Olive Powder and Its Health Benefits
Olive powder can serve as a safe alternative to animal-derived fillers found in health foods and pet food products, while also acting as a thickener and texturizer for gluten-free flours.
Studies showed that adding 2% olive cake powder to gluten-free breadsticks dramatically reduced E. coli levels and carcinogenic amines while simultaneously improving their sensorial properties.
Early Life and Education
Olive leaves may go underrated, but they contain many powerful health-promoting qualities that should not be overlooked. Packed with polyphenol oleuropein known for its anti-inflammatory and anti-ageing benefits; protect against cardiovascular diseases by lowering blood pressure; inhibits LDL oxidation associated with heart disease – these benefits make olive leaves one of our greatest hidden gems!
Studies have demonstrated the power of olive leaves to strengthen immunity, lower inflammation levels and fight free radical formation. They may even help protect rats against nonalcoholic steatohepatitis (NASH).
Researchers investigated traditional and innovative extraction methods in order to produce extracts with high purity and bioactivity, with ultrasound-assisted extraction proving especially fruitful in this regard. For instance, ultrasound assisted extraction was successfully used to enrich an Italian cereal-based food known as taralli while the polyphenol content of its contents were measured before and after addition.
Olive powder is a product derived from semi-defatted and de-stoned olives that has been semi-defatted, de-stoned, and contains high concentrations of natural nutraceutically active compounds such as oleic acid, polyphenols, and tocopherols that offer many health benefits.
Research Chemist Mendel Friedman packed E. coli O157:H7 into ground beef patties before mixing in various plant extracts such as olive powder, lemongrass oil and basil extract to cook at 160 degrees Fahrenheit for optimal results. Olive powder proved most successful at decreasing pathogen levels while lemongrass oil followed closely behind followed by basil extract.
Muniz and Price then accepted the challenge of opening and running their own specialty shop, Outrageous Olive Oils & Vinegars. Their high-end selection made Outrageous a popular destination on the west coast for purchasing premium oils and vinegars; however, due to a new baby on the way in 2019, Muniz and Price decided to sell Outrageous.
Achievement and Honors
She serves as a judge at the renowned Olive D’Or competition and has won multiple awards for her efforts. Additionally, she offers black olive powder made from Kalamata olives that she sells as an alternative source of salt in food products.
OMW contains many beneficial phenolic compounds with antioxidant and antimicrobial activities, making OMW one of its greatest assets. Unfortunately, realizing its full value can be challenging given its structural diversity.
The authors present a new approach involving fractionation and spray drying of OMW to reduce energy consumption and waste production, with solid fractions produced through screening being utilized as replacement salt in foods while liquid fractions can serve as organic fertilizer sources.
Olive oil has long been recognized for its ability to lower the risk of heart disease and other age-related conditions, thanks to oleuropein, a polyphenol with powerful antioxidant properties.
Researchers have explored various techniques for extracting phenolic compounds from olive leaves, such as solvent extraction (Soxhlet extraction, maceration and hydro-distillation) and thermal processing. While results of each have varied, each can be tailored to meet varying extraction needs.
This ingredient comes as either an extract or capsule and can be easily integrated into a wide variety of food products, helping improve their functional qualities and increasing shelf life while at the same time offering consumers a way to add olive flavor without jeopardizing their high phenolic content.
OLEAF4VALUE project’s focus is to convert all remaining residue into valuable products and commercial uses for those found. Olive leaves contain antioxidants, anti-inflammatories and antimicrobials – yet only 0.2% find commercial application worldwide.
Liquid fraction offers the greatest potential for energy applications, while pulp and stone fractions could be used to produce food ingredients, particularly pulp with its high concentration of phenolic compounds (e.g. hydroxytyrosol) bound to fiber.
Dynamic processing, which accounts for the chemical composition of each batch of leaves, enables extraction of various chemicals. If leaves contain high levels of oleuropein, for instance, they could be processed specifically to extract that compound. Chlorophyll absorbance values were similarly found between rosemary powder and olive oil after conventional maceration and ultrasound maceration maceration; suggesting it can act as an indicator for organic compounds present.
