Knowledge: Soy Protein
Isolated Soy Protein & Hydrolysed Vegetable Protein
Soybeans are a great quality protein because their amino acid content is similar to that in meat, and they are a good source of fiber, minerals, and complex carbs.
Isolated Soy Protein
Isolated soy protein is a protein that is purified from high quality non-GMO defatted soybean flakes, which makes its protein content as high as 90% and it does not contain other carbohydrates and fats. Because of this, it has a neutral flavour and will cause less flatulence than soy flours.
Isolated soy protein is a complete protein since it provides all of the essential amino acids for human nutrition. It is one of the least expensive sources of dietary protein. And can be important to many vegetarians and vegans. Other plant protein does not contain the complete nutritional value that soy does.
Isoflavones are one of the most studied bioactive compounds in soybeans, and are closely associated with proteins. Soy foods and soy-based infant formulas are rich sources of isoflavones, and contain about 3-5.1 mg/g protein. Isoflavones are the major soy phytoestrogens, including genistin, daidzin and glycitein. Both genistin and daidzin are conjugated to sugars and present as glycosides in soybeans and most of the soy foods in Western diets. Glycoside isoflavones cannot be absorbed in the body unless hydrolyzed and converted to aglycones, genistein and daidzein by intestinal microflora or in vitro fermentation. In addition, Daidzin or daidzein can be metabolized to equol by certain strains of intestinal microflora in the gastrointestinal tract. However, only 30–50% of the adult population can produce and excrete equol in the urine after daily ingestion of soy foods.
Hydrolysed Vegetable Protein (HVP)
For more than hundred years, Hydrolysed Vegetable Proteins have been used as ingredients in a wide range of foods, primarily as an agent to enhance food flavors. With the development of the Food Technology, BIONUTRICIA has expanded its product in turning Hydrolysed vegetable protein into powder that is suitable for manufacturing into a wide range of seasoning products.
HVP is made from single or combined plant-based protein sources, including soy, corn, and wheat. Protein molecules are long chains of amino acids linked together by peptide bonds. These bonds are broken to produce HVP using hydrochloric acid and then neutralized with sodium hydroxide, which leaves behind sodium chloride (table salt). This is followed by filtration, concentration and spray drying.\nOne of the amino acids in HVP is glutamic acid. Consumers are more familiar with glutamic acid in the form of its sodium salt monosodium glutamate, or MSG. Glutamic acid is giving the taste of umami, which is one of the five basic tastes that has been described as meaty and savory. This is why this flavor enhancer has traditionally been consumed in many Asian countries.
HVP is often used as condiments, and can also be used as flavor enhancers in soy sauce, soups, meat products and snack foods. HVP can also increase the nutrition of food, as it has 8 essential amino acids that are indispensable to the human body, as well as other amino acids.
In response to negative side effects reported in regards to MSG, manufactures have increasingly relied on HVP as an alternative to providing the desired organoleptic properties of the end product. Due to the similar amino acid present in HVP and MSG, consumers may perceive HVP as a healthier alternative to MSG because it is made from vegetable proteins.
Isolated soy protein powder is the perfect option when someone needs fuel throughout the day or as a protein boost after workout. They are unflavoured meaning can be added to any recipes, favourite shakes, smoothies, or the production of baked goods. Including isolated soy protein in pregnancy diets is also an alternative for lactose intolerant mothers. For individuals who want to replace animal based foods that contain saturated fats, isolated soy protein also acts as a good substitute since it is top in the plant-based protein list.
It is a good emulsifying agent due to the natural presence of soybean lecithin. So it can mix oil and water to become an emulsion for wider application. It also provides good gel strength. In food application, it can be added in gravy or meat products to hold water and preserve the taste and flavour of meat products. Soy isolates are mainly used to improve the texture of meat products, but are also used to increase protein content, to enhance moisture retention, and as an emulsifier.

May reduce risk of gestational diabetes mellitus (GDM) in pregnant women
|In vivo study on the association between soy intake and risk of gestational diabetes mellitus in pregnant women
|Pregnant women between 13 and 24 weeks of gestation (n = 224)
|Semi-quantitative food frequency questionnaire
A total of 36 pregnant women were diagnosed with GDM. The incidence of GDM in the insufficient group was 12.5% higher than that in the control group (χ2 = 6.409, P = 0.011).
|Insufficient soy intake may increase the risk of GDM, suggesting adequate soy intake may have a beneficial role in the prevention of GDM.
