Garcinia cambogia (Malabar tamarind) is a native plant of Southeast Asia which its dried rind has been extensively employed as an ingredient of the traditional food seasoning and dietary supplements for weight loss. This study aims to prepare the malabar tamarind fruit extract in form of stable foam mat. The development was performed using 1% w/v hydroxypropyl methylcellulose (Methocel K15M) and maltodextrin as foaming agent and foam carrier respectively. The contents of foaming agent were varied: 10, 20, 30, 40 and 50 percent and the contents of foam carrier were also varied: 20, 30, 40 and 50 percent. Highest content of foamed powder received when 50 percent of foaming agent was used and the content of foamed powder was much higher when maltodextrin was added. However, maltodextrin higher than 20 % can cause the disruption of foam formation and resulting in lower yield of foamed powder. Thus malabar tamarind instant powder could be prepared by foam-mat method using 50 percent of 1% methocel and 20 percent of maltodextrin as foaming agent and foam carrier, respectively. Foamed powder of malabar tamarind extract obtained after drying with hot air oven at 70 °C was bulky and stable.

The protein foaming agent in alfalfa leaves responsible for foam formation in the rumen in pasture bloat has been isolated from protein extracts by agar gel filtration. The isolated protein showed a characteristic absorption at 280 and 260 mμ. The ultracentrifuge and electrophoretic schlieren patterns indicated that the protein was homogeneous. The sedimentation coefficients of the protein and alfalfa leaf macerate identified it as 18-S protein. This is believed to be the first report identifying 18-S protein as the cause of pasture bloat.

American elderberry (Sambucus canadensis) is a plant native to North America with anthocyanin-rich fruits. Our objective was to investigate the effects of cultivar and ripeness on the phytochemical characteristics of its fruits and the corresponding color performance. Cultivars ‘Adams’, ‘Johns’, ‘Nova’, ‘Wyldewood’, and ‘York’ were examined for their °Brix, pH, anthocyanin (pH-differential method), and phenolic content (Folin-Ciocalteau method). Extract composition were analyzed by uHPLC-PDA-MS/MS. Color and spectra were determined using a plate reader. All characteristics evaluated were significantly affected by ripeness and cultivar, except for °Brix and total phenolic content, which did not vary significantly among cultivars. Most anthocyanins (63–72%) were acylated with p-coumaric acid, with cyanidin-3-(trans)-coumaroylsambubioside-5-glucoside the most predominant. The proportion of acylated anthocyanins was the only characteristic evaluated that decreased during ripening (from 80 to 70%). Extract from fully-ripened fruits exhibited red (lvis-max ~520 nm) and blue hues (lvis-max ~600 nm) at acidic and alkaline pH, respectively. Extracts from half-ripe fruit rendered yellowish tones and overall dull color. C-18 semi-purified extracts displayed higher color saturation (smaller L* and larger C*ab) than crude extracts. The vibrant and broad color expression of fully-ripened fruit extract, especially after C-18 purification, suggests this North American native plant as a promising natural colorant source.

Obesity is a major health concern worldwide, and it is leading to worsening disease morbidity and mortality. Herbal supplements and diet-based therapies have attracted interest in the treatment of obesity. It is known that Garcinia cambogia (GA) and mulberry leaf, which contain polyphenols, have anti-obesity activity. Herein, we developed a combined tablet consisting of GA extract and bioconverted mulberry leaf extract (BMUL) using a statistical design approach. The ratio and amount of sustained polymers were set as factors. In the cell study, the combination of GA and BMUL showed synergistic anti-obesity activity. In a statistical model, the optimized amounts of hydroxypropyl methylcellulose 2208 (HPMC 2208) and polyethylene oxide 303 (POLYOX 303) were 41.02% and 58.98%, respectively. Additionally, the selected ratio of microcrystalline cellulose (MCC) was 0.33. When the release, hardness, and friability of the GABMUL tablet were evaluated, the error percentages of the response were lower than 10%. This indicates that the GABMUL tablet was successfully prepared.

Moisture content of tomato (Licopersicon esculentum Mill.) is very high, so easily damaged due to physical impact, enzyme and microbes activity. Further processing is necessary in order to improve shelf life, one way is drying method. This work studied the effect of foaming agent and cake thickness in tomato drying using tray dryer at various temperatures. Foaming agent is used to convert the material into foam, so that the drying temperature can be set relatively low to preserves color, aroma and nutrient composition of the material. The tray dryer is used, because it is simple and the operation cost is relatively cheap. In this work, tomatoes were sliced, crushed for 10 minutes using blender, separated from the seeds and residues with a 60 mesh sieve, and then mixed with dextrin and foaming agent Tween 80 each by 5% weight respectively. Each mixture was blended for 10 minutes. The tray dryer was filled with hot air at 2.0 m/sec with temperature variation of 40, 50, 60 and 70ºC and cake thickness variation of 2 and 4 mm. The results obtained, drying at 50° C is faster than 40º C, while 50 to 70º C is relatively the same. The thicker the cake, the slower the drying time. Performance of foaming agent Tween 80 compared to chemical foaming agent is a natural egg white powder. Drying with a foaming agent Tween 80 faster than egg white powder. Keywords: cake thickness; foaming agent; tomato; tray dryer

Insulation effect and mechanical performance of foam glass depend, to a large extent, on foam structure. Hence understanding foam formation is not only a problem of significant fundamental interest but also of tremendous practical impact. In this paper, foam growth was modeled comparing to grain growth theory in sintering. TG-DTG analysis of carbon black indicated that pre-oxidation took place prior to foaming temperature. Furthermore effects of heating rate and particle size of carbon black on foam structure have been taken into account. Several borosilicate foam glasses were fabricated by powder sintering process at different heating rates using carbon black of different particle sizes as foaming agent, respectively. It was found that increasing the heating rate tended to decrease the pre-oxidation of carbon black resulting in inhomogeneous foam distribution. Foam structure of sample heated at a rate of 8°C/min using carbon black with particle size of 0.15mm was optimal.

In view of changing of food habits of local communities of Uttarakhand Himalaya, a study to document the native plant genetic resources of fruit importance and products was conducted. Wild edible fruits were documented through scheduled interviews. With the help of respondents the questionnaires were filled up. After conducting the survey in the Bharsar and Adjoining area of Pauri district, the plant species of fruits importance were identified and a large number of traditional food items were enumerated. The relationship between plant species of food products importance and sustainable livelihood was also discussed.
