The aim of this research was to study the changes in soluble protein fractions of six rice varieties cooked by four cooking methods viz. ordinary, pressure, microwave and solar cooking methods. In cooked rice albumin, globulin, prolamin and glutelin fractions ranged from 4.1 to 4.3, 11.6 to 12.2, 3.0 to 3.6 and 80.5 to 81.0 % under various cooking methods against 6.4, 14.6, 4.6 and 74.4 % in the uncooked samples. Results indicated that albumin, globulin and prolamin fractions decreased significantly after cooking. This decrease was accompanied by a significant increase in the glutelin fraction as compared to uncooked rice samples. Among cooking methods, albumin in pressure and solar, globulin in solar and prolamin in ordinary were significantly (P<0.05) higher than other methods. However, in respect of glutelin content microwave and solar cooking methods were superior to ordinary but at par to pressure cooking method.

CHEMICAL COMPOSITION AND ORGANOLEPTIC CHARACTERISTICS OF PROCESSING BAT (Pteropus alecto) FRESH MEAT. Study was done to evaluate chemical composition and preference degree of the consumers on the processing bat meat compared with beef, chicken and cakalang fish using steam cooking method, flavor cooking and spicy cooking method. Chemical composition was analyzed by proximate analysis using procedures of the Association of Official Analytical Chemists. The organoleptic test was done by hedonic test. Data of the hedonic test were analyzed using Kruskal-Wallis method. To evaluate data distribution of the panelist respons on the sample test, the data were using plot graphic box. The hedonic scales were using 1 to 7. The variables used were including color, taste, flavor, tenderness and general acceptance. Results of proximate analyses of bat meat based on fresh meat indicated that water content was 67.21 percents and protein was 20.48 percents. Based on dry matter, the protein contents of bat meat, pork, chicken, and cakalang fish were 48.97 percents, 69.08 percents, 67.14 percents, and 69.41 percents, respectively. The water contents were 5.76 percents, 9.92 percents, 8.27 percents, and 9.90 percents, repsectively; the calcium (Ca) contents were also 10.62 percents, 1.09 percents, 1.36 percents, 1.38 percents, respectively; while Phosphor (P) contents were 1.46 percents, 0.69 percents, 0.66 percents, and 0.72 percents, respectively. Variance analysis for organoleptic test showed that meat type with different processing affected significantly on taste, color, flavor, tenderness and general preference of bat meat, beef meat, chicken meat and cakalang fish by steam cooking, chicken flavor, and spicy cooking methods. Conclusion, bat meat contained protein relatively lower than that in pork meat, chicken meat, and cakalang fish, but mineral contents were relative higher. Results of organoleptic test showed that preference degree of processing meat were higher on using spicy flavor. The specific test on taste, color, flavor, tenderness and general responsed showed relatively the same responses by the panelists.   Key word: Chemical composition, organoleptic test, processing bat meat

Abstract Phosphine residues were determined in 2 types of rice samples, raw polished and parboiled. The yellow chromophore due to phosphine from raw polished rice had 2 absorption maxima, a strong one at 370- 380 nm and a weaker one at 400-410 nm. The chromophore from parboiled rice also had 2, one at 390-400 nm and the other at 410-420 nm. A closed system containing rice and a phosphine tablet or powder yielded 93-99% recovery of fortified phosphine. At any given dose of phosphine, parboiled rice retained a higher amount of residue after aeration than did raw polished rice.

Rice is the staple food of Indonesian which has superior taste which made it rooted in the eating culture in Indonesia. Nowadays, there is still limited research comparing cooking methods in various rice varieties. This study aim to analyze the eff ect of various cooking methods and rice variety on sensory quality. There were two cooking methods tested, traditional method that combines boiling and steaming, and rice cooker steaming method. Sensory test (quality characteristic) and acceptance test were measured using hedonic scale on 30 semi-trained panelist to evaluate the eff ect of cooking method on four rice variety, that are white rice Berlian Sae, white rice Super Slyp, brown rice, and black rice. Statistical test used was ANOVA and continued with Duncan test. Results showed diff erences in ratio of water and cooking time of various types of rice with diff erent methods. White rice (Slyp Super) with conventional cooking methods was more acceptable to panelist with the characteristics of bright colors, smell, neutral taste, and delicate texture. There was a signifi cant diff erence in panelist acceptance based on type of rice (p<0.05) which brown rice and black rice had lower acceptability than white rice. There was no signifi cant diff erence in acceptance by cooking method (p>0.05), but there was a tendency that traditional method has higher acceptability. Color indicator became main indicator for panelist determined overall acceptability, so that it can be considered in the development of rice cooking methods.

Background: Globally, hot cooked refined rice is consumed in large quantities and is a major contributor to dietary glycaemic load. This study aimed to compare the glycaemic potency of hot and cold stored parboiled rice to widely available medium grain white rice. Method: Twenty-eight healthy volunteers participated in a three treatment experiment where postprandial blood glucose was measured over 120 minutes after consumption of 140g of rice. Three rice samples were freshly cooked medium-grain white rice, freshly cooked parboiled rice, and parboiled rice stored overnight at 4 &ordm;C. All rice was served warm at 65 &ordm;C. Chewing time was recorded. Results: The 24-hours cold-stored and reheated parboiled rice resulted in a 42% and 12% lower blood glucose concentration trajectory than freshly cooked medium-grain white rice and freshly cooked parboiled rice. Chewing time for 10g cold stored parboiled rice was 6 seconds (25%) longer and was considered more palatable, visually appealing and better tasting than freshly cooked medium grain (all P&lt;0.05). Conclusions:. For regular consumers of rice reheating cooked rice after cold storage would lower the dietary glycaemic load and long term may reduce risk for type 2 and gestational diabetes. More trials are needed to identify the significance.

Geographical indication (GI) labeling is used to represent information about specific geographical origins of target products. This study aimed at determining the impact of GI information on sensory perception and acceptance of cooked aromatic rice samples. Ninety-nine participants evaluated cooked rice samples prepared using each of three aromatic rice varieties both with and without being provided with GI information. Participants rated the acceptance and intensity of the cooked rice samples in terms of appearance, aroma, flavor, texture, and overall liking, and also reported how important the GI information was to them. The results showed that consumers rated the cooked rice samples higher in appearance and overall liking when provided with GI information. Interestingly, participants who valued “state-of-origin” information more highly exhibited increased hedonic ratings of cooked rice samples when provided with GI information, but not when no GI information was given. Participants provided with GI information rated flavor or sweetness intensities of cooked aromatic rice samples closer to just-about-right than those without such information. This study provides empirical evidence about how GI information modulates sensory perception and acceptance of cooked aromatic rice samples. The findings will help rice industry, farmers, and traders better employ GI labeling to increase consumer acceptability of their rice products.

Herein, optimized headspace solid phase microextraction with gas chromatography–tandem mass spectrometry (HS-SPME-GC-MS/MS) was used to estimate the 2-acetyl-1-pyrroline (2-AP) in raw and cooked rice samples of ten different traditional and improved varieties. Furthermore, HS-SPME-GC-MS-based volatile profiling was subjected to untargeted analyses to identify major odorants in raw and cooked rice samples, and to understand chemical proximities among volatile profiles. Results showed that 2-AP content was remarkably increased in cooked rice compared to raw. Among the varieties studied, Pusa-1652 (Improved Kala Namak) and Kala Namak-2 were superior in the 2-AP content than Basmati varieties. Additionally, Govind Bhog, Kala Jeera and Jeera-32 had 2-AP content equivalent to or superior to Basmati rice varieties. Altogether, 18 and 22 volatiles were identified in the raw and cooked rice samples studied, respectively. Of these, ethyl butyrate, ethyl 3-methylbutanoate, 2-undecanone, ethyl benzoate, ethyl benzeneacetate, 2-methylnaphthalene, and 1-methylnaphthalene were characteristically detected in the cooked rice. The high amount of 2-ethyl-1-hexanol was uniquely found in raw rice samples, which can be a marker compound for freshly milled rice. Along with 2-AP, butanoic acid and benzoic acid derivatives, phenylethyl alcohol, ethyl 3-hydroxybutyrate, and indole may be responsible for the overall perceived characteristic Basmati-like aroma in cooked rice.

The suitability of 10 different rice varieties cultivated in Benin for parboiling was assessed through physical, chemical and sensorial analysis. Paddy rice samples were soaked at three different water temperatures (60, 70 and 80°C) under laboratory conditions. Using these temperatures, significant differences (p < 0.05) were observed in the chalkiness, hardness and grain homogeneity of the parboiled rice after milling. The paddy rice soaked at 80°C presented the best results: the majority of the parboiled grains were homogeneous (overall mean = 85.16%) and had favorable scores for hardness (overall mean = 8.99 kg) and chalkiness (score =1). In the field, At soaking temperature about 80°C the professional parboilers preferred NERICAL56, BERIS21 and IR841 as the most suitable for parboiling from the investigated rice varieties, due to the grain homogeneity (> 90 %), head rice ratio ( > 86.67 %) and low rate of broken grains after milling (<13.33 %). These three varieties were the most appreciated by the panelists before and after cooking, whereas BL19 and NERICA2 were the least. Findings from this work are important for guiding rice parboiling stakeholders in Benin and other countries in West Africa. NERICAL56, BERIS21 and IR841 were the suitable rice varieties for parboiling to be advised to the processors. To this end, passport data on the varieties suitable for parboiling will be produced and widely disseminated to the stakeholders for rice parboiling.

Carotenoids are a widespread group of fat-soluble pigments, and their major nutritional importance comes from their pro-vitamin A activity and their antioxidant capacity. In this study, two different pumpkin cultivars (Cucurbita maxima, also named `Delica’ and Cucurbita moschata, also known as `Violina’) from the southern Po Delta area were investigated in terms of carotenoid content and the influence of food processing on compositional changes and carotenoid bioaccessibility. Quali- and quantitative determination of carotenoids in sample extracts were performed on a C30 column by means of an online coupled HPLC-UV/Vis-APCI-MS/MS technique. The identification of separated compounds was tentatively achieved by merging (i) chromatographic data, (ii) UV-Vis spectra, and (iii) MS/MS fragmentation spectra. The chromatographic profiles for the two cultivars showed qualitative differences. Two major carotenoids were considered for quantification purposes and further investigations: lutein and β -carotene. Quantification of target carotenoids was performed with external calibration through analytical standards. The concentration of lutein and β -carotene was higher in C. maxima than in the other variety, C. moschata. Carotenoids are susceptible to degradation (isomerization and oxidation) during food processing (i.e., cooking), and the concentration of lutein and β -carotene were monitored in oven-cooked and steam-cooked pumpkins. The steam-cooking process was superior in terms of limiting carotenoid loss. A complete functional profile of pumpkins as a source of carotenoids was gained with the evaluation of their in vitro bioaccessibility and their bioavailability after intake during human digestion. Bioaccessibility of lutein and β -carotene were estimated by an in vitro static digestion model that involved salivary, gastric, and duodenal phases. Bioaccessibility values progressively increased from the salivary to the duodenal phase for both pumpkin varieties and cooking methods. Bioaccessibility of lutein was always lower than β -carotene for both cultivars and for both cooking methods. Bioaccessibility values for lutein and β -carotene changed from 1.93% to 2.34% vs. 4.94% and 8.83% in the salivary phase, from 2.7% to 4.63% vs. 7.83% and 15.60% in the gastric phase, and from 10.04% to 13.42% vs. 25.81% and 35.32% in the duodenal phase. For both target compounds, bioaccessibility in the duodenal phase was more than twice the gastric values, and it underlined that the type of cooking did not influence release from the initial matrix.
