Production of high-quality healthy foods through sustainable methodologies is an urgent necessity. High pressure homogenization (HPH) is an interesting alternative to obtain premium citrus juices, but its effects on bioactive compounds are unclear. There was studied the influence of HPH (150 MPa) and pasteurization (92 °C for 30 s and 85 °C for 15 s) processing on physicochemical properties and in vitro bioaccessibility of carotenoids and flavonoids in orange juices. Regarding fresh juice, physicochemical properties of samples remained unchanged although cloudiness was improved by homogenization. Pasteurization did not affect total carotenoids content and retinol activity equivalents (RAE) of juices whereas homogenization yielded a significant reduction (1.37 and 1.35-fold, respectively). Interestingly, particle size reduction from homogenization drastically enhanced (about 5-fold) bioaccessibility of carotenoids including hardly bioaccessible epoxycarotenoids, finding unaltered rates in pasteurized samples. Bioaccessibility of flavonoids was constant in all cases. Results can promote HPH as an efficient option to obtain health-enhanced foods.

In this study, the effects of high hydrostatic pressure (HHP)-mediated alterations in matrix composition on the bioaccessibility of carotenoids in satsuma mandarin juice were assessed. Results showed that the total carotenoid content increased significantly under HHP treatment (300-600 MPa), and the total carotenoids bioaccessibility was optimal at 600 MPa/1 min. The bioaccessibility of carotenoids in satsuma mandarin juice was positively correlated with the contents of titratable acids, total phenols and total sugars, all of which increased significantly after HHP.

Carotenoids, including β-carotene, lutein and lycopene, the 3 main carotenoids present in our body, are lipophilic phytochemicals associated with several health benefits. Dietary fibre may influence the bioavailability of carotenoids by altering their release from the food matrix and their solubilisation into mixed micelles during digestion and thus their subsequent absorption by enterocytes. We examined the dose-dependent influence of major soluble (pectin, guar, alginate, fructooligosaccharides,) and insoluble dietary fibres (cellulose, type-2 resistant starch) at nutritional relevant doses (0, 30 and 90 mg per 26 ml) added for digestion, containing also pure β-carotene, lutein or lycopene (at 75 μg) solubilized in peanut oil.

In this study, a combination of ultrasound and microwave technologies (USMW) was applied to increase the functional properties of L. (dill) juice and the obtained samples were comprehensively evaluated in terms of biofunctionality. Total phenolic content (TPC), -carotene, total chlorophyll, antioxidant capacity (FRAP) and antidiabetic enzyme inhibition (-glucosidase, α-amylase) were determined.

A novel mayonnaise product rich in cis (Z)-lutein was developed by natural garlic oil and heat treatment. The formula of the mayonnaise was as follows: 68 % soybean oil, 7 % garlic oil, 14 % egg yolk, 6 % white vinegar, 3 % white sugar, and 2 % edible salt. After heated at 50 °C for 1 h, the ratio of Z-lutein in the mayonnaise significantly increased from 11.

Lutein is a fat-soluble carotenoid with diverse biological functions, due to poor water solubility and environmental sensitivity limited it applications in food industry. In this study, β-Lactoglobulin (β-Lg)/γ-polyglutamic acid (γ-PGA) composite emulsion was developed to encapsulate lutein. The best composite was obtained when the ratio of β-Lg and γ-PGA was 1: 1, the β-Lg/γ-PGA composite solution at this ratio was used to encapsulate lutein oil.
