  • The Impact of Food Viscosity on Eating Rate, Subjective Appetite, Glycemic Response and Gastric Emptying Rate
    The Impact of Food Viscosity on Eating Rate, Subjective Appetite, Glycemic Response and Gastric Emptying Rate Yong Zhu1, Walter H. Hsu2, James H. Hollis1* 1 Department of Food Science and Human Nutrition, Iowa State University, Ames, Iowa, United States of America, 2 Department of Biomedical Sciences, Iowa State University, Ames, Iowa, United States of America Abstract Understanding the impact of rheological properties of food on postprandial appetite and glycemic response helps to design novel functional products. It has been shown that solid foods have a stronger satiating effect than their liquid equivalent. However, whether a subtle change in viscosity of a semi-solid food would have a similar effect on appetite is unknown. Fifteen healthy males participated in the randomized cross-over study. Each participant consumed a 1690 kJ portion of a standard viscosity (SV) and a high viscosity (HV) semi-solid meal with 1000 mg acetaminophen in two separate sessions. At regular intervals during the three hours following the meal, subjective appetite ratings were measured and blood samples collected. The plasma samples were assayed for insulin, glucose-dependent insulinotropic peptide (GIP), glucose and acetaminophen. After three hours, the participants were provided with an ad libitum pasta meal. Compared with the SV meal, HV was consumed at a slower eating rate (P = 0.020), with postprandial hunger and desire to eat being lower (P = 0.019 and P,0.001 respectively) while fullness was higher (P,0.001). In addition, consuming the HV resulted in lower plasma concentration of GIP (P,0.001), higher plasma concentration of glucose (P,0.001) and delayed gastric emptying as revealed by the acetaminophen absorption test (P,0.001).

Berichterstatter: Prof. Dr. Thomas A. Vilgis 2. Berichterstatter: PD Dr. Wolfgang Schärtl Tag der mündlichen Prüfung: 17. Mai 2016 Prüfungskommission: Prof. Dr. Thomas A. Vilgis PD Dr. Wolfgang Schärtl Prof. Dr. Angelika Kühnle Prof. Dr. Heiner Detert “A Thing is a Thing, not what is said of that Thing.” II Abstract Abstract The present work presents two different ways to achieve physically modified tapioca starch and the influence on mechanical properties of an aqueous starch paste is investigated. A completely cold soluble tapioca starch powder is produced by spray drying a previously gelatinized starch paste. Rehydrating the received white powder forms a viscous paste with significant loss in elasticity. Heating of a native tapioca starch suspension in contrast yields highly viscous paste with dominating elastic behavior. The combination of the spray dried tapioca starch with nongelling food hydrocolloids, such as xanthan gum, ι-carrageenan, and guar gum restores the mechanical properties and creates new starch-based thickening agents with stable structure. Rheological measurements of a gelatinized native tapioca starch paste compared to a rehydrated paste made from the spray dried starch show significant differences in viscosity and viscoelastic properties, which depend on temperature, amplitude, frequency, or shear rate. Further rheological, optical, and scattering investigations indicate weakening of the amylose network structure generated by the harsh shear and heat conditions during the spray drying process.

The food components are in the form of solids, in solutions or in the form of colloids - sols or emulsions. The properties of these components determine the quality of food. The quality of a food product, you would realize, is also usually assessed by means of human sensory organs, the evaluation being called ‘sensory’ or ‘subjective’ or ‘organoleptic’. Here, in this unit, we shall study about various sensory attributes of food. What characteristics make a food attractive and appealing? How does appearance and colour of a food affect our choice? Does smell has a role to play in making a food choice? Do mouth-feel and finger-feel contribute to food acceptance? All these attributes of a food product come under what we refer to as quality of foods. In this unit, we will learn about these quality attributes of food.

  • Food Rheology (Fst 310)
    FOOD RHEOLOGY (FST 310) DR. A. A. ADEBOWALE 1 INTRODUCTION Rheology is the science of flow and deformation of matter and describes the interrelation between force, deformation and time. The term comes from Greek rheos meaning to flow. Rheology is applicable to all materials, from gases to solids. The science of rheology is only about 70 years of age. It was founded by two scientists meeting in the late 1920s and finding out they have the same need for describing fluid flow properties. The scientists were Professor Marcus Reiner and Professor Eugene Bingham. The Greek philosopher Heraclitus described rheology as panta rei - everything flows. Translated into rheological terms by Marcus Reiner; this means everything will flow if you just wait long enough. Fluid rheology is used to describe the consistency of different products, normally by the two components: viscosity and elasticity. By viscosity is usually meant resistance to flow or thickness and by elasticity usually stickiness or structure. Rheological relationships help us to understand the fluids we are working with so that we can either know how they are behaving or force them to behave according to our needs. Once a correlation has been developed between rheological data and product behaviour, the procedure can then be reversed and rheological data may be used to predict performance and behaviour. Food rheology Described as the study of the deformation and flow of the raw materials, the intermediate products and the final products of the food industry. The rheological property of a food system is dependent on the composition or the ingredients of the system.

  • The North African Journal of Food and Nutrition Research, 5(11): 1-9
    https://doi.org/10.51745/najfnr.5.11.1-9 Abstract Background: Overconsumption of added sugars, particularly refined sugars, has been shown to be associated with adverse health concerns. Aim: The present study aimed to elaborate calorie-reduced marmalades with nutritional benefits as well as satisfactory sensory properties, in order to reduce sugar intake without compromising consumers' acceptance. Materials and methods : Two formulas of sugar-reduced marmalades were elaborated by substituting 30% of sucrose with different commercial non-nutritive sweeteners: a blend of aspartame-acesulfame-K and sucralose. Physico-chemical, sensory, and microbiological analyses were carried out, in comparison with control sample marmalade. Blood glucose concentrations were determined in 12 healthy volunteers, at 30-min intervals until 120 min after consumption of marmalades. Results: Marmalade quality characterization revealed a significant effect of sucrose substitution on dry extract, Brix, reducing sugars, aw, and CIE Lab color parameters, but not on pH and acidity. The microbiological analysis highlighted that marmalades’ sanitary quality was in accordance with safety standards. Interestingly, sensory analysis by trained panelists showed that the substitution of sucrose by an intense sweetening substance did not impair the sensory properties. Our data also indicate that consumption of calorie-reduced marmalades significantly reduced acute postprandial glycemic responses in healthy volunteers; this effect was more pronounced with sucralose. Conclusions: Taken together, our results showed that the use of sucralose can constitute a relatively healthy choice for food basket of families, in particular for those with high risk of lifestyle-related diseases. Keywords: Citrus marmalade, Aspartame-acesulfame-K, Sucralose, Calories reduction, Quality, Glycemic response.

Smith Received: 17 December 2015; Accepted: 8 March 2016; Published: 14 March 2016 Abstract: There is increasing emphasis on reformulating processed foods to make them healthier. This study for the first time comprehensively investigated the effects of fortifying bread (containing oil as an ingredient) with freeze-dried vegetables on its nutritional and physico-chemical attributes. Breads fortified with carrot, tomato, beetroot or broccoli were assessed for nutrition, antioxidant potential, storage life, shelf stability, textural changes and macronutrient oxidation. Furthermore, using an in vitro model the study for the first time examined the impact of vegetable addition on the oxidative stability of macronutrients during human gastro-intestinal digestion. As expected, adding vegetables improved the nutritional and antioxidant properties of bread. Beetroot and broccoli significantly improved bread storage life. None of the vegetables significantly affected bread textural changes during storage compared to the control. Lipid oxidation in fresh bread was significantly reduced by all four types of vegetables whilst protein oxidation was lowered by beetroot, carrot and broccoli.
