The Philippine Agricultural Scientist

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.

Agriculture And Community Well-Being: A Review Of Three Research Studies., Marilyn R. Schlake

Cornhusker Economics

Personal observations are often obscure to the facts. For instance, recently I worked at a booth at Husker Harvest Days. The booth focused on rural community development. My observations were that many of the agricultural producers decided to not stop at our booth or for those who did stop, conversations showed a disconnect of the importance of their local community to their farm operations. Similarly, when working with communities, I have observed the lack of understanding of the importance of the agricultural producers to the local community’s well-being. Why the disconnect between these two very important components of our rural …
