Application of rosemary and its extracts in food preservation

Rosemary is a species of Lamiaceae rosemary, native to the Mediterranean coast

Studies have confirmed that rosemary is rich in carnosic acid, carnosol, rosmarinol, rosmarinic acid and other polyphenols, and has a variety of physiological active functions

Application of rosemary extract in oil The unsaturated fatty acid in oil is easily oxidized during processing and storage, which significantly reduces its nutritional value and sensory quality

At present, adding antioxidants is one of the effective measures to prevent oil oxidation

In addition to effectively inhibiting oil oxidation, rosemary extract can also effectively improve the quality of fried food

The application of rosemary extract in the preservation of meat products has the characteristics of high fat content and rich nutrition, and meat products are prone to oxidation and microbial contamination during processing and storage, which not only causes the reduction of product nutrition and sensory quality, but also reduces the quality of meat products.

Relevant studies in recent years have confirmed that the addition of rosemary powder, extract or essential oil can effectively inhibit the formation of lipid oxidation products such as thiobarbituric acid reactants and hexanal during storage of meat and meat products.

In addition, rosemary extract can inhibit the growth and reproduction of pathogenic bacteria and decay-causing bacteria on the surface of meat products, and can enhance the preservation effect when used in combination with other processing technologies

Application of rosemary extract in the processing and preservation of aquatic products Due to high protein content, high moisture content, rich in unsaturated fatty acids and other reasons, aquatic products are easily contaminated by microorganisms during storage, transportation, processing and sales, causing spoilage.

Studies have confirmed that the use of rosemary extract, rosemary essential oil, etc.

In addition, rosemary essential oil is also used in the preparation of food packaging films, especially edible films, and it has been confirmed that it has a good preservative and fresh-keeping effect on aquatic products

Rosemary and its extracts are also widely used in the preservation of fruit and vegetable raw materials, cheese, fresh flour products,
