Effect Of Hot Water Conditioning On Microbial Safety And Quality Of In-Shell Pecans, Karuna Kharel

LSU Master's Theses

Hot water conditioning of in-shell pecans is one common practice followed by industries to facilitate shelling. It also acts as a preventive control for potential microbiological contamination that might occur during pre- and post-harvest processes. However, heat treatment may have an effect on the eating quality of nuts. The main objectives of the study were to develop a post-harvest hot water treatment intervention as a kill step to destroy foodborne pathogens on in-shell pecans and evaluate the effect of treatments on physicochemical properties, consumer acceptance and purchase intent of dehulled and roasted pecans. The time (1-5 min) and temperature (70, …

Heat, Acid And Osmotic Stress Tolerance Of Leuconostoc Mesenteroides As Influenced By Prior Exposure To Various Mild Stress Conditions, Ingrid C. Osorio Rodriguez

LSU Master's Theses

The importance of Leuconostoc mesenteroides is recognized for its contribution to taste in cultured dairy products. It has been cited for its potential role as a probiotic. Consumer demand exists for new dairy products with health benefits. In the manufacture of probiotic-products survival of Leuconostoc mesenteroides would depend on its ability to tolerate challenging processing and storage conditions. Improved viability by prior exposure to mild stresses can increase stress tolerance toward a more severe stress. Furthermore, it can result in cross-protection due to connection of several proteins in response to stresses. Objective was to evaluate the effect of prior …

Hybrid Extended Kalman Filtering And Noise Statistics Optimization For Produce Wash State Estimation, Vahid Azimi, Daniel Munther, Seyed Abolfazl Fakoorian, Thang Tien Nguyen, Daniel J. Simon

Mathematics and Statistics Faculty Publications

Food-borne diseases associated with fresh produce consistently cause serious public health issues. Although sanitization measures are utilized to enhance the safety of fresh produce, strategies that neglect the dynamic nature of commercial wash processes are limited, creating the potential for pathogen cross-contamination and major disease outbreaks. In light of this risk, there is an urgent need for new control approaches during produce washing to reduce the probability of outbreaks. As an important step in this direction, a hybrid extended Kalman filter (HEKF) and particle swarm optimization (PSO)-based noise statistics optimization are designed for a produce wash system. The HEKF uses …

Interaction Of Cocoa Powder With Intestinal Microbiota, Martha M. Escoto Sabillon

LSU Master's Theses

Cocoa is the fully fermented and dried seed of the cacao tree (Theobroma cacao L.) which has prebiotic properties, due to their high concentration of polyphenols. Therefore, the ingestion of cocoa could cause changes in the proportions of the intestinal microbiota that can influence the intestinal immune response. The objective of this study was to determine the effect of alkalization process of the cocoa bean in the diversity of the gut microbiota. The samples were “lavado” unprocessed cocoa powder, “natural” unprocessed cocoa powder, “D-11-S” as alkalized cocoa powder, “D-11-B” heavily alkalized cocoa powder, and raw cocoa “shells” and a control …

Physico-Chemical Properties Of Ginger Oil, Bee Wax And Black Seeds, Qëndresa Istrefi, Rina Krasniqi, Arleta Rifati-Nixha, Kaltrina Kastrati, Fatjonë Krasniqi, Enver Përzhaku

UBT International Conference

We investigated to emphasize the physico-chemical properties of these three compounds: ginger oil, bee wax and black butter oil. After the determination we have come to the conclusion that for the ginger oil the values of the acid number, iodine number, soap and ester number have not changed from the standard values that are allowed. Therefore we conclude that this oil is healthy to be used in our daily diets. The bee wax after undergoing the necessary testing has showed that these chemical values, iodine number, soap and ester number have been deviated from the allowed standard values. However the …

Genealogical Analysis Of Bar’S Body Activity In Hemophilia At Two Brothers And A Cousin, Naser Kamberi

UBT International Conference

In this study it is included a sample of the Presevo population and villages of 3771 individuals. During family interviews, we encountered cases in women with hemophilia and hemophiliacs. Predicting that X-sex chromosome is inactive we did not have the case that females are hemophilic. By doing the genealogical analysis of these families, we will present the thoughts about the role of Bari's body when it comes to hemophilia. The genealogical method can be used especially effective in cases of monogenic inheritance. From the cases encountered during the hearing, we did not have any hemophilia in female gender. Considering that …

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 …

UBT International Conference

Beer production passes through those steps: malting, worth production, fermentation, and filtration. Filtration is used to remove yeast, proteins and other unwanted substances. Filtration is carried out by candle filters with kieselguhr, diatomaceous earth in a form of silica. In this study there are used three types of kieselguhr (DIF, CBL, and CBL3). There are used different kieselguhr quantities for the same beer volume and is measured filtration time, turbidity and beer color. Experiments showed that a good filtration is ensured by using all three types of kieselguhr. It is important to set a sufficient first layer from 800 to …

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.

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 …
