Shelf life study

STC provides shelf life study (real time or accelerated) to assist food manufacturers to evaluate the shelf life of food products. The key parameters of shelf life study include microbiological quality, water activity and chemical properties such as peroxide value, acid value, etc.

  • Food quality test
  • Chemical analysis
  • Microbiological analysis
  • Pharmaceutical adulterants screening

Microbiological test

Total plate count, indicator organisms and pathogens

DNA / Genetic authentication

Genes never lie! DNA-based test can unmask the face of any biological species by analyzing and identifying their unique genetic codes. Together with our traditional food testing services, STC provides you with a more comprehensive food testing solution:

Food safety / composition

  • GM food (genetically-modified food) test
    Detection of GM elements in maize, rice, soybean, tomatoes, etc.
  • Food allergen test
    Detection of allergic substances such as gluten, wheat, crustaceans, fish, peanut, soybean, nuts, etc.
  • Animal ingredient adulteration
    Detection of porcine, bovine, fish, donkey, equine, etc.
  • Species identification
    Identification of animal and plant species

Valuable medicine authentication

  • Chinese medicine authentication
    Species identification of valuable Chinese medicines such as Donkey-hide gelatin, Velvet antler, Dried bulbus fritillariae cirrhosae, Cordyceps sinensis, bird nest, etc.

Bacterial / Viral test

  • Influenza A (Flu A) virus test
    Detection of influenza A virus in food and the environment
  • Food borne pathogen and virus test
    Detection of Campylobater, Norovirus, Hepatitis A, Rotavirus, etc.

Biotoxin detection

Seafood like shellfish (scallops, mussels, clams, oysters, etc.) is in fact nutritious and considered as delicacy by people in Hong Kong. Unlike other marine animals, shellfish is more susceptible to pollutants in the occasion of red tide or deterioration of water quality due to its fixed habitat. These pollutants may eventually be converted into different types of biotoxins and accumulated internally, giving rise to food poisoning in consumers. STC utilize molecular technique and develop tests on the following biotoxins:

  • Amnesic shellfish poison (ASP, domoic acid equivalent)
  • Diarrhetic shellfish poison (DSP, okadaic acid equivalent)
  • Neurotoxic shellfish poison (NSP, brevetoxin equivalent)
  • Paralytic shellfish poison (PSP, saxitoxin equivalent)
