Patients with chronic diseases such as kidney disease and cancer need nutrients, especially protein, to repair and restore the body. The amount of protein that should be intake is quite close to normal people, which is between 0.6-0.8 grams per kilogram of body weight per day. For example, a 50 kg patient should receive 30-40 grams of protein per day. For kidney patients after dialysis, an additional 1.2 g of protein per kg of body weight per day is required to replace the loss during dialysis.
When patients have to eat a lot of food continuously every day to get enough protein may cause the patients to feel bored. This will cause the lack of the amount of protein and other nutrients as prescribed. Especially in patients, the body may not recover, or not recover as quickly as it should. And not getting enough protein can negatively affect protein-intensive systems in the body, such as the immune system, blood and hormonal system.
Egg white is a good source of protein. It provides high protein and essential amino acids, 100 grams of egg white provides 22% protein, 26% Vitamin B2, and 29% Selenium of the daily needed values (Per cent daily values), no fat and cholesterol.
Besides, it's easy to find, inexpensive, and easy to digest. So, egg white is an ideal source of protein for patients and those who want to keep their bodies healthy. But eating egg white in the same way, such as boiled eggs, fried eggs, poached eggs, to get enough protein to meet daily needs, must eat in large quantities. It may cause consumers to feel fed up.
Processing egg white into new forms to make it more convenient and appetizing, at present, there are still a few. Most found products contain egg white and various flours are egg white crackers and egg white noodles. Products made from egg white without added starch, are egg white beverages, egg white tubes, and seasoned egg white cups.
In addition to ready-to-eat products, egg white is also processed into powdered egg white, to prolong the shelf life, more convenient transportation, and cheaper. Egg white powder contains 80-90% protein by weight. When mixed with water, it will turn back into egg white. It can be used for cooking as well as fresh egg white.
Besides the egg white, protein powders, such as whey protein or soy protein, are widely used in protein supplementation for both normal persons and patients. Both types are high quality, provide high protein and complete essential amino acids, by providing protein content of 80-90% by weight. They can be easily purchased in the market. Most
of the products are in powder form, and have evolved into food such as protein bars and cookies.
Alginate is polysaccharide (polysaccharide), extracted from the cell wall of brown algae. This long chain molecule contains (1,4)-linked β-D-mannuronate (M) and α-L-guluronate (G) residues. The human body is unable to digest alginate because it does not contain the enzyme that digests alginate. Alginate is hydrocolloid, commonly used in the food industry for thickening, gelling and film forming agents. Alginate has the ability to be gel at low temperatures, and is heat resistant. Alginate or alginic acid salt comes in many forms such as sodium alginate, calcium alginate. When sodium alginate is in calcium chloride solution (CaCl2), sodium ion on this polysaccharide chain is cross-linked with calcium ions. It is in a form called egg box, which looks like a solid gel. Alginate is widely used in processed meat products, fruits, pastas, as an ingredient in noodles, and used in the production of glass noodle (alginate noodle).
Nowadays, glass noodle is very popular, especially among consumers who want to reduce their consumption of starch and fat, glass noodle can be used to replace vermicelli in almost every menu. The main components of the glass noodle are sodium alginate solution (sodium alginate) and calcium chloride solution (calcium chloride). It does not contain carbohydrates and fats. Adding protein-rich food ingredients such as egg whites, soy protein, or whey protein in ingredient formula will make new types of glass noodles better nutritious. And it will make the noodles less stiff, white to light brown color, softer, closer texture to the starch noodles. It can be used to replace noodles and rice noodles beautifully. Besides, ingredients of glass noodles with egg whites and/or soy protein, and/or whey protein as an ingredient, can also be made into round or rice-similar shapes to replace pearls in beverages and desserts. Therefore, it is a good choice for patients and those who want to supplement protein with a variety of foods that are more appetizing.
According to the search, the protein noodle product or spherical and rice-similar protein granules made from egg whites and/or soy protein, and/or whey protein without the addition of starch and fat that can be used in food drinks and desserts, has not yet been found. Development of this product has the desired aim to develop a healthy diet that provides protein, free from starch and fat in the ingredients, which can be consumed frequently in daily life. The protein noodles can be eaten as noodles, which are popular among Thai people. And spherical and rice-similar protein shapes can be applied in popular beverages such as milk tea. It is considered food that benefits patients with chronic diseases such as kidney disease and cancer including those who want to maintain healthy lifestyles.
The invention involves starch-free, fat-free protein food that can be processed into noodles, spherical and rice-similar forms, which consists of 2 parts: the first part is boiled water, egg white powder and/or soy protein, and/or whey protein, and/or pea protein, and/or brown rice protein and sodium alginate, and the second part including boiled water and concentrated calcium chloride, as a solid gel agent.
Starch-free, fat-free protein food in noodles form has 0.5-5 mm diameter, spherical and rice-similar forms have 2-5 mm diameter. This product was developed from the gelling technique of sodium alginate and calcium chloride. Protein noodles and this spherical and rice-similar shapes protein are different from other protein products in the market. And it adds more value to egg white and protein powders.
