PhilRice researches acknowledged in crop science conference

Studies on stress-tolerant rice, healthy rices, mechanized inbred rice seed production, novelty rice products, and high-technologies by the Philippine Rice Research Institute (PhilRice) were recently recognized in a scientific gathering led by the Crop Science Society of the Philippines (CSSP).

In the 48th CSSP Scientific Conference, 14 PhilRice studies were awarded in different categories owing to their importance in advancing agricultural sustainability and development in the countryside.

To be specific, the study Morphological and Dry Matter Yield of Rice Genotypes in Response to Drought Stress and Rewatering at Vegetative Stage by Gem Faustino, Jose Hernandez, Nenita Desamero, and Rolando Cruz won first place in the Crop Physiology and Biochemistry category.

Through the experiment, 8 out of 17 rice genotypes were spotted to have the ability to withstand drought stress during vegetative stage. Plant irrigation was withheld for 20 days and were rewatered for 10 days with 2-3 cm floodwater depth.

“The slow progression of drought stress indicators such as leaf rolling and leaf tip drying were identified to have helped the plant maintain its water status and photosynthetic ability, thereby withstanding the possible effect brought about by lack of irrigation,” said Faustino, research team member.

For the Postharvest Handling, Processing, and Utilization category, Rodel Bulatao, John Paulo Samin, and Paul Jhon Eugenio also garnered first place for their study Encapsulation of Black Rice Bran Anthocyanin-Rich Extract: Optimization and Characterization.

Anthocyanins are known for their benefits specifically in cardiovascular health, and anti-cancer and anti-inflammatory properties. The team have identified encapsulation as an effective method to optimize the use of anthocyanins in black rice bran.

“The capsules developed in the study had high phenolic content and strong antioxidant activity; making it a promising material for food and pharmaceutical use,” Bulatao said.

Meanwhile, Josefina Ballesteros, El Shaira Labargan, Rosaly Manaois, Amelia Morales, and Riza Ramos won first place for their study Research to Revenue: The Feasibility of Brown Rice Cracker Ice Cream Sandwich (BRICS) in the Technology Extension, Dissemination, Education, and Socioeconomics category.

BRICS contains brown rice and buffalo’s milk. It is a nutritious and energy-dense snack food for 15 to 30 years old and has high market potential. Results also show that commercializing the product for five years will generate positive net profits and net cash flows with a payback period of 2.4 years.

On the other hand, the Low Protein Rice for Chronic Kidney Disease Patients and Individuals Requiring Reduced Protein Diet study by Marissa Romero, Princess Belgica, Maricar Castillo, Henry Mamucod, Manuel Jose Regalado, and Amelia Morales won first place in the Technology Development category.

Optimization of the process with collaborator Biotech Japan Corporation resulted in appropriate rice protein reduction. It was also found that certain local varieties such as NSIC Rc 304, NSIC Rc 242, NSIC Rc 160, NSIC Rc 222, and NSIC Rc 152 can be used in developing low-protein rice with acceptable quality for consumption.

“In our country where rice is the staple food, reducing its protein content would be an excellent strategy to help patients with chronic kidney disease who require low protein and other individuals with restricted protein diet,” Romero explained.
