fruit leather is one of dried product with variable production, good marketing and popular consumption in many countries of the world. in this research, the effect of concentration temperature (55-75 °c) and time (20-40 min) and drying temperature (40-70 °c) on the chemical composition (brix, ph, sugars and vitamin c) and the microbial properties of apple leather investigated. the results showe...

Background: Edible films and coatings have potential benefits for food packaging, particularly meat products. These coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. In this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of  5 days was...

detecting microbial contamination of milk using novel engineering techniques is very worthy. in current study, microbial contamination of uht milk packages was detected using ultrasonic sensors. milk packages artificially were inoculated to e. coli in four dilutions and three replications. monitoring of ultrasonic properties was performed by measuring amplitude and time delay factors. artificia...

Background: Many common cancers, such as prostate, breast, and colon, are caused by harmful substances and compounds contained in processed foods, including nitrite-treated meats. The aim of this study was to investigate the possibility of replacing sodium nitrite with Monascus purpureus pigment in sausage and to assess its antimicrobial, antioxidant, color, and sensory properties. Methods: The...

background: sohan is an iranian traditional brittle confection which its ingredients are susceptible to oxidation and microbial contamination during storage. this experimental study was designed to determine the effect of damask rose (rosa damascena mill.) extract on some chemical, microbial, and sensory properties of sohan during storage at 25 °c. methods: the sohan ingredients were mixed, bak...

soil enzyme activities are considered as one of the most important biological indicators and reflect the soil quality and fertility. current study was conducted to investigate the relationship between urease, invertase, alkaline phosphatase and aryl sulphatase activities of two histosols (located in kerman and shahrekord provence) and some of the soil chemical and biological properties. soil sa...

Reflected differential interference contrast microscopy and attenuated total reflection Fourier transform infrared spectroscopy were used to obtain complementary data on the structural and chemical properties of a biofilm. This information was obtained nondestructively, quasisimultaneously, and in real time, thereby permitting the verification of time-dependent relationships between the biofilm...
