| Summary, etc. |
Typically, seaweed farmers use sun drying in an open area exposed to direct<br/>sunlight. This method in drying of seaweeds requires large open area and long drying<br/>time which may result to low product quality. It is necessary if the period of drying could<br/>be decreased without affecting quality of the seaweed. This research aimed to investigate<br/>the application of hot water blanching pre-treatments to enhance drying of seaweeds<br/>(kappaphycus alvarezii S.), moreover, to analyze the drying characteristics, proximate analysis and sensory characteristics of seaweed as affected by hot water blanching pre-<br/>treatments and dried using solar glass dryer and heated air mechanical dryer. Simple cost analysis was also performed to assess the annual cost and custom rate of using solar glass<br/>dryer and heated air mechanical dryer.<br/>Results revealed that in heated air mechanical dryer, samples blanched for 5 and<br/>15 seconds dry faster (8 hours). In solar glass dryer, seaweed samples blanched at 5<br/>seconds dry earlier (32.67 hours). Results imply that hot water blanching affects drying<br/>time in drying seaweeds and hot water blanching pre-treatments increased drying rate at<br/>the initial hour of drying. All drying curves were subjected to regression analysis and<br/>from the results obtained, it could be verified that the models fitted shows good predicting capacity and reveals good correlation coefficient between the fitted model and<br/>experimental data.<br/>Hot water blanching pre-treatments and types of dryers did not significantly affect<br/>the total ash contents of the seaweed powder, while in crude protein levels, results<br/>revealed that hot water blanching pre-treatment were not significant within the dryers but significantly different in terms of method of drying. Moreover, hot water blanching pre-<br/>treatments within the dryer were significantly different in crude fiber levels but insignificant in comparison between dryers, except for samples blanched at 30 seconds<br/>that were significant.<br/>Results imply that color of the seaweed powder dried in solar glass dryer was<br/>preferred by panels. It was observed that all seaweed samples dried using heated air mechanical dryer turned to dark color. Results revealed that hot water blanching pre-<br/>treatments and types of dryer do not affect the texture and odor preference of the panels.<br/><br/>As rated by panels, general acceptability scores of the seaweed powder were<br/>insignificantly different within dryers.<br/>Data showed that when using solar glass dryer, it is profitable to blanch the<br/>seaweeds before drying with custom rate of Php 67.23 per kg., payback period 0.54 year,<br/>and annual net income of Php 12,951.21, while when using heated air mechanical dryer,<br/>it is cost-effective to blanch the seaweeds before drying with custom rate of Php 162.32,<br/>payback period 0.27 year, and annual net income of Php 551,204.81. |
