The microbiological quality of raw milk is key to the quality production of dairy products.

Alternation is a term that describes the change of composition, taste and smell at those points where it is inedible for the consumer. Microbial alternation of milk often involves degradation of proteins, carbohydrates and fats of organisms and their enzymes. Milk and dairy consumption has increased considerably in Kosovo over the last decade, and a large part of local productioncomes from small-scale distributors across the country. In this research, 50 milk samples weretaken at some of the cumulative sites and from dairy farms in three …

Indication Of Temperature And Time During Storage In Shelf Life Of Pasteurized Milk, By Using Response Surface Methodology, Alush Musaj, Përparim Birinxhiku, Bahtir Hyseni

UBT International Conference

Milk is a complex food product, with a high nutritional value. Milk produced from healthy cow is considered to be sterile, even though this is highly dependent on the environment of farm. Milk is processed to bring a cured with extend shelf life product. Pasteurization, is a curing process for milk based on thermal treatment, this process mostly inhibit the microbial growth but it does not destroy total microorganisms. Consequently, its shelf life is dependent on the storage parameter as temperature and time. Hence, the aim of our study was to analyze and prove indication of temperature and time by …

Determination Of Some Chemical Elements At Milk, At Three City In Macedonia (Kumanovo, Tetovo, Gostivar), Ilmije Vllasaku, Juliana Tomovska, Trajce Stafilov, Kemajl Kurteshi, Mirjana Menkovska

UBT International Conference

The aim of this research was to evaluate the possible contamination by heavy metals of milk from cows in Macedonia. The concentrations of heavy metals were determined in cow milk from the different farms, at three city (Kumanovo, Tetovo, Gotivar)in Macedonia. Each sample, homogenized and powdered, was mineralized in a microwave oven.

Quantitative analyses of Cd, Cr, Cu and Pb were performed using an atomic absorption spectrophotometer with graphite furnace; As was analyzed by hot vapor generation technique and Zn with the flame method.

The concentration of many metals is low (<0.1 mg/kg) such as: As,Co, Cd, Cr, Cu,Fe, Pb, and Zn.

Physico-Chemical And Microbiological Quality Changes In Cocoa And Whey Protein Enriched Functional Dairy Drink During Storage, H. R. Gupta, S. K. Kanawjia, M. K. Salooja, Prateek Sharma, Anil Kumar

Nutrition, Dietetics, and Food Sciences Faculty Publications

Cocoa and whey protein enriched functional dairy drink was subjected to storage studies at refrigeration temperature 4±1°C in the present study. The samples were studied for microbial and physicochemical tests during storage. The results in this study suggest that the product can be stored upto 18 days at 4±1°C. A decrease in pH from 7.01 to 6.49 for whey protein enriched product and from 6.94 to 6.41 in case of cocoa & whey protein enriched product was observed at the end of shelf life. The FFA increased from 0.72 to 1.46 meq./ml at the end of shelf life of 18 …

Storage Induced Changes In Sensory Characteristics And Viscosity Of Cocoa And Whey Protein Enriched Functional Dairy Drink, H. R. Gupta, S. K. Kanawjia, M. K. Saluja, Prateek Sharma

Nutrition, Dietetics, and Food Sciences Faculty Publications

The functional dairy drink product developed in the present study was packaged in LDPE pouches stored at refrigeration temperature 4±1°C. The results of storage studies depict that the product can be stored upto 18 days at 4±1°C without significantly affecting its sensory qualities. Overall acceptability scores decreased from initial 93.0 to 69.2 after 18 days of storage at 4±1°C for the drink enriched with whey protein; for the drink enriched with whey protein and cocoa, the scores decreased from 93.4 to 72.4. The consistency score of the product decreased from 27.5 to 19.5 for whey protein enhanced drink and from …

Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo

Honors Theses

Lactose intolerance is often blamed for the symptoms such as bloating, diarrhea, gas, abdominal pain, and nausea, that ail many people. Patients often do not seek proper diagnosis from a physician and create their own treatment plans, severely restricting lactose intake, without professional guidance. Even those who do seek the care of a physician find that diagnosis is complicated by less-than ideal testing and confusion due to the symptoms common to many other conditions. The misconceptions and inability to confirm a diagnosis of lactose intolerance can cause nutrient deficiencies in these patients, as well as begin a pattern of unnecessary …

Development Of A Rapid Detection And Quantification Method For Yeasts And Molds In Dairy Products, Brandon Nguyen

Department of Food Science and Technology: Dissertations, Theses, and Student Research

A rapid quantitative PCR (qPCR) method was developed for the detection and quantification of fungi that are potentially present in dairy commodities. Genes of interest that were considered and used in the method development were the following: 18S rRNA, actin, beta-tubulin, and elongation factor 1-alpha. The following organisms were screened in this method development: Galactomyces candidus, Debaryomyces hansenii, Yarrowia lipolytica, Penicillium roqueforti, Penicillium verrocosum and Cladosporium cladosporioides. The developed method has a standard curve based on the organism, Galactomyces candidus, and the primers based on the elongation factor 1-alpha gene. Using this yeast and …
