Study on texture properties changes of Guanxi honey pomelo juice sacs during storage

Changes of texture properties of Guanxi honey pomelo juice sacs were studied by using texture profile analysis.Granulation index of Guanxi honey pomelo increased during both 5 and 25℃ storage, meanwhile there was also an obvious increase in firmness, springiness, cohesiveness, gumminess and chewiness.The correlation coefficients analysis indicated that Adhesiveness did not show any correlation with other texture parameters, while significant positive correlation ( R = 0.723 ~ 0.983) were observed among firmness, springiness, cohesiveness, gumminess, chewiness.Granulation index of Guanxi honey pomelo had positive correlation with all texure parameters, except adhesiveness ( R = 0.793 ~ 0.988) .Therefore, firmness, springiness, cohesiveness, gumminess and chewiness can be used to evaluate texture changes of pulp junice sacs and identify the granulation level of Guanxi honey pomelo juice sacs during storage.
