METHOD OF EXTRACTING FOOD COMPONENT, FOOD INSPECTION METHOD AND FOOD INSPECTION KIT
摘要
It is intended to provide a technique for extracting a food component from a food by using a reducing agent which is inexpensive and has a mild reducing effect. A component in a food is extracted by mixing the food with an extractant containing a sulfite. The food extract thus obtained is brought into contact with a specific antibody capable of specifically recognizing a substance contained in a specific starting material to be inspected. Then, the presence or absence of the specific starting material and/or the amount thereof in the food is determined by using an immunoassay method. Further, it is intended to provide a food inspection kit for determining the presence or absence of a specific starting material and/or the amount thereof in a food which comprises: (1) an extractant and a sulfite to be added to the extractant, or an extractant containing a sulfite, and (2) an antibody capable of specifically recognizing a substance contained in a specific starting material to be inspected.
