    Feasibility of using konjac glucomannan hydrolysate (KGMH) as prebiotics and wall material for encapsulating probiotics was investigated. Prebiotic activity scores (PASs) were determined for KGMH, inulin, fructooligosaccharides and konjac glucomannan to assess their effectiveness in promoting growth of probiotics and inhibiting enteric mixture. Thermal tolerances of probiotics were also assessed. Lactobacillus rhamnosus L34 and L. acidophilus LA5 exhibited higher PASs and thermal tolerances and were selected for encapsulation; freeze drying and spray drying were used to form and dry encapsulated probiotics. Maltodextrin (MD), soy protein isolate (SPI) and KGMH, either individually or in combination, were comparatively used as wall materials. Freeze drying with SPI and KGMH resulted in highest survival rates for L. rhamnosus L34 (97.92%) and L. acidophilus LA5 (88.94%). In case of spray drying, MD, KGMH and combination of MD and KGMH resulted in drying yields of 55–71%; SPI-containing formula resulted in lower yields (20–23%). Spray-dried probiotics exhibited lower survival rates compared to their freeze-dried counterpart. KGMH, particularly in combination with SPI, emerged as promising material for enhancing probiotics survival during encapsulation.

    This research aimed to investigate the production of low-fat Khao Sao Hai ice cream fortified with synbiotics, soy protein (SP), and chicken breast protein. The study incorporated Sao Hai rice milk into the ice cream formulations and conducted experiments to analyze the physical, chemical, and sensory characteristics. The application of synbiotic powder, SP, and chicken breast protein was explored, with the results indicating significant variations in the nutritional profile. Specifically, ice cream fortified with chicken breast protein exhibited the highest protein content at 4.20 g, followed by SP at 3.92 g, and the control formulation at 1.38 g. In addition, the survival rate of probiotics, represented by Lactobacillus acidophilus LA5, exceeded 98% during storage at −20°C for 21 days, showcasing the successful encapsulation of probiotics with Konjac glucomannan and soy protein isolate. Furthermore, sensory testing revealed that the control formula received the highest consumer acceptance, followed by SP–fortified ice cream. In contrast, chicken breast protein–fortified ice cream received the least acceptance. These findings highlight the potential of Sao Hai rice in creating nutritionally diverse ice cream formulations, offering insights into consumer preferences and the efficacy of different protein sources in enhancing ice cream quality.
