  • Growth of Raphia Farinifera and Elaeis Guineensis Wine Yeast on Cassava (Manihot Esculenta ) and Poultry Manure Media
    Nyerhovwo J. Tonukari et al. NISEB Journal Vol. 14, No. 3, September, 2014 1595-6938/2014 Printed in Nigeria (2014) Nigerian Society for Experimental Biology http://www.nisebjournal.org Growth of Raphia farinifera and Elaeis guineensis Wine Yeast on Cassava (Manihot esculenta ) and Poultry Manure Media 1,2 1,2 1,2 2 2 Nyerhovwo J.

Anigboro 1 1 Department of Biochemistry, Faculty of Science, Delta State University, Abraka, Nigeria. 2African Research Laboratories, Otorho-Agbon (Isiokolo), Delta State, Nigeria. Abstract The aim of this research was to determine the suitability of cassava (Manihot esculenta) and poultry manure (locally available resources) as substrates for the production of raffia and palm wine yeasts. Yeast growth was estimated as a measure of their medium’s optical density at 600 nm (OD 600 nm ) after 36 h of growth. The various media used were formed from different combinations of cassava flour and poultry manure. The results obtained showed that the growth of the palm wine (Elaeis guineensis Jacq.) yeast in the locally formulated media 3:2, 4:1, 5:0 [poultry manure (PM)(g)/ cassava flour (CS)(g)], and yeast extract-peptone dextrose medium (YPD) was 2.101, 2.830, 3.131 and 2.057 respectively. The OD 600 nm measurement of the growth of the raffia wine (Raphia farinifera) yeast was 2.912, 2.859, 4.000, and 2.110 respectively in the same media above. This shows that formulations 3:2, 4:1, and 5:0 [PM (g)/CS (g)] are highly suitable for the growth of palm wine and raffia wine yeasts when compared with their growth in the standard medium (YPD).

Abstract: Samples of flakes of cassava (Manihot esculenta) popularly known as tapioca from the same source were divided into two and one group was processed by sun-drying along Ezillo Road side while the other by in- door spreading served as control. Atomic Absorption Spectrophotometer model AGP 210 Bulk scientific was used to determine the levels of heavy metals in the tapioca samples. The result (in ppm) revealed the following concentration: Zn (11.13 ± 0.08); Cd (2.50 ± 0.03); As (0.15 ± 0.01); Pb (0.53 ± 0.02) and Cr (3.00 ± 0.04) for sundried tapioca while that of the results (in ppm) of the control (indoor tapioca) were Zn (13.38 ± 0.11); Cd (0.06 ± 0.01); As (0.13 ± 0.01) ; Pb (0.35 ± 0.01) and Cr (1.75 ± 0.03). The levels of heavy metals in samples of sundried tapioca were generally higher than those processed in-doors. Statistical analysis revealed there was no significant difference (p > 0.05) in the mean concentration of Zn, As and Cr in sundried samples when compared with the control, while the levels of Pb and Cd that were significantly (p<0.05).

    May 2015 A cinnamon and benzoate free diet for orofacial granulomatosis: Orofacial granulomatosis (OFG) is a condition which affects mainly the mouth and lips. Swelling and redness are the most common symptoms but other symptoms such as mouth ulcers and cracked lips can occur too. The cause is not known but a cinnamon and benzoate free diet helps 70% of people with OFG. Avoiding foods which contain cinnamon and benzoates may help your oral symptoms. You should try and follow this diet for 12 weeks and monitor any improvements in your symptoms diary. Keep to fresh or home cooked food where possible. If you are unsure whether a food or drink may contain cinnamon or benzoate, it is best to avoid it. It is important that you read the labels of any manufactured or prepared foods you consume. 1 Page 2 of 13 Cinnamon Cinnamon is a natural substance, which because it is used in very small quantities does not always have to be stated on food labels. Look for the word spices, spice extracts, ground cinnamon, mixed spice, cinnamon oil, cinnamal or cinnamic aldehyde on food labels. Benzoates Most benzoates are added to food and drinks as a preservative. They are commonly added to fizzy drinks and processed foods. High levels of benzoates may also occur naturally in certain foods. Benzoates includes any of these preservatives: E210 or Benzoic acid E211 or Sodium benzoate E212 or Potassium benzoate E213 or Calcium benzoate E214 or Ethyl 4-hydroxybenzoate or Ethyl para-hydroxybenzoate E215 or Ethyl 4-hydroxybenzoate, sodium salt or sodium ethyl para-hydroxybenzoate *E216 or Propyl 4-hydroxybenzoate or Propyl para-hydroxybenzoate *E217 or Propyl 4-hydroxybenzoate, sodium salt or sodium para-hydroxybenzoate E218 or Methyl 4-hydroxybenzoate or Methyl para-hydroxybenzoate E219 or Methyl 4-hydroxybenzoate, sodium salt or sodium methyl-hydroxybenzoate *banned in foods produced within the European Union but may be found in imported products.

  • Indonesian Food Culture Mapping: a Starter Contribution to Promote Indonesian Culinary Tourism Serli Wijaya
    Wijaya Journal of Ethnic Foods (2019) 6:9 Journal of Ethnic Foods https://doi.org/10.1186/s42779-019-0009-3 REVIEW ARTICLE Open Access Indonesian food culture mapping: a starter contribution to promote Indonesian culinary tourism Serli Wijaya Abstract The food culture of Indonesia is shaped by several factors such as nature, history, and culture. With its enormous geographic and cultural diversity across the archipelagos, it is evident that Indonesian cuisine is rich in variety and taste. As such, food can be utilised as a strategic means to boost the tourism industry of the country. In the past 5 years, the Indonesian government has given a great support for the development of culinary tourism as one special interest tourism sector that is promoted extensively to the international market. Promoting Indonesian culinary tourism should not be merely exposing the ample varieties of the traditional food that Indonesia has, but more importantly, telling the market about the socio-cultural values behind the food itself. This study aimed to portray how Indonesian food culture has been shaped, developed, and held as the value embedded in the society and has been passed from one generation to the next. For the purpose of the study, a range of literature from journal articles, books, archives, magazines, and articles to Internet sources that are relevant to Indonesian culinary discussions was reviewed. Keywords: Food culture, Indonesian cuisine, Culinary tourism Introduction international visitors [5]. There are thousands of local Food plays a significant part in all aspects of human life, foods which potentially offer a strong focal point to por- including from fulfilling basic physiological needs to tray Indonesia as a tourism destination.

  • The Purpose of a Low Fiber, Low Residue Diet Is to Minimize Stool Output
    Digestive Health Center Nutrition Services Low Fiber Diet Fiber is a component of complex carbohydrates that the body cannot digest, is found in plant based foods such as beans, lentils, fruits, vegetables, whole grains, etc One of the major functions of fiber is to add bulk to stools and promote regular bowel movements Often, a low fiber diet is then used to reduce stool bulk and output. The diet is used for various medical conditions, such as in ulcerative colitis, during the recovery period after intestinal surgery or to reduce risk of an intestinal obstruction if there is a stricture (narrowing) present in the intestinal tract. A low fiber diet is usually about 10-15 grams of fiber per day Although fiber is not found in meats, poultry, fish, eggs and dairy, it may help to promote overall tolerance to foods if you: Avoid tough and fibrous cuts of meats, poultry, etc. Eat cuts that are soft and tender. Avoid large amounts of dairy if dairy is found to be bothersome (examples- cheese sauces, cream sauces etc). Eat dairy then in small amounts and spread out dairy between all the meals. Avoid any meat, poultry, fish, eggs and dairy made with high fiber ingredients (dried fruits, nuts, seeds, etc) 1 Tips for a Low Fiber Diet: There is always more than one way to eat a specific food. It will help to peel, cook and/or blend your foods with fiber to optimize tolerance and enjoy variety in the diet. Eat small frequent meals throughout the day (4-6 meals/day).

    International Journal of Scientific Research in Chemistry (IJSRCH) © 2019 IJSRCH | Volume 4 | Issue 1 | ISSN : 2456-8457 Modelling and Optimization of Ethanol Production from Cassava (Manihot Esculenta) Otaraku I. J.*, Oji A., Obi C. L. Chemical Engineering Department, University of Port Harcourt, Port Harcourt, Nigeria ABSTRACT The need for ethanol optimization from locally sourced material like cassava informed the use of cassava samples to produce ethanol. Two sets of micro-organisms were used for cassava fermentation: Yeast (saccharomyces cerevisiae) obtained from fresh palm wine and zymomonasmobis obtained from decaying oranges. A combination of both the yeast and zymomonasmobis was also prepared as a single solution. The organisms were inoculated into the cassava starch substrate to enhance fermentation for six days. The quantities of starch that were fermented ranged from 5g -25g and the highest volume of ethanol produced was 25cm3 when 10g of starch was inoculated with zymomonasmobis. Distillation was used to determine the volume of ethanol that was produced. The densities obtained were compared to the density of standard ethanol and the results obtained agreed with the specification of standard ethanol. Design and model equations for ethanol production optimization were developed and the results obtained correlated with the experimental results.
