Product Spoilage Investigations

The Problem

Have you ever had the unfortunate experience of finding bulging packages or spoiled food before the end of its expiration date? Were you left puzzled by the cause of the rapid spoilage? Did you need an immediate and practical action plan to correct the issue?

Believe it or not, premature food spoilage is a common problem that continues to trouble food manufacturers today. Some of the major factors include sanitation practice, ingredient quality, processing variability, and environmental monitoring. Examining these key components can help processors narrow down the cause of the spoilage and develop practical solutions.

At AEMTEK, we offer expert services in spoilage investigations and environmental monitoring strategy to help food and beverage industries take immediate corrective actions.

The Solution

Our seasoned team of microbiologists and mycologists at AEMTEK can support you through your toughest product spoilage challenges. We provide investigative solutions including:

  • Microbiological testing and identification of the spoilage containment
  • Environmental monitoring plan design and verification
  • On-site facility assessments and sampling
  • Air and environmental sampling for fungal spores and bacteria
  • Technical consultation and corrective action plan development

Antimicrobial Efficacy Testing / Preservative Efficacy Testing (PET)

Antimicrobial Efficacy Testing is also known as Preservative Efficacy Testing (PET). This testing evaluates how effective an antimicrobial agent, or preservative, is at inhibiting the growth of microorganisms in a product.

The effectiveness of the antimicrobial agent is determined by measuring the microbial load of a product after it has been inoculated in the laboratory.

Our experienced scientific team can adhere to standard procedures or develop specific methods according to your needs. AEMTEK’s standard PET testing includes 3-4 test points over a period of 28 days. Our laboratory follows the USP <51> method with inoculation of all 5 microorganisms including:

  1. Candida albicans
  2. Aspergillus brasiliensis
  3. Escherichia coli
  4. Pseudomonas aeruginosa
  5. Staphylococcus aureus

We perform testing following the procedures outlined by the U.S. Pharmacopeia, ASTM, NCCLS, AOAC, etc. Testing is conducted in adherence to rigid quality control requirements to provide you with reliable and reproducible data for optimizing your services and/or formulating your products.

Our laboratory is staffed with experienced Ph.D. microbiologists and mycologists and equipped with advanced instrumentation to ensure the generation of scientifically accurate data. AEMTEK follows a strict quality assurance program and participates in accreditation programs.
