The present invention partly relates to albumen complete sex change or partial denaturation of sealing and products thereof.

Hereinafter openly be used to prepare the method for albumen complete sex change or partial denaturation of sealing and products thereof.Interested especially is the application of the lactalbumin sealed, so that it can be incorporated into, for example, and in the corn masa of stone mill or the masa of making by corn flour or the whole corn that boils, to make the snack food of relative high nutritive value.Other application comprises the food with high moisture content, and the wherein said albumen of sealing can be used for producing nourishing food.Not bound by theory, by encapsulating protein, it avoids moist in mixed process, and used water combines in preventing albumen and mixing.

With reference now to Fig. 2,, comprises (for example, using Fitzpatrick DA-6 SS 12 blade beater grinders about 30 seconds) albumen sex change or partial denaturation fully of milling in the first step of this method of the albumen that is used for preparing the lipid packing; Then, albumen that will pulverize and encapsulation agent are combined to form product mixture (for example, the lipid of the albumen of about 80%-about 95% and about 5%-about 20%).The combination of the albumen that will pulverize and encapsulation agent, and heat and stir (for example, about 30 minutes); The temperature of product mixture continues to raise up to the encapsulation agent fusion, and stirs product mixture up to albumen complete encapsulated dose of covering, encapsulating protein thus.The temperature that the fusion encapsulation agent needs depends on encapsulation agent, and usually at about 125 °-Yue 185  (preferably about 125 °-Yue 150 ).At last, the albumen of sealing is being continued cooling (for example, 30 minutes) under the stirring, forming powder (for example, the mobile powder of fundamental freedom) up to its.Encapsulation agent can be any lipid that is suitable for human consumption usually; For example, myristic acid, laurate, palmitic acid, stearic acid, arachidic acid, oleic acid, linoleic acid, leukotrienes (linolcnicacid), arachidonic acid, beeswax, carnuba wax, vitamin A, vitamin D, vitamin E, vitamin K or (for example from coconut, corn, corn oil), olive (for example, olive oil), palm, peanut are (for example, peanut oil) or the lipid (for example, oil) that obtains of safflower.Can use other encapsulation agent except that lipid to realize this effect: the cellulose derivative of broad range, ethyl cellulose, methylcellulose, sodium cellulose glycolate, zein, lac, agar, alginates, dextrin, starch and gelatin; Generally these encapsulation agents are disperseed and be dissolved in the waterborne liquid, and make albumen fluidization in the air-flow of liquid bed coat system of milling, and the spraying of sealing of formation fluid film is sprayed onto on the protein body, and they is wrapped quilt with film forming liquid.

Use planetary gear type to stir bowl, the albumen of complete sex change or partial denaturation is preferably encapsulated in the lipid.When encapsulation agent basically during fusion simultaneously, this allows albumen to be stirred and is coated equably.Other encapsulating method known in the art can be used for realizing this effect, such as fluid bed.When the albumen of sealing cooled off, it was similar to powder in small, broken bits.The albumen of sealing can be preserved, in order to being used as the nourishing additive agent in the food (for example, snacks) with high moisture content preparations in the future.

When the albumen cool to room temperature of BF3, its forms dry solid product.Then, can distribute, and/or join in food (for example, the snacks) mixture at an easy rate with the solid product packing.The solid product of described drying has the physical features of free flowing powder, comprises the particle of diameter in about 25nm (nanometer)-Yue 200nm magnitude range.When using lactalbumin, dry solid product has faint characteristic odor, is similar to the smell of dried milk a little.The complete sex change of sealing that method by preferred embodiment is produced or the albumen of partial denaturation are usually by (for example adding food to, snacks) in the product and send a large amount of nutriment to body, supply with for the obvious nutrient of human body with respect at present available junk food (for example, snacks) formation.

The invention still further relates to the food that is rich in albumen, it comprises albumen or their combination and at least a food composition of the partially or completely sex change mentioned above of sealing (as described herein).Described food composition can be any food composition.For example, food composition can be the composition that is used for biscuit or muffin such as flour.And food composition can be the premix that is used to prepare the stable preservation of packaged of Food ﹠ Drink composition, needs to add other composition (for example, egg, shortening, water or milk) that is provided or added by the producer usually.In addition, food composition can be the mixture (need additionally cook the Foods or drinks product combination food composition that (for example, curing fried, microwave) is easy to eat with formation) that is easy to cook.Usually, food (for example, be rich in albumen) can be any food, such as beverage, sour milk or pizza, or baked product, such as cake, biscuit, custard, cookies, muffin, bread, paddy goods, doughnut, noodles, brownie, crispbread or snacks (snaek food).The amount of the albumen of the partially or completely sex change of sealing that contains in the enriched food can be can influence food sharply any amount (for example, food can contain the albumen of the partially or completely sex change of sealing of the 1%-that has an appointment about 40%, preferably about 5%-about 30%, more preferably about 5%-is about 20%, most preferably about 10%-about 15%).

The albumen of partial denaturation can be used for making expanded or fluffy coated snack product (or particle or semi-finished product) fully; it can fully be cooked or be easy to eat; it (for example also contains at least a food composition; any starch source is such as corn, wheat, paddy rice, barley, rye, potato or their mixture).At present, in the time of in adding dilated product, the product (for example, whey) that contains the lactoprotein of unmodified destroys described matrix and can be not fluffy, and therefore, is necessary to limit to replace about 5% starch with whey.Surprisingly, the albumen of partial denaturation can replace surpassing the starch of 5% (for example, about 5%-about 35%) well, and can not influence fluffy feature, simultaneously, although wherein contain the product of contained high levels lactoprotein, still allow people to obtain desirable crunching and crispness.Usually, the composition that contains the albumen of partial denaturation can replace＞and the starch of about 0%-about 60% is (for example,＞0-60%), preferably＞about 5%-about 60% is (for example,＞5-60%), more preferably about 10%-about 50% is (for example, 10-50%), most preferably about 20%-about 40% (for example, 20-40%).Fully expanded or fluffy coated snack product can contain the 5%-that has an appointment about 80% (for example, the albumen of partial denaturation 5-80%), (for example, 15-60%), more preferably about 20%-about 40% is (for example, 20-40%) for preferably about 15%-about 60%.Expanded or fluffy food (or particle or semi-finished product) can prepare by methods known in the art.For example, the albumen of partial denaturation of the present invention is mixed with corn flour, ratio is the albumen and the 75g corn flour of 25g partial denaturation.With the mixture of the albumen of partial denaturation and corn flour at ZSK30 double-screw extrusion machine (Krupp, Werner ﹠amp; Pfleidercr Company, Ramsey, NJ) interior extruding, described extruder is made up of each 9 thermotank parts controlling separately; Preceding 6 zones are in 35 ° respectively, and 35 °, 50 °, 50 °, 75 " and 90 ℃, and last 3 barrel temperatures are set at 100 ° respectively, 110 ° and 125 ℃.The plug-in unit (3.18mm diameter) of being furnished with 2 circles on the die plate.Melt temperature is recorded on the die.With the constant setting of the 800rpm of the feed rate that produces 128.5g/min, with described mixture be fed to extruder with 6300 series digits, 35 type double helix volume chargers (K-Tron Corp., Pitman, NJ).(MA) speed with 1.3L/h adds entry for Milton Roy, Acton, so that the water content of charging thing is about 18g HiO/100g product (wet basis) to use the electromagnetic quantitative feed pump.The helix speed of extruder remains on 300rpm.Select screw element by in structure, adding kneading piece (kneading blocks), so that the high shear force of 300rpm to be provided.Described method can also be used other albumen, and such as for example, soybean protein, vegetable protein, animal protein and other carbohydrate resource are such as wheat, barley, paddy rice and starch.

Except the above-mentioned method of sealing, the present invention relates to food---and particularly coated snack product---it can be in conjunction with the described albumen of sealing.In a preferred embodiment, the albumen of sealing is used for the method for production table tortillas.The typical prior art method that is used to prepare table tortillas comprises the soaking corn shell; Remove shell from the corn that soaks; The corn of milling and removing the peel; In the corn of milling, add entry to form masa; The described masa of rolling between two rolls is to make the masa sheet of predetermined thickness; Masa in blocks is cut into the shape (normally triangle) that needs; In baking box, cure the masa of triangle; The fried masa that cures; And the last flavoring that needs of using is given fried cake sheet seasoning.

Although some snack foods can be introduced lactalbumin in the process of cooking, many snack foods (comprising table tortillas and cheese curls) can not prepare with the lactalbumin of simple introducing.Reason is that dry albumen has the affinity to water.If the lactalbumin of drying is directly introduced in the masa, it will siphon away the most of water in the masa, destroy masa thus, and prevent that the correct formation of thin slice, described thin slice can be cut into the triangle that forms table tortillas.In addition, albumen is changed in the process of cooking.When albumen was heated, they tended to prepare hard and anti-food of chewing, and produced the mouthfeel that is similar to meat, destroyed the taste and the structure of food thus.By in masa, introducing the amount of pre-determining (for example, about 5%-be'ss about 35%, and preferably about 10%-is about 25%, and more preferably about 15%-is about 20%) the lactalbumin of sealing of the present invention, 2 problems have been solved surprisingly.At first, albumen stuck with paste with moistening powder separate, prevent humidity thus by the wicks masa.Secondly, make albumen avoid heat treated, change into long-chain to prevent albumen; Therefore, the food by this method preparation has kept their initial tastes and structure (especially, they can not become hard and " anti-chewing ").

Other baked goods with high-moisture is the candidate who replaces part dough/pasta/cream batter with the lactalbumin of sealing.Those skilled in the art should be able to adopt the method for this paper and technology to prepare more muffin, cake and the pie of low-carb after reading present disclosure.

Another object of the present invention is to produce the lactalbumin wrap into lipid, unites with suitable exercise and metatrophia and is used to reduce body fat.

Another object of the present invention is to produce the lactalbumin wrap into lipid, and it causes the train on that improves.

Another object of the present invention be produce will with the lactalbumin of sealing of carbohydrate combination, be used in the catabolism patient's condition clinical and/or the situation treatment patient of hospital.

Another object of the present invention is that protein groups is made up of following: lactalbumin isolate, whey protein concentrate, whey peptides, whey dipeptide, whey oligopeptide, whey polypeptide, soybean protein (comprising dipeptides, polypeptide and oligopeptides), casein and ovalbumin from any of albumen or albumen that combinations produce is lipid encapsulated.

Because the albumen of sex change is non-absorbent fully, so when it contained the albumen of complete sex change, food was a kind of diet fiber composition.

Following example just is intended to further illustrate the present invention, is not to be intended to limit the present invention by the defined scope of claim.
