The present invention discloses a β-carotene-grape seed extract eye-care preparation for retinal protection, relating to functional health foods. The preparation comprises active components and food-acceptable excipients. In parts by weight, the active components include 1–4 parts lutein, 0.5 –2 parts meso-zeaxanthin, 2 – 6 parts β-carotene, 8 – 25 parts blueberry extract, 5 – 18 parts grape seed extract, 0.2–1 part L-ergothioneine, 0.5–3 parts saffron extract, and 1–5 parts phosphatidylserine. The excipients comprise a filler, disintegrant, binder, and lubricant, with a weight ratio of active components to excipients of 1:1 to 1:4. By combining these eight components at specific ratios, the invention achieves synergistic effects, protects retinal health, and reduces blue-light damage. Dual-phase microencapsulation based on solubility, together with standardized preparation steps, improves stability and utilization efficiency.

This invention provides a low glycemic index blueberry extract and its preparation method, belonging to the field of beverage processing technology. The preparation method includes the following steps: blueberries are pulped, then fermented using a compound strain of Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium, filtered through a membrane filtration device to obtain a blueberry fermentation broth; blueberries are crushed, the pH of an ethanol solution is adjusted to 2-3 with citric acid, followed by ultrasonic extraction, centrifugation to collect the supernatant, and then vacuum distillation of the supernatant to obtain anthocyanin extract concentrate; the anthocyanin extract concentrate is freeze-dried to obtain anthocyanin extract dried product; the anthocyanin extract dried product and blueberry fermentation broth are mixed evenly at a mass-volume ratio of (0.2-0.3) g:1L, then maltitol is added to adjust acidity and sweetness, homogenized, filtered, and sterilized to obtain the blueberry extract. By using compound probiotic fermentation to reduce sugar content and combining it with alcohol extraction to enhance anthocyanins and improve efficacy, the resulting product has anthocyanin content ≥400 mg / L and a low GI.

The application discloses a kind of composite plant extract eye drops for relieving eye fatigue and a preparation method thereof, and relates to the technical field of ophthalmic preparations.The eye drops of the present application use lutein, zeaxanthin, blueberry extract, peppermint essential oil and borneol as fat-soluble active ingredients, and use phospholipid and poloxamer 188 as a composite nanocarrier, in combination with sodium hyaluronate, sodium chloride and a buffer system, a bacteriostatic system to form the eye drops.The present application uses a film hydration combined with high-pressure homogenization process to produce clear and transparent, thermodynamically stable eye drops, which solves the problems of low solubility, easy oxidative degradation and poor bioavailability of fat-soluble ingredients, improves the concentration and retention time of active ingredients in the eye, and the synergistic effect of various plant extracts can effectively relieve the symptoms of eye fatigue caused by long-term eye use, such as dryness, acid swelling, blurred vision and ciliary spasm, without eye irritation and with high stability.
