Abstract

A study to substitute sweet potato flour for wheat flour dough has been conducted using two type of wheat flour and various percentage of substitution. To test the degree of substitution, the characteristics of dough were measured using Brabender farinograph and Brabender Extensograph. Measurement of rheological properties using farinograph showed that the dough made of 60% sweet potato flour with hard wheat and those of 40% sweet potato flour with medium wheat cannot be done. Viscoelasticity of dough from 40% or more sweet potato flour with hard or medium wheat cannot be measured using Extensograph.

Abstract

A study on canning of shrimp has been conducted in order to decide the best processing stages. The effect of acid soaking of shrimp on the products has also been studied. Observation was done on pH, microbiology and acceptabitity test using 34 panelist. The result showed that 20 minutes of sterilization resulted in a sterile canned shrimp (total bacteria: 0-5 x 10^1 colony per g; coliform: 0 and anaerobic thermophilic bacteria: negative). The colour, taste and aroma of the product was acceptable, while the texture was not due to its softness.

Abstract

A study to substitute sweet potato flour for wheat flour in cake making had been carried out. The acceptability of substitution was analyzed by panel test using cake made from teo kinds of wheat flou and various percentages of substitution (0,2040 and 60%). The product were also analyzed chamically and organoleptically. The result showed that the use of sweet potato flour significantly affect water, protein and sugar content of the cake. Twenty percent of sweet potato flour substitution showed significant different with those of 40 and 60%. Organoleptic test showed that the 20% substitution is acceptable
