[ 1 ] - Effect of Echinophora platyloba DC. essential oil and lycopene on the stability of pasteurized cream obtained from cow milk
The present study was carried out to enhance shelf life of pasteurized cream using Echinophora platyloba essential oil (EEO) and lycopene. For this purpose, two concentrations of EEO (0.10% and 0.50%) and lycopene (20 and 50 ppm) alone and together as combinations were added in pasteurized creams and analyzed for microbial characteristics, sensorial properties and lipid stability durin...
[ 2 ] - Antibacterial activity of Enterococcus faecium derived from Koopeh cheese against Listeria monocytogenes in probiotic ultra-filtrated cheese
Viability of probiotic bacteria in food during maintenance and time of consuming in food has become a challenge in food hygiene and technology and is important for representing their beneficial health effects. The aim of this study was to determine the survival of probiotic Enterococcus faecium derived from Koopeh cheese added to industrial Iranian ultra-filtrated (UF) cheese and screening for ...
[ 3 ] - Validation of drop plate technique for bacterial enumeration by parametric and nonparametric tests
Drop plate technique has a priority and preference compared with the spread plate procedure, because of less time, quantity of media, effort requirement, little incubator space, and less labor intensive. The objective of this research was to compare the accuracy and fidelity of drop plate method vs. spread plate method by parametric and nonparametric statistical tests. For bacterial enumeration...
[ 4 ] - Biogenic amines determination in some traditional cheeses in West Azerbaijan province of Iran
Biogenic amines (BA) are nitrogenous compounds that possess biological activity. The source of production is the microbial decarboxylation of amino acids. This compounds are found in various types of cheese. The aim of this work was to evaluate the BA content of some traditional cheeses in West Azerbaijan province Iran. For this purpose, 70 samples of Koopeh, 10 samples of Lighvan and 5 samples...
[ 5 ] - Chemical composition and in vitro antibacterial activity of essential oil and methanol extract of Echinophora platyloba D.C against some of food-borne pathogenic bacteria
Echinophora Platyloba D.C as a medicinal plant is used for preservation of foods and treatment of many diseases in different regions of Iran. The present study was undertaken to determine the chemical composition and investigation of the antibacterial effects of essential oil as well as methanol extract from aerial part of Echinophora Platyloba D.C against S. aure...
[ 6 ] - جداسازی و شناسایی لاکتوباسیلوس ها در پنیرهای سنتی استان آذربایجان غربی
زمینه و اهداف: شناسایی فلور لاکتیکی طبیعی پنیرهای سنتی اولین گام در جهت توسعه آغازگرهایی است که در تولید پنیرهای صنعتی به کار می روند تا با استفاده از این آغازگرها ضمن حفظ منابع ژنتیکی بومی، فرآورده های صنعتی با بافت یکنواخت و دارای خصوصیات عطری و طعمی گسترده تر تولید گردد. شناسایی گونه های لاکتوباسیلوس جداسازی شده از پنیرهای سنتی استان آذربایجان غربی هدف مطالعه حاضر می باشد. مواد و روش کار: ت...
[ 7 ] - تأثیر پوشش کیتوزان غنی‌شده با لیکوپن بر پروفایل اسیدهای چرب و پارامترهای اکسیداسیون چربی فیله ماهی قزل‌آلای رنگین‌کمان در طول دوره نگهداری در یخچال (مقاله کامل تحقیقاتی)
ماهی مهم‌ترین منبع تغذیه‌ای اسیدهای چرب چند غیراشباع برای انسان می‌باشد. بنابراین، محافظت از ماهی در برابر انواع فساد اکسایشـی ضروری به‌نظر می‌رسد. لیکوپن، یک منبع آنتی‌اکسیدانی طبیعی می‌باشد. مطالعه حاضر به‌منظور بررسی خواص آنتی‌اکسیدانی لیکوپن ( با استفاده از روش دی‌پی‌پی‌اچ) و اثر ترکیبی دوزهای مختلف آن (5/1 و 3 درصد) و کیتوزان بر پارامترهای اکسیداسیون چربی و ترکیب اسیدهای چرب فیله ماهی قزل...
