The separation efficiency and palm kernel quality of five palm kernel shell separation methods used in selected communities in Rivers State, Nigeria were evaluated. The methods include traditional handpicking, clay-water bath (kaolin), mechanical dry separation, pneumatic and hydrocyclone separations. The weight of recovered palm kernels obtained from each separation method was determined and used in the calculation of separation efficiencies. Free fatty acid (FFA), shell/fibre and moisture content of the palm kernels recovered from each separation method was determined. The results show that the least free fatty acid (FFA) content of (3%) was found in sample separated by the pneumatic method and highest (8%) in the clay-water bath (kaolin) method. High moisture content of 11% was recorded for kernels separated by clay-water bath (kaolin). Pneumatic separation method retained the least percentage of shell/fibre content (2%). Hand picking and clay-water bath (kaolin) methods had shell/fibre retention of 8% and 6%, respectively. However, mechanical, pneumatic and hydrocyclone separation techniques conform to the quality parameters when compared to SON/NIS standard. The mechanical, pneumatic and hydrocyclone separation methods gave higher separation efficiencies of 74, 90 and 96% respectively and palm kernels of superior quality that meets the palm kernel industrial standards. There was no significant difference (P>0.05) in separation efficiencies between the traditional hand picking and the clay water bath methods however there was a significant difference (P<0.05) between the above two methods and mechanical, pneumatic and hydrocyclone separation methods.
This study shows that pneumatic and hydrocyclone separation methods are the most efficient in separating cracked palm kernel mixtures. This study also provide information on the best method of palm kernel recovery that meets quality requirement for Nigerian Industrial standard.

Elrady E. Bukhari. Holli , Abdelazim. A.M. Nour , Adam Ismail Ahmed (2017). Effect of Soaking on the Nutritional Values of Kordala (Maerua Pseudopetalosa) Seeds Grown in Kordofan Region, Sudan. Journal of Food Technology Research, 4(2): 40-45. DOI: 10.18488/journal.58.2017.42.40.45
The aim of this study is to eliminate the alkaloids from Kordala (Maerua pseudopetalosa) by soaking process and examine their effect on nutritional value, protein digestibility and anti- nutritional factors. The seeds were soaked in water for seven days with water changed daily. The proximate composition, protein digestibility, minerals composition, anti-nutritional factors and amino acids profile were examined. The results obtained showed that soaking decreased protein content (from 21.67 to 11.64 %), ash (from 2.9 to 0.3%), fat (from 1.78 to 1.05%), polyphenols (from 170.82 to 160 mg/100g), phytic acid (from 743.5 to 588.9 mg/100g), minerals and amino acids content also decreased. The process increased moisture content (from 8.3 to 9.62%), fiber content (from 1.36 to 4.27%), total carbohydrates (from 63.99 to 73.12%) and protein digestibility (from 58.4 to 68.1%) for raw and soaked seeds, respectively. Comparing these values with recommended dietary allowances, the results indicated that Kordala (Maerua pseudopetalosa) seeds could be a good supplement source for some nutrients.
The present study is one of the first reports concerning investigations on the nutritional values of Kordala (Maerua pseudopetalosa) and studding the role of soaking on the removal of bitter taste in Kordala, which used in Sudan as famine food.

This study assessed government feeding programme on improved nutritional health status of secondary school students in Maiduguri, Borno state, Nigeria. Objectives and corresponding research questions were used in the study. The research design adopted for this study was survey research method. The target population for this study comprised of day public secondary schools in Maiduguri, Borno state, with a total population of nine thousand three hundred and thirty eight (9,338) students. Five public secondary schools were selected using purposive sampling technique. The sample of 934 students was selected using simple and stratified random sampling techniques. A self- developed questionnaire on government feeding programme among students in Maiduguri, Borno State was the instrument of data collection. The response mode for the instrument was a modified four(4) points Likert type scale with a response mode of strongly agree, agree, disagree and strongly disagree. Descriptive statistics of frequency counts, and percentage scores were used to answer the research question, while Chi-square was used to test the hypotheses at 0.05 level of significance. The results showed that the school feeding programme improved the nutritional health status of the students. Based on the findings of the study, it was recommended that Government should employ qualified food scientists, nutritionists, dieticians and caterers to assist in running the programme and to make them responsible for the purchase of needed food items to be cooked in schools. Furthermore, Government should also encourage more international donor agencies like the International Non-governmental organizations to come in with more improved varieties of school meals to increase the nutritional health status of the internally displaced students in the society. School feeding programmes should encompass both public and private primary and secondary educational institutions across the country. Feeding should be well guided by a menu which reflects the nutritional need for energy and micronutrients body requirements of the particular geographical area.
