Abstract

Isolation and the physicochemical properties of rice bran protein concentrate (RBPC) produced from unstabilized and heat-stabilized Pandanwangi and Ciherang rice bran were studied. Rice bran stabilization process optimization done on previous research resulted in the extrusion conditions at a temperature of 130.96oC and screw speed 26.65 Hz. Kjeldahl analysis showed that protein content of unstabilized rice bran protein concentrates (URBPC) and stabilized rice bran protein concentrates (SRBPC) of Pandanwangi and Ciherang were 60.76%, 61.38%, 60.19%, and 60.23% respectively. Amino acid composition showed that polar amino acid composition of RBPC Ciherang was higher than that in Pandanwangi leading to its solubility. The protein percentage of acid-soluble glutelin of Pandanwangi was higher than that in Ciherang rice bran protein concentrate. The molecular weight were in range from 11.19 to 60.29 kDa. Glutelin differentiated into α-glutelin (30-39 kDa) and β-glutelin (19-25 kDa). The  RBPCs from two varieties had similar denaturation temperatures (77.22 - 77.99oC) with enthalpy ranged between 109.72 J/g and 200.98 J/g. Foaming stability and emulsion activities had similiar pattern with solubilities profile and showed no significant difference between varieties (p> 0.05). This finding shows potential protein concentrate of  both heat-stabilized and unstabilized rice bran as food ingredient. Keywords: Heat-stabilized rice bran, rice bran protein, physicochemical properties

Abstract

The objective of this research was to observe the quality changes of instant corn porridge during storage and to estimate its shelf life. Parameters that tested to determine the shelf life of instant corn porridge were TBA (Thio Barbituric Acid) number, color change, and the organoleptic characteristic, including aroma and color. The estimation of shelf life was done by storing samples in the incubator with three different acceleration temperatures (35oC, 45 oC, and 55 oC) for six weeks. Based on the result of this research, the critical parameter to estimate shelf life was the aroma of instant corn porridge powder. The critical value of instant corn porridge powder aroma was 6, which was described as slightly rancid. Arrhenius equation that used to estimate the shelf life of instant corn porridge was ln k = -1808.4(1/T) + 2.932 with the activation energy of 3591.4824 cal/mol. The tested instant corn porridge had 82 days of shelf life at 28oC of storage temperature.

Abstract

Corn is a carbohydrate that can be processed into corn-rice analog. The product has acceptable physical and sensory qualities. However, its quality changes during storage and shelf-life has not been reported. The objective of this research was to evaluate quality changes of corn-rice analog during storage and to predict its self-life using accelerated shelf-life testing (ASLT) applying Arrhenius model. Corn-rice analog was stored at 35, 45, and 55oC, and periodically analyzed for 35 days. The analyses included the changes of thio barbituric acid (TBA) number, colour, and sensory quality (rancid odor and color intensity). The TBA number did not inconsistently change during storage. The significant quality changes was due to colour changes (L, a, and b values) of corn-rice analog and rancid odor and color by panelist for corn rice analog before and after cooking. The b value parameter was the most critical quality parameter. Based on its b value, the rice analog had shelf-life of 3 month 17 days at room temperature (25oC).

Abstract

Coconut (Cocos nucifera L.) is a multipurpose plant, either for food or non-food purposes. Coconut meat texture was various, depending on the age of coconuts. This was an obstacle in the coconut beverage industry for using natural coconut meat. The purpose of this study was to create an acceptable modified coconut meat formula, with physical characteristic in accordance with the real coconut meat. The modified coconut meat consisted of real coconut meat, coconut milk, water, and agar which percentages are 71.30, 16.13, 12.10, and 0.26%, respectively. The percentages of carrageenan and konjac for each formula was F1 (0.00:0.23), F2 (0.23:0.00), F3 (0.03:0.20), F4 (0.20:0.03), F5 (0.10:0.13). To find the most preferable formula, a hedonic test was done with tested parameters as follow: taste, aroma, texture, visual appearance and overall. F5 formula was the most preferable formula. Physical analysis of F5 with texture analyzer produces a hardness value of 240.50 gf which is significantly different from real coconut meat control (p≤0.05), ie 325.80 gf. While the value of F5 gel compactness was not significantly different from control (p≤0.05) indicated by the area of F5 (705.73 gs) and control (695.80 gs). Analysis of whiteness with chromameter showed that all samples were not significantly different (p≤0.05) as compared to the control. Result of gel stability observation showed that chart of F5 formula was tend to descend upon time (50.34 to 45.75 g), while the chart of control was ascend at start, but tend to stable upon time (50.78 to 59.24 g). The result of proximate analysis showed that, F5 has 92.06±0.06% water content, 0.25±0.00% ash content, 2.54±0.52% fat content, 0.37±0.0% protein content, 0.17±0.02% crude fiber content, and 4.62±0.56% carbohydrate content.

Abstract

Banggai yam (Dioscorea sp) has many varieties, which is locally cultivated and consumed by people in Banggai, Central Sulawesi. Banggai yam can be processed into flour and applied as an ingre-dient in analogue rice. This study aimed to evaluate the physical and chemical composition, total phenol and antioxidant activity of banggai yam flours, and the physical properties, total phenol and antioxidant activity of their analogue rice. Five varieties of banggai yams (Harum, Banggai, Pasus, Doso, and Penus) were compared. Banggai yam flours were composed of moisture (12.21-12.74%wb), ash (2.18-2.75%db), protein (10.41-11.68%db), fat (1.05-3.38%db), and carbohydrate (83.22-85.77%db). All banggai flours had different color (L, a, and b values) intensities, and contained starch (65.38-68.40% db) with amylose content of 38.96-45.09% (db). The total phenol ranged from 30.48-116.90 mg GAE/ 100 g, and showed antioxidant activity (58.71-89.50% inhibition). The pasting profile varied among five yam flours. The initial pasting temperatures of banggai yam flour were relatively high (82.5-83.7°C). All banggai yam flour increased in viscosity up to a peak and experienced slight viscosity breakdown during the heating phase, as well as showed a setback viscosity during cooling phase. Rice analogue of yam flours made by extrusion technology had a relatively low bulk density (0.47-0.56 g/mL), and required a long cooking time (7-9 minutes). The rice analog had different levels of total phenol and antioxidant activities. The level of total phenol and antioxidant activity of analogue rice from Harum yam showed the highest compared to those other analogue rice.

Abstract

AbstrakBekatul dari hasil samping penggilingan padi memiliki komponen gizi dan non-gizi. Proses fermentasi pada bekatul diketahui dapat meningkatkan komponen fenolik dan aktivitas antioksidannya. Penelitian ini menggunakan bekatul yang difermentasi dengan kapang Rhizopus oligosporus selama 72 jam dan diformulasikan sebanyak 15, 20, dan 25% ke dalam sereal sarapan jagung. Bekatul tanpa fermentasi juga dibuat sebagai pembanding. Karakteristik fungsional yang berupa aktivitas antioksidan, kadar total fenol, serat pangan, mutu fisik yang berupa derajat pengembangan (DP), indeks penyerapan air (IPA), kelarutan air (IKA), kekerasan dan kerenyahan, serta mutu sensori sereal sarapan dianalisis dengan menggunakan rancangan acak lengkap dua faktor dan diuji lanjut dengan Duncan Multiple Range Test. Hasil penelitian menunjukkan bahwa penambahan bekatul fermentasi mampu meningkatkan aktivitas antioksidan dan kadar total fenol, namun memberikan penerimaan sensori yang lebih rendah dibandingkan formula sereal sarapan yang lain. Kesimpulannya, substitusi dengan 25% bekatul tanpa fermentasi dalah yang paling disukai berdasarkan analisis warna, aroma, rasa, dan tekstur. Sereal sarapan dengan formulasi tersebut memberikan nilai DP, IPA, dan IKA yang spesifik dan memberikan tingkat kekerasan dan kerenyahan yang dapat diterima panelis, serta menunjukkan aktivitas antioksidan, kandungan total fenol dan serat pangan yang tergolong tinggi.Functional, Physical and Sensory Characteristics of Corn Breakfast Cereals Substituted by Fermented Rice BranAbstractRice bran as a by-product of rice mills contains a relatively high nutritious components, such as phenolic compounds. Fermentation process in rice bran may increase phenolic compounds and antioxidant activity. In this study, fermented rice bran using Rhizopus oligosporus for 72 hours were formulated into corn-based breakfast cereals at the concentration of 15, 20, and 20%. Non fermented rice brand was also used as a comparison. The functional characteristics that consisted of antioxidant activity, total phenol, and dietary fiber; physical quality, i.e. degree of expansion (DE), water absorption index (WAI), solubility index (SI), hardness and crispness; and sensory quality were analysed using a two-factor randomized experimental design followed by Duncan Multiple Range Test. As a result, fermented rice bran yielded less acceptable breakfast cereals than that of a non-fermented cereal, although the antioxidant activity and total phenol increased along the fermented rice brand. As a conclusion, substitusion with 25% non-fermented rice bran was the most accepatable in terms of color, aroma, taste and texture compared to other formulations. The formulated breakfast cereal had specified DE, WAI and SI, hardness and crispness, as well as showed high values of antioxidant activity, total phenol, and dietary fiber.
