QUOTE OF THE MONTH:

"Chemistry must become the astronomy of the molecular world.������������������"

Alfred Werner (12 December 1866 - 15 November 1919)
Swiss chemist whose founding������������������research������������������into the������������������structure������������������of coordination compounds brought him the 1913 Nobel Prize for Chemistry. He demonstrated that stereochemistry was not just the property of carbon compounds, but was general to the whole of chemistry. His theory of chemical coordination (1893) recognized that many metals appeared to show variable valence and form complex compounds. Certain metals, such as cobalt and platinum, were capable through their secondary valences of joining to themselves a certain number of atoms or molecules. These were termed by Werner “coordination compounds.”������������������and the maximum number of atoms (or “ligands”������������������as he called them) that can be joined to the central metal is its coordination number.

The Oxitest Method for the determination of oxidation stability of food fats and oils)

The Oxitest Method is an International recognized analytical technique for the determination of the oxidation stability of food, fats and oils.

Every food, feed and other products containing lipids (creams, lip balms, body lotions, wax etc...) undergoes oxidation of the contained fat portion, which causes unpleasant flavor, bad smell and the loss of its natural sensorial qualities.

Many factors influence lipid oxidation (and the shelf life of the sample) such as the ambient temperature, exposure to heat, the composition of Fatty Acids and its degree of saturation, the concentration of oxygen etc.

Predicting oxidation stability of raw material and finished products is crucial information for the food industry with operational and economic implications.

The stability tests performed with the VELP OXITEST reactor accelerates the oxidation process which in normal conditions would take weeks or months and provide fast, accurate and reliable results.

The Oxitest Method has been recognized as an AOCS International Standard Procedure (Cd 12c-16) for the determination of oxidation stability of food, fats and oil and, effective from May 2017, will be published in the 7th Edition of the Official Methods and Recommended Practices of the AOCS, (American Oil Chemist���������������������������s Society).

This is only the last step of a long run that has seen cooperation between VELP Scientifica and research centers, universities and laboratories from all over the world, for developing the instrument and the method and tailor it to their needs.

The OXITEST reactor subjects the sample to a high-oxidative stress environment in order to evaluate, in a short period of time, the resistance to fat oxidation.

With the OXITEST Method, the stability test is performed directly on the sample as it is, be it solid, liquid or doughy.

The method key advantage is that preliminary fat extraction is never required and this guarantees representative results.

In fact, other components of a product like chemical oxidants or transition metal can promote oxidation and the use of extracted matter may not be a suitable predictor of stability. The OXITEST reactor is entirely controlled via PC through the intuitive OXISoftTM™ software and for the set-up of the analysis, the reactor needs to be connected to Oxygen (Grade 5.0) as shown in figure 1.

The instrument features two thermostated and hermetically sealed titanium chambers in which oxygen is purged until the pressure within both chambers is between 0���������������������������8 bar. The temperature is then set to the desired level (room temp. to 110 ������������������C).

The VELP Oxitest measures the absolute pressure change inside the two chambers monitoring the oxygen uptake of the active components of the samples, and automatically generates a value expressed in time, called the Induction Period (IP). The longer the IP, the more resistant a sample is to oxidation over the life of the sample.

The information provided by the Oxitest method along with other tests (i.e. microbial analysis, peroxide values etc.) are crucial for the shelf life study of the products.

The OXITEST comes with several pre-installed methods and it is also possible to create your own customized analysis. The OXISoftTM™ manages all the analysis steps and easily provides valuable data to enable researchers to:

• Estimate shelf-life by testing the sample at different temperatures and elaborating an experimental curve that predicts the behavior at room temperature;
• Study oxidation at different storage time intervals;
• Evaluate the adequacy of storage conditions;
• Evaluate the best packaging solution;
• Compare the oxidative stability of different formulas for food preparations;
• Evaluate the oxidative stability of vegetable oils of different botanical origin;
• Evaluate the effectiveness of antioxidants;
• Control the quality of incoming raw materials and outgoing finished products.

SCIENCE TEACHERS��������������������������� ASSOCIATION OF NSW YOUNG SCIENTIST AWARDS 2016

Rowe Scientific Pty Ltd Equipment Prize - Awarded to the best three secondary students who best utilise scientific equipment in designing their solution to a scientific or technological problem.

1st: Jennifer Xu (with Mr John Dwyer, NSW State Manager, Rowe Scientific Pty Ltd), PLC Sydney, Probiotics or Nobiotics?

Can the probiotics touted for gut health make it through the hostile environment of the stomach? Jennifer tested the tolerance of the common probiotic Lactobacillus acidophilus by simulating the conditions in the stomach and small intestine and incubating the mixture on agar in an anaerobic environment. Her results showed that most of the bacterial cells survived.

2nd: Hingis Li, PLC Sydney, Fertiliser and its effect on lake water

Overgrowth of algae due to excess nutrients in waterways is a real problem associated with industrial farming. Hingis explored the effect of varying concentrations of fertiliser on the properties of water, including pH, light transmission and dissolved oxygen, making effective use of a variety of probes and meters in the process.

3rd: William Harris (with Mr John Dwyer, NSW State Manager, Rowe Scientific Pty Ltd), Wollondilly Anglican College, Accuracy of dataloggers and probes in Streamwatch

The Streamwatch program involves schools and other groups contributing to regular monitoring of our waterways. William investigated whether the monitoring process could be improved with greater use of dataloggers. He found that there was some variation between the two methods, and so further tests would be needed to determine which was most accurate.

Rowe Scientific Pty Ltd School Grants - STANSW Young Scientist awarded 3 school grants of $1,000 to be distributed amongst a few hard-working science students from each school. To be eligible the school must have been located in a rural or remote location and had two or more entries from Year 7-12 students in the 2016 STANSW Young Scientist Awards

Grant Winner No. 1: Eden Marine High School
