Problems solved by technology

Chinese patent CN1923052A discloses a comprehensive utilization technology of Peruvian squid viscera. The method is processed by cooking, enzymatic liquefaction, heating and centrifugation. The supernatant is subjected to saponification, decolorization and deodorization steps to obtain refined squid oil. Protein-rich components, refined squid oil and protein-rich components are used as animal feed additives, this method can make full use of squid viscera, but the process is more complicated and the cost is higher
However, so far, there is no report on the use of squid viscera to produce liquid bio-organic fertilizers at home and abroad.

Embodiment 1

[0045] (1) Beating: collect the offal of squid processing enterprises-squid viscera, weigh them, use a homogenizer to beat the squid viscera and homogenize it within 12 hours, and pour it into the fermentation tank.

[0046] (2) Add water: add water to the fermentation tank, the amount of water added is 2.0L / kg relative to the weight of squid viscera in step (1), and stir evenly.

[0047] (3) Enzymolysis: first control the temperature of the fermentation tank to be about 25°C, add neutral protease, the amount added is 420U / g relative to the weight of squid viscera in step (1), stir evenly, and enzymolysis for 3h; then control the temperature of the fermentation tank The temperature is about 40°C, add neutral lipase in an amount of 880 U / g relative to the weight of the squid viscera in step (1), stir evenly, and continue enzymatic hydrolysis for 5 hours.

[0048] (4) Adding sugar: add 1% glucose relative to the weight of squid viscera in the step (1) in the fermentation tank, a...

Abstract

Provided is a method for producing a liquid biological organic fertilizer by squid viscera, wherein the method includes the following steps: a) beating and homogenizing the squid viscera, and pouringinto a fermentation tank; b) adding water into the fermentation tank, and stirring evenly; c) firstly, controlling the fermentation pool temperature to be 25-30 DEG C, adding neutral protease, stirring evenly, carrying out enzymolysis for 2-3 hours, and then controlling the fermentation pool temperature to be 40-45 DEG C, adding neutral lipase, stirring evenly, and continuing to carry out enzymolysis for 3-5 hours; d) adding sugar with the amount 0.5-1% of the weight of the squid viscera in the step (1) into the fermentation tank, and stirring evenly; e) adding saccharomyces cerevisiae, bacillus subtilis, trichoderma reesei and azotobacter chroococcum into the fermentation tank, and stirring evenly; f) fermenting: carrying out heat preservation fermentation; g) stopping stirring, and standing for 36-48 hours; h) filtering: removing surface floats, taking a supernatant, and filtering with double-layer gauze; and i) preserving the filtrate, and packing.

Description

technical field [0001] The invention relates to a method for producing liquid bio-organic fertilizer by using squid viscera, which belongs to the field of food processing. Background technique [0002] In recent years, the demand for squid at home and abroad has been increasing day by day, and the fishing volume has increased steadily year by year. The inedible part of squid accounts for about 20% of the body weight, of which the internal organs account for about 15%. This part of waste is usually buried for disposal. However, such a treatment method causes waste of resources on the one hand and pollutes the environment on the other hand. According to analysis, squid viscera contains about 70% water, about 13% protein and other components. How to make full use of this part of the material is of great significance for upgrading the squid industry and protecting the environment. [0003] Some people have done research on the use of squid viscera. Chinese patent CN102180945A ...
