Effect of Hydroxypropyl Methylcellulose-Beeswax Composite Edible Coatings Formulated with or without Antifungal Agents on Physicochemical Properties of Plums during Cold Storage

Table 2

Titratable acidity (TA), soluble solid content (SSC), and maturity index (MI) of “Friar” plums uncoated or coated with hydroxypropyl methylcellulose-beeswax edible coatings containing potassium sorbate (PS), sodium methyl paraben (SMP), or sodium ethyl paraben (SEP) and stored for 22 d at 1°C followed by 5 d at 20°C.

Values at harvest: TA = 1.83 ± 0.09 g malic acid/100 mL; SSC = 13.67 ± 0.19 g sucrose/100 mL; MI = 7.5 ± 0.29; A: uncoated; Control B: coating without antifungal agent. Mean values with different letters within the same column are significantly different according to Duncan’s multiple range test () (mean ± SE; ).
