  • G6PD Deficiency Food to Avoid Some of the Foods Commonly Eaten Around the World Can Cause People with G6PD Deficiency to Hemolyze
    G6PD Deficiency Food To Avoid Some of the foods commonly eaten around the world can cause people with G6PD Deficiency to hemolyze. Some of these foods can be deadly (like fava beans). Some others can cause low level hemolysis, which means that red blood cells die, but not enough to cause the person to go to the hospital. Low level hemolysis over time can cause other problems, such as memory dysfunction, over worked spleen, liver and heart, and iron overload. Even though a G6PD Deficient person may not have a crises when consuming these foods, they should be avoided. • Fava beans and other legumes This list contains every legumes we could find, but there may be other names for them that we do not know about. Low level hemolysis is very hard to detect and can cause other problems, so we recommend the avoidance of all legumes. • Sulfites And foods containing them. Sulfites are used in a wide variety of foods, so be sure to check labels carefully. • Menthol And foods containing it. This can be difficult to avoid as toothpaste, candy, breath mints, mouth wash and many other products have menthol added to them. Mint from natural mint oils is alright to consume. • Artificial blue food coloring Other artificial food color can also cause hemolysis. Natural food color such as found in foods like turmeric or grapes is okay. • Ascorbic acid Artificial ascorbic acid commonly put in food and vitamins can cause hemolysis in large doses and should be avoided. It is put into so many foods that you can be getting a lot of Ascorbic Acid without realizing it.

(FABACEAE) *Sarita A. Kukade and Jaikiran A. Tidke Laboratory of Reproductive Biology of Angiosperms, Department of Botany, Sant Gadge Baba Amravati University, Amravati 444602 (M.S.) India *Author for Correspondence ABSTRACT Dolichos lablab is an ancient legume crop widely grown throughout the world for its vegetable or pulse for human consumption or as animal forage or feed. It is a semi-erect, bushy, perennial herb, cultivated as an annual. It flowers during the months of September to February. Large numbers of small flowers are arranged in long recemes. Flowers open between 11.00am to 04.00pm. Anther dehiscence occurs before flower opening. The stigma becames receptive during 08.00am to 07.00pm on the day of flower opening. The stigma is wet, papillate and the style is solid. Pollen viability percentage in TTC was found to be 94.89%. The percentage of in vivo pollen germination was recorded as 38.80% which was found to be increased to 40.48 and 54.25% on the second and third day respectively. Flowers are visited by several insects. However, Xylocopa, ants, thrips, butterflies are the main visitors. Keywords: Dolichos Lablab, Pollen Viability, Pollen Germination INTRODUCTION Many flower visiting insects and other animals are engaged in a remarkable mutualism with the plants. As bees, butterflies and other pollinators forage for resources found within flowers, such as pollen, nectar or more rarely other substances such as scents or resins, their bodies contact sexual organs of plants (Waser, 2001).

  • Nutrient Composition of Cooked Lablab Bean Varieties
    i NUTRIENT COMPOSITION OF COOKED LABLAB BEAN VARIETIES FOR IMPROVING NUTRITION AND FOOD SECURITY IN TANZANIA MONICA MICHAEL MORRISON A DISSERTATION SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE IN HUMAN NUTRITION OF SOKOINE UNIVERSITY OF AGRICULTURE. MOROGORO, TANZANIA 2019 ii ABSTRACT Legumes are important crops for improving food and nutrition security in Africa. However, there are few nutrition researches on lablab beans in Africa, except for programs focusing on improving soil properties. This study was conducted to evaluate the nutritional composition of seven varieties of cooked lablab beans grown in Tanzania. The lablab bean varieties both green and dried were cooked then analyzed for chemical composition, cooker-ability and sensory qualities. The parameters studied in chemical composition were proximate composition (protein, carbohydrates, fat, fiber, ash, moisture and carbohydrate) and mineral content (Calcium, Copper, Iron, Manganese and Zinc). Anti-nutritional factors investigated were phytic acid and tannin. Sensory quality parameters assessed were appearance, colour, mouth feel, taste and overall acceptability. Results showed that, both green and dried beans had chemical composition that could meet the recommended amounts of nutrients. Based on proximate composition ILRI6536 had highest content of protein (29.75 g/100 g) and Eldoret Black had highest fibre content (12.5 g/100 g). Based on mineral composition, DL 1002 had the highest Iron (3.35 g/100 g) and Calcium contents (3.93 g/100 g) while ILRI 6536 had the highest Zinc content (8.7 g/100 g). Lower levels of anti-nutrients were observed in ILRI 6536 (2.88 g/100 g) for tannin and Echo Cream (1.10 mg/100 g) for phytic acid and higher content of both phytic and tannin were in Echo Cream.

  • Studies on the Proximate and Mineral Composition of Three Varieties of Lablab Beans (Lablab Purpureus)
    International Journal of Applied Agricultural Research ISSN 0973-2683 Volume 5 Number 3 (2010) pp. 291–300 © Research India Publications http://www.ripublication.com/ijaar.htm Studies on the Proximate and Mineral Composition of Three Varieties of Lablab Beans (Lablab Purpureus) *K.O. Soetan1 and M.A. Fafunso2 1Department of Veterinary Physiology, Biochemistry and Pharmacology,University of Ibadan, Nigeria 2Department of Biochemistry, University of Ibadan, Nigeria *Corresponding Author’s E-mail: [email protected] Abstract The proximate and mineral composition of three varieties of lablab beans (Lablab purpureus) were studied. The three varieties used for this study were Rongai brown (PI509 114), Rongai White (NAPRI 4) and Highworth black (Grif 12293). Rongai brown variety had the highest concentration of crude protein, crude fat, ash and of gross energy. There were significant differences (P< 0.05) in the crude protein, crude fibre and the nitrogen free extracts in all the three varieties of the lablab beans. Potassium, phosphorus, magnesium and iron were appreciably high in all the three varieties while calcium and sodium concentrations were low. It is concluded that the lablab beans can be used as a source of dietary proteins especially in developing and under developed countries where consumption of animal protein may be limited as a result of economic, social, cultural or religious factors. Keywords: Proximate, mineral composition, Lablab purpureus. Introduction The high cost of animal protein has directed interest towards several leguminous seed proteins as potential sources of vegetable protein for human food and livestock feed (Esenwah and Ikenebomeh, 2008). Legumes are generally well adapted to a wide range of climates and environmental conditions.

Naeem* • M. Masroor A. Khan • Moinuddin • Manzer H. Siddiqui • M. Nasir Khan Plant Physiology Section, Department of Botany, Aligarh Muslim University, Aligarh 202 002, India Corresponding author : * [email protected] ABSTRACT Plant biological yield appears to be comparatively low in calcium (Ca)-deficient soils of Aligarh, Western Uttar Pradesh, India. Here, Ca deficiency poses a serious yield and quality limitation for several crops, including various legumes. Hyacinth bean (Lablab purpureus L.) is a good source of vegetable protein in the human diet. Its seeds and pods contain as much as 20-28% protein. It contains tyrosinase enzyme, which has potential use in the treatment of hypertension. Because of the importance for hyacinth bean as a bio-functional medicinal legume, an experiment was designed to determine whether Ca application through soil could enhance hyacinth bean production, nitrogen fixation, photosynthesis, enzymatic activities, nutraceuticals and quality attributes for this legume. The plants were grown in pots -1 containing soil and supplied with five levels of calcium, viz. 0, 40, 80, 120 and 160 mg Ca kg soil applied as calcium chloride (CaCl2). The performance of the crop was assessed in terms of various growth, physiological, biochemical, yield and quality attributes at 60, 90, 120 and 150 days after sowing (DAS). Ca application proved to be significantly effective on most of the parameters studied. Of the five levels, Ca at 120 mg kg-1 soil showed the best results, significantly stimulating most of the attributes studied at 60, 90, 120 and 150 DAS.
