Contamination of Vegetables And Fruit Preservation of Vegetables Microorganisms on the surfaces of freshly picked fruits and vegetables comprise not just the regular surface flora, but also microorganisms from the soil and water, and possibly plant diseases. Additionally, a variety of moulds and occasionally a few yeasts may be present. Some germs may thrive between … Read more
The term “yeast”, which is similar to mold, is often used, but it can be difficult to define. It refers to fungi that are not filamentous, but unicellular, ovoid, or spheroid, and can reproduce by budding and fission. Yeasts can be beneficial or harmful to foods. Yeast fermentations play a role in the production of bread, wine, vinegar, and surface-ripened dairy products. Yeasts can be grown for enzymes or for food. When yeasts cause spoilage in sauerkraut, fruit juices and sirups as well as honey, jellies, meats and wine, they are considered undesirable.

The growing plants carry a common microbiome on their surfaces. They could be contaminated by external sources. Animals too have a normal surface flora, as well as an intestinal one. They also release organisms through excretions and secretions. They can are also contaminated by outside sources. Animals and plants with parasitic diseases, of course, carry the pathogen responsible for the illness. The healthy tissues that are inside both animals and plants nevertheless are found to have a small number of living microorganisms or none at all.
What are Molds? Morphological Characteristics of Molds In their classification and identification, they are based on their morphology (i.e. their form and structure as determined by their microscopic and macroscopic appearance). 1. Hyphae and Mycelium of Molds 2. Reproductive Parts or Structures of Molds (a) Asexual Spores of Molds (b) Sexual Spores of Molds These … Read more
To identify bacteria in food, microscopic examination is the first step. It can determine the structure, shape, size, aggregation and staining reactions. These characteristics could be particularly important.
When food is called “spoiled”, it usually means that there is decay or decomposition of an unfavorable nature. Foods unfit for consumption are not considered spoiled. Spoiling could be caused by one or more of these:
