2010 article

An Update on the Health Effects of Tomato Lycopene

ANNUAL REVIEW OF FOOD SCIENCE AND TECHNOLOGY, VOL 1, Vol. 1, pp. 189–210.

By: E. Story n, R. Kopec *, S. Schwartz* & G. Harris  n

author keywords: lycopene; carotenoids; lycopenoids; bioavailability; cancer; cardiovascular disease
MeSH headings : Animals; Anticarcinogenic Agents / administration & dosage; Anticarcinogenic Agents / analysis; Anticarcinogenic Agents / chemistry; Anticarcinogenic Agents / metabolism; Antioxidants / administration & dosage; Antioxidants / analysis; Antioxidants / chemistry; Antioxidants / metabolism; Cardiovascular Diseases / prevention & control; Carotenoids / administration & dosage; Carotenoids / analysis; Carotenoids / chemistry; Carotenoids / metabolism; Food Handling; Fruit / chemistry; Health Promotion; Humans; Lycopene; Solanum lycopersicum / chemistry
topics (OpenAlex): Antioxidant Activity and Oxidative Stress; Retinoids in leukemia and cellular processes; Cholesterol and Lipid Metabolism
TL;DR: Although promising data from epidemiological, as well as cell culture and animal, studies suggest that lycopenes and the consumption of lycopene containing foods may affect cancer or cardiovascular disease risk, more clinical trial data is needed to support this hypothesis.

2001 journal article

Sweet potato buds: the origins of a "designer" food to combat hypovitaminosis A in Guatemala. Processing, vitamin A content and preservation characteristics

NUTRITION RESEARCH, 21(1-2), 61–70.

By: C. Valdez, C. Lopez, S. Schwartz n, J. Bulux & N. Solomons

author keywords: sweet potato (SPB); beta-carotene; retinol equivalents
topics (OpenAlex): Antioxidant Activity and Oxidative Stress; Food Chemistry and Fat Analysis
TL;DR: A Guatemalan version of sweet potato flakes, called “sweet potato buds” (SPB), was created from Ipomoea batata by the drum-drying technique used to create instant mash potatoes, and the β-carotene levels fell steeply, to the point of extinction within 4 months, independent of the type of barrier or the addition of food-grade antioxidants.

2000 journal article

Effects of ozone and oxygen on the degradation of carotenoids in an aqueous model system

JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 48(10), 5008–5013.

By: L. Henry n, N. Puspitasari-Nienaber n, M. Jaren-Galan n, R. Breemen  n, G. Catignani n & S. Schwartz n

author keywords: ozone; oxidation; carotenoids; beta-carotene; beta-cryptoxanthin; lycopene; degradation
MeSH headings : Carotenoids / chemistry; Chromatography, High Pressure Liquid; Kinetics; Mass Spectrometry; Models, Chemical; Oxygen / chemistry; Ozone / chemistry
topics (OpenAlex): Antioxidant Activity and Oxidative Stress; Free Radicals and Antioxidants; Phytochemicals and Antioxidant Activities
TL;DR: The effects of ozone and oxygen on the degradation of carotenoids in an aqueous model system were studied and the major degradation products of beta-carotene were tentatively identified on the basis of their elution on the HPLC column, UV-Vis spectra, and electrospray LC-MS.

1999 journal article

Carotenoid composition of marigold (Tagetes erecta) flower extract used as nutritional supplement

JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 47(10), 4189–4194.

By: W. Hadden n, R. Watkins n, L. Levy n, E. Regalado n, D. Rivadeneira n, R. Breemen  n, S. Schwartz n

author keywords: lutein; marigold (Tagetes erecta); poultry; feed colorant
MeSH headings : Animal Feed; Animals; Carotenoids / analysis; Chromatography, High Pressure Liquid; Dietary Supplements; Food Coloring Agents; Humans; Nutritive Value; Plant Extracts / chemistry; Poultry
topics (OpenAlex): Antioxidant Activity and Oxidative Stress; Plant biochemistry and biosynthesis; Phytochemicals and Antioxidant Activities
TL;DR: This compositional determination is important for the application of marigold extract in nutritional supplements and increases its value as a poultry feed colorant because it contains more biologically useful lutein compounds than previously believed. (via Semantic Scholar)
