Starch is one of the most used polysaccharides in the food industry because is an excellent raw material to modify the texture and consistency of food. Also, is the main source for energy storage in horticultural products. The starch from soursop fruits can be used as an alternative source with functional properties and a wide field of application in the food industry. The use of emerging technologies such as ultrasound-assisted extraction has improved sensory attributes and functional properties. To the best of our knowledge, extraction of starch by ultrasound from soursop fruits has not to date been documented. Therefore, the objective of this study was to characterize the functional properties of soursop fruit starches by ultrasound-assisted method and determine the presence of acetogenins. Three times (10, 15 and 20 minutes) and three ultrasonic amplitudes (UA) of 20, 30 and 40% for the ultrasound-assisted extraction were used. Total yield, gelatinization temperature, water absorption and solubility index, swelling index, amylose and amylopectin content, presence of acetogenins and starch granule morphology were recorded. The highest extraction yield (ultrasound) was reached using 10 min and 40% UA (6.34%). For the gelatinization temperature, 10 min and 30% UA (82.33°C) were the best conditions. Water Solubility Index (WSI) values of 6.13 ± 0.00% using 10 min and 20% UA were recorded. Water Absorption Index (WAI) as well as Swelling index (SI) values of 3.34 ± 0.12% and 3.26 ± 0.00% were obtained by conventional extraction, respectively. Starch granules morphology showed different size with circular shapes and truncated geometries. Finally, positive qualitative results for the presence of acetogenins by all the extraction methods were obtained.

Flaxseed (Linum usitatissimum L.) has several health-promoting applications as dietary food ingredient supplementation, owing to presence of high quality of oil, polyunsaturated fatty acids, high dietary fiber and protein contents. The presence of different anti-nutritional components, for example cyanogens (HCN) and tannins in meal, limits its application for food purposes. The study was conducted to observe the effect of ultrasound-assisted extraction on polysaccharide gums (PSG) yield using response surface methodology. The selected variables were sonication temperature (°C), water to meal ratio, sonication amplitude level (%), sonication pH, and sonication time (min). Ultrasound-assisted extraction significantly reduced the anti-nutritional components like HCN and tannins. The extracted PSG yield from partially defatted flaxseed meal (PDFM) samples varied to a minimum of 7.24% to a maximum of 11.04% when extraction temperature (°C) and amplitude level (%) varied from −1 to +1 and keeping all other variables constant at mean value. Physiochemical and functional properties of extracted PSG were studied. Yoghurt with different treatment combinations were prepared by supplementing flaxseed-derived PSG as stabilizer ranging from 0.25% to 1.5%, keeping baseline samples without PSG as control. Functional properties of PSG-supplemented yoghurt such as pH, syneresis, and viscosity were determined to assess the influence of PSG supplementation on yoghurt quality. In the organoleptic behavior of PSG-supplemented yoghurt, no adverse effect on the flavor have been observed, but the textural properties vary significantly among different treatments. Overall, the acceptability of 1% PSG-supplemented yoghurt was significantly higher than other treatments.
