Issue 2: Understanding Industry Needs Market Access ü Unhampered access to markets where traceability is mandatory. Brand Protection ü Value-added Products ü ü ü Origin information promotes high quality and certified products Build product differentiation through verification of credence attributes Expand sales of high value or premium products to niche markets Minimise reputation and revenue losses arising from counterfeiting and fraudulent use of brand name. Liability ü Product recall ü ü Reduce costs, increase precision and efficiency while ü demonstrating control. Addresses consumer confidence, perception and negative publicity. Less vulnerable to liability due to ability to prove that it is not the source of a biosecurity or public health problem. Bio-security Speed and accuracy leads to avoidance or limitation of sales ban and mandatory destruction of assets.
IT How do we integrate? Scienc stry ems Traceability
Trace Element Profiling • ICP-MS is capable of parts per quadrillion detection limits • This is equivalent to being able to find an item of 1 cm 2 in 10, 000 football fields!!!
Typical Trace Element Profile
Australian Regions – Cabernet Forward stepwise LDA analyte selection: Ba, Si, Sr, Mg, Cs, Se, Nb, Th, Ni, Co, Na
Australian Regions – Chardonnay Forward stepwise LDA analyte selection: Si, Sr, Ba, Ga, Se, Be, Ni, Ta, Li, Pb, Mn, Ti, Mo, Nb
Case Study • 6 “suspect” samples and 6 “authentic” samples • “Authentic” samples are South Australian merlot • Are the “suspect” and “authentic” samples the same? • If not, can we validate the labelling claim of the “suspect” sample? i. e. Is it South Australian? Is it even Australian?
Is it Australian? Forward stepwise LDA analyte selection: Ba, Sr, Mn, Rb, Na, Si, Mg, Be, Cr, Al, V, Cs, Li, Fe, K, P, Ni, As, Zn, Ca
South Australian Merlot? Forward stepwise LDA analyte selection: Sr, Ni, Si, Li, K
