The Effects Of Compaction On Reconstitution Characteristics Of Dairy Powder, Michelle P. Dixon, Rose Prabin Kingsly Ambrose, Dhananjay Ashok Pai
The Summer Undergraduate Research Fellowship (SURF) Symposium
Milk powders are becoming more ubiquitous within the food industry, and they offer consumers a convenient form for direct intake of dairy. The costs associated with dairy are reduced when products are converted to powder, which markedly increases shelf life at ambient temperatures. Creating compacts from powders further improves cost efficiency by reducing volume. However, milk powders typically possess poor rehydration properties, such as a slow dispersion rate and low solubility, and powder compaction additionally prolongs rehydration time, reducing consumer acceptability. Previous studies have shown that modifying dairy products before or during the drying process can improve rehydration properties, but …
Analysis Of The Flow Behaviors Of Corn Meal During Extrusion, Daniel N. Hauersperger, Martin R. Okos, Troy Tonner
Analysis Of The Flow Behaviors Of Corn Meal During Extrusion, Daniel N. Hauersperger, Martin R. Okos, Troy Tonner
The Summer Undergraduate Research Fellowship (SURF) Symposium
Food extrusion can be used to make many products we consume today, including pasta, cereals and more. The ability to predict the characteristics of the final product from an extruder using raw material characteristics and operating conditions is vital to the extrusion process. In order to answer this need, the flow behavior of corn meal was measured in a lab viscometer (off-line) and compared to the flow behaviors from an extruder (in-line) at three different moisture contents (32.5%, 35%, 37.5% wet basis). The extruder and product are heated through the friction of the corn meal passing through the barrel not …
Processing Methods And Storage Conditions On Chocolate And Coffee Powder Flow Properties, Sunland L. Gong, Andrea Della Bella, Teresa M. Carvajal
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 …
Determination Of Master Compliance Curve For Extruded Semolina Pasta, Laura E. Emery, Martin Okos
Determination Of Master Compliance Curve For Extruded Semolina Pasta, Laura E. Emery, Martin Okos
The Summer Undergraduate Research Fellowship (SURF) Symposium
The dependence of the rate of relaxation of semolina pasta on moisture content and temperature and how it affects shrinkage during drying has not yet been determined. The purpose of this research was to develop an equation that relates moisture content and temperature in order to obtain a master curve for creep of the product. When found, this equation could help to optimize the drying process and increase the quality of the final pasta product. Semolina flour mixed with water and propionic acid to create a 35% wet basis product was extruded on a C.W. Brabender 2523 to obtain a …
Optimization Of Oil Extraction Of Soy Flour Using Mini Extrusion Technology, Alisha Chess, Martin Okos
Optimization Of Oil Extraction Of Soy Flour Using Mini Extrusion Technology, Alisha Chess, Martin Okos
The Summer Undergraduate Research Fellowship (SURF) Symposium
Mini extrusion technology is a relatively new technology that offers fast timing and processing of food products. This technology paired with the advantageous properties and growing demand for soybeans can lead to a larger span of uses for the extruder that have not yet been explored, including NASA space missions and incorporation of soybeans into developing countries. During past research on parameters of operation, it was discovered that a significant amount of oil was being separated from the soy meal at the die of the mini extruder. Maximum removal of this oil allows use of the soy meal and soy …
