pH effect on the physico-chemical, microstructural and sensorial properties of processed cheese manufactured with various starches

Processed cheeses containing 5% w/w potato, waxy maize or corn starch were manufactured in the pH range 4.5–6 to investigate the effect of pH on the physical and microstructural characteristics of high-starch processed cheese. Increased hydrogen bonding between the starch alcohol groups and hydrophilic protein residues was observed with both increasing and decreasing pH, indicating a higher degree of starch distribution. Optical microscopy showed a continuous starch exclusion network in cheeses manufactured with native starch between pH 4.8–5.3, with discrete starch particles present at increased and decreased pH. This network breakdown reduced product hardness and increased meltability, with the 5% starch cheese manufactured at pH 6 exhibiting higher sensory acceptability compared to the non pH modified sample. The present work demonstrates that increasing cheese pH during manufacture can reduce the negative physical characteristics associated with high-starch processed cheese and may provide industry with a cost effective method to increase the sensory acceptance of such products

A review on technological parameters and recent advances in the fortification of processed cheese

Background: Although the consumption of processed foods is growing in overseas markets, the increased awareness of consumers to health and wellbeing in recent years has led to a decline in the growth of processed food sales in the Western market. The added pressure on the food manufacturing industry to increase the perceived healthiness of processed foods has opened up new market potential in the area of fortified processed foods, such as processed cheeses. Scope and approach: This review paper provides an overview of the current methodologies into the production of a processed cheese with added health benefits, including the use of probiotics and prebiotics, vitamin and mineral fortification and the addition of plant macromolecules. Key findings and conclusions: Processed cheeses with increased health benefits have been of great interest to manufacturers, with reduced salt and reduced fat options commercially available. Although processed cheeses fortified with vitamins, mineral, probiotics and prebiotics are not as widespread, further work in these areas has been identified as a way to produce high value processed cheese products with added health benefits

On the uniqueness and global dynamics of AdS spacetimes

We study global aspects of complete, non-singular asymptotically locally AdS spacetimes solving the vacuum Einstein equations whose conformal infinity is an arbitrary globally stationary spacetime. It is proved that any such solution which is asymptotically stationary to the past and future is itself globally stationary. This gives certain rigidity or uniqueness results for exact AdS and related spacetimes.Comment: 18pp, significant revision of v

Uniqueness of the Trautman--Bondi mass

It is shown that the only functionals, within a natural class, which are monotonic in time for all solutions of the vacuum Einstein equations admitting a smooth ``piece'' of conformal null infinity Scri, are those depending on the metric only through a specific combination of the Bondi `mass aspect' and other next--to--leading order terms in the metric. Under the extra condition of passive BMS invariance, the unique such functional (up to a multiplicative factor) is the Trautman--Bondi energy. It is also shown that this energy remains well-defined for a wide class of `polyhomogeneous' metrics.Comment: latex, 33 page

Rupture uterus: a retrospective analytical study

Background: Over 500,000 women die each year due to complications of pregnancy and childbirth, a number that has remained relatively unchanged since 1990, when the first global estimates of the burden of maternal mortality were developed (WHO 2005). Objective of present study was to find out risk factors, management, related complications and associated maternal morbidity and mortality with rupture uterus.Methods: A retrospective analytical study was performed at Department of Obstetrics and Gynecology, PDU Medical College, Rajkot, Gujarat, India over a period of 3 years during 2014-2016. Evaluation of maternal age, parity, SE status, booking status, obstetric risk factors, duration of hospital stay, causes of rupture uterus, Management, intra-op and post-operative complications, maternal morbidity and mortality was done.Results: Total 29 cases of rupture uterus were found during study period. Most of them belong to age group of 21-30 (77.17%), Primipara (41.3%), Lower socioeconomic status (86.2%) and unbooked (65.52%) cases. Most common cause of rupture uterus was prolonged obstructed labor (51.72%) while scarred uterus (41.73%), transverse lie (3.44%) and injudicious use of oxytocin (3.44%) were others. In 16 cases obstetric Hysterectomy (55.17%) was performed while in 13 cases repair (44.82%) was done. We have found 2 cases of maternal death (6.89%) while study period with rupture uterus.Conclusions: Present retrospective analytical study has concluded that rupture uterus is a life threatening complication. Proper antenatal and intrapartum care, identification of high risk factors, promotion of skilled attendance at birth and institutional delivery are key factors in reduction and early diagnosis
