Development of tamarillo jam containing whole pulp

The Tamarillo (Cyphomandra betacea Sendt) is a fruit native to the Peruvian Andean region. The objective of this study was to develop the product 'tamarillo jam'. The study consisted of characterizing the fruits and their yield in pulp; presenting a protocol for the process; and carrying out a sensory analysis of three different formulations which differed according to their degree of °Brix, type of sugar and pectin content. The tamarillo fruits showed length (stem-apex), diameter and mass of 54.8 ± 4.0 mm, 34.6 ± 2.4 mm and 36.2 ± 6.5 g, respectively. The whole pulp had a sweet, slightly acid taste, with total soluble solids of 13.30 °Brix ± 0.14 and pH 4.19 ± 0.11. The fruits yielded 83.3% in whole pulp and 51.5% in mucilaginous pulp containing the seeds. Jams with 50 °Brix containing glucose or sucrose showed greater acceptance as compared to jams with 40 °Brix, containing less soluble solids. Over 70% of the panellists approved the jams with 50 °Brix for all the sensory attributes evaluated, and at least 40% expressed their intention to purchase it. Thus, considering the lower cost of sucrose as compared to glucose, the protocol for the production of tamarillo jam at 50 °Brix using sucrose and 2% of pectin was recommended.
