Incorporation of carotenoids from paprika oleoresin into human chylomicrons.
    The British journal of nutrition, 2003, Volume: 89, Issue:6

    The intake of a carotenoid-rich diet is epidemiologically related to a lower risk for different chronic disorders like cardiovascular disease, some types of cancer or age-related macular degeneration. Red pepper (Capsicum annuum L.) and its dietary products contain a variety of carotenoids, which may contribute to the carotenoid pattern of human blood and tissues. The objective of the present study was to assess the availability of carotenoids from paprika oleoresin, including zeaxanthin, beta-cryptoxanthin, beta-carotene and the paprika-specific oxocarotenoids capsanthin and capsorubin. After overnight fasting, the volunteers (n 9) ingested a single dose of the paprika oleoresin containing 6.4 mg zeaxanthin, 4.2 mg beta-cryptoxanthin, 6.2 mg beta-carotene, 35.0 mg capsanthin and 2.0 mg capsorubin. At different time points the carotenoid pattern in the chylomicron fraction was analysed to evaluate carotenoid absorption. From the major carotenoids present in the paprika oleoresin only zeaxanthin, beta-cryptoxanthin and beta-carotene were detectable in considerable amounts. Although the xanthophylls in paprika oleoresin were mainly present as mono- or di-esters, only free zeaxanthin and beta-cryptoxanthin were found in human samples. The bioavailability of the pepper-specific carotenoids capsanthin and capsorubin from paprika oleoresin is very low. However, oleoresin is a suitable source for the provitamin A carotenoids beta-carotene and beta-cryptoxanthin and the macular pigment zeaxanthin.

Structure-reactivity relationship in the oxidation of carotenoid pigments of the pepper (Capsicum annuum L.).
    Journal of agricultural and food chemistry, 2001, Volume: 49, Issue:10

    The relationship between the degradation rate and structure of each pigment of the pepper carotenoid profile was studied in mixtures of dehydrated fruit with lipid substrates of differing degrees of unsaturation and in different proportions (20 and 40%). The differences in structural nature of the carotenoids present in the pepper fruit produce a variable rate of oxidation, resulting in nonuniform degradation. The yellow xanthophylls and beta-carotene have the highest rates of oxidation, with the ketocarotenoids and violaxanthin degrading at lower rates. Autoxidation is greater or lesser depending on the functional groups, which stabilize the radical intermediaries of the reaction. The behavior of capsanthin and capsorubin is that expected of carotenoids having structures that include keto groups: a markedly greater stability to autoxidation processes. This increases their antioxidant capacity, adding to their beneficial impact by reducing the proliferation of radical processes, which are detrimental to health.

Gastric cytoprotective effects of vitamin A and other carotenoids.
    International journal of tissue reactions, 1983, Volume: 5, Issue:3

    The effects of vitamin A and some carotenoids (beta-carotene, beta-cryptoxanthin, zeaxanthin, lutein, capsorubin, capsanthin, capsanthol and lycopene) were studied (a) on the development of acute gastric mucosal lesions produced by topical application of 0.6 M HCl and (b) on gastric secretion in 4-h pylorus-ligated rats. It was found (a) that vitamin A, beta-carotene, beta-cryptoxanthin, zeaxanthin and lutein significantly inhibited the development of gastric mucosal lesions produced by 0.6 M HCl, while capsorubin, capsanthin, capsanthol and lycopene failed to prevent the development of such lesions; and (b) that vitamin A, beta-carotene, beta-cryptoxanthin, zeaxanthin and lutein, i.e., the carotenoids which exerted a cytoprotective effect, had no inhibitory effect on gastric acid secretion in 4-h pylorus-ligated rats. The possible relationship between chemical structure and gastric cytoprotection is discussed.
