UTILIZATION OF CORN GERM AND SUNFLOWER SEEDS AS A NEW SOURCES OF LECITHINS AND THEIR MODIFIED FORMS IN MANUFACTURE OF CARAMEL

Fractionation and acylation by ethyl alcohol and acetic anhydride were carried out to produce a modified corn germ and sunflower lecithins from their crude leci-thins. Emulsification activity and emulsion stability indices (EAI & ESI) were de-termined at different pH values (2, 4, 6, 8 and 10) for commercial and studied leci-thins. EAI was significantly improved in modified lecithins in comparison to crude lecithins with increasing rate of 52.9 and 58.6 % for corn germ and sunflower etha-nol soluble fraction lecithins and 15.6 and 20.5 % for acylated corn germ and sun-flower lecithins, respectively. The changes in ESI after times of 20, 40 and 60 min. showed a higher stability of emulsions prepared using modified lecithins which were closed to that prepared using commercial soy lecithin. Caramel was prepared using commercial soy, corn germ, sunflower lecithins and their modified forms. Hardness of tested samples was determined in the start of storage time while, acid value, per-oxide value, fatty acid pattern and sensory attributes were determined during storage period at room temperature for six months. Data revealed insignificant difference in caramels hardness. Samples contained crude sunflower; acylated corn germ and sun-flower lecithins were more sensitive to oxidation while, those prepared using com-mercial soy, crude corn germ, ethanol soluble fraction of corn germ and sunflower lecithins showed higher oxidative stability with significant differences (P0.05) to control one that contained commercial soy lecithin. The quality and quantity of lecithin that used in prepared of caramel samples played a major role in their characteristics. The modified corn germ and sunflower lecithin forms were preferred than the raw lecithins owing to their higher emulsifying activity and lesser quantity used. The ethanol soluble lecithins fraction, especially of corn germ can be competitive to the commercial soy lecithin in all emulsified food products

QUALITY EVALUATION OF BEEF STEAKS WITH EDIBLE COATING DURING DEEP - FRYING

Quality of fried beef steaks coated with sodium alginate, carrageenan and car-boxy methyl cellulose (CMC) at concentrations 0.3, 0.6 and 0.9% as well as oils used for frying were evaluated after several frying times (1, 3, 5 and 7 times). Weight loss, shrinkage, moisture loss and final lipid content of control sample were sharply increased after the first time of frying compared to other treatments. The lower reduction in weight loss was achieved in fried beef steaks coated with CMC at concentration of 0.9%. Samples coated with 0.9% carrageenan caused a considerable decrease especially in shrinkage and moisture loss followed by samples coated with CMC and then those coated by sodium alginate at different concentrations. The same treatment (0.9% CMC) showed the lower value of final lipid content. There were significant (p<0.01) decremental patterns in all of sensory attributes (appear-ance, flavor, color, juiciness, mouth feel, texture and overall acceptability) of fried beef steaks during subsequent frying times for all treatments. Less rates of these de-terioration were appeared in CMC samples with different concentrations followed by samples coated with 0.3% and 0.6% of sodium alginate. Progressive rise in acid value of frying oils was especially found in control sample during different frying times, on the other hand the low rate of increase was appeared in sample coated with 0.3% and 0.6% sodium alginate. The higher values of K232 appeared in control sam-ple followed by 0.9% CMC but lower value recorded by oil used for frying beef steaks coated with 0.3% and 0.6% of sodium alginate after 5 times of frying. The same behavior was appeared in K270 determination except there was decrement pat-tern in this criteria by increasing frying times especially from 5 to 7 times of frying in control and coated samples with 0.3% and 0.6% of carrageenan. The highest val-ue of refractive index of fried oil was in control sample followed by coated sample with 0.9% sodium alginate after 7 times of frying. However, the lower value was in coated sample with 0.6% carrageenan under the same conditions. It is cleared to know that, the viscosity of oil which used for frying control sample was lower than that of other treatments during various frying times. Data revealed that the color in-dex (oil deterioration) increase as the concentration of different edible coatings of beef steaks and number of frying increased

BREASTFEEDING PRACTICE AND MOTHERS AWARENESS AND PRACTICE OF ABSOLUTE BREASTFEEDING IN ARAR, SAUDI ARABIA

Background: Human milk meets all the nutritional requirements of infants for the first 6 months of life, and it is associated with a lower incidence of diarrhea than partial or artificial feeding. The infant should be exclusively breastfed for at least 4 months of life and if possible for 6 months, as recommended by WHO and UNICEF. Objectives: The main objective of this study was to determine the breastfeeding status for children under 24 months in Arar city, and to determine breastfeeding practice in relation to some socidemographic and nutrition related variables. Participants and methods: A cross-sectional study was carried out in Arar city, mothers were selected from the attendees of the female side of 6 randomly selected primary health care centers in the city. They interviewed and filled a questionnaire which included the needed questions. Results: Among the 400 studied children,17.2% got breastfeeding, 41.0% had both breast and artificial feeding while 41.8% depended on artificial feeding only. Absolute breastfeeding in the first 6 months of life was found in 34.7% of infants and in the first 4 months of life was found in 13.8%. Sources of health education of the mothers about absolute breastfeeding period were doctors in 12.1%, health education team of the hospitals in 24.1%, relatives and friends in 11.8%, the media in 3.8% while no health education about absolute breastfeeding period was reported by 48.2% of the studied mothers. The reported causes of artificial feeding was difficulty of breastfeeding during working hours in 41.8%, missing of support in 25.7%, preference of formula milk in 11%, thinking that breastfeeding leads to breast enlargement and redundancy in 8.6% and thinking that breastfeeding leads to obesity of the mothers in 4.5%. No significant relationship between type of child feeding and child age, sex, mother education, mother's working status, father's work or mother age group [P >0.05]. Conclusion: 17.2% got breastfeeding, 41.0% had both breast and artificial feeding while 41.8% depended on artificial feeding only. Absolute breastfeeding in the first 6 months of life was found in 34.7% of infants and in the first 4 months of life was found in 13.8%. With deficiency of exclusive breastfeeding among infants of Arar, Saudi Arabia.

PHYSICAL, CHEMICAL AND SENSORY CHARACTERISTICS OF VEGAN CAKE

The objectives of this research were to investigate physical, chemical and sensory quality attributes and their relation of newly formulated vegan cake. Tiger nut milk (TNM) and alginate-lecithin gel (ALG) were used as the replacement of buffalo, s milk and whole egg at the levels of 50 and 100 %, respectively, in addition to, 50 % mixture (50 % TNM and 50 % ALG) and 100 % mixture (100 % TNM and 100 % ALG) . The results revealed that the lactose content of buffalo, s milk was 5.56%, while, TNM was free lactose. TNM is a good source of many elements as buffalo, s milk such as K, P, Ca, Na and Mg. Whole egg had significantly higher foam capacity than the alginate-lecithin gel . In contrast, alginate-lecithin gel exhibited higher foam stability than whole egg. The foam volume of alginate-lecithin gel characterized with stability during 60 min under testing as compared with whole egg that collapsed after 20 min. Concerning emulsifying activity index (EAI), both ALG and whole egg not showed significant difference (p>0.05). Emulsifying stability index (ESI) of alginate-lecithin gel was stable during 60 min under testing as compared with the whole egg that was stable till 40 min. The presence of replacement increased the batter viscosity at ambient temperature over the control value from 19.65 to 21.71-44.54 poise. Among different replacement, 100 % mixtures showed the highest batter viscosity of 44.54 p followed by 100% ALG (38.72 p), 50% ALG (34.29 p) and 50% mixtures (31.03 p). Control batter had a specific gravity of 0.892 g/cc, whereas batter replacing with 50% ALG, 100% ALG, 50% mixtures and 100 % mixtures had a batter specific gravity of 0.992, 1.009, 1.013 and 1.047 g/cc, respectively. The protein and fat contents of control samples were higher (10.42% and 26.63 %, respectively) than vegan cake samples replaced with TNM and ALG. The total carbohydrate content increased with increasing the replacement levels of TNM and ALG in vegan cake. High staling values (high freshness) of vegan cake samples reached 336.59 % and 334.08 % with vegan cake containing 100 % mixtures and 100 % ALG, respectively, in comparison to the staling of control (299.19 %) at zero time. The lower reduction in staling value was achieved in vegan cake prepared 100 % mixtures and 100 % ALG, since the staling value reduced by 10.29 % and 12.41 %, respectively, in comparison to 15.68 % for control sample after 21 days of storage at room temperature. High stability in specific volume during storage was achieved in the presence of 100 % ALG and 100 % mixture since, the specific volume was reduced by only 7.88 % and 8.83 %, respectively, in comparison to 25.99 % for control sample. The presence of ALG and mixtures decreased the hardness value from 79.46 to 36.28 and 66.11 Newton, indicating improvement in the texture of cake. Cakes containing ALG and mixtures showed lower decrement in moisture content and lower increment in hardness during storage at room temperature. Cake samples prepared with different levels of ALG and mixtures were better quality and showed significantly superior sensory properties scores than cake samples prepared with different levels of TNM which coincided with control sample at zero time. Vegan cake samples stored gave higher values and were be desirable till the end of storage period. Therefore, vegan cake could be successfully made from tiger nut milk and alginate-lecithin gel as the fully replacement of buffalos, milk and whole egg, respectively. In addition to, increase freshness, specific volume and storage at room temperature for 21 days

Pattern of chronic urticaria and value of autologous serum skin test in Sohag Province, Upper Egypt

Background: Chronic urticaria (CU) is a debilitating disorder with variable clinical course. It is characterized by hives occurring for at least 6 weeks, and is classified as spontaneous or inducible. Objective: The aim of this study was to detect the pattern of CU, to study association between results of autologous serum skin test (ASST) and urticaria severity score (USS), and to detect serum levels of anti IgE receptors antibodies. Methods: This study included all patients attending the Dermatology Outpatient Clinic, Sohag University Hospital, who were diagnosed as CU from April 2015 to March 2016. ASST and serum level of anti IgE receptor antibodies was assessed using ELISA. Data were analyzed by SPSS version 16, using descriptive statistics, Kruskal-Wallis and Mann-Whitney U test. Results: A total of 108 patients with CU were included in the study. Females with mean age 33±12.4 years were more affected. A total of 58.3% complained of CSU, 6.5% physical urticaria and 35.2% mixed type of CU. According to USS, mild score represented 20.4%, moderate 46.3% and severe in 33.3%. ASST showed positive in 38% of patients. There was a statistically significant relation between ASST and USS and duration of CU. This indicates that more severe symptoms and prolonged duration of CU are observed in positive ASST (autoreactive type). In all, 91% of the anti IgE receptor antibodies positive patients had positive ASST. Conclusion: In conclusion, chronic urticaria is not an uncommon disease in our locality which represented 1.13% of our patients. Urticaria severity score and duration of urticaria was higher in positive ASST patients and hence the autoreactive type

Clinical and subclinical neuropsychiatric abnormalities in rheumatoid arthritis patients

Background Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory disease with probable autoimmune aetiology. RA has many secondary complications and a variety of neuropsychological consequences. Aim The aim of this study was to estimate the frequencies of neuropsychiatric disorders in RA patients and their relationship with the duration and activity of disease. Patients and methods Seventy-four consecutive female RA patients were recruited and compared with 25 age-matched and education status-matched female healthy volunteers. All eligible participants underwent clinical, laboratory and electrophysiological examinations (motor and sensory nerve conduction study, F-wave of four limbs, P300 event-related potential and electroencephalography). The Structured Clinical Interview for Diagnostic and statistical manual of mental disorders, 3rd ed., Revised (DSM-III-R) Axis I Disorders (SCID-I) for diagnosis of psychiatric illness and the Wechsler Adult Intelligence Scale, 3rd ed. (WAIS-III) with assessment of total scale, verbal and performance intelligence quotients (IQ) were administered to all participants. Results Fourteen (18.9%) patients had evidence of symptomatic peripheral neuropathy and radiculopathy, whereas 60.8% had psychiatric disorders. Depression was the most prevalent psychiatric disorder (45%), followed by anxiety (27%) and comorbid anxiety with depression (21.6%). Low IQ scores were recorded in 54% of patients. P300 latency was significantly prolonged (P = 0.0001), and seven (9.5%) RA patients recorded abnormal P300 latency (>mean ± 2 SD) compared with control values. Abnormal electroencephalography findings were observed in 48.6%. Visual analogue scale pain score was significantly higher among patients with psychiatric disorders versus patients without psychiatric disorders (P = 0.0001). Significant negative correlation was recorded between Disease Activity Score and total IQ score (P = 0.01), whereas no significant association was seen between Disease Activity Score and the presence of neuropathy or psychiatric disorders. Conclusion Cognitive impairment, depression, anxiety and peripheral neuropathy are common in RA patients. Early diagnosis and management of neuropsychiatric disorders in RA patients may greatly improve the patients′ health-related quality of life

Factors influencing childhood anaemia in Bangladesh: a two level logistic regression analysis

Background: Anemia is not only a major public health problem among children in developing countries, it is also an important predictor for their future growth and development. The objective of this study was to identify possible factors associated with anemia among pre-school children in Bangladesh after removing a cluster effect of the population, and to determine the prevalence of this condition. Methods: Data for this study was extracted from the 2011 Bangladesh Demographic and Health Survey (BDHS-2011). In this survey, data was collected using a two-stage stratified cluster sampling approach. The chi-square test and a two-level logistic regression model were used for further analysis. Results: Data from 2231 children aged 6-59 months were included for analysis. The prevalence of child anemia was noted to be 52.10%. Among these anemic children, 48.40% where from urban environment and 53.90% were from rural areas. The prevalence of mild, moderate and severe anemia among children was 57.10, 41.40 and 1.50% respectively. The two-level logistic regression model revealed that the following factors were associated with childhood anemia: children of anemic mothers (p < 0.01), undernourished children (p < 0.05), younger children (age < 2 years) (p < 0.01) and children from poor family (p < 0.05). Lastly, anemia was more common among children living in Barisal and Rangpur divisions compared to those from Dhaka division (p < 0.01), and among non-Muslims than Muslim (p < 0.05). Conclusions: Our study showed that prevalence of anemia among pre-school children in Bangladesh was very high (52.10%). We noted that young children of anemic mothers, from poor families, and being undernourished were at higher risk of developing anemia. Since most of these risk factors were related to socioeconomic conditions, they were potentially modifiable. Therefore, our findings may be useful for the health authorities to identify children at risk for remedial action and to plan for preventive measures
