Abstract

The research aims to study the effect of coagulation parameters to the electrophoretical profile of coagulated soybean protein as well as to texture properties and perception. Several coagulation parameters such as type of coagulant, concentration or age of coagulant, and coagulation temperature were studied. The type of coagulant used in this study were GDL (glucono delta Lactone) and tofu whey. The concentrations of GDL were 0.4%, 0.8%, and 1.2% and the ages of tofu whey were 1 day, 2 days, and 3 days. Two coagulation temperatures, 60°C and 80°C, were applied. The results of curd protein profile and texture profile analysis showed that coagulant type and coagulation condition did not affect the electrophoretical profile of soybean coagulated protein. However, the proportion of each subunit was affected significantly. Texture profiles, such as hardness, cohesiveness, and gumminess, were also affected by coagulant type and coagulation condition. Based on the subunits proportion, it can be concluded that 11 S and 7S protein proportions as well as the 11S/7S ratio correlated significantly with the hardness and gumminess of soybean curd made by tofu whey.

Abstract

Enzymatic interesterification of red palm oil (a mixture of red palm olein/RPO and red palm stearin/RPS in 1:1 weight ratio) and coconut oil (CNO) blends of varying proportions using a non-specific immobilized Candida antartica lipase (Novozyme 435) was studied for the preparation of spread stock. The interesterification reaction was held in a batch-type reactor. Two substrate blends were chosen for the production of spread stock i.e. 77.5:22,5 and 82.5:17.5 (RPO/RPS:CNO, by weight) through enzymatic interesterification in three different reaction times (2, 4, and 6 hours). The interesterification reactions were conducted at 60°C, 200 rpm agitation speed and 10% of Novozyme 435. The interesterified products were evaluated for their physical characteristics (slip melting point or SMP and solid fat content or SFC) and chemical characteristics (carotene retention, moisture content, and free fatty acid/FFA content). All of the interesterified products had lower SFC and SMP as compared to the initial blends. The SMP and SFC increased in longer reaction times. The SMP ranged from 30.8°C to 34.9°C. The carotene retention ranged from 74.80% to 81.08%, while the moisture content and FFA content increased in longer reaction times. The interesterified products had desirable physical properties for possible use as a spread stock rich in carotene.

Abstract

The objective of this study was to produce milk powder from Ettawa-crossbred goat milk and subsequently evaluate the quality of the products. The raw material used was Ettawa-crossbred goat fresh milk with total solid, lactose, fat, and protein content of 15.93%, 4.2%, 4.8% and 4.7%, respectively. Milk with final total solid of 17.5% and 20% were prepared for spray drying by adding skim milk powder. Drying was carried out using a spray dryer type Lamp having nozzle size of 0.05 mm with an inlet temperature of 90°C and an outlet temperature of 45°C. Parameters observed were chemical, physical and microbiological qualities. The data showed that milk powder produced from Ettawa-crossbred goat milk had water content of 1.5-1.7%. Further analysis showed that the acidity, proteins, lactose, and fat content were 0.90%, 28.4%, 21.7%, and 22.5%, respectively. The physical analysis showed that milk powder produced from Ettawa-crossbred goat milk had a higher wettability score (143 seconds) as compared to that of commercial products (29 seconds), a higher sieve test score (0.6 g vs 0.004 g), but similar index of insolubility (1.4 ml vs.1.6 ml). The microbiological analysis showed that the Total Plate Count (TPC), Enterobacteriaceae (EB) and presumptive coliforms increased during storage either in refrigerator or room temperature. The increase in TPC, EB and coliforms was substantially higher when products were kept at room temperature than in refrigerator. In conclusion, Ettawa-crossbred goat milk powder had a good nutrition quality, but still need improvement for the physicochemical characteristic including wettability and nutritional enrichment for vitamins and minerals by means of fortification.

Abstract

Crosslinked-sago-starch-phosphate (SgP) has been successfully synthesized from native sago starch (Sg) and Na2HPO4-NaH2PO4 in an acidic condition. The compound was designed as bioadsorbent for removing Hg(II) inside human digestion tract as shown by in vitro test. The bioadsorption followed pseudo-second order of reaction kinetic and Freundlich equation as chemisorption. As a result, 21% of Hg(II) was removed at pH of 6.80 and reached the isothermal equilibrium of the bioadsorption at pH of 5.80 and 8.60 for 29.95% and 31.39%, respectively. The result showed that SgP is more feasible than activated carbon to be used as bioadsorbent in removing Hg(II) in human digestion tract as proved by in vitro system.

Abstract

The objective of this research was to improve the quality of dried corn noodle through the optimization of processing condition using a cooking-forming extruder and the addition of monoglyceride. The process conditions was optimized using Response Surface Methodology (RSM) based on two processing parameters i.e., extruder temperatures (80-90°C) and screw speeds (75-125 rpm). The optimum condition of cooking extrusion was obtained at 90°C and 75 rpm. However, the noodle firmness and stickiness were unsatisfactory. The use of 1% Glyseryl Mono Stearate significantly improved the quality of the noodle with acceptable firmness, elasticity, and elongation. However, the cooking loss and stickiness were still high.

Abstract

The objectives of this research were to study the characteristics of mango chips drying using a double plated solar collector. The materials used were sliced mangoes with the thickness of 3, 6, and 8 mm. The equipments used for this research were double plated solar collector, thermocouple, digital balance, thermometer, vacuum oven, and desiccators. The research parameters included the rate of heat energy absorbed by the double plated solar collector, the heat energy losses, the efficiency of the double plated solar collector and the moisture content of the chips. The results of this study suggested that the use of double plated solar collector could increase the temperature and the amount of heat energy, thus speed up the drying process of the mango chips. The energy needed to evaporate the moisture content in mango decreased in proportion to the increase in drying time. The difference in mango chips’ thickness resulted in different decrease rate in water content until it reached a constant state. The efficiency of the double plated solar collector was 77.82%.

Abstract

Some of Lactobacillus species isolated from breast milk are known to have antimicrobial activities, including against Escherichia coli. The aims of this study were to evaluate the antimicrobial activity of Lactobacillus species isolated from breast milk against enteropathogenic Escherichia coli strain K1.1 and the effectiveness of the Lactobacillus isolates to prevent diarrhea on rats (Sprague Dawley). The infective dose of E. coli K1.1 to induce diarrhea without causing death were also determined. Based on the antimicrobial activity there were three isolates of Lactobacillus that exhibited good inhibition againts E. coli K1.1, i.e. Lactobacillus rhamnosus R14, L. rhamnosus R23, and L. rhamnosus B16. Determination of E. coli infective dose showed that 108 CFU of E. coli K1.1 was sufficient to induce diarrhea on rat without causing death. The number of diarrhea rats and severity level in group treated with L. rhamnosus were lower than groups untreated with the Lactobacilli. This study showed that the three L. rhamnosus isolated from breast milk were able to prevent diarrhea due to infection of E. coli K1.1 when the Lactobacillus was regularly introduced prior to infection. L. rhamnosus R23 showed the best capabilities of preventing diarrhea in rats as compared to two other isolates of Lactobacillus. The incidence of diarrhea correlated with the number of lactobacilli in the feces. However when the period of diarrhea ceased, there were no difference in total lactobacilli and E. coli in the caecum, colon and feces between rats treated with L. rhamnosus and the control. This finding revealed the L. rhamnosus isolated from breast milk were potential for prevention of diarrhea when consumed regularly.
