Differential Scanning Calorimetry (DSC)
A technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. This is relevant to seed storage in that lipid composition within a seed can be measured using this technique without harming the seed.
Responses of Papaya Seeds (Carica papaya) During Short and Long Term Storage at Sub-zero Conditions
Christina Walters, Jennifer Crane, Lisa Hill, United States Department of Agriculture., USDA-ARS Seeds of papaya (Carica papaya) are tolerant to desiccation, but they are quickly damaged when stored at -5 to -20C. The seeds have a high lipid content that reflect “tropical oils,” which are high in saturated and mono-unsaturated fatty acids. Differential Scanning Calorimetry […]
