The following are examples of topics in food physical chemistry that are of interest to both the food industry and food science: Starch, 800x magnified, under polarized light Macaroni is an extruded hollow pasta. Water in foods Local structure in liquid water; Micro-crystallization in ice cream emulsions
Classically, "water of crystallization" refers to water that is found in the crystalline framework of a metal complex or a salt, which is not directly bonded to the metal cation. Upon crystallization from water, or water-containing solvents , many compounds incorporate water molecules in their crystalline frameworks.
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 a type of resistant starch. Chemical modification of starches can reduce or enhance the retrogradation ...
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.
Many organic molecules, as well as inorganic molecules, form crystals that incorporate water into the crystalline structure without chemical alteration of the organic molecule (water of crystallization). The sugar trehalose, for example, exists in both an anhydrous form (melting point 203 °C) and as a dihydrate (melting point 97 °C).
Comparison of blooming (left) and regular chocolate bars Fat bloom on the surface of chocolate with a marzipan filling Fat bloom viewed under an optical microscope. Chocolate bloom is either of two types of whitish coating that can appear on the surface of chocolate: fat bloom, caused by changes in the fat crystals in the chocolate; and sugar bloom, due to crystals formed by the action of ...
Snowflakes are a very well-known example, where subtle differences in crystal growth conditions result in different geometries. Crystallized honey. There are many examples of natural process that involve crystallization. Geological time scale process examples include: Natural (mineral) crystal formation (see also gemstone);
Inverted sugar syrup, also called invert syrup, invert sugar, [1] simple syrup, sugar syrup, sugar water, bar syrup, syrup USP, or sucrose inversion, is a syrup mixture of the monosaccharides glucose and fructose, that is made by hydrolytic saccharification of the disaccharide sucrose.
