‘Tahong’ used in the development of cosmetics


CALOOCAN CITY, (PIA) — In addition to using mussel as food, a project recently used food-grade mussel glycogen extracts in the development of cosmetics.

According to the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development of the Department of Science and Technology (DOST-PCAARRD), green mussel (Perna viridis) is one of the emerging aquatic products that is about to contribute to economic production. of the fishing sector in the country.

The project “Mussel Glycogen Extraction and Utilization in the Mussel Biotechnology Program” was implemented by the University of the Visayas of the Philippines – Tacloban Campus, in collaboration with DOST-PCAARRD.

Two other mussels, the black mussel (Mytella strigata) and the brown mussel (Modiolus philippinarum) were included in the study.

Cosmetic products (cream, ointment and soap) from food grade glycogen extracts and laboratory grade glycogen for biotechnology purposes have been formulated. Laboratory-grade glycogen has been shown to be effective as a carrier in nucleic acid extraction when used in standard PCR techniques.

To support the project in terms of commercialization, a feasibility study on the commercialization operations (production, organization, management) of the developed glycogen concluded that it is feasible to manufacture this product.

The results of the financial analysis are very encouraging with an Internal Rate of Return (IRR) of 193.95% and a Benefit-Cost Ratio (BCR) of 1.70. IRR is the expected growth rate of an investment per year (average: 22%) while BCR is the correlation of relative costs to benefits of a proposed project in which a value greater than 1.0 will mean a positive net present value.

Research into non-food applications of mussels has been encouraged as mussel production faces the ongoing occurrence of harmful algal blooms (HABs). HABs displace fishermen for months and incur economic losses of up to 250 million Pula (M) per HAB occurrence.

In the province of Samar alone, in Region VIII, the P49M comes each year from the “tahong” industry. DOST/PIA-RCN)
