Embodiment
[0022] like figure 1 In the shown embodiment, a kind of method that extracts carnosine from bonito head, carries out as follows:
[0023] Step 1. Water extraction: mash the bonito head with a high-speed tissue masher, add distilled water according to the ratio of material to liquid 1:3, stir evenly, adjust the pH value to 5.0, and use an ultrasonic cleaner for auxiliary extraction. Ultrasonic auxiliary conditions: Power 300w, temperature 80°C, ultrasonic time 30 min, continue after the end of ultrasonic assistance, keep stirring at 80°C, rotate speed 100 r / min, leaching for 30 min, filter and collect the extract; the high-speed tissue masher is operated by a cam 1 and the motor connected to the axis of the cam 1 as the drive, the radial end of the cam 1 is provided with a protrusion 2, and the other end is provided with a funnel-shaped depression 12, the interior of the depression 12 is a curved surface, and the depression 12 is connected with the ring surface of the side of t...

Abstract
The invention discloses a method for extracting carnosine from a skipjack head. The method comprises the following steps: crushing a skipjack head by a high-speed tissue pounding machine, adding distilled water according to a material-to-liquid ratio of 1:3, and carrying out desalting, ultrafiltration, drying and the like. According to the method, carnosine is extracted from the skipjack head, sothat environmental pollution caused by chemical synthesis and high cost caused by complicated synthesis steps are avoided. The high-speed tissue pounding machine fully crushes the skipjack head bone,and subsequent extraction operation is facilitated.
Description
technical field [0001] The invention relates to a method for carnosine, in particular to a method for extracting carnosine from bonito head. Background technique [0002] Bonito, commonly known as bomb fish, belongs to Osteophyta, Perciformes, Tuna suborder, Tunaidae, and Bonito genus. It is a migratory fish that lives in tropical and temperate seas, mainly distributed in the Indian Ocean, Pacific Ocean and Atlantic Ocean. Waters where the water temperature is above 15°C. Bonito is red in color, tender in texture, rich in nutrition, rich in high-quality protein, and is a healthy delicacy. During the processing of skipjack tuna, leftovers such as viscera, fish bones, and fish heads, which account for about 60% of the total weight, will be produced, mainly fish heads. If it cannot be used effectively, it will not only cause environmental pollution, but also lead to waste of resources. [0003] Carnosine is a histidine dipeptide that naturally exists in mammals, birds, fish ...
