Main postharvest fungi in fruits_
| Common names | Latin names | Main host crops | Main damages/symptoms | References |
|---|---|---|---|---|
| Blue mould | Citrus species, guava, mango, pome fruits, stone fruits, grapes and berries | Blue or green mould; fruit decay; softens fruits and causes rapid senescence | ( |
|
| Green mould | ||||
| Grey mould | Pome fruits, stone fruits, grapes and berries | Soft rotting; prolific grey conidiophores with collapsed and water-soaked parenchyma tissues occur | ( |
|
| Alternaria rot | Pome fruits and stone fruits | Grey, green and/or black spore colonies and spots on fruits; sunken lesions; over-ripe and softer fruits | ( |
|
| Anthracnose | Apples, avocados, bananas, mangoes and temperate fruits | Brown lesions; microbial decay | ( |
|
| Brown rot | Apricots, apples, pears, quinces, peaches, nectarines, other stone and pome fruits | Brown rot; blossom blight; cankers; fruit rots | ( |
Natural plant-based products for controlling postharvest phytopathogens_
| Main groups | Sub-groups | Important features and main advantages in postharvest handling | References |
|---|---|---|---|
| Proteins | Wheat gluten | Insoluble in neutral solvents. Has moderate elasticity and cohesiveness abilities. Provides barrier to water vapour. | ( |
| Corn zein | Insoluble in water. Has a hydrophobic nature and exhibits a good film-forming characteristic. Blocks the transport of moisture and prevents transpiration. | ( |
|
| Soy protein | Insoluble in water. Has film-forming ability for blocking moisture transfer. | ( |
|
| Lipids | Oils | Insoluble in water. Provides barrier against atmospheric gases and water vapour. Also has direct and indirect impact on fungi. | ( |
| Waxes | Most common products in postharvest handling. Has high waterproofing ability. Prevents respiration, transpiration and fungal infections. | ( |
|
| Polysaccharides | Cellulose | Has low density, high mechanical strength and film-forming characteristics. It has moderate ability for oxygen and gaseous transfer. | ( |
| Starch | Insoluble in cold water. Has low oxygen permeability but low flexibility. Delays ethylene biosynthesis and the fruit senescence. | ( |
|
| Pectin | Has a gelling characteristic with ability to maintain low moisture and controls phytopathogens. | ( |
|
| Has high film-forming ability and high antifungal characteristics. | ( |
||
| Plant gums | They have the ability to reduce the respiration rate and ethylene production, improve the resistance of products to phytopathogens and delay the fruit senescence. | ( |
|
| Secondary metabolites | Citral, eugenol, thymol etc. | They may have direct or indirect antifungal activity (by improving products’ tolerance or damaging fungi). | ( |
