BACKGROUND Preservative effect of melanin-free extract of Sepia esculenta ink (MFESI) on Sparus latus fillet has been verified in our previous work. This study aims to further approach the mechanism of MFESI for extending the shelf-life of fish fillet during cold storage. Tilapia fillets were treated with different dosage of MFESI (0, 15, 25 and 35 mg/ml) and packed with preservative film for s...

Pyramid has been variously studied for its mystical preservative, healing and curative effects. The power of the pyramids has been much talked about in Egypt and the great pyramids as the wonders of the world. They are mentioned as çikhariëis and gopurams used in temples in Indian tradition. It is associated with Chakras and the elevation of the human mind to the super-consciousness levels. Alt...

Background: Control of fungi is problematic, since effective methods for intervening fungal infection or contamination, especially for those resistant to drugs/fungicides, are often very limited. Generally regarded as safe (GRAS) agents, such as natural compounds or their structural analogs could be potential sources of sustainable antifungal agents. As a proof of concept, antifungal efficacy o...

A universal diluting fluid (UDF) was developed for use in membrane filtration sterility testing. Diuting fluid is used to free the filter membrane of preservative residues which could inhibit microbial recovery. Current procedures employ one of several fluids described by the United States Pharmacopeia. UF was designed to utilize the neutralizing capabilities of a combination of inactivating ag...

Antimicrobial packaging is an important form of active packaging that can release antimicrobial substances for enhancing the quality and safety of food during extended storage. It is in response to consumers demand for preservative-free food as well as more natural, disposable, biodegradable, and recyclable food-packaging materials. The potential of a combination of allyl isothiocyanate and pot...

Microbial safety of food products is often accomplished by the formulation of food-grade preservatives into the product. Because of the growing consumer demand for natural substances (including preservatives) in the composition of consumed foods, there is also a growing interest in the natural antimicrobial nisin, which has generally recognized as safe (GRAS) status for certain applications. Du...

Introduction: In this study, the chemical composition and antimicrobial activity of essential oil of Ziziphora clinopodiodes and its potential application as a natural preservative in reducing the indigenous microbial population of hamburger were investigated. Method: Essential oil of Ziziphora clinopodiodes cultivated in Iran was obtained by Hydro-distillation method (HDM). Chemical compositio...
