This study consisted of three sub-studies including 1) development and evaluation of facial serum from Thai rice on skin moisture, elasticity, oiliness, and melanin in healthy participants 2) development and evaluation of facial mask from Thai rice on skin moisture, elasticity, oiliness, and melanin in healthy participants and 3) development and evaluation of ready-to-drink jelly from Thai rice on controlling blood glucose and endurance time in healthy participants.

Study 1: 30 male and female participants, age 30-50 years will be randomly applied with facial serum producing from either 2% alpha albutin (standard facial serum) or Tubtim Chumphae rice extract on either right side or left side of their face daily for 12 weeks.

Study 2: 60 male and female participants, age 30-50 years will be randomly assigned into 2 groups including 1) control group (n = 30): participants will not receive any facial mask for 12 weeks and 2) treatment group (n = 30): participants will be applied with home-based program facial mask with Hom Pathum rice extract for 30 min/day, 2 days/week for 12 weeks.

Study 3: this study consists of 2 sub-studies. Study 3.1: 25 male and female participants, age 18-35 years will be randomly consumed with control jelly, jelly with Tubtim Chumphae rice, and jelly with Hom Pathum rice at 3.5 g/kg body weight. All participants will be measured for blood glucose levels before consumption and after consumption at 30, 60, 90, and 120 min. Study 3.2: 25 male and female participants, age 18-35 years will be randomly consumed with control jelly, jelly with Tubtim Chumphae rice, and jelly with Hom Pathum rice at 3.5 g/kg body weight. After each consumption, all participants will perform walking or running on treadmill at intensity of 80% maximal heart rate to measure maximal oxygen consumption.
