Problems solved by technology

But although this method has the characteristics of high crushing efficiency, low cost, and easy operation, the bone powder made by it has a relatively large particle size and a relatively complete particle surface, while the smaller the particle size of the bone calcium powder, the lower its porosity and surface area. The larger the size, the better the surface adsorption, solubility and dispersibility; and the higher the integrity of the surface of bone meal particles, the worse its solubility and dispersibility, resulting in the widespread presence of particles in bone powder prepared by traditional bone powder preparation methods. The problem of large diameter and low utilization rate cannot meet the needs of users
In addition, there is currently no special preparation process for tuna bone meal on the market, which will further reduce the utilization rate and use effect of tuna bone meal prepared by conventional processes
Therefore, the tuna bone meal made by the existing crushing method has the problems of low utilization rate and poor use effect

experiment example 1

[0032] Experimental Example 1: Using the single-factor rotation method, with product quality (A), microwave power (B) and microwave time (C) as the investigation factors, tuna bones with masses of 60g, 80g, 100g, 120g and 140g were selected as samples in turn , and set the microwave power to 400W, 600W, 800W, 1000W and 1200W respectively, and the microwave heating time to be 30 minutes, 60 minutes, 90 minutes, 120 minutes and 150 minutes, a total of 17 groups of tuna bone experimental groups; then according to the present invention The 17 groups of tuna bone experimental groups were pulverized by the pulverizing method; the particle size of the tuna bone meal obtained after pulverization was measured by a laser particle size distribution analyzer, and the measurement results were shown in Table 1, and the response value was the particle size of the fish bone meal:

experiment example 2

[0036] Experimental example 2: two experimental examples of common fishbone meal group and microwave fishbone meal group are respectively set, wherein common fishbone meal group is pulverized according to the preparation method of the present invention, and the microwave method in step 4. is changed to direct drying treatment, The ordinary fishbone meal sample was obtained; while the microwave fishbone meal group was pulverized according to the preparation method of the present invention, and the microwave parameters were microwave power 800W and microwave time 90 minutes to obtain the microwave fishbone meal sample. Then, the particle sizes of the two groups of fish bone meal samples were observed by scanning electron microscope.

[0037] Observations such as figure 1 As shown (the left curve in the figure is the particle size distribution diagram of microwave fishbone meal, and the right curve is the particle size distribution diagram of ordinary fishbone meal), the average ...

experiment example 3

[0038]Experimental Example 3: The two fish bone meal samples prepared in Experimental Example 2 were evenly spread on the insulating glue fixed on the aluminum sample table, and gold was sprayed with an ion sputtering instrument in a vacuum state to make the surface charged. Scanning electron microscope (SEM) was used to observe the surface morphology of fish bone powder under the condition of accelerating voltage of 10kV.

[0039] Observation results such as figure 2 and image 3 as shown ( figure 2 is the surface structure diagram of common tuna bone meal, image 3 is the surface structure diagram of microwave tuna bone meal), the surface and overall shape of ordinary tuna bone meal are relatively complete, only part of the surface is cracked, the overall shape of microwave tuna bone meal no longer maintains integrity, and micropores appear on the surface of fish bone meal. Therefore, the microwave-assisted crushing process used in the present invention can effectively ...

Abstract

The invention discloses a microwave-assisted preparation process of tuna bone meal. The preparation process comprises the following steps: mixing every 120 g of tuna bone and distilled water in a material-to-liquid ratio of 1:1 to obtain a mixed solution a1, adding trypsin and neutral protease to the mixed solution a1 for enzymolysis, boiling the tuna bone to inactivate enzyme, and performing microwave heating treatment at a microwave power of 400-1200 W for 30-150 minutes; finally, grinding the tuna bone by a grinder to obtain the finished bone meal. The preparation process can effectively increase the utilization rate and use effect of the tuna bone meal.

Description

technical field [0001] The invention relates to a preparation process of fish bone meal, in particular to a microwave-assisted preparation process of tuna bone meal. Background technique [0002] Due to its high nutrition and high edible value, tuna is generally processed into tuna sashimi and canned fish, which is loved by consumers all over the world; but tuna bone is one of the by-products of the tuna processing industry, because of its economic benefits Lows are usually discarded along with other by-products like guts. However, since the calcium content in tuna bone is very rich, and the ratio of calcium and phosphorus in fish bone meets the needs of human body, tuna bone can be processed into available fish bone meal feed or calcium supplement, which can greatly improve the utilization of tuna. rate and generate greater economic benefits. [0003] At present, the preparation method of bone meal is mainly mechanical crushing method. However, although this method has t...
