Problems solved by technology

[0006] Thus, hydrolysis of keratin-containing materials by means of harsh treatments such as heat and chemicals suffers from the problem of incomplete hydrolysis and contamination of food with unfavorable amino acids and residual salts
Additionally, such methods have not been successful in producing highly digestible foods

Embodiment I

[0091] Pretreatment

[0092] Collect 372 kg of freshly processed raw feathers at 36-38°C. During the process of transferring feathers to two 378 liter stainless steel airtight containers or tanks, 0.74 kg of Na dissolved in 8 liters of water 2 S 2 O 5 Spray layer by layer onto the raw feather layer. Each tank is equipped with a perforated plate which is located above the conical bottom part of the tank. High volume low pressure (HVLP) steam at 148-157°C is sprayed into the feather balls, which come from a discharge pipe located at the bottom of each tank. The steam passes through the corresponding perforated plate to spread throughout the feathers. The steaming process lasts for 20-30 minutes until the feather temperature as measured on the top layer reaches 90-93°C. The treated and steam heated feathers were left in the tank during the next 2 hours until other processing steps were performed. At the end of this 2 hour period, the temperature of the feathers on the top of the...

Embodiment II

[0095] Example II Using reducing agent

[0096] Pretreatment

[0097] Collect 372 kg of freshly processed raw feathers at 36-38°C. During the process of transferring feathers to two 378-liter stainless steel airtight containers or tanks, 0.74 kg of Na dissolved in 8 liters of water 2 S 2 O 5 Spray layer by layer onto the raw feather layer. The treated feathers were left in the tank during the next 2 hours, and excess water from the feather settling was allowed to flow out during this time. At the end of the 2 hour period, feather dry matter accounts for 36-40% w / w.

[0098] Enzymatic hydrolysis

[0099] 114 liters of water were heated to 60°C in a reaction vessel having a capacity of 568 liters. 1.5% dry keratinase (w / w total raw feathers) was dissolved in 3 liters of water, and 1% liquid papain (w / w total raw feathers) was added to the container. Next, 372 kg of feather material from the pretreatment step was manually charged into the reaction vessel over a period of 1 hour, whil...

Embodiment III

[0100] Example III uses emulsification

[0101] Pretreatment

[0102] Collect 372 kg of freshly processed raw feathers at 36-38°C. During the process of transferring feathers to two 378 liter stainless steel airtight containers or tanks, 0.74 kg of Na dissolved in 8 liters of water 2 S 2 O 5 Spray layer by layer onto the raw feather layer. Leave the feathers in the tank during the next 2 hours, and allow excess water from the feather settling to flow out during this time. When the 2 hour period is over, the feather dry matter accounts for 36-40% w / w.

[0103] Enzymatic hydrolysis

[0104] 114 liters of water were heated to 60°C in a reaction vessel having a capacity of 568 liters. 1.5% dry keratinase (w / w total raw feathers) was dissolved in 3 liters of water, and 1% liquid papain (w / w total raw feathers) was added to the container. Next, 372 kg of feather material from the pretreatment step was manually charged into the reaction vessel over a period of 1 hour, while being mixed b...

Abstract

The present invention relates generally to a method for enzymatic production of food protein ingredients from keratin-containing proteinaceous materials and the resulting compositions. The process includes treating a proteinaceous containing material with an amount of a reducing agent, followed by hydrolysis of the keratin by a proteolytic enzyme to efficiently and economically convert a keratinaceous protein source into a palatable, highly digestible protein food product.

Description

Technical field [0001] The present invention basically relates to a method for enzymatically preparing food protein components from keratin-containing protein materials and the prepared composition. More specifically, it relates to a method for producing food protein from a source containing keratin by denaturing and pre-treating keratin, and then hydrolyzing the keratin by proteolytic enzymes to efficiently and economically convert the keratin source into a delicious height Digestible protein food. Background of the invention [0002] It is well known that the growth of the world's population will put pressure on food supply and production. As the population increases, already expensive food ingredients, such as food protein, can be extremely expensive for pets and companion animals to consume. Therefore, there is a need for alternative protein sources that do not compete with the human food chain. This alternative protein source includes common animal by-products such as fea...
