Microbiological Spoilage of Dairy Products
The wide array of available dairy foods challenges the microbiologist, engineer, and technologist to find the best ways to prevent the entry of microorganisms, destroy those that do get in along with their enzymes, and prevent the growth and activities of those that escape processing treatments. Troublesome spoilage microorganisms include aerobic psychrotrophic Gram-negative bacteria, yeasts, m...
متن کاملMicrobiological quality of commercial dairy products
The purpose of this research was to assess the hygienic properties of commercially available dairy foods. The products surveyed included liquid milks (pasteurized and UHT-treated), cultured dairy products (kefir, cultured buttermilk, sour cream, yogurt, probiotic fermented milks), cheeses (quarg products, soft, semi-hard, hard, and extra hard cheeses made from bovine, caprine, and ovine milk), ...

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولStreamlined analysis of lactose-free dairy products.
Functional food for lactose-intolerant consumers and its global prevalence has created a large market for commercially available lactose-free food products. The simplest approach for detection and quantitation of lactose in lactose-free dairy products was developed. A one-step sample preparation was employed and the resulting 10% sample solution was directly subjected to the chromatographic sys...
متن کاملImproved microbiological assay procedures for dihydrostreptomycin residues in milk and dairy products.
Because dihydrostreptomycin can remain as a slowly removed antibiotic residue in dairy animals and because of the need for more sensitive procedures with which to provide information concerning antibiotic residues in food products, procedures were developed in more sensitive assays of dihydrostreptomycin in milk and some representative dairy products. The cleanup procedures that aided these imp...
