Applications

Beta Carotene is an organic compound and classified as a terpenoid. It is a precursor (inactive form) of vitamin A.Target: OthersBeta Carotene is a strongly colored red-orange pigment abundant in plants and fruits.β-Carotene is biosynthesized from geranylgeranyl pyrophosphate. It is a member of the carotenes, which are tetraterpenes, synthesized biochemically from eight isoprene units and thus having 40 carbons. Among this general class of carotenes, β-carotene is distinguished by having beta-rings at both ends of the molecule. Absorption of β-carotene is enhanced if eaten with fats, as carotenes are fat soluble [1, 2].

Abstract

β-Carotene is one of the most abundant natural pigments in foods; however, usage of β-carotene is limited because of its instability. Microencapsulation techniques are usually applied to protect microencapsulated β-carotene from oxidization. In this study, β-carotene was microencapsulated using different drying processes: spray-drying, spray freeze-drying, coating, and spray granulation. The properties of morphology, particle size, water content, thermal characteristic, and chemical stability have been explored and compared. Scanning electron microscopy measurements showed that the coated powder had a dense surface surrounded by starch and suggested that the coating process gave a microencapsulated powder with the smallest bulk density and the best compressibility among the prepared powders. The chemical stabilities of microcapsules were evaluated during six months of storage at different temperatures. The coated powder had the highest mass fraction of β-carotene, which indicated that the coating process was superior to the three other drying processes.

Abstract

Data from 18 β-carotene-deficient Japanese Black cows were collected to clarify the effects of feeding β-carotene-enriched dry carrots on β-carotene status and colostral immunoglobulin (Ig) in cows. Cows were assigned to control or carrot groups from 3 weeks before the expected calving date to parturition, and supplemental β-carotene from dry carrots was 138 mg/day in the carrot group. Plasma β-carotene concentrations in the control and carrot groups at parturition were 95 and 120 μg/dL, and feeding dry carrots slightly improved plasma β-carotene at parturition. Feeding dry carrots increased colostral IgA concentrations in cows and tended to increase colostral IgG1 , but colostral IgM, IgG2 , β-carotene and vitamin A were not affected by the treatment. Feeding dry carrots had no effects on plasma IgG1 , IgA and IgM concentrations in cows, but plasma IgG1 concentrations decreased rapidly from 3 weeks before the expected calving date to parturition. These results indicate that feeding β-carotene-enriched dry carrots is effective to enhance colostral IgA and IgG1 concentrations in β-carotene-deficient cows.

Abstract

Understanding the bioactive partitioning between the phases of an emulsion system underpins strategies for improving the efficiency of bioactive protection against degradation. We analysed partitioning of β-carotene in emulsions with various formulations in-situ using confocal Raman microscopy (CRM). The partitioning of β-carotene into the aqueous phase of emulsions increased when whey protein isolate (WPI) was heat or high pressure-treated prior to emulsion formation. However, increasing the concentration of high pressure-treated WPI reduced the β-carotene partitioning into the aqueous phase. Increasing the solid fat content in the carrier oil favoured the migration of β-carotene into the aqueous phase. The use of WPI as the emulsifier resulted in a greater partitioning of β-carotene into the aqueous phase compared to when Tween 40 was the emulsifier. This study demonstrates that partitioning of β-carotene between the aqueous and oil phase is dependent on the characteristics of the oil phase, emulsifier type and processing.
