Name of the ingredient
Chicken sternum cartilage powder (Approved Biological Name (ABN), ingredient ID: 143048).
Definition of the ingredient
Chicken sternum cartilage powder is a non-GMO substance derived from sanitised chicken sternum cartilage which are grounded and subjected to a two-step dehydration process using potassium chloride. The dehydration process is undertaken at a temperature sufficient to eliminate pathogens of concern. After drying the ground sternums are milled and sieved. Chicken sternum cartilage powder is derived from the sternum of chickens that are fit for human consumption.

|
While substance manufacturers are encouraged to include limits for objectionable microorganisms, it is the product into which those substances are formulated that is subject to a legally binding set of criteria. The Therapeutic Goods Order No. 100 'Microbiological Standards for Medicines' mandates that any finished product that contains the ingredient, alone or in combination with other ingredients, must comply with the microbial acceptance criteria set by Clause 11 of the Order. |

Hydroxyproline represents about 12.6% of collagen by mass. Use the following equation to convert hydroxyproline content into total collagen: Hydroxyproline level (mg/g sample) × 8 = Total Collagen (mg/g sample) 2. ELISA Test Methodology - % Undenatured type-II collagen: Incubator shaker temperature: 4°C; Incubator shaker speed: 110 rpm; Centrifuge speed: 600 g and 15200 g; Centrifuge temperature: 4°C; Plate reader: 490 nm; Data for collagen standards fit to a 4-parameter logistic equation: Y = d + (a-d) / (1+(X/c) b)
