Food testing

  Food and beverages must meet international requirements to ensure their safety, content, sanitation, and quality.  HCT’s Food and Drug Division performs the following food safety testing:
★. Nutritional Content Testing 
★. Pesticide Residue Testing 
★. Veterinary Drug Residue Testing 
★. Food Additive Testing 
★. Food Microbiology Testing 
★. Melamine Testing 
★. Heavy Metal and Trace Element Testing 
Nutritional Content
    HCT tests to determine the macronutrient and micronutrient contents of food to ensure the accurate nutrient labeling of food products.  In addition, the labs test for pH values, acidity, alkalinity, particle size, and density of food content. The most commonly tested nutrients are:

PCalories
Calories Nicotinic Acid Magnesium  Vitamin A
Protein  Folic Acid  Iron  Vitamin D
Fat  Pantothenate Acid  Zinc  Vitamin E
Saturated Fatty Acid Biotin  Iodine  Vitamin K
Unsaturated Fatty Acid  Cholin  Selenium  Vitamin B1
Trans Fatty Acid  Calcium  Copper  Vitamin B2
Cholesterol  Phosphorus  Fluorine  Vitamin B6
Carbohydrate  Potassium  Chromium  Vitamin B12
Dietary Fiber Sodium Manganese Vitamin C
 
Sodium  Manganese  Vitamin C

Pesticide Residues
    Pesticides enter food items in a number of ways.  Pesticides may contaminate food directly through crop dusting or other means of spraying of fruits and vegetables that are sold to consumers; pesticides enter into the food chain indirectly through the environment (soil, air, and water); pesticides may also be present in animal feeds consumed by animals that are later butchered and sold.
    HCT’s labs possess the capacity to test for over 500 different pesticide residues.  The most common types of pesticide residues tested are listed below:
★Organochlorines – HCH, DDT, PCB, Heptachlor, Aldrin, Dieldrin, PCNB
★Organophosphoruses – Methamidophos, Dipterex, Fenitrothion, Malathion, Fosfamid, Phorate
★Pyrethroids – Fenpropathrin, Decamethrin, Cypermethrin, Fenvalerate
★Urethate – Carbendazim, Dithiocarbamates
Veterinary Drug Residues
    Veterinary drugs are present in meats sold on the market due to the heavy use of drugs administered to animals in farming.  Such drugs are potentially toxic to humans and may cause resistance to certain bacteria.  The most common veterinary drug residues tested by HCT are:
★Tetracyclines – Tetracycline, Terramycin, Aureomycin, Doxycycline
★Nitrofurans – Furacilinum, Nitrofurantoin, Furazolidone, Nitrofuran Metabolites
★Sulfonamides – Sulfabenzamide, Sulfadiazine, Sulfanitran, Sulfaquinoxaline, Sulfathiozole
★Quinolones – Norfioaxin, Ciprofloxacin, Sarafloxacin, Enrofloxacin
★Penicillins – Dicloxacillin, Cloxacillin, Penicillin G, Amoxicillin
★Stimulants – Clenbuterol, Ractopamine, Salbutamol
Food Additives
    Food additives are an integral part of the food industry, but different additives must be controlled to meet country-specific standards before entrance on the market.  The most common food additives tested by HCT are the following:
★Preservatives – Sorbic Acid, Benzoic Acid, Calcium Proprionate
★Colorants – Kermes Red, Amaranth, Limon Yellow, Sundown Yellow, Brilliant Bluish,    Allure Red, Ponceau 4R
★Sweeteners – Saccharin Sodium, Sodium Cyclamate, Acesulfame
★Antioxidants – BHA, BHT, TBHQ, Phytic Acid
★Bleaching Agents – Sulphite, Sulphur Dioxide
★Pigments – Nitrate, Nitrite
★Powder Treatment Reagents – Benzoyl Peroxide
Food Microbiology
    Microbes present in food may lead to severe illness or even death.  Different bacteria, viruses, fungi, and other microorganisms may damage a company’s reputation should an outbreak occur.  The most common microorganisms in food tested by HCT are the following:
★Streptococcus hemolyticus
★Listeria Monocytogenes
★Coliform Group
★Shigella
★Fecal Coliform
★Vibrio Parahaemolyticus
★Staphylococcus Aureus
★Fungi
★Enterobacter Sakazakii
★Yeasts
★Salmonella
