Starch gelatinization. Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water acts as a plasticizer.
Pack of modified food starch, a food additive which is prepared by treating starch or starch granules. Modified starch, also called starch derivatives, is prepared by physically, enzymatically, or chemically treating native starch to change its properties. [1] Modified starches are used in practically all starch applications, such as in food ...
Retrogradation can expel water from the polymer network. This process is known as syneresis. A small amount of water can be seen on top of the gel. Retrogradation is directly related to the staling or aging of bread. [3] Retrograded starch is less digestible (see resistant starch). Chemical modification of starches can reduce or enhance the ...
Hydrogenated starch hydrolysates (HSHs), also known as polyglycitol syrup (INS 964), are mixtures of several sugar alcohols (a type of sugar substitute). Hydrogenated starch hydrolysates were developed by the Swedish company Lyckeby Starch in the 1960s. [1] The HSH family of polyols is an approved food ingredient in Canada, Japan, and Australia.
Resistant starch. A specially developed strain of barley, high in resistant starch. Resistant starch (RS) is starch, including its degradation products, that escapes from digestion in the small intestine of healthy individuals. [1][2] Resistant starch occurs naturally in foods, but it can also be added as part of dried raw foods, or used as an ...
Potato starch is a refined starch, containing minimal protein or fat. This gives the powder a clear white colour, and the cooked starch typical characteristics of neutral taste, good clarity, high binding strength, long texture, and minimal tendency to foaming or yellowing of the solution. Potato starch contains approximately 800 ppm phosphate ...
Corn starch is a common food ingredient, often used to thicken sauces or soups, and to make corn syrup and other sugars. [3] Corn starch is versatile, easily modified, and finds many uses in industry such as adhesives, in paper products, as an anti-sticking agent, and textile manufacturing. [4] It has medical uses as well, such as to supply ...
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Acetylated starch, E1420 in the E number scheme of food additives, is a modified starch. These are not absorbed intact by the gut, but are significantly hydrolysed by intestinal enzymes and then fermented by intestinal microbiota.
