Hydroxypropyl Methylcellulose-Based Edible Coatings Formulated with Antifungal Food Additives to Reduce Alternaria Black Spot and Maintain Postharvest Quality of Cold-Stored ‘Rojo Brillante’ Persimmons
Composite edible coatings based on hydroxypropyl methylcellulose (HPMC), as a polymeric phase, and oleic acid (OA) or beeswax (BW), as a hydrophobic phase, were formulated with different food additives as antifungal ingredients. HPMC–OA coatings containing 2% (w/v) sodium benzoate (SB), 1% ammoni...

| description | Composite edible coatings based on hydroxypropyl methylcellulose (HPMC), as a polymeric
phase, and oleic acid (OA) or beeswax (BW), as a hydrophobic phase, were formulated with
different food additives as antifungal ingredients. HPMC–OA coatings containing 2% (w/v) sodium
benzoate (SB), 1% ammonium carbonate (AC), 1% potassium carbonate (PC), 1% potassium bicarbonate
(PBC), 1% sodium bicarbonate (SBC), 1% potassium silicate (PSi), 0.1% sodium methyl
paraben (SMP) or 0.1% sodium ethyl paraben (SEP), and HPMC–BW coatings containing 2% sodium
propionate (SP), 2% PBC, 2% SB or 0.1% SEP were evaluated for the control of Alternaria black spot
(ABS) on Diospyros kaki Thunb. ’Rojo Brillante’ persimmons artificially inoculated with Alternaria
alternata. After 14 days of incubation at 20 ºC, HPMC–OA coatings formulated with PBC, PC or SEP
were the most effective to reduce ABS incidence (61, 54, and 36% reduction, respectively, concerning
uncoated control fruit) and severity (28, 12 and 22% reduction, respectively), while only HPMC–BW
coatings formulated with SEP significantly reduced ABS incidence (50% reduction) and severity (36%
reduction). HPMC–OA and HPMC–BW coatings containing 2% PBC or 0.1% SEP were selected to
evaluate their effect on the weight loss, firmness and respiration rate of healthy ‘Rojo Brillante’ persimmons
cold-stored at 1 ºC and 90% relative humidity (RH) for 15 and 30 days, followed by 7 days
of shelf life at 20 ºC. HPMC–BW coatings were more effective in reducing fruit weight and firmness
losses than HPMC–OA coatings, while all antifungal coatings significantly reduced fruit respiration.
Overall, the HPMC–BW edible coating that contains SEP could be a promising postharvest treatment
to control ABS and maintain the quality of cold-stored ‘Rojo Brillante’ persimmons. |
