Sheep habit during hand milking, and relations between the incorrect hand milking procedure and mammary health
2023
This study aimed: (1) to evaluate the relation between the incorrect hand milking and mammary health; (2) to test the hypothesis of the ewe habit in the workstation, of their choice, during the milking. Teat moisturization with foam milk collected from the milk tank represents a high-risk factor because potentially contain mastitis-causing bacteria previously released from affected ewes. Moreover, it was found that sheep are routinary animals by habit during hand milking.
Effect of red wine soaking on the microbiological profile, total phenolic content and sensory aspects of an ovine pressed cheese
2022
The aim of this study was to produce an ovine pressed cheese with high polyphenol content. To this purpose, fresh Primosale Pecorino cheese was soaked for seven days in Nero d’Avola wine (NDW) and was indicated as experimental cheese production (EP). The final cheese was characterized for its microbiological, chemical and sensory characteristics. Specifically, cheese making was performed with pasteurized ewes’ milk and a commercial starter culture. Control cheese production (CP) did not include the soaking phase in NDW. Plate counts confirmed the dominance of the commercial starter until 109 CFU/g in both CP and EP cheeses. The soaking in NDW increased cheese total phenolic compounds (TPC) …
Leberfunktion von Ratten nach chronischer VerfÜtterung von90Sr
1966
Nach chronischer VerfUtterung von90Sr in Mengen von 140 und 350 pC/g Ca konnte bei Ratten eine leichte Beeintrachtigung der Ausscheidungsleistung der Leber im Bromsulfonphthalein-Test nachgewiesen werden. Diese Wirkung verstarkte sich mit Erhohung der zugefUhrten90Sr-Menge und mit Verlangerung der FUtterungsdauer. Da der Anstieg der Farbstoffretentionswerte in diesen Versuchen nur ein geringes Ausmas erreichte, wird somit wahrscheinlich gemacht, das durch eine sehr lang dauernde FUtterung von90Sr mit den hier gewahlten Dosierungen keine Leberschadigung ausgelost wird.
Enteral feeding policies for extremely low birth weight infants. A survey in 74 Italian neonatal intensive cAre units
1999
Background: Enterai feeding for infants with birth weight1000 g (ELBWI) is still a controversial issue. The aim of the present survey was to ascertain the attitudes of Italian neonatal intensive care units (NICUs) regarding this point. Method: A questionnaire, with multiple choice answers, regarding the timing of enteral feeding, its progression, the different techniques utilised, the eventual use of fortifiers and the interrupting criteria, was mailed to 92 Italian NICUs. Results: 74 NICUs all over the country participated in the study.1153 ELBWI were hospitalised in 1996 in these Units. Enterai feeding for babies between 501 g and 750 g is started on the 1st day of life in 23.3% of the NI…
La soluzione italiana alla crisi delle filiere agroalimentari: il decreto legge 19 marzo 2019, n. 27
2019
L’Autore affronta il tema della regolazione della filiera agroalimentare e dei tentativi di porre rimedio ai fallimenti del mercato . Analizzando i recenti interventi normativi in risposta alle gravi crisi del comparto lattiero-caseario, emergono difficoltà e incertezze del legislatore e del governo italiano nell’affrontare queste criticità, che sono legate all’assenza di un’adeguata regolazione di tipo contrattuale . Inadeguatezza che può essere affrontata e risolta puntando su di un mutamento di approccio e considerando che le relazioni contrattuali di filiera necessitano di interventi proporzionati, più efficaci ed efficienti, in grado di esaltare i momenti di autonomia contrattuale disc…
Evaluation of microbial diversity during the manufacture of Fior di Latte di Agerola, a traditional raw milk pasta-filata cheese of the Naples area
2006
Microbial diversity of the raw milk for the production of Fior di Latte di Agerola and its changes during cheesemaking were studied. Viable counts showed that at the end of curd ripening, loads of lactic acid bacteria, both mesophilic and thermophilic rods and cocci, higher than those commonly evidenced in similar cheeses produced by using natural or commercial starters, were detected. Identification of 272 isolates, supported by molecular diagnostic aids, evidenced representative cultures of a high number of bacterial taxa of interest as participating in the process, although most of the isolates belonged to Lactococcus lactis and Lactobacillus helveticus species. RAPD-PCR and REA-PFGE bio…
Fluorometric determination of chemically available lysine: adaptation, validation and application to different milk products.
2004
A spectrophotometric method based on the reaction between available lysine and ortho-phthaldialdehyde (OPA) was adapted and validated for fluorometric determination of the chemically available lysine contents in milk matrices (UHT and conventional in-bottle sterilized cow milk, milk-based infant formulas and infant formula ingredients). The values of the analytical parameters show its usefulness as a routine method (linearity, r = 0.9992; detection limit, 0.0066 mg/mL assay; accuracy, 99-108%; precision, intra-day 2.1-5.9% and inter-day 3.5 10.2%). No statistically significant differences (p < 0.05) were found between the values obtained with the adapted method and those obtained applying t…
Selected lactic acid bacteria as a hurdle to the microbial spoilage of cheese: Application on a traditional raw ewes' milk cheese
2013
To evaluate the efficacy of lactic acid bacteria (LAB) to improve the hygienic safety of a traditional raw milk cheese, the raw ewes’ milk protected denomination of origin (PDO) Pecorino Siciliano cheese was used as a model system. Different Pecorino Siciliano curds and cheeses were used as sources of autochthonous LAB subsequently used as starter and non-starter LAB. These were screened for their acidification capacity and autolysis. Starter LAB showing the best performance were genotypically differentiated and identified: two strains of Lactococcus lactis subsp. lactis were selected. From the nonstarter LAB, Enterococcus faecalis, Lactococcus garvieae and Streptococcus macedonicus strains…
ATR-FTIR spectroscopy for the routine quality control of exosome isolations
2021
Abstract Exosomes are nanosized vesicles containing specific cargos of DNA, RNA, proteins, metabolites, and intracellular and membrane lipids. Exosome isolation needs to be optimized carefully depending on the type of biofluid and tissue and the retrieved exosomes need to be characterized. The main objective of this study was to determine the feasibility of a multimodal analysis of Attenuated Total Reflectance – Fourier Transform Infrared (ATR-FTIR) spectroscopy and UPLC–QqTOF-MSMS for the development of a routine quality control tool of isolated exosomes and the rapid characterization of their lipid profiles and total protein content. Using human milk as model example, exosomes were isolat…
Assessing the carbon footprint across the supply chain: Cow milk vs soy drink
2022
Abstract Since livestock product consumption could have a significant effect on tackling climate change, in the few last years, there has been an increasing consumer demand for non-dairy alternatives. Despite plant-based beverages being considered crucial to foster the transition towards sustainable diet models, no studies have yet compared the level of emissions of plant-based beverages with animal-based ones. The present study aims at computing the carbon footprint of cow milk and that of soy drink and evaluating the carbon footprint results in the light of the substitutability of cow's milk with soy drink, analyzing the potential environmental, economic and nutritional trade-offs between…
