Norridge has wholesalers and manufacturers for various food products. Food is one of the basic needs in life, and many food preparations need one or more ingredients. Wholesalers and mnaufacturers work with a complex distribution system of farmers and ranchers for raw, unprocessed food supplies. These are then cooked and/or processed to get final products. Some commonly used food products that are manufactured and then sold by wholesale to retail markets includes dips, sauces, meat preparations, bread, condiments and dressings. Other food products include snacks such as chips and instand noodles. The manufacture of acidified food or process seafood products needs special training and certification. Manufacturers usually deal with one or more related products in Norridge. Wholesalers sell these products in bulk to retailers or dining establishments. A distribution service may also be offered.
