Designing the pH-sensitive indicator based on starch nanoparticle with bromocresol green for monitoring meat spoilage.

The starch nanoparticle, combined with bromocresol green (BCG), served as a pH-sensitive indicator to monitor meat quality throughout an 8-day refrigerated storage period. The meat samples were sealed in package which the pH-sensitive indicator attached to the interior part of packaging lid. The changes in meat quality were evaluated by total volatile base nitrogen (TVBN), pH, total viable count (TVC), sensory analysis, and color in interval of 0, 3, 5, 7, and 8-days storage at 4°C.

The regular intake of (goji berry) is supposed to play an important role in the promotion of human health. Regarding, its incorporation into staple foods, including bread, seems to be effective. However, it requires the evaluation of dough behavior and final product quality.

Determination of aflatoxin M and ochratoxin A in breast milk in rural centers of Yazd, Iran: Exposure assessment and risk characterization.

Breast milk (BM) is considered as the best source of nutrition which could have prevention effects on various diseases in the first years of a child. Along with nutritive compounds, presence of contaminants such as mycotoxins in BM could be transmitted into neonate. The aim of this study was to determine the occurrence, levels, and factors associated with the presence of aflatoxin M (AFM) and ocratoxin a (OTA) in BM samples of nursing mothers in rural centers of Yazd, Iran.

Quinoa dough fermentation by and lactic acid bacteria: Changes in saponin, phytic acid content, and antioxidant capacity.

The effects of two fermentation processes (common fermentation with and fermentation by subsp. PTCC 1608 and subsp. PTCC 1745) on pH, titratable acidity, total phenolic and flavonoid contents, antioxidant capacity, saponin content, as well as phytic acid content of quinoa dough were investigated during the 24-h fermentation (4-h interval).

Bisphenol A release from food and beverage containers - A review.

Dietary exposure was introduced as the primary way Bisphenol A (BPA) enters the human body. Although significant efforts have been made to analyze BPA's presence in different foodstuffs, less attention has been given to introducing the conditions that facilitate BPA release. This review aimed to mention possible factors affecting BPA release into foods and beverages.

Concentration of mineral and heavy metals in raw mare (horse) milk consumed in Yazd, Iran: A risk assessment study.

Background: In recent years, the mare's milk has been introduced as a rich source of nutrients with hypoallergic characteristics which is widely used for Iranian infants.

Objectives: The present study aimed to investigate the heavy metal concentration of mare's milk and its consumption risk assessment.

Methods: About 88 mare's milk was collected from Yazd, the centre of Iran, during the summer of 2020.

Zika virus as an emerging arbovirus of international public health concern.

Zika virus (ZIKV) was identified in 1947 in a rhesus monkey during an investigation of the yellow fever virus in the Zika Forest of Uganda; it was also isolated later from humans in Nigeria. The main distribution areas of ZIKV were the African mainland and South-East Asia in the 1980s, Micronesia in 2007, and more recently the Americas in 2014. ZIKV belongs to the Flaviviridae family and Flavivirus genus.

The chemical composition and heavy metal content of sesame oil produced by different methods: A risk assessment study.

The oil was extracted from sesame seed with two extraction methods. Traditional (Ardeh oil) and industrial method (cold pressing method: virgin and refined sesame oil) oil extraction was studied to compare the quality and heavy metal content of extracted oils. The chemical properties (fatty acid composition, peroxide, anisidine, acid values, and TOTOX) and heavy metal contents were investigated.

Application of essential oil of Gum, polypropylene and silica nanoparticles as a new milk packaging.

The aim of current study was to investigate the antimicrobial effect of gum essential oil of (wild pistachio) tree (GEO) and design a new film based on polypropylene polymer coated with silica nanoparticles and GEO. The antimicrobial activity of the packaging film was evaluated with or without milk on , , , and during 35 days. The results showed that GEO has significant antibacterial properties.

Evaluation of heavy metal concentration in imported black tea in Iran and consumer risk assessments.

Tea grows in the contaminated soils, absorbs the heavy metals, and enters them into the human food chain. The concentrations of Pb, Cd, Cu, As, and Hg of the imported black tea leaves to Hormozgan Province were evaluated by atomic absorption spectrometer. Then, the Hazard Quotient (HQ) and Hazard Index (HI) levels of heavy metal intakes were calculated to estimate the health hazard for consumers.

Prevalence and genotyping identification of Cryptosporidium in adult ruminants in central Iran.

Background: Apicomplexan parasites of the genus Cryptosporidium infect a wide range of animal species as well as humans. Cryptosporidium spp. can cause life threatening diarrhea especially in young animals, children, immunocompromised patients and malnourished individuals.

Molecular typing of Giardia duodenalis in cattle, sheep and goats in an arid area of central Iran.

Giardia duodenalis is one of the most common intestinal parasites in humans as well as livestock and wildlife. It is of both public and veterinary health importance in developing nations. A molecular survey of Giardia duodenalis assemblages in ruminants from Yazd Province, Iran was conducted on 484 animal faecal samples collected per rectum from slaughtered ruminants including 192 cattle, 192 sheep and 100 goats from June to November 2017.

The effect of Zataria multiflora Boiss Essential oil on the growth and citrinin production of Penicillium citrinum in culture media and cheese.

The effect of Zataria multiflora Boiss Essential oil (EO) on the growth, spore production, and citrinin production of Penicellium citrinum PTCC 5304 in the culture media as well as Iranian ultra-filtered white cheese in brine was investigated. Radial growth and spore production on the potato dextrose agar (PDA) were effectively inhibited by EO in a dose-dependent manner. At 200 ppm, the radial growth and sporulation declined by 92% and 100%, respectively.
