Processing method of nano herringbone meal

Abstract

The invention discloses a processing method of nano herringbone meal. The processing method is characterized by comprising the following steps of: (1) laying cleaned herringbones on a large disc and baking at 170-220 DEG C for 2.5-4 hours, wherein the herringbones is overturned once in the baking process, so that both sides of each herringbone can be fried in fish oil by not less than 1 hour; (2) crushing herringbones to 0.8-1 centimeter with a mechanical method; (3) putting herringbone coarse meal into a hydrochloric acid solution of which the volume is 10 times that of the herringbone coarse meal and the pH is 6 and which is heated to 75-85 DEG C, stirring for 5-10 minutes, draining and drying at 160 DEG C for 4 hours; or adding herringbone coarse meal into petroleum ether of which the volume is 5 times that of the herringbone coarse meal, leaching for 40 minutes, draining the petroleum ether and drying at 60 DEG C for 1 hour; and (4) milling with a ball or a stick for 6-8 hours to obtain nano herringbone meal of which the particle size distribution peak value is 130-220 nanometers, wherein the medium filling rate is 30-40 percent, and the rotating speed is 800-1,000rmp. According to the processing method, fish processing leftovers are effectively utilized; and the nano herringbone meal can be used for enriching nutrients such as proteins, calcium and the like of natural foods, and can be directly taken as a snack food or enriched food together with auxiliary materials.

Description

technical field [0001] The invention belongs to the field of food processing science and can be widely used in various food processing including fish processing, especially the processing of leftovers of traditional fish products, as well as protein and calcium supplements. Background technique [0002] Fish is rich in nutrients, and every 100 g of fish meat contains 13g of protein, 4g of fat, 39mg of calcium, 143mg of phosphorus, and 0.9mg of iron. Fish meat can be processed into various foods, ranging from fresh fish, canned fish to casual snacks. However, in fish processing, usually only the meat pieces on both sides of the fish body are used and the fish bones and the part of fish meat attached thereto are discarded, resulting in a large waste. Fish bones are also rich in nutrients. The calcium content is about 17%, the phosphorus content is about 8%, and the protein content is more than 30%. For example, in the processing of tilapia, catfish, channel fish, etc., the l...

Problems solved by technology

For example, in the processing of tilapia, catfish, channel fish, etc., the leftovers produced after removing the two sides of the meat, that is, the fish spine, including the fish backbone skeleton and part of the fish attached to it, can only be used as waste Abandoned, or sold at a very low price to make feed or even fertilizer, seriously affecting the utilization of fish resources
