Abstract:
This study was carried out to evaluate the quality of packed frozen custard apple pulp when it kept at ambient condition. The pulp was extracted from custard apple with the help of Dr. PDKV deseeding machine. For experiment the pulp was packed in LDPE bags and preserved with four different treatments viz Blast freezing + Potassium metabisulphite (KMS 0.1 %), Blast freezing + Control, Without Blast freezing + Potassium metabisulphite (KMS 0.1 %) and Without Blast freezing + Control stored at frozen storage (-18 °C). The frozen pulp was kept at ambient condition and monitored TSS, acidity, pH, ascorbic acid and L Value continuously at an interval of 1 hr for 8 hr. The results revealed that the pH and L- value, ascorbic acid were decreased while total soluble solids and acidity were increased with increased storage time up to 8 hr at ambient condition. The pulp treated with blast freezing along with KMS (0.1%) (T₁) and without blast freezing along with KMS (0.1%) (T₃) were found in good condition up to 8 hr however, the pulp treated with blast freezing and without KMS (T₂) and without blast freezing and without KMS (T₄) were spoiled after 4 hr.
