Processing of Fruits and Vegetables
The nitrate and nitrite contents were determined in canned vegetable-based infant foods of five varieties. Furthermore, changes in nitrate content during industrial processing were studied. Samples were taken from raw materials, homogenized mixtures, and final products after sterilization, and then analyzed for nitrate and nitrite content by high-pressure liquid chromatography. The final nitrate concentration in infant foods depends mainly on the initial nitrate content of the raw-vegetable mixture.
The effect of storage time 24 and 48 h and temperature 4 to 6 degrees C and 20 to 22 degrees C on nitrate and nitrite content in opened canned infant-food samples was studied. The nitrite content in all analyzed samples was below the quantification limit. Storage requirements of industrial manufacturers must be followed strictly. Opened can foods, stored under refrigerated conditions, have to be consumed within 2 days, as recommended by manufacturers.
The infant-food producers must pay more attention to the quality of raw materials. Nitrate content analyses should be added as compulsory tests to the quality assurance programs.

The report extensively provides the market share, growth, trends and forecasts for the period Canning of food products is a food preservation technique that uses a mix of heating and storing procedures in airtight containers to significantly extend the shelf life of the foods by killing all the microorganisms that cause food spoilage. Virtually any variety of food product that is processed or harvested can be canned. Canned tomatoes is the main product group imported into the EU.
Canned Food: Good or Bad?
Accidental freezing of canned foods will not cause spoilage unless jars become unsealed and recontaminated. However, freezing and thawing may soften food. If jars must be stored where they may freeze, wrap them in newspapers, place them in heavy cartons, and cover with more newspapers and blankets. Do not taste food from a jar with an unsealed lid or food which shows signs of spoilage. You can more easily detect some types of spoilage in jars stored without screw bands. Growth of spoilage bacteria and yeast produces gas which pressurizes the food, swells lids and breaks jar seals. Carefully discard any jar of spoiled food to prevent possible illness to you, your family and pets. You must detoxify the container, lid and all the contents before disposal.
What It Says on the Tin: A Brief History of Canned Food
Food processing is the transformation of raw ingredients into food, or of food into other forms. Food processing typically takes clean, harvested crops or butchered animal products and uses these to produce attractive, marketable and often long shelf-life food products. Benefits of food processing include toxin removal, preservation, easing marketing and distribution tasks, and increasing food consistency. In addition, it increases yearly availability of many foods, enables transportation of delicate perishable foods across long distances and makes many kinds of foods safe to eat by de-activating spoilage and pathogenic micro-organisms.
The market for processed fruit and vegetables is estimated to surpass USD billion by ; according to a new research report by Global Market Insights, Inc. The report shows that North America held the largest market share in and Asia-Pacific is expected to show the highest growth. Shifting consumer preference towards RTE food, and canned products will supplement market expansion. Additionally, technological innovation in dispensation techniques has enabled the manufactures to launch new products with a higher amount of nutritional content.

Foods such as fruit, vegetables, meat, fish, or a combination of these foods e. Canned foods are washed, prepared and filled into metal containers along with a canning fluid e. The food is heat treated to produce a commercially sterile shelf-stable product with an air-tight vacuum seal.
Some people claim they contain harmful ingredients and should be avoided. Others say canned foods can be a part of a healthy diet. Canning was first developed in the late 18th century as a way to provide a stable food source for soldiers and sailors at war. Common canned foods include fruits , vegetables, beans, soups, meats, and seafood. Canned foods are often thought to be less nutritious than fresh or frozen foods , but research shows that this is not always true. Protein, carbs, and fat are unaffected by the process.
Canning , method of preserving food from spoilage by storing it in containers that are hermetically sealed and then sterilized by heat. The process was invented after prolonged research by Nicolas Appert of France in , in response to a call by his government for a means of preserving food for army and navy use. It was 50 years before Louis Pasteur was able to explain why the food so treated did not spoil: the heat killed the microorganisms in the food, and the sealing kept other microorganisms from entering the jar. In Peter Durand of England patented the use of tin-coated iron cans instead of bottles, and by he was supplying canned food to the Royal Navy in large quantities. European canning methods reached the United States soon thereafter, and that country eventually became the world leader in both automated canning processes and total can production. In the late 19th century, Samuel C. Prescott and William Underwood of the United States set canning on a scientific basis by describing specific time-temperature heating requirements for sterilizing canned foods. Originally, cans consisted of a sheet of tin-plated iron that was rolled into a cylinder known as the body , onto which the top and bottom were manually soldered.

Canning is a method of preserving food in which the food contents are processed and sealed in an airtight container jars like Mason jars , and steel and tin cans. Canning provides a shelf life typically ranging from one to five years, although under specific circumstances it can be much longer. In , samples of canned food from the wreck of the Bertrand , a steamboat that sank in the Missouri River in , were tested by the National Food Processors Association. Although appearance, smell and vitamin content had deteriorated, there was no trace of microbial growth and the year-old food was determined to be still safe to eat.
