Frozen vegetables manufacture

French fries are made from potatoes that have been cut into thin strips (around 1 cm square in cross-section), washed briefly in cold water, partly dried to remove surface moisture and deep fired in vegetable oil at around 180°C to a light golden color. The final product comprises around 10% fat, most of which is retained on the surface. Frozen fry manufacturers ship their products raw, par-fried, or partially cooked and drizzled with oil for baking, to suit the end user. The product is frozen at —40°C and stored at —20°C. Moisture content needs to be less than 70% in par-fried fries to prevent limpness and separation of the interior and the cmst. Heterogeneity in moisture content between strips can result in variability in texture. Fr5dng is finished by immersing the frozen product in deep fat at about 200°C until the desired color and texture are achieved. 

Food products may include frozen produce, canned produce, pasta, sauces in jars, prepared meals or pizzas. It is important to work closely with the manufacturer, in working out the best types of ingredients to use, depending on the manufacturing facilities available. For example, frozen fruit and vegetable processors require a specific size and quality, pasta and bread manufacturers will have their specific requirement of the variety and grade of wheat. They require consistent quality and volume so as to be able to produce a consistent end product. As with restaurants, it is important to build a good relationship with your processor and to keep the manufacturer informed of any potential problems. This allows them to take other action to ensure their production does not suffer.

Food Processing. The manufacture of food stuffs such as dairy products, breakfast foods, soups, bread, canned goods, frozen foods, and other processed foods, as well as meats, fruits, and vegetables, use engineering operations such as heat transfer to heat or cool.
