Summary

This summary is machine-generated.

Nanoliposomes encapsulate marine bioactive compounds, enhancing their use in supplements. Whey protein concentrate coatings improved solubility and nutritional value, overcoming instability and taste issues for functional foods.

Area Of Science

  • Marine Biotechnology
  • Food Science and Technology
  • Nutraceuticals

Background

  • Growing demand for marine bioactive compounds in supplements and functional foods.
  • Challenges with marine compounds: instability, bitter taste, and digestive degradation.
  • Need for effective encapsulation methods to improve bioavailability and application.

Purpose Of The Study

  • To develop a functional supplement powder using nanoliposome encapsulation.
  • To encapsulate shrimp lipid extract, fish oil (FO), and fish protein hydrolysate.
  • To evaluate the physicochemical, nutritional, release, and sensory properties of the encapsulated compounds.

Main Methods

  • Nanoliposome encapsulation of marine bioactive compounds.
  • Coating nanoliposomes with chitosan and whey protein concentrate (WPC) in mono/bilayer and composite forms.
  • Freeze-drying for 72 hours, followed by physicochemical, nutritional, in vitro release, and sensory analyses.

Main Results

  • WPC-monolayer treatment showed highest solubility (28.83 mg/100 g) and encapsulation efficiency (97.67%).
  • Encapsulated products retained significant polyunsaturated fatty acids (PUFAs), with favorable amino acid profiles.
  • Higher compound release observed in intestinal conditions compared to acidic stomach conditions.

Conclusions

  • Encapsulation in liposomal carriers is a viable strategy for utilizing marine bioactive compounds in functional foods.
  • WPC-coated nanoliposomes offer improved stability, solubility, and nutritional benefits.
  • The developed supplement powder can meet daily nutritional requirements for essential amino acids and PUFAs when incorporated into foods like milk.
