Problems solved by technology

However, the production method of this patent publication is more complicated than the Taiwan Publication No. I263678 Invention Patent Case, which makes the production cost of collagen relatively increased. Following the increase in production costs, the price will rise, but it will make consumers timid and hinder the promotion of the economic market size of edible collagen

Embodiment Construction

[0029] The present invention will be described in detail below with reference to the drawings and embodiments. Before the present invention is described in detail, it should be noted that in the following description, similar steps are represented by the same numbers.

[0030] Refer to figure 1 The first preferred embodiment of the fish scale processing method of the present invention includes a pretreatment step 21, a pressure increase step 22, a braising step 23, a filtration step 24 and a standing step 25.

[0031] The pretreatment step 21 is to clean 2.5 kg of raw fish scales, prepare 5 kg of boiling water, put the raw fish scales in boiling water and boil for 20 minutes to obtain a mixed solution. In this step, the raw fish scales are softened. In order to facilitate the subsequent hydrolysis, the source of the fish scale raw materials is not limited to any fish species, such as sea bream, Wu Guo fish, Taiwan sea bream, milkfish, etc. As long as the source supply is stable, th...

Abstract

The invention discloses a fish scale processing method, which comprises the following steps of: washing fish scale raw materials and putting the fish scale raw materials into boiled water to obtain mixed liquid; transferring the mixed liquid to a sealed reaction container, heating the reaction container to improve the pressure inside and increase the temperature of the mixed liquid to hydrolyze the mixed liquid; then simmering the mixed liquid in the reaction container and relieving the pressure in the reaction container at a set time to obtain solution containing collagen; and later on, filtering the solution to separate a solid substance and collagen solution. Heating to pressurize and continuously simmering the fish scale raw materials in this way to fast hydrolyze the fish scale raw materials so as to obtain a large amount of food-grade collagen from the fish scale within a short time, speed up the manufacturing speed of the product and save the production cost.

Description

Technical field [0001] The invention relates to a fish scale processing method, in particular to a processing method for obtaining collagen from fish scales to prepare collagen food. Background technique [0002] Most of the existing methods of obtaining collagen come from mammals such as cows, pigs, chickens, or poultry animals, etc., which belong to animal collagen. However, due to the increase in animal epidemics in recent years, mad cow disease in cattle, foot-and-mouth disease in pigs, and avian influenza in chickens have all made consumers feel uneasy about food, and related processed foods of cattle, pigs and chickens have also been affected. Therefore, there are doubts about the safety of collagen produced from cattle, pigs, chickens and other animals. [0003] As a result, related companies began to use fish scales with low pollution and high safety as a source of collagen production. According to the invention patent of Taiwan Announcement No. I263678, “Fish Scale Colla...
