Benefits of technology

The present invention relates to an albumen decomposed product that has better taste and is easier to use as an ingredient in food, beverages, feed, and other products. It has emulsifying properties, is safe for use, and can help produce non-fat or low-fat, low-cholesterol, and high-protein emulsified foods. The invention also includes an emulsfier that is safe, effective, and can be used alone or together with other emulsifiers.

Problems solved by technology

However, when albumen proteins are denatured so that the localization of hydrophilic and hydrophobic amino acids in their molecule is disrupted, emulsifiability can be developed.
Therefore, the improvement in emulsifying capacity cannot be expected.
Besides, the emulsion stability is bad.
In addition to such features of albumen, as for processed egg, yolk is in great demand and used in mayonnaise and western confectioneries, and the consumption thereof tends to increase.
Whereas, the consumption of albumen decreases along with weak demand of fish paste products, and a large amount of surplus albumen is now frozen for storage.
The frozen storage cost imposes great burden on chicken egg processors, and new use development of albumen is demanded.

Preparation of Albumen Hydrolysate (Study on Hydrolysis Degree)

[0094]Products (500 g each) prepared by adding a 10% citric acid solution (24 ml) to 3 L of an albumen liquid (pH 9.0) and adjusting the pH of the mixture to pH 7.5 were warmed to 55° C., and a heat resistant proteolytic enzyme (Thermoase PC10F: 90,000 units / g, Amano Enzyme Inc.) was added thereto in an amount of 0.1%, 0.2%, 0.4% and 0.8%, respectively. The resultant mixtures were enzymatically decomposed while being stirred at 55° C. for 10 minutes. Then, the albumen liquids were subjected to temperature increase to 65° C., and enzymatically decomposed while being stirred for further 30 minutes. Thereafter, the albumen liquid was immediately subjected to temperature increase to 90° C., and held for 10 minutes for enzyme deactivation. The albumen hydrolysates after the enzyme deactivation were stirred to be homogenized, thereby preparing albumen hydrolysate samples 1 to 4. Incidentally, an albumen liquid was similarly ma...

Mass Preparation 1 of Albumen Hydrolysate

[0102]One hundred (100) Kg of an albumen liquid (pH 7.8) was warmed by a warm water circulation jacket tank (200-L-volume), and 200 g of Thermoase PC10 was added thereto and dissolved therein at 55° C. The liquid was stirred for 10 minutes. Then, the liquid temperature was increased to 65±2° C., and the liquid was stirred for 30 minutes. Thereafter, the liquid temperature was held at 95±2° C. for 5 minutes, and enzyme deactivation was carried out also for heat sterilization. Then, the protease-treated hydrolyzed albumen was stirred to be homogenized with a homomixer, thereby preparing 97.2 Kg of an albumen hydrolysate (Sample 6).

Mass Preparation 2 of Albumen Hydrolysate

[0103]Using a warm water circulation jacket tank (200-L-volume) as a balance tank, 200 Kg of an albumen liquid (pH 8.5) was circulated to a shell & tube type heat exchanger, STD model (Iwai Kikai Kogyo Co., Ltd.) at a flow rate of 150 Kg / h, and, when the temperature of the liquid within the balance tank reached 55° C., 200 g of Thermoase PC10 was added and dissolved. The temperature was retained at 55±2° C., and the liquid was circulated for 10 minutes. Then, the liquid temperature was rapidly increased to 65° C., and retained at 65±2° C., and the liquid was circulated for 30 minutes. Finally, the liquid temperature was retained at 95±2° C. for 5 minutes, and enzyme deactivation was carried out also for heat sterilization. Then, the liquid was rapidly cooled, thereby preparing193 Kg of an albumen hydrolysate (Sample 7).

Abstract

The present invention addresses the problem of providing an albumen hydrolysate that has emulsifiability, emulsion stability and heat coagulability. An albumen hydrolysate obtained by hydrolysis of albumen with a protease, wherein the dry weight of a precipitate formed by adding nine times the amount of 0.4 M trichloroacetic acid (TCA) to the albumen hydrolysate is 60% or more relative to the dry weight of albumen treated in the same manner.

Description

TECHNICAL FIELD[0001]The present invention relates to an albumen hydrolysate having high emulsifiability, emulsion stability and heat coagulability and a process for producing the same. Also, the invention relates to an emulsifier and an emulsion stabilizer comprising the albumen hydrolysate, and various processed foods.BACKGROUND ART[0002]Chicken egg has traditionally been utilized as a food and a food material (processed egg). Humankind has developed a number of egg dishes and egg-utilized foods and made use of egg at rich dietary life. This is because egg has excellent nutritional property and has various functional properties suitable for cooking and food processing.[0003]The main functional properties of processed egg utilized in the field of foods include the heat coagulability and foaming property of albumen and the emulsifiability of yolk. The addition of physical manipulations such as heating, foaming and emulsification to egg causes a structural change in its albumen prote...
