Research ArticleOpen accessEvery word in the titleIdentification and Quantification of Major Carotenoids in Some VegetablesJafar Muhammad EL-QudahAn HPLC study of 6 raw vegetables (Okra, green beans, eggplant zucchini, carrot and tomato) most frequently consumed worldwide was carried out to determine their carotenoid composition. The samples were purchased from supermarket in the city of Boston, USA. Neoxanthin, violaxanthin and lutein were contained in all samples except tomato for neoxanthin, carrot and tomato for violaxanthin and carrot for … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 11,131 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDietary Intake of Selected Common Vegetable Foods and their Total Carotenoids DeterminationJafar Muhammad EL-QudahProblem Statement: Vitamin A Deficiency (VAD) remains widespread in many countries including Jordan, mainly due to inadequate dietary intake of vitamin A and carotenoids. Approach: Few researches on carotenoid content in vegetables and fruits are carried out. Thus, the aim of this study was to evaluate the dietary intake of selected common foods among a sample of adult Jordanians, by … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,115 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePresent a Mechatronic System Having Able to Determine the Concentration of CarotenoidsRaffaella Aversa, Eleni Buzea, Relly Victoria V. Petrescu et al.Civilization besides its major advantages (undisputed) brought us some unhealthy habits which unfortunately have managed to penetrate deeply within several generations on the current planetary populations producing great damages to its health. Perhaps it would be the right time to and more people learning to live healthy, to feed ourselves healthy, let's try to break the chain of evil which … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 7 Dec 2016 · 8,567 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBioconversion of Carotenoids in Five Fruits and Vegetables to Vitamin A Measured by Retinol Accumulation in Rat LiversArmando Carrillo-Lopez, Elhadi M. Yahia, Gabriela K. Ramirez-PadillaProblem statement: Vitamin A deficiency is one of the most prevalent and major nutritional problems in developing countries, especially in young children. In many countries, a substantial proportion of dietary vitamin A is commonly derived from pro-vitamin A carotenoids obtained from colored fruits and orange or green vegetables. However, the bioavailability of retinol derived from carotenoids from these plant sources … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,926 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSupercritical Fluid Extraction of Palm CarotenoidsPuah C. Wei, Choo Y. May, Ma A. Ngan, Chuah C. HockThe extraction of carotenoids from crude palm oil was carried out in a dynamic (flow- through) supercritical fluid extraction system. The carotenoids obtained were quantified using off-line UV-visible spectrophotometry. The effects of operating pressure and temperature, flow rate of the supercritical carbon dioxide (SC-CO2), sample size of feed used on the solubility of palm carotenoids were investigated. The results showed … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,762 accessesView PDFCite

Kradetskaya et al.The paper presents information about the cultivation of spring durum wheat in the conditions of Northern Kazakhstan. Methods for assessing the quality of grain and semolina in the breeding process are shown: SDS sedimentation, protein content according to Kjeldahl, content, and index of gluten using the Glutomatic 2200 system, vitreousness, hardness SKCS 4100, content of carotenoid pigments, measurements of the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 2 Sep 2022 · 6,087 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Induction of Lycopene in Germinating Cottonseed with 2-(4-Methylphenoxy) Triethylamine (MPTA)Lorraine S. Puckhaber, Jinggao LiuAbstract: Problem Statement: Increasing carotenoids content in foods was currently of great interest. The present paper reports strong stimulatory effect of MPTA on the carotenogenesis in cotton, which was used as a model. Approach: Cotton seedlings were treated with MPTA vs. water and germinated in the dark. The levels of carotenoids were determined by HPLC and the expression levels of … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 26 Jul 2011 · 7,950 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBioconversion Efficiency of β-Carotene from Mango Fruit and Carrots in Vitamin AJose de Jesus Ornelas-Paz, Elhadi M. Yahia, Alfonso A. Gardea-BejarProblem statement: Bioconversion efficiency of β-Carotene (BC) in vitamin A is strongly influenced by food matrix. This efficiency has been determined mainly in typical BC sources like carrots. BC content in mango fruit is considerably high however; the bioconversion efficiency of BC from fresh mango in vitamin A has not been determined nor compared with those of typical BC sources. … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,428 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Temperature and Time to the Antioxidant Activity in Plecranthus amboinicus Lour.Mohd S. Azman Abdul Rahim, Jailani Salihon, Mashitah Mohd Yusoff et al.Problem statement: Processing of food involving heat will contribute to loss of nutritional content, thus it is important to measure and control temperature and time to reduce the loss. Approach: Examine the effects of variations in boiling temperature and boiling time on the antioxidant activity of the boiling extract of Plecranthus amboinicus Lour. Fresh plants were boiled at 45, 60, … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 9,249 accessesView PDFCite
Review ArticleOpen accessIn the abstractStrigolactones in Plant Stress Adaptation: Mechanisms and Agricultural PotentialHumayra Ferdus, Mahabuba Mostafa, Md. Motaher HossainAbiotic stresses have significant negative effects on the growth, development, and productivity of crop plants, which are critical to global agricultural production and ecosystem stability. Strigolactones (SLs), a family of carotenoid-derived plant phytohormones, have been identified as playing key roles in plant development and adaptive responses to environmental stimuli. Initially recognized as signaling molecules in host-parasite interactions and as symbiotic … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 3 Oct 2026 · 559 accessesView PDFCite
