Based on the Source, the corn feed segment has considerable growth during the forecast period, as it is a rich source of protein and xanthophyll. Corn gluten feed (CGF) is a co-product obtained from wet-corn milling industry which is engaged in manufacturing of starch, sweeteners, syrup, and oil from corn.
This finding may be a result of the decreased proportion of corn, which contains carotenoid-type pigments such as chlorophyll or xanthophyll [28].
However, commercial feed later significantly developed the higher yellowness due to the presence of xanthophyll. Research showed that the use of vitamin E and oil as a supplement in a chicken Feed affect the oxidation of protein and fat of meat during preservation.
Lutein is a type of carotenoid called a xanthophyll, known for its antiinflammatory properties.
Carotenoids and NPQ are responsible for energy dissipation during the xanthophyll cycle and, consequently, prevent damage to the photosynthetic apparatus during stress (Demmig-Adams & Adams, 1996).
Since ethoxyquin, as a preservative, is highly efficient in slowing down the oxidation of carotene, xanthophyll, and vitamin A and vitamin E in pet food products, to ensure long shelf-life, its demand is rising substantially with the augmenting need for pet food products, reflecting greatly on the overall market.
Moreover, astaxanthin, a xanthophyll carotenoid, is a nutrient with a unique molecule structure; it does not convert to vitamin A (retinol) and has no 'pro-oxidant' activity."
(2015), the dissipation of excess energy is a mechanism of release and regulation of PSII, allowing the closure of the reaction centers and preserving the cycles of xanthophyll and lutein.
(2) This indicated a favorable cognitive impact of the xanthophyll supplement.
Methanol extracts were obtained for each plant (Dominguez, 1973) to quantify and determine types of sugars following Somogyi-Nelson (Gonzalez & Penalosa, 2000), total structural sugars (Wood's technique, 1952) (Din et al., 2009), xanthophyll (official method 970.64), and carotenoids (official method 938.04) (AOAC, 2006) using HPLC.
In addition to an intense content of fatty acids that protect cardiac health, the Urfa pistachio nut has also been determined to contain many phytochemical substances such as protein, diet fibers, potassium, magnesium, vitamin K, and [gamma]-tochopherol and has been determined to have the highest potassium, [gamma]-tochopherol, vitamin K, phytosterols, and xanthophyll carotenoid content of all the Pistacia species (1).
