Development Of Barnyard Millet Puffed Product Using Hot Air Puffing And Optimization Of Process Parameters, Raghunath Vyankatrao Jaybhaye, Dinesh Nandkumar Kshirsagar, Premprakash Srivastav Sep 2011

Development Of Barnyard Millet Puffed Product Using Hot Air Puffing And Optimization Of Process Parameters, Raghunath Vyankatrao Jaybhaye, Dinesh Nandkumar Kshirsagar, Premprakash Srivastav

Raghunath Vyankatrao Jaybhaye

Abstract A ready-to-eat (RTE) puffed product was developed from barnyard millet using high temperature short time (HTST) puffing process. Cold extruded dough sheet pieces prepared from barnyard millet flour, potato mash and tapioca powder in the proportion 60:37:3 were steam cooked and then puffed in hot air puffing setup. The effect of process parameters viz. steaming pressure (SP), steaming time (St), hot air temperature (AT) and puffing time (Pt) on the product quality was investigated by conducting experiments using the central composite rotatable design (CCRD). Linear and quadratic models were developed using response surface methodology (RSM) to study the synergy …


Development Of Carrot Pomace And Wheat Flour Based Cookies, Navneet Kumar Dr. Jul 2011

Development Of Carrot Pomace And Wheat Flour Based Cookies, Navneet Kumar Dr.

Navneet Kumar

Carrot is the excellent source of beta carotene and other vitamins. The carrot is utilized as raw, cooked vegetable, sweet meats or as juice and beverages. Carrot pomace is the by-product of carrot juice extraction process. The carrot pomace was dried in hot air oven at 65°C and then grinded to pass through 2 mm sieve. Dried carrot pomace was added in different proportions (0 –9%) to fine wheat flour, shortening, sugar and water. The formulation was baked at 175 °C for 12 min. in the gas oven with air circulation. The moisture content of cookies was measured using hot …


Electromagnetic And Heat Transfer Modeling Of Microwave Heating In Domestic Ovens, Krishnamoorthy Pitchai Apr 2011

Electromagnetic And Heat Transfer Modeling Of Microwave Heating In Domestic Ovens, Krishnamoorthy Pitchai

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Microwave (MW) ovens are used extensively for heating a variety of not-ready-to-eat food products. It is vital to achieve target temperature uniformly throughout the food to inactivate foodborne pathogens to assure safety. Non-uniform heating of foods in microwave ovens is the major concern in assuring microbiological safety of such products. The non-uniform heating of foods in domestic microwave ovens is due to complex interactions of microwaves with foods. A comprehensive coupled electromagnetic and heat transfer model was developed using finite-difference time-domain based numerical method to understand the complex interaction of microwaves with foods. Simulation parameters such as cell size, heating …
