Purple rice has become an interesting source of nutritional value among healthy cereal grains. The appropriate cultivation together with post-harvest management would directly benefit farmers and consumers. This study aimed (i) to determine the yield, grain nutritional quality, and antioxidant capacity of purple rice varieties grown at lowland and highland elevations, and (ii) to evaluate the effects of storage conditions on the stability of the rice nutritional value during six months of storage. The high anthocyanin PES variety grown in the lowlands had a higher grain yield than the plants grown in the highlands, but grain anthocyanin concentration had the opposite pattern. In the high antioxidant capacity KAK variety, grain yield and DPPH activity were not significantly different between plants grown at the two elevations. The storage of brown rice and vacuum-sealed packages were both found to preserve greater anthocyanin concentrations in PES, but there was no effect on the DPPH activity of KAK. The grain properties were not significantly different between storage at 4 °C and room temperature. This study suggests that the optimal cultivation practices and storage conditions would result in the higher yield and grain quality of purple rice varieties.

<p>Different processing conditions, packaging and storage can affect the natural antioxidant protection of the egg. Thus, the objectives were: (a) To standardize a methodology able to evaluate in vitro antioxidant capacity of fresh and processed egg, (b) investigate the effect of pasteurization and spray on the oxidative stability of the lipid fraction of egg and (c) evaluate the antioxidant capacity and oxidative stability of fatty acids from whole egg pasteurized atomized, bottle of high density polyethylene, opaque, under nitrogen, at 5&plusmn;2&ordm;C for up to 90 days. The phosphomolybdenum method to measure the total antioxidant capacity of lipid fraction (CATL) Egg presented analytical adequacy, with a limit of quantification of 0.017 mg &alpha;-tocoferol/mL. The CATL decreased with the progress of processing and the reverse was observed for the lipids, 7-CETO (7-ketocholesterol) and TBARS (thiobarbituric acid reactive substances). The pasteurized egg atomized (OIPA) kept under ideal storage conditions considered stable in relation to hydration, CATL and TBARS. It is concluded that the method of phosphomolybdenum suitability presented analytical sufficient. Pasteurization did not affect any of the parameters evaluated, but the atomization caused significant decrease CATL, and elevated lipids, TBARS and 7-CETO. Was maintained hydration and stability of the lipid OIPA stored for 90 days at 5&deg;C, indicating that the conditions for packaging and storage were effective.&nbsp;</p><p>&nbsp;</p><p>DOI:&nbsp;<a href="http://dx.doi.org/10.14685/rebrapa.v4i1.102">http://dx.doi.org/<span>10.14685/rebrapa.v4i1.</span><span>102</span></a></p><p><span><br /></span></p>

Mineral elements are essential micronutrients necessary to constitute human tissue and maintain normal physiological functions. Micronutrient deficiencies are an important issue currently faced in the world. The best strategy to solve this problem is to breed special functional types of rice varieties rich in trace elements (special rice for short). A special type of rice that can produce rich nutrients. In order to explore the nutritional value of giant embryo rice, the contents of 17 mineral elements ((K, Ca, Fe, Se, Zn, Cu, Na, Mn, Mg, Ni, Cr, Co, Pb, As, Cd, Ag, Al)) in 5 kinds of giant embryo rice (white giant embryo, giant japonica-GB-12, giant japonica-GB-11 and giant japonica-GB-5, giant japonica-GB-1) were detected by inductively coupled plasma mass spectrometry. After comparison with ordinary rice, it was found that the content of the same mineral element in different samples has a large variation, suggesting that different rice varieties have different absorption, transformation and storage efficiency of the same element; different giant embryo brown rice in some mineral elements (such as Cr, Ni, Cu and Zn) are extremely low in content and almost undetectable. Meanwhile, the brown rice of giant embryo rice has a more powerful enrichment effect on some mineral elements, which means that embryo rice has a unique advantage in cultivating new rice varieties with special functions rich in minerals.

Background: Public interest and awareness of the use of functional food as an obesity nutrition therapy are increasing. Objective: This study aims to analyze the content of energy, macronutrients, minerals (magnesium, manganese, and potassium), and bioactive components (fiber, β-glucan) in Indonesian varieties of brown rice compared to white rice, to provide precise information on the nutritional content of brown rice as a functional food in obesity nutrition therapy. Methods: This research took the form of a laboratory analysis to identify the content of energy, macronutrients, fiber, β-glucan, magnesium, manganese, and potassium in brown rice varieties Sinta Nur. The energy content of rice was analyzed using bomb calorimetry; macronutrients were analyzed by spectrophotometry, gravimetric extraction, and acid-base titration; dietary fiber, and β-glucan were analyzed by enzymatic methods; and mineral contents were analyzed by spectrophotometry and atomic absorption spectrophotometry. Results: The results demonstrated that the energy and macronutrient content of brown rice are higher than white rice. However, brown rice also has dietary fiber and β-glucan contents that are 5 times higher than white rice. For the macronutrient, in brief, magnesium content was 7.7 times higher, potassium was 5.7 times higher, and manganese was 1.59 times higher within the brown rice. Cooked rice is known for lower nutritional value, but the nutritional value of Indonesian brown rice is still higher than white rice. Conclusion: The results of this study indicate that brown rice has nutrient content and bioactive components that allegedly contribute to higher obesity intervention than white rice.

Rice is now the main food for about 35 million people in Nigeria, and consumption is increasing faster than that of any other food crop in many countries in Africa. This study provided essential engineering data on the physical properties of selected varieties of local rice in Nigeria. Some selected physical properties of Igbemo, Ofa- da and Abakaliki rice varieties at harvest, market, and storage conditions were evaluated as a function of moisture content. The latter ranged from 12.38 to 25.69% (dry base). We also determined the physical properties of the rice samples, such as moisture content, linear dimensions, geometric mean diameter, arithmetic mean diameter, surface area, aspect ratio, sphericity, bulk density, and hundred kernel weights. A result of the linear dimensions for the major diameter was 8.4–10.3 mm, 6.4–6.55 mm, and 5.9–7.4 mm for harvested, marketed, and stored rice, respec- tively. The minor diameter ranged from 2.70 to 3.29 mm, 2.49 to 2.63 mm, and 2.56 to 2.74 mm, and the intermedi- ate diameter of the rice varieties at harvest, market, and storage conditions was 1.92–2.29 mm, 1.90–2.02 mm, and 1.87–1.99 mm, respectively. Depending on the conditions and varieties, the bulk density, true density, and porosity, was observed to be between 0.59 to 0.90 g/cm3, 2.28 to 5.57 g/cm3 and 70.38 to 85.35% respectively.

Agronomic Biofortification

A field experiment on agronomic biofortification in rice varieties through zinc fertilization under aerobic condition was carried out at Assam Agricultural University, Jorhat during autumn season of 2014. Among the Varities, Inglongkiri recorded significantly higher grain yield (21.09 q/ha) followed by Banglami (19.88 q/ha) under aerobic condition. Application of ZnSO4 @ 25 kg/ha + foliar spray @ 0.5% at 3 stages recorded the highest grain yield (21.46 q/ha) followed by application of ZnSO4 @ 25 kg/ha + seed priming with ZnSO4 (2%) (20.72 q/ha). The lowest grain yield was recorded in control treatment (16.47 q/ha). Highest grain Zn content (32.03 mg/kg) and Zn content of brown rice(without polish) (26.81 mg/kg) was noticed in Inglongkiri. Application of ZnSO4 @ 25 kg/ha as basal + foliar spray @ 0.5 % at three stages reveals significantly highest Zn content in grain (35.09 mg/kg) and brown rice (28.31mg/kg).
