Food and Machinery
An efficient microwave assisted extraction procedure for the lignans from the leaves of Cinnamomum camphora was investigated and optimized. Response surface methodology (RSM) based on a three-level four-factor Box Behnken Design (BBD) was employed to optimize the extraction conditions. The best extraction conditions were as follows: microwave time 5 min, ratio of material to ethanol 1∶26 (g/mL), ethanol concentration 80%, microwave temperature 60 ℃. Under the optimization conditions, the experimental yield of lignans was 42.69%, which was well matched with the predictive yield of 42.95%.

Reducing Food And Packaging Waste Through Developing Edible Fruit Based Packaging Prototypes, Melanie Thatcher
Materials Engineering
Packaging is used to contain, preserve, protect, and advertise both manufactured and natural products. In 2013 it was reported that over thirty percent of solid waste in the United States was from packaging. One way to reduce the impact of packaging on the environment is to create a solution that is edible and sourced from a waste or secondary food product that is not currently being utilized. Food-contact packaging made from recycled materials must meet strict U.S. Food and Drug Administration (FDA) regulations to be utilized as raw material for packaging. Fruit pomace is a candidate material since it may …

The Use Of Lactic Acid Bacteria To Control The Growth Of Foodborne Pathogens On Fresh-Cut Fruits And Sprout Vegetables, Franca Gabriela Rossi
Master's Theses
Growing consumer awareness of the health benefits associated with fruits and vegetables and demand for easy to prepare products has prompted the development of a wide variety of minimally processed fruits and vegetables. Minimally processed fruits and vegetables are often peeled, cut, or diced which compromise the produces’ natural protective barriers, exposing a nutrient rich medium and providing an ideal environment for the growth of microorganisms, including foodborne pathogens. The germination conditions of sprout vegetables consisting of relatively high temperatures and humidity, low light and abundance of nutrients are also conducive to the proliferation of foodborne pathogens. Recent outbreaks and …

The resistant starch (RS) in enzymatic branch-chain elongated waxy corn starch (WCS) was separated by using in vitro digestion method. Then, the physicochemical properties and molecular structure of RS were characterized. The results showed that the morphology of starch was significantly changed after digestion, and irregular cracks appeared on the surface of RS. Moreover, the improvement of thermal stabilities of RS wasalso observed. These results revealed that the amorphous regions of modified starches were preferably to be hydrolyzed during digestion. Compared to modified WCS, the molecular weight of RS was profoundly decreased (6.03×106～1.13×108 g/mol). In addition, the …
