Pitaya commonly known as dragon fruit is very popular of its intense color, constituent minerals, vitamins,and antioxidant properties. In this study, physiochemical properties of whole pitaya fruit powder as influenced by 2different maltodextrin concentrations (20 and 30%) and 4different inlet temperatures (145, 155, 165, and 175oC) were carried out. As inlet temperature increased moisture content and water activity decreased and this change was apparent at high concentration of maltodextrin. The best spray drying condition in relation to betacyanin content was 155oC inlet temperature and 20% maltodextrin concentration. Concerning the flowability, all factors and their levels resulted in poor flowing powder. From nutritional point of view, pitaya fruit powder was found rich in protein, fat, ash, fiber, and antioxidant. This study indicated that the pitaya fruit powder produced from whole pitaya fruit has potential to use as natural coloring agent and a health supplement.

Objectives: To 1) report prevalence of ‘osteosarcopenia’ (OS) and osteosarcopenic obesity (OSO) entities using evidence-based diagnostic techniques and definitions, 2) examine if OSO offers additional predictive value of functional decline over its components, and 3) identify associated factors in a multi-racial Southeast Asian population. Methods: We performed a cross-sectional study of a representative sample of 542 community-dwelling adults (21e90 years old), and assessed anthropometry, cognition, functional performance, and selfreport sociodemographic, health and lifestyle questionnaires. Low muscle mass, and the Asian Working Group for Sarcopenia (AWGS) 2019 criteria, were used to assess sarcopenia. Obesity was defined using percentage body fat and fat mass index. Osteopenia/osteoporosis was determined using lumbar spinal bone mineral density. Associated factors were examined using logistic regression, and OSO’s value investigated using linear regressions with functional performance. Results: OS and OSO prevalence were 1.8% and 0% (21e59 years), 12.9% and 2.8% ( 60 years), 17.3% and 4.1% ( 65 years), and 25.5% and 7.0% (75 years), respectively. OSO entity as defined was not a significant predictor (P > 0.05) and did not improve explanations for functional decline over sarcopenia or sarcopenic obesity. Age, sex, race and body mass index (BMI) were associated with OS, while age, sex, race and alcoholism were associated with OSO. Conclusions: Our results do not support OSO as a distinct entity in relation to functional decline. Aside from biological age, sex, and race, amenable lifestyle factors such as BMI and alcohol intake are important variables that can influence the co-existence of osteopenia/osteoporosis, sarcopenia and obesity.
