  • Underweight patients were studied with respect to changes in their nutritional status before and after administration of nutritional beverage. Patients with renal hepatic or endocrine disease gastrectomy malabsorption and weight gain over past 6 months were excluded. Ten patients were participated as controls and were allowed to eat ad libitu, Twenty patients were served as case and were administered in addition to their usual diet 400ml of nutritio-nal beverage(Greenbia) high in calorie and protein for 8 weeks. In the beginning of the study most underweight patients showed depressed nutritional status in terms of calorie intake quality of protein intake and the levels of visceral protein status and serum micronut-rients. The controls consumed less amounts of calories proteins vitamins and minerals while those given the nutritional beverage exceeded their estimated energy requirement(105%) and consumed a mean of 96g protein per day. Those given nutritional beverage for 8 weeks showed significant increase in body weight(3%) hemoglobin(3.2%) hematocrit(5.4%) serum transferrin(19.4%) iron(30.1%) and zinc(20.9%) In the controls however significant improvement was not observed in any parameters compared with initial values. significant improvement was not observed in any parameters compared with initial values. This study suggests that patients with underweight can show mild nutritional deprivation nutritional support can improve their unbalanced status and prevent severe malnutrition.

  • To investigate the nutritional quality of packaged meals produced by packaged meal manufactures, a nutritional evaluation was conduced. Samples examined in this study were 95 Products which composed of 86 Doraks, 7 Kimplabs and 2 Yubuchopabs Produced in packaged meal manufactures in Seoul City and Kungki-do province The distribution of food groups showed that amounts of animal foods were abound, but amounts of green vegetables, limited in Dosirak comparing to one meal RDA levels. Amounts of meats, fishes and shells are increased more than amounts of egged and legumina with increase of price of Dosirak. The total kinds of food and the amounts of certain food in Kimpab and Yubuchopab were lower than Dosirak. The energy and protein contents of Dosirak were found to be higher than one meal RDA levels, with exception of protein content in Dosirak of the price 1000 won. The contents of energy and protein in Kimpab and Yubuchopab are less than one meal RDA levels. Calcium and iron contents in Dosirak, and calcium content in Yubuchopab were present in excess compared to the one meal RDA. However, In Kimpab, calcium and iron contents were lower than the one meal RDA. On the whole, vitamin contents of Dosirak were sufficient whereas vitamin contents of Kimpab and Yubuchopab were lower than the one meal RDA. Number of side dishes used in Dosirak were 6-23 items depending on prices. Guidelines were suggested for effective nutritional quality control of packaged meals.

  • Muscle fillets of flounder, Limanda herzensteini, were sliced into small pieces and dehydrated by the methods of sun drying, hot air drying and vacuum freeze drying, and evaluated for the protein quality by the method of shortened pepsin pancreatin digest residue (SPPDR) index which is the modified method of shortened pepsin digest residue index. In the analysis of the muscle protein hydrolysates, glutamic acid, aspartic acid and lysine comprised about 39% of the total amino acids of the protein. The content of pure protein in flounder muscle was 18.8%. The result of nutritional evaluation of the dried muscle protein by the computation of the SPPDR index showed that the freeze dried flounder muscle protein was superior in the nutritional efficiency to the others, sun dried. The freeze dried flounder muscle protein marked 89 of the SPPDR index number which is quite similar to the muscle protein of terrestrial animal in nutritional quality.

  • Various processing methods have a great impact on the physiochemical and nutritional properties of meat that are of health concern. Hence, the postmortem processing of meat by different methods is likely to intensify the potential effects on protein oxidation. The influence of meat protein oxidation on the modulation of the systemic redox status and underlying mechanism is well known. However, the effects of processed meat proteins isolated from different sources on gut microbiota, oxidative stress biomarkers, and metabolomic markers associated with metabolic syndromes are of growing interest. The application of advanced methodological approaches based on OMICS, and mass spectrometric technologies has enabled to better understand the molecular basis of the effect of processed meat oxidation on human health and the aging process. Animal studies indicate the involvement of dietary proteins isolated from different sources on health disorders, which emphasizes the impact of processed meat protein on the richness of bacterial taxa such as (Mucispirillum, Oscillibacter), accompanied by increased expression of lipogenic genes. This review explores the most recent evidences on meat processing techniques, meat protein oxidation, underlying mechanisms, and their potential effects on nutritional value, gut microbiota composition and possible implications on human health.

  • The purpose of this study is to evaluate the nutritional status of protein and lipids in the patients with alcoholic liver disease, to find an effective way of dietary management for patients with alcoholic liver disease and to obtain the materials for nutritional education for alcoholics. The subjects consist of 80 patients with alcoholic liver cirrhosis(ALC) and 12 patients with alcoholic fatty liver(AFL). The control group included 57 alcoholics without liver disease(A), 32 patients with viral liver cir rhosis(VLC) and 194 normal(NL). Biochemical evaluation of nutritional status was performed by ana lyzing the profiles of protein and lipids in blood samples. The results are summarized as follows: 1) The frequency of subjects below the normal range of serum total protein was 26.3% in ALC, 16.7% in AFL and 3.5% in A. Serum albumin was lower in 41.3% of ALC. 2) The alcoholics without liver disease showed significantly higher level of serum triglycerides, total cholesterol and LDL cholesterol than the other groups. The alcoholic subjects had lower HDL cholesterol than normal subjects. Overall, the protein and lipids status of the alcoholic subjects in this study was evaluated to be very poor on the basis of biochemical assessments. The results suggest that alcohol abuse and poor dietary intake could cause malnutrition. An extensive nutritional education should be emphasized for the alcohol consuming population. High quality of protein and other dietary intakes from early stage of the disease may be effective in nutritional therapy for the patient with alcoholic liver disease.

  • Soybean meal (SBM), a commonly used protein source for animal feed, contains anti-nutritional factors such as trypsin inhibitor, phytate, oligosaccharides among others, which limit its utilization. Microbial fermentation using bacteria or fungi has the capability to improve nutritional value of SBM by altering the native composition. Both submerged and solid state fermentation processes can be used for this purpose. Bacterial and fungal fermentations result in degradation of various anti-nutritional factors, an increase in amount of small-sized peptides and improved content of both essential and non-essential amino acids. However, the resulting fermented products vary in levels of nutritional components as the two species used for fermentation differ in their metabolic activities. Compared to SBM, feeding non-ruminants with fermented SBM has several beneficial effects including increased average daily gain, improved growth performance, better protein digestibility, decreased immunological reactivity and undesirable morphological changes like absence of granulated pinocytotic vacuoles.

  • The objective of this study was to evaluate the nutritional content of bullfrog meat from different parts of the animal, including fore-chest, thigh and calf. Bullfrog meat was found to be a rich source of proteins, essential amino acids and minerals, but with a low fat content, compared with other aquatic meat products. There was no significant difference (p>0.05) between thigh and calf in mineral content (K, P, Na, Mg, Ca, Zn, Fe, Cu, and Mn), but the contents of K, P, and Mg were higher in thigh and calf than in the fore-chest (p<0.05). The salt-soluble, water-soluble and insoluble protein bands in sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) electrophoresis, from fore-chest, thigh and calf were similar, with the most abundant bands being 35 kDa (salt-soluble protein), 35-48 kDa (water-soluble protein) and 48 kDa (insoluble protein). The results showed that the insoluble protein content in the fore-chest meat was higher than that in the thigh meat and calf meat, but the salt-soluble protein fraction was the most abundant in thigh meat. These results showed that the nutrients in different parts of bullfrog meat were different.

  • Peanut seeds are characterized by high oils and proteins with good quality, and are utilized as an edible oil source and a protein-rich food products. The end products, being peanut butter, salted seed, confections, roasting stock and other by-products are favored in world-wide because of their unique roasted peanut flavor. As with many other foods, interest in the composition and chemistry of peanut is largely a result of thier use as human food. Thus, a more complete knowledge of thier chemical and food quality and flavor properties is desired. Literatures are reviewed mainly focucing on the physicochemical properties and nutritional quality of oil, protein and flavor in peanuts. Chemical properties of protein and oil, and volatile flavor component in peanut seeds are studied extensively in view point of chemical and food nutritional value. But in crop base, the synthesis and genetic studies of the chemicals could not provide valuable informations on the breeding for quality improvement. Some essential amino acids are limiting in peanut seeds and the tocopherols are very important in oil stability and for dietary adequacy ratio in high linoleic acid peanut oil, but it is thought to be quite difficult to improve by breeding technique as their lack information of gene actions. However, the selections of high protein and oil, and some essential amino acids and linoleic acid rich genotypes could be helpful for the quality improving. Research studies are also needed to elucidate the relationships between flavor components and consumer perception of peanut flavor.

  • Protein-energy malnutrition is regarded as one of the public health problems in developing countries as a result of poor feeding practices due to poverty. This study, therefore, aimed at evaluating nutritional quality of a potential weaning food formulated from locally available food materials. The cooking banana fruit(CB) and bambara groundnut seeds(BG) were purchased from local market in Akure, Ondo State, Nigeria. The CB and BG were processed into flours, mixed in ratios of 90:10, 80:20, 70:30 and 60:40 and subjected into proximate, sensory and biochemical analyses using standard procedures. Nutrend(a commercial formula) and ogi(corn gruel, a traditional weaning food) were used as control. The nutritient composition(g/100 g) of the food samples were ranged as follows: moisture 2.94-6.94, protein 7.02-16.0, ash 1.76-2.99, fat 0.76-8.45, fibre 1.52-3.75, carbohydrate 63.84-88.43 and energy 1569.8-1665.7 kcal. The biological value(BV), net protein retention(NPR), protein efficiency ratio(PER) and feed efficiency ratio(FER) of the experimental food samples were significantly(p<0.05) lower than nutrend, but higher than ogi. The haematological variables of rats fed with formulated food samples, commercial formula(nutrend) and traditional weaning food(ogi) were not significantly(p>0.05) influenced by the dietary treatment. However, the values obtained for red blood cell(RBC), white blood cell(WBC), pack cell volume(PCV) and erythrocyte sedimentation rate(ESR) were higher in the experimental food samples than the commercial food. The growth rate of animals fed with experimental food samples were lower than those fed with the nutrend, but higher than those fed with ogi. In conclusion, the nutritional quality of CB and fermented BG mix of 60:40 ratio was better than ogi; and comparable to the nutrend. This implies that it can be used to replace low quality traditional weaning food and the expensive commercial weaning formula.

  • Two completely randomized block design experiments were conducted to evaluate the effect of gamma irradiation processing of canola meal on performance parameters of broiler chicks (Ross 308) and protein quality of canola meal. Protein efficiency ratio (PER) and net protein ratio (NPR) were measured as indices of canola meal protein quality. Samples of canola meal were tested for nutritional value after being irradiated at dose levels 10, 20 and 30 kGy. Glucosinolate content was reduced 40, 70 and 89 percent at irradiation dose levels of 10, 20 and 30 kGy respectively (p<0.01). Percent of erucic acid in total fatty acid content increased 44, 58 and 48% as a function of radiation dose (p<0.01). Dose levels did not affect feed conversion ratio (FCR) and body weight gain of chicks (p>0.05). Liver weight was decreased by irradiation dose (p<0.05). The same trend was observed for kidney weights, but this trend was not significant (p>0.05). Gamma irradiation processing of canola meal had no significant effect on $T_3$ level in blood of chickens that consumed canola meal, but $T_4$ level of chicken blood at the 30 kGy dose decreased significantly (p<0.05). PER and NPR were not affected by radiation dose level (p>0.05). Gamma irradiation seems to be a good procedure to improve the nutritional quality of canola meal.
