Thermal Processing Determination Time for Fermented and Acidified Indigenes Iranian Vegetables

Thermal processing determination time for fermented and acidified indigenes Iranian vegetables

Vegetables may be preserved by fermentation, direct acidification, or a combination of these, along with pasteurization, to yield products with an extended shelf life and enhanced safety.  Effect of lowering the pH, either by adding acid or lactic fermentation, on thermal process requirements for canned vegetables was investigated. Malic acid was preferred for acidification of canned vegetables...

Use of Linear Models for Thermal Processing of Acidified Foods

Acidified vegetable products with a ph above 3.3 must be heat processed to assure the destruction of Escherichia coli O157:h7, Salmonella enterica, Listeria monocytogenes, and other pathogenic bacteria that might be present in the product. Recently, the Food and Drug Administration has required that linear models for heat process data be used with electronic process filing forms. Existing recom...

Fermented Vegetables Historical PersPective

Historical PersPective The wide variety of fermented foods can be classified by the products of the fermentation, such as alcohol (beer, wine); organic acids, including lactic acid and acetic acid (vegetables, dairy); carbon dioxide (bread); and amino acids or peptides from protein (fish fermentations and others) (35, 56, 96, 97). Food fermentation is one of the earliest technologies developed ...

Dry and Semi-Dry Fermented and Direct Acidified Sausage Validation

In 1994, an outbreak of E. coli O157:H7 infection was linked to dry, fermented, pork and beef salami. In response to this first implication of a dry fermented sausage product, the United States Department of Agriculture/Food Safety Inspection Service developed guidelines requiring sausage manufacturers to validate that their processes achieve a five-log reduction of E. coli O157:H7. Various val...

Dry and Semi-Dry Fermented and Direct Acidified Sausage Validation

range for these products is 4.7-4.9, whereas, pepperoni has a slightly lower pH range of 4.5-4.8 and a lower MPR of 1.6:1 as required by FSIS (FSIS, 1986). The moisture content for these products ranges from 25-39%. All of these products, because of their moisture-toprotein ratios, are considered shelf stable (FSIS, 1986; Ricke and Keeton, 1997). Semidry sausages such as summer sausage, cervela...
