Rice Milling

Rice bran is a component of raw rice that is obtained when it is removed from the starchy endosperm in the rice milling process. Processing was carried out by using microwave and probiotic treatment. The study revealed that rice bran was stabilized by microwave heating (2450MHz for 3min). Stabilized rice bran was inoculated with Lactic Acid Bacillus culture and used as probiotic treated rice bran. Free fatty acid percentage of stabilized rice bran ranged from 4.10 to 7.50 from initial to 4th week and in probiotic treated rice bran it was 4.35 to 7.95 up to 4 weeks of storage period. Functional properties of rice bran were analyzed for stabilized and probiotic treated rice bran i.e. bulk density (0.22-0.38g/ml), water absorption (2-3ml/g), oil absorption (1.5-2.5ml/g), water solubility (7.3-8.0%) and swelling power (6.7-7.2%) respectively. Macronutrient composition of stabilized and probiotic treated rice bran for moisture, protein, fat, ash and carbohydrate were 4.30 and 5.40, 17.50 and 19.25, 13.10 and 17.20, 4.92 and 4.64, 52.33 and 48.55 g/100g respectively and it contained 7.85 and 4.96 g crude fibre, 21.17 and 13.10 g insoluble dietary fibre, 2.17 and 1.80g soluble dietary fibre and 23.34 and 14.90g total dietary fibre. Mineral content of stabilized and probiotic treated rice bran for calcium, phosphorous, iron and zinc were 52.10 and 49.90, 1185.20 and 1186.50, 28.10 and 30.05, 6.02 and 5.89 mg/100g respectively. Processing helps in destroying the lipolytic activity using microwave stabilizing technology, which increases the shelf life of rice bran and improves the nutrient content.

Kenaf Seed

Kenaf seeds are underutilized source of food with good source of dietary fiber, protein, essential oil, and phytocompounds. The objectives of this study were to determine the nutritional composition of kenaf seeds, the techno-functional properties of kenaf seeds dietary fibre (KSDF), and sensory analysis of pan bread fortified with dietary fibre that was extracted from kenaf seeds. Analyses showed that kenaf seeds are rich in dietary fibre (28.87 g/ 100 g), protein (27.07 g/ 100 g), oil (23.78 g/100 g) and mineral (5.55 g/100 g). The dietary fibre that was extracted through enzymatic hydrolysis (KSDF (EH)) exhibited significantly (p < 0.05) greater water-binding capacity (WBC), oil-binding capacity (OBC) and viscosity than non-enzymatic hydrolyzed kenaf seeds dietary fibre (KSDF (NEH)) and defatted kenaf seed meal (DKSM). Different formulations of bread were prepared by replacing 10% of wheat flour with wheat bran fibre (positive control), rice bran fibre and KSDF, with white bread unfortified with fibre as negative control. Addition of 10% KSDF to bread formulation significantly (p < 0.05) reduced bread height, volume, specific volume, water activity and firmness, and increased proofing time and bread surface colour. Results from the sensory evaluation of the bread samples also showed that KSDF bread was the most acceptable in comparison to rice bran and wheat bran fortified breads. This study shows that kenaf seed has valuable source of dietary fibre with the potential to be used as a functional ingredient in the development of functional breads.

Abstract The objective of this study was to evaluate minerals and nutrient composition of young coconut husk silage fermented with rice bran at different concentrations. The study was conducted for seven months in the Laboratory of Feed Technology of State Agricultural Polytechnic of Kupang. A completely randomised design was employed with four treatments and five replicates. The treatments were young coconut husk without rice bran (P0) or the husk plus 4% (P1), 8% (P2) or 12% (P3) of rice bran out of the silage total weight. Variables measured were dry matter, ash, crude protein, crude lipid, crude fibre, Calcium, Potassium and Phosphorus. Analysis of variance showed that rice bran significantly (P<0.01) affects all variables measured. The Duncan’s range multiple test showed that 12% and 4% were the best rice bran concentrations to increase nutrient content and minerals of the silage, respectively. It can be concluded that adding 12% of rice bran to young coconut husk silage increased dry matter, ash, crude protein and crude lipid but reduced Calcium and Potassium. Crude fibre and Phosphorus increased at the inclusion of 8% rice bran.  Key words: Nutrient; Minerals; Rice bran; Silage; Young coconut husk.   Abstrak Penelitian yang bertujuan untuk mengevaluasi komposisi nutrien dan mineral silase sabut kelapa muda pada berbagai level penambahan dedak padi, telah dilaksanakan selama 7 bulan di Laboratorium Teknologi Pakan Politeknik Pertanian Negeri Kupang, dengan menggunakan rancangan acak lengkap dengan 4 perlakuan yang terdiri dari P0 : sabut kelapa muda tanpa dedak padi, P1 : sabut kelapa muda + 4% dedak padi, P2 : sabut kelapa muda + 8% dedak padi, P3 : sabut kelapa muda + 12% dedak padi dengan 5 kali ulangan.

Sphenostylis Stenocarpa

The nutritional and mycoflora changes in dried African yam beans (Sphenostylis stenocarpa) were investigated during a storage period of twenty weeks. The result of the proximate analysis (g/100 g) showed that the following moisture content decreased from 11.15-9.80, fat 1.25-0.49, crude fibre 6.18-2.64, crude protein 77.92-62.14 while the ash content increased from 3.20-3.78, carbohydrate content 0.36-18.32. The mineral analysis (mg/100 g) showed a decrease in all parameters investigated, sodium (Na) 2.57-1.35, potassium (K) 42.26-31.75, calcium (Ca) 21.45-12.56, magnesium (Mg) 27.75-20.72, iron (Fe) 0.25-0.12, zinc (Zn) 0.06-0.05, copper (Cu) 0.03-0.03, phosphorus (P) 32.08-22.03, manganese (Mn) 0.11-0.06, chromium (Cr) 0.002-0.001. Lead (Pb), cadmium (Cd) and nickel (Ni) were not detected. Five fungi comprising four genera were isolated using direct plating, washing and dilution methods on Potato Dextrose Agar (PDA), and identified using their cultural and morphological features with reference to standard procedures. The fungi isolated were Aspergillus niger, Aspergillus flavus, Penicillium sp., Mucor sp. and Phytophthora palmivora. It can be concluded that storage encourages proliferation of mycoflora thereby leading to reduction in the nutritional and mineral composition of the stored sample.

Edible insects, regarded as a potential contributor to food security are currently given wide consideration due to their rich protein and other micronutrients contents. In this study, protease-assisted hydrolysis proposes an economically effective approach to hydrolyse proteins from silkworm (Bombyx mori) pupae to improve its functional properties. The proteolytic activity of a novel neutral protease (265.14 U/ml) with appreciable thermal activities, was identified using 16S rDNA as Stenotrophomonas maltophilia JW20 (SmNP20). The neutral protease with an apparent molecular weight of 28 kDa emerged active at pH 7 and maintained stability in pH range 6.0-8.0. The optimum temperature was 60 °C and stable at 55-60 °C, maintaining over 80% of its initial activity, with a half-life of 78.75, 89, 66.8 and 44 min at 50, 60, 70 and 80 °C. It was purified to 9.98-fold with a specific activity of 455.06 U/mg and 63.73% yield. The Km and Vmax values were 0.70 mg/ml and 9.48 μmol/min/mg, respectively. Enzymolysis with neutral protease enhanced the degree of hydrolysis (97.46±4.87%), increased water solubility over 50%, and a significant protein solubility of 63.44±0.65%. The Km and Vmax of the protein yield were 0.24 mg/ml and 165.63 μmol/min/mg respectively. A total of 17 amino acids have been detected in the hydrolysates obtained from the silkworm pupae protein. In comparison with neutrase and flavorzyme®, the enzyme possesses an elevated hydrolytic and catalytic efficiency. Emulsion activity and foam capacity ranged from 8-48 m2/g and 6-25% respectively. Hence, this study confirms the unique and efficient characteristics of an insect-enzyme correlation that is practically significant with potential improvement in nutritional composition and functional quality of insect proteins.

Cape Gooseberry

Cape gooseberry (Physalis peruviana L.) is a South American fruit with high nutrient content, pleasant taste and antioxidant properties. However, its consumption in some countries is underеvalued. The aim of this study was to determine the nutritional composition of two genotypes of Cape gooseberry fruit produced in Bulgaria (CG-F and CG-P) and to compare it with imported Colombian fruits (CG-C). The samples were assayed for size, diameter, moisture, ash, titratable acidity, pH, protein, lipid, carbohydrate, natural pigments, and mineral content. Bulgarian genotypes were smaller in size than the imported Colombian fruits. The protein content (2.54-1.88 g/100 g) was relatively higher in the imported variety, compared with the locally produced fruit. Carbohydrate content (10.23-14.13 g/100 g) slightly varied between the genotypes. The sweetness of the fruit was due to the main detected sugars – sucrose, glucose and fructose. CG-F and GC-C genotypes had similar sweetness indices, and fruit taste was evaluated as sweet-sour. Pectin content did not exceed 1.85%; the cellulose content varied between 4.29% and 6.64%. Moreover, all investigated fruit had a low lipid content (below 1.00%). The total chlorophyll and carotenoids levels were the highest in the local genotype CG-P (3.62 and 22.36 µg/g). Potassium was the predominant macro-element in all genotypes; there were numerical differences in the rest of the minerals (Ca, Mg, Fe, Cu, Zn, Mn), while the heavy metals, Pb, Cd and Cr, were generally absent. Cape gooseberry fruit of Bulgarian origin was evaluated as a low-calorie nutrient, compatible with the imported Colombian fruit.

Nutrition Policies

The remarkable increase over the past 40 years in some chronic diseases, including the metabolic syndrome, has increased the demand for government and international policies to encourage various approaches to decrease the risk of these diseases. There are some prerequisites for working out successful national food and nutrition policies. Firstly, it is necessary to have a clear picture of the dietary pattern in a country and its associated public health problems. Based on these data, nutrient recommendations and goals are formulated by international or national scientific committees. Governments should translate these nutrient goals into food goals and eventually into national dietary guidelines. The means by which the national authorities can implement a nutrition policy include fortification and supplementation. Equally important are educational and informative tools, such as labelling on the packed food products including information about ingredients and nutrient content. With respect to the metabolic syndrome, this implies nutrient recommendations regarding the intake of fat and carbohydrates (energy per cent) and dietary fibre; dietary guidelines regarding balance between energy intake and expenditure; decreased consumption of products rich in fat and increased consumption of cereals and other products rich in dietary fibre, etc.; recommendations from the authorities regarding nutrient labelling (content of fat and dietary fibre) on relevant products; and nutrient and health claims and other aids (symbols) as tools to make it easier for consumers to select the appropriate food products.
