Only bioaccessible nutrients can be absorbed and used by the body to contribute to health. The study aimed to investigate the effect of extrusion on the in vitro bioaccessibility of β-cryptoxanthin and zeaxanthin in extrudates supplemented with red pepper pulp. Corn grits mixed with red pepper pulp were extruded. β-cryptoxanthin, zeaxanthin, and total phenolic content with antioxidant activity analysis were conducted on the feed and extruded samples. Quality parameters of the corn grit extrudates, prepared with and without red pepper pulp, were also investigated. The extrusion process significantly increased the in vitro bioaccesibiliy of zeaxanthin, but no statistically significant difference was observed for β-cryptoxanthin. After the extrusion process, total phenolic, β-cryptoxanthin, and zeaxanthin contents with antioxidant activity were lower. Physical quality parameters such as hardness, expansion, and water absorption with water solubility index values were not affected by the addition of red pepper meal. The porosity decreased, and hence the bulk density increased. Sensory analysis showed that the preference scores of the panelists for the samples with the addition of red pepper meal were not different from the control. This study showed that the extrusion process could improve the in vitro bioaccessibility of functional components. Additionally, red pepper pulp can be added as a functional ingredient to extrudates to develop new products without changing consumer preferences.

Investigation of in-vitro digestive behavior of beef and poultry which are tenderized by enzymatic and acidic marination Baştürk, Bilge; Öztop, Halil Mecit; Özvural, Emin Burçin; Department of Food Engineering (2021-9-09) Meat contains valuable nutrients, exceptionally high-quality proteins that include all essential amino acids and vitamins and minerals for the human diet. Meat is mostly tenderized to make it more tasteful and palatable. The effects of tenderization on the physical, chemical, and microbiological changes in meat have been investigated in many studies. In this study, acetic acid, citric acid, lactic acid solutions, and a commercial meat tenderization solution were used to tenderize the red and white meat (bee...
A biomechanical and spectroscopic study of bone from rats with selenium deficiency and toxicity Turan, B; Bayari, S; Balcik, C; Severcan, Feride; Akkas, N (2000-06-01) Selenium, being an essential mineral in the mammalian diet, is important in providing protection against oxidative damage. Numerous in vitro studies of selenium compounds reveal a very high correlation between catalytic activity of selenium compounds and toxicity. The present study was designed to investigate the effects of dietary selenium on the biomechanical properties of bone. New born rats of both sexes were fed with either a control, or a selenium- and vitamin E-deficient, or a selenium-excess and vit...
Physical Changes in White and Brown Rice during Simulated Gastric Digestion KONG, Fanbin; Öztop, Halil Mecit; SINGH, R. Paul; MCCARTHY, Michael J. (2011-08-01) Previous studies have shown that brown rice generates lower glycemic responses than white rice, a trait that may be beneficial in the dietary management of chronic diseases such as diabetes and hyperlipidemia. The objective of this study was to investigate influence of rice digestion on the physical properties of the gastric digesta that may further impact intestinal absorption. A dynamic stomach model, human gastric simulator, was used to simulate the gastric digestion of white and brown rice. The pH, soli...
Developmental selenium exposure and health risk in daily foodstuffs: A systematic review and meta-analysis Ullah, Habib; Liu, Guijian; Yousaf, Balal; Ali, Muhammad Ubaid; Abbas, Qumber; Munir, Mehr Ahmed Mujtaba; Mian, Md Manik (2018-03-01) Selenium (Se) is a trace mineral and an essential nutrient of vital importance to human health in trace amounts. It acts as an antioxidant in both humans and animals, immunomodulator and also involved in the control of specific endocrine pathways. The aim of this work is to provide a brief knowledge on selenium content in daily used various foodstuffs, nutritional requirement and its various health consequences. In general, fruits and vegetables contain low content of selenium, with some exceptions. Seleniu...
Determination of optimum cropping pattern of irrigation fields Özcan, Cem; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2017) Water and nutrients are the main physiological requirements of human beings and therefore vegetal nutrients are of great importance to humans. In order to obtain the required plant diversity under the conditions of variable climate, soil and topography, it is necessary to ensure that the amount of water required by the plant during the growing season is stored in the root zone of the plant, which is called "irrigation". Global warming and population growth factors increase the need for water, which necessit...
