What is meaning of ISB in food?

ISB stands for international standard book number. It is a unique numeric code that identifies a book or book-like product such as a film or sound recording. The number is assigned by the International ISBN Agency, a non-profit organization based in London.

The ISBN was created in 1967 by the International Publishers Association (IPA) as a way to streamline the ordering and distribution of books. The ISBN is used by libraries, bookstores, and publishers to identify and track books. It also helps to prevent duplicate entries in library catalogs and bookstores.

The ISBN consists of 10 digits, which are divided into four parts:

* Prefix: The prefix is a one-digit number that identifies the language or country of origin of the book.

* Group identifier: The group identifier is a two-digit number that identifies the publisher or publishing group.

* Title identifier: The title identifier is a six-digit number that identifies the specific book.

* Check digit: The check digit is a one-digit number that is calculated based on the other numbers in the ISBN. It is used to verify the accuracy of the ISBN.

The ISBN is printed on the back cover of books and on the inside of the front cover. It is also included in the book's metadata.
