Determination of Mono-, Di-, and Triphosphates and Citrate in Shrimp by Ion Chromatography
Chanita Chantarasukon, Suparerk Tukkeeree, and Jeffrey Rohrer, Thermo Fisher Scientific
Polyphosphates are legally added to some food products such as meat and seafood to improve the appearance and texture of the product and increase the weight of the seafood. Ion chromatography (IC) is commonly used to determine large and small polyphosphates, as well as citrate. |

Determination of Phytic Acid in Soybeans and Black Sesame Seeds
Thunyarat Phesatcha, Suparerk Tukkeeree, and Jeffrey Rohrer, Thermo Fisher Scientific
Phytic acid is stored in the plant tissues of seeds and grains and its content levels in foods is important because it is not digested by humans and can prevent the absorption of iron and calcium by the intestine, even though as an antioxidant it can prevent carcinogenesis. |

HPLC Separation of All-Trans-ß-Carotene and its Iodine-Induced Isomers Using a C30 Column
Chen Jing, Xu Qun, and Jeffrey Rohrer, Thermo Fisher Scientific
Carotenoids, ß-Carotene being the most commercially important, have protective effects against serious disorders such as cancer, heart disease, and degenerative eye disease. In this method, a longer C30 alkyl chain of the stationary phase was ideal for separating hydrophobic structurally related isomers. |

Mogroside V Determination by HPLC with Charged Aerosol and UV Detections
Deanna Hurum and Jeff Rohrer, Thermo Fisher Scientific
Luo han kuo fruit has long been used in traditional Asian medicine because of numerous potential health benefits such as antioxidant activity, anticancer effects, and anti-hyperglycemic effects. The glycosides have also been isolated because they are intensely sweet and have been investigated as sugar substitutes and flavor enhancers. |

A Validated Method of Measuring Lactose in Milk
Thermo Fisher Scientific
Lactose, the major carbohydrate in milk, contributes to the sensory and functional properties of milk and has economic value since the price of milk is based on milk solids content. Measurement of milk's physical properties is used to determine the concentration of milk components and the quality of milk products. |
