the present study examined the effect of packaging film on the quantitative and qualitative properties of button mushrooms. the three types of packaging tested were a clear polyvinyl chloride box, polyvinyl chloride stretch film and biaxially-oriented polypropylene film (bopp). the five types of moisture absorbers examined were silica gel (2.5 g, 1.25 g), sodium chloride (2.5 g, 1.25 g), and si...

introduction: pharmaceutical companies as well as food and cosmetics manufacturers are legally required to provide a shelf-life label on their products packaging as part of their stability study report. there are different recommended software like r software package and sas which can perform as shelf-life estimating tools for analyzing the data achieved by the stability testing of drugs and va...

infant formula has a fatty acid composition that meets the needs of the neonates for unsaturated fatty acids.these fatty acids are of major importance during this period of life in which the brain and retina are developing, and will therefore have an influence upon visual acuity and learning abilities. oxygen reacts readily with unsaturated fatty acids, so that every time these compounds are ha...

abstract sour cherry (prunus cerasus l.) is an important iranian-native fruit, considered highly perishable commodity which cannot be stored for any length of time. on this study, effect of three gas compositions (ambient, 5% o2+5% co2+90% n2 and 10% o2+15% co2+75% n2) and two storage temperatures (0 and 5 °c) on two sour cherry cultivars namely erdy jubileum and erdy botermo was studied in a c...

using titanium dioxide nano-silver packaging, which is antibacterial and resistance to the diffusion of gases such as oxygen, is increasing in food industry. therefore, we compared the effect of titanium dioxide-based nano-silver packaging and conventional polyethylene packaging on the fungal flora of consuming bread in order to increase the shelf-life storage of consuming bread. one hundred fo...

The shelf-life of a drug product is the time that the average drug characteristic (e.g., potency) remains within an approved specification after manufacture. The United States Food and Drug Administration (FDA) requires indication for every drug product of a shelf-life on the immediate container label. Since the true shelf-life of a drug product is typically unknown, it has to be estimated base...

Abstract Food occupies a principal role in human life, having major impact on health status and representing diverse characteristics that ensure valuable nutrient intake. Ensuring nutrition has become one of the essential problems facing mankind, quantity, quality proper use food have effect body. Many raw materials products spoil easily, considerably shortening their shelf life. Extending shel...

Adding supplements to hen feed can increase egg nutritional value. Astaxanthin, tocotrienols, and tocopherols are potent antioxidants that provide health benefits to humans. We hypothesized that the addition of these nutrients to hen feed would result in an increased nutrient content in egg yolk with minimum changes in functional properties. Laying hens (Hy-Line W-36 breed) were fed four diets ...

As egg is a primary source of high quality proteins and offers a balanced distribution of basic food constituents such as minerals (iron, calcium, phosphorus and potassium) and vitamins, particularly vitamin E, A, B12, B2 and folic acid alongside high amounts of lipids, such as triacylglycerols, phospholipids and cholesterol to the body. Eggs were spray dried, that ultimately increase the shelf...

The transformation of shell eggs into safe liquid, frozen or spray-dried egg white with extended shelf life requires many technological operations that result in modifications to the egg white’s functional properties. During these processes, shear rates underwent by egg white may be responsible for part of the loss of its functional properties. The present study was aimed at measuring the effec...
