Grape Seed Extract - A Natural Preservative
Quote:
Natural ingredient preserves meat quality in precooked supermarket offerings
Grape-seed extract is a viable natural alternative to synthetic ingredients that preserve meat quality in pre-cooked, frozen and refrigerated ready-to-eat meals, such as individual diet entrees or family-sized trays of frozen lasagna, according to a new University of Illinois study published in the Journal of Food Science.
�In the last five years, the section of the supermarket that contains fully cooked, ready-to-eat products has grown tremendously as consumer demand for convenience foods has increased. I�d estimate that 10 percent of all meals served at home feature these foods,� said Susan Brewer, a U of I professor of food science.
For years, the food industry has been using synthetic ingredients--BHA, BHT, and TBHQ--to preserve the quality of meats in precooked foods by slowing the oxidation of fats. But Brewer�s study shows that a natural product may be an even more effective antioxidant.
That product, grape-seed extract, is a byproduct of fermentation, and its efficacy is due mainly to its phenolic compounds, she said.
