Lee JS, Ahn J, Han J. Enhancing effect on postharvest quality of potatoes through combined treatment of edible coating with UV-C irradiation. Food Sci Biotechnol 2024; 33:1393-1405. [PMID: 38585569 PMCID: PMC10992078 DOI: 10.1007/s10068-023-01449-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 09/18/2023] [Accepted: 09/30/2023] [Indexed: 04/09/2024] Open
Abstract
Various edible polymers [sodium alginate, carboxyl methylcellulose, sodium oleate, liquid paraffin, pectin, pullulan, polyvinyl acetate, and shellac (SHE)] as potato-coating materials and their effect on extending the shelf life of potatoes when combined with an edible coating and UV-C irradiation treatments were evaluated. As a result of the characterization of the edible polymers, SHE was selected as the optimal coating material because it had the best moisture and light barrier properties. SHE coating successfully prevented the greening, respiration, and sprouting of potatoes caused by exposure to light and oxygen. Additionally, it reduced weight loss by inhibiting transpiration on the potato surface. While the SHE coating did not exhibit antimicrobial effects, a significant effect was observed when combined with UV-C irradiation. This study suggests the potential of combined treatment of SHE coating and UV-C irradiation in extending the postharvest quality of potatoes.

Şahansoy H, Caner C, Yüceer M. The shellac and shellac nanocomposite coatings on enhanced the storage stability of fresh eggs for sustainable packaging. Int J Biol Macromol 2024; 261:129817. [PMID: 38286370 DOI: 10.1016/j.ijbiomac.2024.129817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 01/04/2024] [Accepted: 01/26/2024] [Indexed: 01/31/2024]
Abstract
Shellac bio-coatings can enhance to improve quality and storage stability of fresh egg qualities with improved shell strength therefore minimizing the reduction the egg losses. Shellac bio-chitosan at 3 concentrations (1 %, 4 % and 8 % w/w) and shellac-1 % montmorillonite nanocomposites were applied as biocoatings to improve storage stability. Shellac-8 % (SH-8 %) coated eggs exhibited the lowest weight loss (1.28 %), significantly. The weight loss of shellac 1 % + MMT and 4 % shellac (SH-4 %) coated eggs was similar each other and had lower weight loss than 1 % shellac (SH-1 %). The Haugh Unit (HU) of eggs with SH-8 % (63.75) had the significantly the highest HU. The SH-4 % (60.24) and SH-1 %/MMT-1 % (58.04) were similar, and the control was the lowest one. The albumin pH of SH-8 % (9.15) coated exhibited a significantly lower than SH-4 % (9.21) and SH-1 %/MMT-1 % (9.24), while the control (9.39) was the highest value at end of storage. For the shellac coated group, total soluble values of albumen reached 12.87 (initial) to 16.331 (SH-1 %), 15.96 (SH-4 %), 15.60 (SH-8 %) and 16.15 (SH-%1-MMT-1 %) at the end of storage. The RWC and foam stability of SH-8 %, SH-4 % and SH-1 % MMT-1 % were similar and higher than 1 % SH and uncoated egg samples. The rheology behaviors were maintained with increasing shellac concentration through the storage. SH-8 % biocoatings were very most effective in filling and sealing the porous in the eggshell and protecting the storage stability and enhancing the strength of the eggshell. Shellac bio-coatings acted as a tiny layer for an effective protective barrier to gas permeability for enhancing the storage stability of the fresh eggs. Higher shellac concentrations (4 and 8 %) and 1 %-MMT were enhanced the storage stability and can be vital solutions for improving shell strength, so it decreases breakage rates.

Abstract
This study evaluated the microbiological and internal quality of quail eggs stored for 21 days at room temperature (29.53 ± 1.36 °C) after being coated with green banana flour and Tahiti lemon essential oil (GBF/TAH). One hundred and sixty-two quail eggs were equally distributed into three treatments: (1) uncoated eggs, (2) eggs coated with green banana flour (GBF), and (3) eggs coated with GBF/TAH. The Haugh unit (HU) of the eggs was significantly lower in the third week for uncoated eggs (70.94 ± 1.63, grade A) compared to eggs coated with GBF/TAH (81.47 ± 2.38, grade AA). On the 21st day of storage, the eggs coated with GBF/TAH had significantly lower total counts of aerobic mesophilic bacteria in the shell and egg contents compared to the other treatments. GBF/TAH coating is an effective blending approach to reduce the microbial load of the shell and egg contents and preserve the sensory and internal quality of the eggs.

Abstract
Edible films and coatings offer great potential to support sustainable food production by lowering packaging waste, extending product shelf life, and actively preserving food quality. Using edible coatings containing plant extracts with antioxidant and antibacterial characteristics could help to enhance the quality and shelf life of fish products. In this study, the combination effect of chitosan with beetroot, curcumin, and garlic extracts on biogenic amines (BAs) reduction, biochemical quality [pH, thiobarbituric acid index (TBA), trimethylamine (TMA), and total volatile base (TVB)], shelf life and sensory characteristics of tuna filets was investigated over 14 days of refrigerated storage compared to control (uncoated) samples. The results showed that the coated samples experienced a lower increase in BAs levels than the control samples. Among the treated samples, chitosan incorporated with curcumin (CH-C) showed the highest reduction in BAs formation (1.45 – 19.33, 0.81 – 4.45, and 1.04 – 8.14 mg/kg), followed by chitosan with garlic (CH-G) (1.54 – 21.74, 0.83 – 5.77, and 1.08 – 8.84 mg/kg), chitosan with beetroot extract (CH-B) (1.56 – 31.70, 0.84 – 6.79, and 1.07 – 10.82 mg/kg), and chitosan without extract addition (CH) (1.62 – 33.83, 0.71 – 7.82 and 1.12 – 12.66 mg/kg) compared to control samples (1.62 – 59.45, 0.80 – 11.96, and 1.14 – 20.34 mg/kg) for histamine, cadaverine, and putrescine, respectively. In addition, the rate of increase in pH, TBA, TMA, and TVB of all coated treatments was lower than in the control samples. Sensory evaluation results revealed that chitosan-treated samples incorporated with beetroot, garlic, and curcumin extracts showed good quality and acceptability characteristics. Overall, chitosan edible coatings incorporated with beetroot, garlic, and curcumin extracts reduced the formation of biogenic amine, delayed biochemical deterioration, and extended the shelf life of tuna filets. Among the treated samples, CH-C demonstrated a remarkable superiority in all the studied parameters. Therefore, this study provides a promising strategy for the incorporation of active compounds in edible coatings to improve the quality and safety of foods during storage.

Vrabič-Brodnjak U. Bio-Based Adhesives Formulated from Tannic Acid, Chitosan, and Shellac for Packaging Materials. Polymers (Basel) 2023; 15:polym15051302. [PMID: 36904541 PMCID: PMC10007413 DOI: 10.3390/polym15051302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 02/24/2023] [Accepted: 03/02/2023] [Indexed: 03/08/2023] Open
Abstract
The aim of this study was to develop bio-based adhesives that can be used for various packaging papers. In addition to commercial paper samples, papers produced from harmful plant species in Europe, such as Japanese Knotweed and Canadian Goldenrod, were used. In this research, methods were developed to produce bio-based adhesive solutions in combinations of tannic acid, chitosan, and shellac. The results showed that the viscosity and adhesive strength of the adhesives were best in solutions with added tannic acid and shellac. The tensile strength with adhesives of tannic acid and chitosan was 30% better than with commercial adhesives and 23% for combinations of shellac and chitosan. For paper from Japanese Knotweed and Canadian Goldenrod, the most durable adhesive was pure shellac. Because the surface morphology of the invasive plant papers was more open and had numerous pores compared to the commercial papers, the adhesives penetrated the paper structure and filled the voids. There was less adhesive on the surface and the commercial papers achieved better adhesive properties. As expected, the bio-based adhesives also showed an increase in peel strength and exhibited favorable thermal stability. In summary, these physical properties support the use of bio-based adhesives use in different packaging applications.

Food Chem 2023; 418:136030.

Abstract
This work investigated the effects of different concentrations (0.10 %, 0.15 % or 0.20 %, w/v) of gellan gum (GG) with/without 0.50 % (v/v) basil essential oil (BEO) on physicochemical properties of gellan gum-rice bran oil (GG-RBO) emulsions. The results showed that GG-RBO emulsions with 0.15 % or 0.20 % GG were more stable than GG-RBO emulsion with 0.10 % GG (as evidenced by higher apparent viscosity and absolute zeta potential, but smaller average particle size and lower turbidity), thus displaying better coating performances (as evidenced by bigger contact angle but lower moisture content). The presence of BEO further improved their stability and coating performances. Coating with GG-BRO or GG-RBO-BEO emulsion with 0.15 % GG significantly delayed the increase in weight loss, and the decrease in haugh unit, yolk index and albumen pH of eggs during 42 days storage; moreover, GG-RBO-BEO emulsion caused lower total aerobic plate count. Therefore, GG-RBO, especially GG-RBO-BEO emulsion has potential in egg preservation.
