Evaluation of electrostatic powder coating method to prolong the shelf life of cheese slices.

Electrostatic coating is being developed as an attractive alternative to overcome the problems encountered during conventional coating which includes non-uniform coating, dust generation, high energy and time consuming, equipment cleaning, and operating expenses. In this method, powder particles are charged by passing through an ion-rich region, which repel each other to produce an evenly distributed coating. This results in a uniform distribution of powder on target surface.

Role of fruits in aging and age-related disorders.

Aging is a collection of changes that contribute to decline in maximum function and ultimately death of an organism. This process is controlled and initiated by several mechanisms including telomere shortening, oxidative stress, AMP-activated protein kinase and sirt-1. Several therapies have been reported to relieve the process of aging.

Antibiotics, Acid and Heat Tolerance of Honey adapted , Typhi and .

The medicinal importance of honey has been known for many decades due to its antimicrobial properties against life-threatening bacteria. However, previous studies revealed that microorganisms are able to develop adaptations after continuous exposure to antimicrobial compounds. The present study was conducted to explore the impact of subinhibitory concentrations of branded honey (Marhaba) and unbranded honey (extracted from plant) locally available in Pakistan on ATCC 10536, Typhi and by investigating the development of self- or cross-resistance to antibiotics (gentamicin, kanamycin and imipenem).

Physicochemical, Sensorial and Microbiological Characterization of PoroCheese, an Artisanal Mexican Cheese Made from Raw Milk.

Poro cheese is a regional product originally from the area of Los Rios, Tabasco in Mexico.
