Climacteric ripening |
A small volatile molecule causes fruit ripening (Ethylene) |
|
|
Non-climacteric ripening |
• Happens gradually over time and doesn’t depend upon ethylene • Once harvested these do not continue to ripen or improve • Get softer but not sweeter |
|
|
Berries |
Entire pericarp is fleshy, may be one or many seeds |
|
|
Hesperidium |
Berries with a leathery rind (exocarp, mesocarp and endocarp) and parchment-like partitions between sections (endocarp) |
|
|
Pepo |
Berry with a hard, thick rind (exocarp) and fleshy mesocarp |
|
|
Drupes |
A one-seeded fruit having a hard endocarp (stone or pit), a fleshy mesocarp, and a thin exocarp that is flexible or dry |
|
|
Legumes |
A dry fruit • Pericarp that splits open along a seam |

|
Texture factors |
-Turgor -Structure of cell wall |
|
|
Crisp tenderness |
comes from how much water is in the plant cells |
|
|
Mealiness |
Mealy, grainy, dry texture • Results when the cement between neighboring cells is weak, so that chewing breaks the cells apart from each other rather than breaking them open, and we end up with lots of tiny separate cells in our mouth |
|
|
Meltingness |
Due to the activity of enzymes breaking down the cell walls • weakening is so extreme that the cell walls practically disintegrated, and the watery cell interior oozes out under the least pressure |
