Understanding The Effect Of Single- And Twin-Screw Extrusion Processing Parameters On Physical And Physico-Chemical Properties Of Sprouted Quinoa And Sprouted Proso Millets, Gabriela John Swamy

Electronic Theses and Dissertations

According to Mordor Intelligence Research, the new compositional research and moisture content extrusion process are helping the growth of the plant protein market. The demand for plant proteins is growing at a fast rate, owing to change in lifestyle, lack of balanced dietary intake, and improved research and development in order to develop new kinds of plant-protein enriched products. It is necessary to identify the right plant protein sources and choose the right processing methodology to create highly digestible foods which can be consumed by infants and elderly as well. In addition, it is important to support local farmers and …

Understanding The Effect Of Extrusion Processing Parameters On Physical, Nutritional And Rheological Properties Of Soy White Flakes Based Aquafeed In A Single Screw Extruder, Sushil Kumar Singh

Sushil Singh

The rapid expansion of aquaculture has increased the demand for aquafeed. As fishmeal is expensive, alternative plant based protein sources such as soybean has shown to be a good alternative for aquafeed production. The present study was done to investigate the effect of soy white flakes (SWF) as an alternative source of protein in the production of aquaculture feed through extrusion processing. Ingredient blends containing different levels of SWF along with distiller dried grains, corn flour, corn gluten meal, fish meal, vitamin and mineral mix with net protein adjusted to 32% protein were formulated. The ingredient blends were extruded in …

Valorization Of Proso Millet And Spent Grain For Extruded Snack Development, Joseph Woomer

Theses and Dissertations--Biosystems and Agricultural Engineering

Fast-paced lifestyles result in consumers replacing traditional meals with on-the-go snack foods. In general, snacks are higher in saturated fats and simple sugars, and pose health concerns for consumers, which prompts the need for healthy nutritious alternatives to common snacks. Proso millet is a nutritious, and fast growing gluten free cereal. Spent grain (SG), the main by-product of brewing and distilling, contains high amount of protein and insoluble fibers. This study utilized proso millet and spent grain in the production of an extruded expanded snack, demonstrating their appropriateness as an ingredient in food production.

The first objective of this study …

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 …

Understanding The Impact Of Extrusion Processing On Rheological, Textural And Functional Properties Of High-Protein, High-Fiber Extrudates, Poonam Singha

Electronic Theses and Dissertations

Extrusion processing is a technology widely used to make ready-to-eat snack and breakfast cereal products. Expanded products mainly consists of high levels of starch resulting in optimal texture and consumer acceptance. However, these products are usually low in nutritional value. One of the many alternatives are to combine legumes and cereals to improve the protein quality of the product. Another possibility is to enhance the nutritional value by incorporating fruits and vegetables. Fruits and vegetables are consistently under-consumed by the American population and incorporation into extruded products may help increase the intake of important nutrients, such as dietary fiber. The …

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 …

Extrusion And Alkali Extrusion Of Corn Stover To Improve Enzyme Saccharification, Shujing Zhang

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Biomass pretreatment constitutes an important part in the whole process of bioethanol production. The main goals of pretreatment include improving cellulose accessibility to enzyme, enhancing sugar yields from hemicellulose, achieving low capital and energy costs, as well as low sugar degradation and low chemical requirements. Extrusion, as a continuous and high throughput pretreatment method, requires much less chemical compared to traditional alkali pretreatment. In this research, twin-screw extrusion was evaluated for its effect with regard to promoting sugar yields from corn stover. Also, the underlying factors contributing to this improvement were examined. It was found that extrusion with no chemicals …

Utilization Of Distillers Dried Grains For Fish Feed By Extrusion Technology—A Review, Nehru Chevanan, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Kurt A. Rosentrater

Protein-rich distillers dried grains (DDG) from ethanol plants has been used as livestock feed for many years. Feed conversion efficiency in fish, however, is typically much higher compared to traditional livestock. But, the cost of fish feed is one of the challenges for profitable fish cultivation. Due to the exponential growth of ethanol plants in recent years, DDG is becoming readily available as a reasonably-priced base material for animal feeds, and because it has a relatively high protein content, it also has much potential for use as a fish feed ingredient. Even though much literature is available on conversion of …
