Imagine a peanut or a nut like a tiny, super dry sponge. When it's dry, it's really hard and crunchy because it doesn't have much water inside, and all its little parts are packed together very tightly. Think of it like a tiny, firm package. When you put that nut

Materials Science Engineer (Food)

The inherent hardness of peanuts and nuts in their dry state is attributed to a highly compact, dehydrated microstructure, comprising rigid cell walls and a dense matrix of macromolecules, primarily proteins andaccharides. Upon immersion in water, the material undergoes significant water absorption, with water molecules penetrating the cellular and intercellular spaces. This absorbed water acts as a plasticizer within the food matrix. It interacts with hydrophilic components such as cellulose and hemicellulose in the cell walls, as well as the protein bodies and any starch granules present. These interactions disrupt existing intermolecular hydrogen bonds, thereby increasing the molecular mobility and flexibility of these structural polymers. Consequently, the cellular components swell, and the overall rigidity of the tissue is significantly reduced. This leads to a decrease in the material's fracture strength and an increase in its deformability, which is macroscopically perceived as softening. The structural integrity is compromised by the hydration and plastic

The softening of nuts and peanuts when soaked in water is a direct consequence of cellular rehydration and the alteration of their material properties. In their dry state, these foods possess a rigid, brittle structure due to dehydrated cellular components and minimal internal moisture. When submerged, the nuts absorb water through osmosis and capillary action, drawing it into their cellular matrix. This absorbed water interacts with the primary structural elements: the plant cell walls, composed largely of cellulose and hemicellulose, and internal

Plant Cell Biologist

Nuts and peanuts, as mature seeds, are characterized by highly dehydrated cells. Their inherent hardness and structural integrity are primarily conferred by robust, often lignified or heavily cross-linked polysaccharide cell walls, composed

Food Scientist

The softening observed in peanuts and nuts when soaked in water is primarily a result of the rehydration and swelling of their cellular and structural components. These foods possess a dense matrix of carbohydrates, proteins, and lipids encased within rigid cell walls. Water molecules penetrate the seed coat and cell membranes, leading to absorption by hydrophilic polymers within the cells. Specifically, the complex carbohydrates within the cell walls, such as cellulose, hemic

Points of agreement

• The softening is primarily due to the absorption of water (rehydration) into the food's structure.
• The inherent hardness of dry nuts is attributed to their dehydrated
