Summary: Gac (Momordica cochinchinensis Spreng.) is a tropical vine originating from South and South-East Asia. Gac fruit has traditionally been used in Asia to provide red colour for cuisines and enhance visional health. Recently, Gac fruit has emerged as a potential source of carotenoids, especially lycopene and ß-carotene. Carotenoids and other identified bioactives from this fruit including phenolics, flavonoids and trypsin inhibitors are associated with many beneficial bioactivities such as antioxidant, anticancer and provitamin A activities. In addition to the traditional utilisation, commercial products like Gac powder and Gac oil have been manufactured as natural colourants and medicinal supplements. This paper is a review of the scientific literature on the nutritional composition, biological activities and processing of Gac fruit.

The objective of this study was to optimise the spray drying conditions for the encapsulation of Gac oil using response surface methodology. Results indicated that the corresponding response surface model was sufficient to describe and predict encapsulation efficiencies (EEs) in terms of the oil, ß-carotene, lycopene, encapsulation yield (EY), moisture content (MC), water solubility index (WSI) and peroxide value (PV) with R2 of 0.92, 0.91, 0.89, 0.85, 0.89, 0.98 and 0.97, respectively. Under optimal conditions (inlet and outlet temperatures of 154 and 80°C), the response variables including the EEs of the oil, ß-carotene, lycopene, EY, MC, WSI and PV were predicted and validated as 87.22%, 82.76%, 84.29%, 52.78%, 4.90%, 90.29% and 4.06meq/kg, respectively. Furthermore, physicochemical, reconstitution and colour properties of the optimally encapsulated powder were also determined. It was concluded that this powder containing high content of unsaturated fatty acids, ß-carotene and lycopene, and having the attractive red-yellow colour can be used as nutrient supplement and natural food colourant. © 2014 Elsevier B.V.

The objective of this study was to optimize the wall material concentration and the oil load on the encapsulation of Gac oil using spray drying by response surface methodology. Results showed that the quadratic polynomial model was sufficient to describe and predict encapsulation efficiencies in terms of oil, ß-carotene, lycopene, peroxide value (PV), moisture content (MC), and total color difference (¿ E) with R 2 values of 0.96, 0.95, 0.86, 0.89, 0.88, and 0.87, respectively. Under optimum conditions (wall concentration of 29.5 % and oil load of 0.2), the encapsulation efficiencies for oil, ß-carotene, lycopene, PV, MC, and ¿ E were predicted and confirmed as 92 %, 80 %, 74 %, 3.91 meq/kg, 4.14 % and 12.38, respectively. The physical properties of the encapsulated oil powders obtained by different formulations were also determined. It was concluded that the protein-polysaccharide matrix as the wall material was effectively used for spray-drying encapsulation of Gac oil. © 2014 Copyright Taylor and Francis Group, LLC.

The application of high pressure for processing fish muscles has showed a great potential on improving the physicochemical, microbial and sensory quality of fish muscles. High pressure results in the inactivation of micro-organisms and autolytic enzymes and lead to an extension of fish muscles shelf life. High pressure inhibits the formation of putrefactive compounds and maintains the hardness of fish muscles, resulting in higher sensory quality compared to untreated muscle over storage time. However, the discolouration, cooked appearance and lipid oxidation are the drawbacks that could limit the application of high pressure on fish muscles. Besides, pressure-induced gelling and high-pressure freezing/thawing of fish muscles are the main areas being investigated intensively to obtain the benefits of high-pressure processing on fish muscles. © 2014 Springer Science+Business Media New York.

The aims of this study were to develop optimal conditions for decaffeination and spray drying procedures to produce decaffeinated and high caffeine powders from green tea (Camellia sinensis). Blanching the tea leaves with water at 100. °C for 4. min at a water-to-tea ratio of 20:1. mL/g removed 83% of the caffeine while retaining 94% of the catechins. The optimal spray drying conditions, which gave the highest yield of green tea powder and the highest concentrations of the naturally occurring epistructured catechins were found to be 180. °C for the inlet temperature and 115. °C for the outlet temperature. Using these optimal conditions, a decaffeinated green tea powder (7 mg/g caffeine) and a high caffeine powder (95. mg/g) were produced. These two green tea powders had excellent physical properties and could be used as instant teas by consumers or utilized in the food, cosmetic and nutraceutical industries. © 2012 Elsevier B.V.

The effects of Gac oil extraction conditions including microwave power, microwave time, steaming time and hydraulic pressure on extraction efficiency (EE), and b-carotene and lycopene contents were studied. It was found that the EE, and b-carotene and lycopene contents could be enhanced by suitable extraction conditions. Microwave drying was found to be better than air drying for pretreatment. Moisture content after drying and steaming between 8% and 11% (wt/wt) were best for pressing. Results showed that the most suitable conditions for Gac oil extraction from 900 g samples were microwave power of 630 W, microwave time of 65 min, steaming time of 20 min and hydraulic pressure of 170 kg/cm2. Under these conditions, the highest EE of 93% was achieved while Gac oil contained the highest content of b-carotene and lycopene at 140 and 414 mg/100 mL, respectively.

The effect of l-ascorbic acid (l-AA) on free sulfhydryl concentration (SH) was evaluated in soy-wheat composite dough from 100-500 (g/kg) soy flour substitution for wheat flour. Raw soy flour (RSF) and physically modified soy flours (PMSF1 and PMSF2) were used for the preparation of the composite dough with wheat flour. The two physically modified soy flours were prepared by steam flushing (PMSF2) and water boiling (PMSF1) of raw soy beans before flour preparation. Using a timer, dough blends were manually mixed (at approximately 60 rpm) to dough development time after which, dough was sampled for the estimation of free SH groups. l-AA (0.05% w/w) was mixed with the dough after dough development and the dough was sampled after 1 h of resting the dough. The results showed that l-AA (0.05% w/w) acted as a reducing agent by increasing SH levels in all soy-wheat dough blends (P < 0.05). After 1 h of resting, soy-wheat composite dough without l-AA had lower concentrations of SH than that with l-AA. A positive correlation was shown between soy flour concentrations and SH concentration before and after dough resting. A negative correlation existed between l-AA consumption and SH concentration for RSF-wheat, PMSF1-wheat and PMSF2-wheat doughs. The results indicated that soy flour weakened wheat flour dough by increasing SH concentration and that l-AA could have a synergistic effect on the reduction of gluten proteins and thus weakening the dough. © 2005.

2007Bui VA, Nguyen MH, Muller J, 'The energy challenge of direct contact membrane distillation in low temperature concentration', Asia-Pacific Journal of Chemical Engineering, 2 400-406 (2007)

Direct contact membrane distillation (DCMD) was operated at low temperatures from 25 to 40°C to suit the purpose of thermally concentrating sensitive liquid foods, especially fruit juices to high solid content concentrate with most of the quality attributes preserved. A lab scale DCMD unit has been set up at the Centre for Plant and Food Science, University of Western Sydney. Hollow fibre modules (HFM) using five types of fibres of polyvinylidene fluoride (PVDF) and Halar material, with mass transfer areas ranging from 281 to 573 cm2 were employed. Experiments for concentration of glucose solutions from 30 to 60% (w/w) were carried out. Results indicated that not only the operating conditions were important, but also the membrane properties. It was found that Halar fibres were performing 2-3 times better than PVDF fibres in term of removing water from the feed, and 3-4 times better in term of energy saving. Results also showed that an increase of the feed inlet temperature from 25 to 40°C improved the mass flux up to 6 times and energy efficiency (EE) up to 2.5 times depending on the feed concentration. With flux up to 2.88 kg m-2 h-1 for PVDF and 5.83 kg m-2 h-1 for Halar fibres when concentrating 30% glucose solution at 40°C, DCMD appeared to be an attractive concentration technique, when product quality is the priority. However, with EE from as low as 2.1-14.9%, PVDF fibres employed in the study seemed not to be very suitable for DCMD liquid food concentration under low temperature condition. DCMD in Halar fibres with EE up to 45.6% still encounters the challenge of energy and could only be cost competitive to osmotic distillation and evaporative concentration when cheaper energy sources or heat recovery measures are employed. © 2007 Curtin University of Technology and John Wiley & Sons, Ltd.

Farinograph and extensograph were used to study the effect of l-ascorbic acid and physical modification of soy flour on rheological properties of soy-wheat composite dough at various ratios up to 50% soy flour. Soy-wheat composite dough made from physically modified soy flour (PMSF) exhibited higher resistance to extension (Rm), greater tolerance to mixing, better mixing stability, higher water uptake and water absorption than the soy-wheat composite dough from raw soy flour (RSF). l-Ascorbic acid at 250 and 500 ppm improved Rm, (P < 0.05) of the dough made from the RSF and PMSF at 50% soy flour substitution for wheat. The same concentration of l-ascorbic acid decreased extensibility of the soy-wheat dough after 135 min of resting in both models (P < 0.05). © 2005 Elsevier Ltd. All rights reserved.

Cottage cheese whey has been a problem waste as it is dilute, salty and acidic. The use of nanofiltration has been applied to cottage cheese whey to concentrate its solids content four fold, while removing about three-quarters of the sodium and potassium salts and some acid. This desalted nanoconcentrated whey was found to be quite stable under refrigeration for up to 6 weeks. It could then be considered as a recovered by-product for use as an ingredient in dairy and other food products. A preliminary process economics case study was carried out for a plant producing 30,000 l/day of cottage cheese whey. The capital cost required was estimated as $700,000. The payback period was calculated to be less than 10 months. © 2003 Elsevier Science Ltd. All rights reserved.

1999Chuaprasert S, Douglas P, Nguyen M, 'Data reconciliation of an agitated thin film evaporator using AspenPlus', Journal of Food Engineering, 39 261-267 (1999)

Process measurements made in chemical plants often do not satisfy material and energy balances due to random or possibly gross errors in the measuring device readings. Data reconciliation is a method of adjusting process measurements in a weighted least squares sense in order to satisfy the process constraints as well as minimize the difference between the process variable and the measurement of the process variable. Steady state simulation packages equipped with optimization routines can be used effectively to perform data reconciliation and parameter estimation using existing built-in models which automatically satisfy mass and energy balance constraints. The time required to develop a data reconciliation problem can be significantly reduced by using these packages without sacrificing the quality of the results. Data reconciliation was performed on data from a pilot plant Agitated Thin Film Evaporator (ATFE) for concentrating sugar syrup using the AspenPlus simulation system. An AspenPlus simulation of the ATFE was developed using the built-in rigorous heat exchanger model, Heatx, and the rigorous two phase flash model, Flash2. The optimization was carried out using the built-in SQP, (Sequential Quadratic Programme), optimization routine. Data reconciliation improved the fit between the experimental data and the simulation model from between 30% and 98% as well as guaranteeing that the adjusted process measurements satisfy the mass and energy balances. The time required to develop the AspenPlus simulation and data reconciliation was about 1 h whereas a first principles simulation model developed using the programming language such as Fortran or C would take much longer to develop.

Quenching of curcumine fluorescence by thionine, both immobilised in cellulose acetate occurs in accordance with the Förster mechanism of energy transfer. The rate constant of energy transfer for this donor - acceptor pair is found to be 9.4 × 109 L-1 mol s1 with Ro = 37±1 Å. When this donor - acceptor pair is excited in the presence of oxygen, singlet oxygen (1¿gO2) is also produced as a consequence. The application of this process of singlet oxygen sensitization for scavenging of oxygen is demonstrated.

1996Maloba FW, Rooney ML, Wormell P, Nguyen M, 'Improved oxidative stability of sunflower oil in the presence of an oxygen-scavenging film', JAOCS, Journal of the American Oil Chemists' Society, 73 181-185 (1996)

The oxidative stability of sunflower oil (SFO) was measured during storage at 23 and 37°C in the presence of a novel oxygen-scavenging film that contained polyfuryloxirane (PFO). Commercially refined and deodorized SFO was stored in a lighted room in sealed transparent packages containing either PFO film or an antioxidant, 0.02% butylated hydroxytoluene (BHT). Oxidative stability was evaluated by determination of peroxide values and gas-chromatographic measurement of headspace hexanal, SFO stored in the presence of the oxygen-scavenging film was more stable than oil stored without the film, or than film stored with 0.02% BHT. The PFO film scavenges oxygen through energy-transfer sensitization of singlet oxygen. The film is doped with eosin and the naturally-occurring dye, curcumin, which absorb over a wide range of visible wavelengths. Curcumin transfers its absorbed energy to eosin, which sensitizes the production of singlet oxygen. The singlet oxygen is scavenged by PFO. The use of two dyes increases the efficiency of the sensitization process, reducing the illumination time and intensity required for effective oxygen scavenging.
