comprises the steps of selecting and using the safe scallop shells which has no side effect and Chinese herbal medicine such as coptis chinensis, scutellaria baicalensis, folium isatidis, fructus forsythiae, artemisia scoparia waldst and liquorice, preparing active calcium oxide by burning the scallop shells for a secondary time, conducting ultrasonic-wave-assisted secondary digestion on the Chinese herbal medicine, then integrating the active calcium oxide of the scallop shells which is obtained by burning, Chinese herbal medicine ethanol extracts and mannan, and obtaining the food preservative. According to the method for preparing the efficient and composite food preservative by resource utilization of the scallop shells, active ingredients of the Chinese herbal medicine products are high in leaching rate, the food preservative product is wide in bacteriostasis scope and great in bacteriostasis capability, the food fresh keeping time can be effectively prolonged, requirements of people for the food preservative which is healthy, safe and free of side effect are satisfied, and the resource utilization of the scallop shells is achieved.

Description

technical field [0001] The invention relates to a method for resourcefully utilizing scallop shells to prepare a high-efficiency composite food preservative, belonging to the field of food additives. Background technique [0002] The food processing industry has become one of the three pillar industries of the national economy. Since food is easily damaged by various harmful microorganisms during processing, storage, and consumption, it will deteriorate and spoil, so food preservation and preservation has become an important issue in the food processing industry. With the gradual strengthening of people's living standards and environmental protection awareness, people's requirements for antiseptic preservatives are also getting higher and higher. Food preservation technology has physical, chemical and biological methods. Physical methods include microwave sterilization, high-voltage electric field sterilization, high-pressure low-temperature preservation, electrostatic ste...
