Standard for Olive Oil

Standards Australia is working on an overall Australian standard for all grades of olive oil. The objectives are to recognise the natural differences that are seen in olive oil from down under and to stop consumer confusion over the various nomenclatures used to describe refined olive oils. The move to creating a new standard was catalysed somewhat by an article in Choice magazine in Australia reporting that over 50% of EV oils nalysed by a qualified laboratory(Modern Olives) did not meet the analytical requirements.Similar results have been reported in the past by our own Consumer magazine.

Choice, (2010) July p38

There has also been published recently a new USDA standard for all grades of olive oil, primarily to prevent adulteration and the confusion over the different types of olive oil.


Olive oils in the NZ supermarkets

The recent issue of the Koru magazine from Air New Zealand carries an upbeat article about NZ olive oils. It is good to see them getting the publicity they deserve. Whilst the quality of these oils is very good, they are also quite expensive yet competitively priced Extra virgin oil are starting to appear on the supermarket shelves.

The latest edition of The Orchardist (July, 2010) has an interesting article on Simunovich Olive Estate in Bombay.

Eye health

Nutrition ingredient suppliers have for several years been promoting the use of lutein in eye health to prevent macular degeneration.  A recent paper published by workers at the Department of ophthalmology, Dijon in France has recently published a paper doing a study on the role of lipids and lutein in high health.

Butter and spreads in our supermarkets

On a recent trip to the United States of America and a visit to the local high-class supermarkets it was observed American butter occupies almost 2/3 of the refrigerator shelf space for yellow fat spreads. An interesting development which this author was told was due to the suspicions of the consumers surrounding any yellow fat product in tubs.  We in NZ are seeing a diversity of Dairy blends and butter spreads on our shelves. The recent relaunch of Mainland Butter soft which is the original spreadable butter (with no oil) is good to see. This is an excellent tasting product.

Antioxidant effect of spices in hamburgers

Spices that were traditionally used to preserve foods are now studied for their antioxidant effects that are predominantly due to phenolic compounds. Malondialdehyde were chosen as the marker of oxidation in a study of spices in hamburgers. A spice mixture of cloves, cinnamon, oregano, rosemary, ginger, black pepper, paprika and garlic powders, significantly reduced the incidence of malondialdehyde during cooking.

ALA with probiotics

Studies have been carried out on mice with Bifidobacterium and ALA9alpha linolenic acid) showed that the co-feeding resulted in higher levels of EPA in the liver than without the probiotic. A very interesting observation from a nutritional perspective. So take yoghurt with your flaxseed in the morning.

Metallic taste from pine nuts (pine mouth)

Members of this reviewer’s family observed that everything tasted metallic after consuming a meal incorporating pine nuts. This well known phenomenon has currently no determined explanation but is possibly due to flavour contamination by insects during growth. Metallic taste disturbance, known as metallogeusia, is reported 1–3 days after ingestion, being worse on day 2 and lasting for up to 2 weeks. Cases were self-limited and resolve without treatment. The phenomenon apparently only occurs with Chinese product.
