Brief Description

Collection of Sargassum samples will be done at the coastal town of Ilocos Norte particularly in Paayas, Burgos, Ilocos Norte. Experiments will be done at MMSU-CASAT Fish Processing Laboratory.

Data collection will be done by experimental research method. This will include the determination of heavy metals present on Sargassum seaweed and proximate analysis will be undertaken. The formulated food products from Sargassum will be subjected to sensory evaluation by 10 trained panellists of MMSU-CIT, Food Tech. Dept.

Seaweed, Sargassum will be collected monthly from the collection site. The seaweeds will be washed with sea water and placed in a plastic container. The seaweeds will be brought to the Laboratory and will be washed with fresh water, remove the adhering epiphytes and foreign materials and will be cut into desired sizes. The seaweeds will be soaked in 0.1 M HCl at 1:50 (w/v) ratio. Afterwhich, the seaweeds will be washed with distilled water and dried at 50 °C overnight (DAVIS et al. 2000).

The seaweeds will be brought to FNRI for the determination of the presence of heavy metals such as Cd, Co, Cu, Fe, Ni, Pb, and Zn.

Formulation and standardization of food products will be done to improve the acceptability of the food products to consumers. Food products to be develoed are the following:

Food Product 1. Sargassum Pickle

Food Product 2. Iodine-Enriched Kroepeck

Food Product 3. Iodine-Enriched Polvoron

Food Product 4. Sargassum Tea

Acceptability test of the developed food products:

  • Sensory evaluation
  • Data analysis
  • Shelf-life analysis of the food products
  • Proximate and nutrition analysis of the seaweed food products
 
Expected Output

Accomplishments and major findings:

Acceptability was tested by presenting the products to panel of 30 evaluators randomly selected from MMSU-CASAT composed of 10 faculty, 10 staff and 10 students for assessment of its general acceptability using a 9-point Hedonic rating scale.

Results of the evaluation showed that the products are generally acceptable. Scores obtained for general acceptability were in the 7 to 8 point range in the hedonic rating scale or "like moderately" to "like very much".

Scores obtained for general acceptability of the Seaweed Pickle were in the 7 to 8 point range in the hedonic rating scale or "like moderately" to "like very much"; the Seaweed Kroepeck obtained a score of 8 to 9 point range or "like very much" to "like" to "like extremely"; Iodine-enriched Polvoron with a rating of 7 to 8 and Sargassum Tea with 6 to 7 respectively.
