Embodiment 1

[0041] 1) Purchase 50 kg of tilapia leftovers from tilapia fillets produced by the tilapia manufacturer, remove the viscera, blood stains and other inedible parts of the raw fish at an ambient temperature of 10°C, and wash them with 0°C ice water 2 times;

[0042] 2) Under the ambient temperature of 5-10°C, chop the raw materials into 3-4cm and 1-2cm wide pieces of broken fish bones;

[0043]3) Rinse the broken fish bones in dilute saline water for 3 times and drain the water. The mass ratio of the broken fish bones to dilute saline water is 1:4;

[0044] 4) At an ambient temperature of 5-10°C, use a wet-process ultrafine pulverizer to pulverize the fishbone pieces rinsed in the above step 3) into fishbone pulp, and the pulverization fineness is 60 mesh;

[0045] 5) Adjust the pH value of the fish bone pulp to 4.5 with a 5% lactic acid solution by mass fraction; at the same time, adjust the water mass content in the fish bone pulp to 85% by adding water;

[0046] 6) Divide t...

Embodiment 2

[0052] 1. Purchase 50 kg of red drum fish fillets left over from red drum fish fillets produced by the red drum fish manufacturer. Remove the viscera, blood stains and other inedible parts of the raw fish at an ambient temperature of 10°C and wash them with 0°C ice water. 2 times;

[0053] 2. Under the ambient temperature of 5-10°C, chop the raw materials into 3-4cm and 1-2cm wide pieces of broken fish bones;

Abstract

Belonging to the field of food deep processing, the invention discloses a method for production of high active calcium fishbone pulp by ultra-high pressure micro-jet technology and prepared fishbone pulp. The method includes the steps of: raw material cleaning, raw material chopping, raw material rinsing, fishbone pulp production, adjustment of pH and moisture content of the fishbone pulp, ultra-high pressure micro-jet homogenization, strain adding, and fishbone pulp fermentation, thus obtaining the high active calcium fishbone pulp. Before fermentation, ultra-high pressure micro-jet homogenization pretreatment is carried out on the fishbone pulp, thus being conducive to loosening the internal tissue structure of fishbone pulp and softening calcium carbonate, calcium hydroxylapatite crystals and other water-insoluble substances, facilitating the transformation of inorganic calcium crystals by probiotics and related enzymes, and increasing the content ratio of calcium ions in fishbone pulp.

Description

technical field [0001] The invention belongs to the field of food deep processing, and in particular relates to a method for producing high-activity calcium fish bone pulp by using ultra-high pressure micro-jet technology and the prepared fish bone pulp. Background technique [0002] At present, small miscellaneous fish and fish scraps in the aquatic industry are mainly used to produce fishmeal or discarded as waste, resulting in low comprehensive utilization of resources and serious environmental pollution. In fact, small miscellaneous fish and fish scraps are rich in calcium and collagen and many other nutrients and active ingredients that are beneficial to the human body. According to the statistics of the World Health Organization, there are currently more than 150 million calcium-deficient people in my country, of which more than 50 million people have obvious symptoms. Calcium supplementation through diet is a simple and effective solution. Although small miscellaneou...
