Pangi (Pangium edule Reinw) seed is known to be a poisonous material. However, it becomes safe for consumption after processing. This study determined the effect of village-level processing by the Obu Manuvu community of Marilog District, Davao City, Philippines on the antinutrient and nutritional composition of Pangi seeds. Processing methods involved washing with running water for about 15 s, boiling in water for 30 min, and soaking in flowing water in a nearby river overnight. Results showed that after processing, the levels of antinutrients such as cyanogenic glycosides and oxalates were reduced significantly (p < 0.05) by 99.15% and 78.23%, respectively. Further, the tannin content was also significantly reduced by 96.15%. The crude fat content significantly increased (p < 0.05) by about 54%. Crude ash and fiber decreased, while protein did not change significantly (p < 0.05). Minerals such as calcium and zinc increased (p < 0.05) by 221.43% and 64.39%, respectively while the iron and manganese levels remained unaffected. Findings of the study suggested that the processing method by the Obu Manuvu effectively reduces the level of antinutrients, thereby improving the edibility and safety of Pangi seeds. Further, the processing method improves the level of some nutrients, specifically crude fat, calcium, and zinc.


Exploring The Nutritional, Antioxidant, And Lipid-Lowering Properties Of Saba Banana (Musa Acuminata X Balbisiana Bbb Group) Peels, Paul Alteo Bagabaldo, Liezl M. Atienza, Katherine Ann T. Castillo-Israel, Aimee Sheree A. Barrion, Antonio C. Laurena, Maria Amelita C. Estacio Dec 2023

This study investigated the nutritional and functional components of ‘saba’ banana peel (SBP) to determine its health-promoting potential for special food applications. SBP has undergone analyses measuring proximate composition, vitamin C, antioxidant activity, phytochemical content, estimated glycemic index (eGI), pancreatic lipase inhibition, and cholesterol micellar solubility inhibition. Data were processed using SPSS v20 and expressed as mean ± SD. Proximate analysis showed that SBP contained 83.83 ± 1.06% moisture, 6.74 ± 0.83% crude fat, 5.58 ± 0.24% crude protein, 9.97 ± 0.04% total ash, 9.91 ± 0.10% crude fiber, and 60.08% nitrogen-free extracts. Vitamin C content was found to be …


Angiotensin I-Converting Enzyme Inhibitory And Antioxidative Activities Of The Bioactive Peptides In The Crude Salt-Soluble Protein Hydrolysates Of Pili Nut (Canarium Ovatum Engl.) Cv. Mayon Kernel, Ella Mae Gamba, Lawrence Yves Uy, Mary Ann Torio Jun 2023

Angiotensin I-Converting Enzyme Inhibitory And Antioxidative Activities Of The Bioactive Peptides In The Crude Salt-Soluble Protein Hydrolysates Of Pili Nut (Canarium Ovatum Engl.) Cv. Mayon Kernel, Ella Mae Gamba, Lawrence Yves Uy, Mary Ann Torio

The Philippine Agricultural Scientist

The in silico enzyme digestion and peptide function annotation of pili nut (Canarium ovatum Engl.) 11S globulin protein sequence revealed the presence of bioactive peptides with antihypertensive and antioxidative activities. Molecular docking simulations showed that the proline-histidine (PH) ligand can better inhibit angiotensin I-converting enzyme (ACE) activity than captopril. This result was verified through biochemical assays. Pili kernel protein was extracted with 0.5 M NaCl buffer using the modified Osborne fractionation method, which yielded 100 mg of protein per gram of defatted pili kernel determined via Bradford assay. SDS-PAGE suggested that the protein extract had a major legumin-like (11S) …


Evaluation Of The Inactivation Kinetics Of Cronobacter Sakazakii In Infant Formula Treated By Radio Frequency Dielectric Heating And Uvc Light [Research Note], Yun Deng, Yuwei Wu, Yuanrong Zheng, Danfeng Wang, Zhenmin Liu Mar 2021

Evaluation Of The Inactivation Kinetics Of Cronobacter Sakazakii In Infant Formula Treated By Radio Frequency Dielectric Heating And Uvc Light [Research Note], Yun Deng, Yuwei Wu, Yuanrong Zheng, Danfeng Wang, Zhenmin Liu

The Philippine Agricultural Scientist

We studied the inactivation kinetics of Cronobacter sakazakii (CS) in infant formula subjected to radio frequency dielectric heating (RF) alone or sequential RF-UVC irradiation for 30 min. We used one linear model and two nonlinear models to fit the data and compared the results. Our findings revealed that CS was more susceptible to the combined treatment than to RF alone at the same temperature and that inactivation rate increased with increasing temperature. The sequential RF (90°C, 5 min) - UVC (25 min) treatment was the most effective at inactivating CS. The survival curves of CS were non-linear. …


16s Rrna Gene Sequence Analysis Of Acetic And Lactic Acid Bacteria Isolated From Philippine Sugarcane Wine (Basi) [Research Note], John Russel G. Sevilla, Michael Angelo S. Esteban, Honey Bhabes R. Iñigo, Audrey May V. Orillaza, Baby Richard R. Navarro Mar 2021

16s Rrna Gene Sequence Analysis Of Acetic And Lactic Acid Bacteria Isolated From Philippine Sugarcane Wine (Basi) [Research Note], John Russel G. Sevilla, Michael Angelo S. Esteban, Honey Bhabes R. Iñigo, Audrey May V. Orillaza, Baby Richard R. Navarro

The Philippine Agricultural Scientist

Basi, a traditional sugarcane wine of the Philippines, was studied. Here, we used molecular- and cultural-based methods to isolate, identify and characterize acid-producing bacteria, specifically acetic and lactic acid bacteria, from basi. Acid producers were focused on owing to the rapid spoilage of basi via acidification with air exposure. Two strains each of acetic and lactic acid bacteria were isolated. DNA was extracted from these isolates. PCR-amplified DNA products were subjected to 16S rRNA gene sequencing. The sequences of the isolates were then aligned with BLAST database sequences and found to have high similarities to Acetobacter malorum (99%), …
