Study Notes
Microbial Origins in Fresh Vegetables
- Fresh vegetables can have microbial origins from soil, water, air, and human handling
- Microorganisms can be present on the surface or interior of the vegetables
Conditions Increasing Spoilage in Vegetables
- High temperatures and humidity increase the chance of spoilage
- Physical damage, bruising, and cuts provide entry points for microorganisms
- High water activity and nutrient-rich environments facilitate microbial growth
Microbial Spoilage in Fruits and Vegetables
- Microbial spoilage is commonly referred to as "decay" or "rot"
- Soft rot, slimy rot, and grey mold are types of microbial spoilage
Microbial Species Causing Spoilage
- Fungi, such as Botrytis, Alternaria, and Fusarium, are common causes of spoilage
- Bacteria, such as Pseudomonas, Erwinia, and Xanthomonas, are associated with vegetable spoilage
Bacterial Species of Concern
- Pseudomonas fluorescens, Pseudomonas viridiflava, and Erwinia carotovora are bacterial species of concern
Most Common Cause of Spoilage
- The most common cause of spoilage in fresh vegetables and fruits is fungal growth
Microorganism Sources
- Microorganisms found in fresh vegetables primarily come from the soil, water, and air during growing, harvesting, and handling
Microbial Vegetable Spoilage Terms
- "Spoilage" or "decay" are common terms used to describe microbial vegetable spoilage
