Processing Methods And Storage Conditions On Chocolate And Coffee Powder Flow Properties, Sunland L. Gong, Andrea Della Bella, Teresa M. Carvajal Aug 2015

Processing Methods And Storage Conditions On Chocolate And Coffee Powder Flow Properties, Sunland L. Gong, Andrea Della Bella, Teresa M. Carvajal

The Summer Undergraduate Research Fellowship (SURF) Symposium

Powders are widely used in a countless number of industries, and are crucial to the quality control of products in areas such as pharmaceuticals and food. Particle physicochemical properties (morphology, solid state – crystalline, amorphous or both) are important factors for powder flow, which in turn can have significant impact on the stability, performance, and presentation of powders. Different processing methods as well as storage conditions such as relative humidity (RH) can drastically affect powder flow. Due to the widespread use of chocolate and coffee powder around the world, and their importance to the food industry, this work investigates two …


Impact Of Microwave Processing On Quality Of High Value Shelf Stable Fruit Products, Milena Maria Leon Garcia Jan 2013

Impact Of Microwave Processing On Quality Of High Value Shelf Stable Fruit Products, Milena Maria Leon Garcia

Open Access Theses

Fruits and vegetables are a rich source of health promoting micronutrients and phytochemicals, and their consumption has been associated with reduction of many chronic and degenerative disease. Thermal processing techniques are used to preserve quality and extent of the shelf life of foods, although these traditional processes are associated with specific quality changes in fruits and vegetables. Compared to traditional thermal processing methods, microwave heating provides the potential to improve product quality by virtue of its energy transfer mechanism that provides rapid volumetric heating of food and can potentially enhance overall quality of processed fruit and vegetable products. Though direct …
