A study was conducted to determine the effects of packaging materials, seasonality, storage temperature and time on physiochemical and antioxidant properties of roselle-mango juice blends. Roselle extract (20%, 40%, 60%, and 80%) was mixed with mango juice and stored in glass and plastic bottles at 4°C and 28°C. Total soluble solids, pH, titratable acidity, reducing sugar, color, vitamin C, tot...

In high frequency signal packaging, the plastic dielectric material takes on an increasingly important role in the performance of the signal transmission. Variations within the plastic can occur as a result of a number of manufacturing and environmental processes. These variations can be sufficient to change the dielectric properties. The extent of change to the dielectric properties of polymer...

BACKGROUND, AIM, AND SCOPE Food consumption is an important route of human exposure to endocrine-disrupting chemicals. So far, this has been demonstrated by exposure modeling or analytical identification of single substances in foodstuff (e.g., phthalates) and human body fluids (e.g., urine and blood). Since the research in this field is focused on few chemicals (and thus missing mixture effect...

In this study, the antimicrobial property and food package capability of polymethylpentene (PMP) substrate with silicon oxdie (SiOx) and organic silicon (SiCxHy) stacked layers deposited by an inductively coupled plasma chemical vapor deposition system were investigated. The experimental results show that the stacked pair number of SiOx/SiCxHy on PMP is limited to three pairs, beyond which the ...

      In order to ensure the safety of parenterals, international pharmacopoeias and national standards have set up stringent guidelines and standards. Particulate con- tamination is a potential health risk caused by intravenous injection of particles large enough to potentially clog the small arteries. Particles could be produced through manufacturing and packaging or even dispensing of the ph...

Hongmeiren is a high-quality orange fruit but susceptible to mechanical damage. This work proposes new packaging format (Packaging C), which used the plastic partition boards separate folding basket avoid fruits from crushing each other, and PU foam layer placed it along inside of EPE meet different sizes fruits. The results show that under both 3 10 h simulated transportation, Packaging C achi...

In this thesis, companies using returnable plastic packaging are investigated from a green logistics’ perspective, focusing on the washing process performed after they are used. Returnable plastic boxes used to carry components are, in some cases, washed systematically to secure customer requirements. The purpose of this master thesis is to describe existing flows of returnable plastic boxes by...

In 1976, a method of growing lettuce and other leafy vegetables on a floating raft of expanded plastic was developed independently by researchers at the University of Arizona and the University of Pisa in Italy. Today facilities exist in a number of countries including the United States, Japan and Canada. Termed “Deep Flow Hydroponics,” the system consists of horizontal, rectangular shaped tank...
