هدف : تعیین میزان آفلاتوکسین M1 در شیرهای UHT. طرح : مطالعه مقطعی. روش : در این مطالعه تعداد 64 نمونه از شیرهای UHT عرضه شده در تهران به طور تصادفی انتخاب گردید و نمونههای مذکور از نظر میزان آفلاتوکسین M1 با روش TLC مورد بررسی قرار گرفتند. تجزیه و تحلیل آماری: با استفاده از روش آنالیز واریانس یکطرفه به منظور یافتن اختلاف احتمالی بین فصول مختلف سال نتایج مورد تجزیه و تحلیل قرار گرفت. نتایج ...
In this study measurements of color parameters of UHT milk were performed, by using a MOM-color 100 photoelectric tristimulus colorimeter. Colors of UHT milk samples containing 3.2% and 1.6% milk fat, processed under industrial conditions, packed in polyethylene terephtalate (PET) based packages, and stored for 0, 15, 30, 45, 60 and 90 days at ambient temperature (20±5°C) were examined. Results...
Ultra High Temperature (UHT) processing leads to the formation of "cooked" and "flat" flavors in milk. These undesirable notes occur due to the volatile formation of a variety of sulphur containing compounds, methyl ketones and aliphatic aldehydes, derived from the constituents of the milk's matrix during thermal processing and storage. The "cooked" flavor of UHT milk is associated with the pre...
5 Present study attempted to determine the microbiological quality of raw, pasteurized and UHT (Ultra High Temperature-processed) milk samples collected from different locations in Bangladesh. A total of 46 samples were studied including 22 raw milk samples from the local dairy markets and 24 different brands of pasteurized and ultrahigh temperature (UHT) treated milk manufactured in different ...
The development of alternative microbiological techniques is driven by the necessity to meet the current needs to deliver rapid results in the manufacturing process of foods, but it is important that these methods be evaluated for each application. The objective of the present study was to assess the Petrifilm™ EB and the TEMPO(®) EB systems with ISO 21528-2:2004 for the count of Enterobacteria...
The melanophores of larval Xenopus laevis are disparately distributed on the hypomere in that the upper region (UHT) is densely pigmented, the median region (MHT) is moderately pigmented, and the lower region (LHT) is unpigmented. The roles of the melanoblasts and their tissue environment in determining the melanophore pattern was investigated by heterotopic transplantation of hypomeric tissues...
تشخیص آلودگی میکروبی شیر، بهعنوان مهمترین شاخص کیفیت شیر در صنایع لبنی، بهکمک روشهای نوین مهندسی اهمیت زیادی دارد. در تحقیق حاضر، آلودگی میکروبی پاکتهای شیر UHT با استفاده از حسگرهای فراصوتی تشخیص داده شد. پاکتها بهصورت مصنوعی در چهار رقت متفاوت و با سه تکرار به باکتری E. coliآلوده شدند. فرکانس مرکزی سنسورهای پیزوالکتریک MHz 02/1 بود و با ولتاژ پیک V 5/18 استفاده شدند. برای پایش مشخصهه...

Aseptic ultra-high-temperature (UHT)-type processed food products (e.g., milk or soup) are ready to eat products which are consumed extensively globally due to a combination of their comparative high quality and long shelf life, with no cold chain or other preservation requirements. Due to the inherent microbial vulnerability of aseptic-UHT product formulations, the safety and stability-related...
Article history: Received 15 August 2016 Accepted 2 September 2016 Available online 7 September 2016 blood pressure control. The aim of this prospective study was to compare the magnitude of the effects on renal function and blood pressure control in CKD and non-CKD patients with controlled hypertension (CHT) vs. uncontrolled hypertension (UHT). We conducted a prospective, longitudinal study of...
