Technical Report ·
OSTI ID:4249015
Four vegetables irradiated at 1.86 megarads were packed under 21 different conditions and analyzed at five periods up to one year of storage. Data are presented on the chlorophyll, pheophytin, carotene, and xanthophyll content for green beans and broccoli, and the total carotenoids, xanthophyll, beta-carotene and alphacarotene for sweet potatoes and carrots. The reflectance, hue and chroma for each product as well as the pigment-free residues are also presented. Some studies on apple products, pectin gels, organic acid-sugar systems and hydroxymethylfurfural are included. (auth)
