This study aimed to optimize extraction process using deep eutectic solvents composed choline chloride lactic acid. The focused on three key factors: solvent-to-material ratio, temperature, time, employing response surface methodology with central composite design. results showed that optimal conditions were achieved at ratio 25:1 (v · w-1), an...

Coffee pulp is an abundant residue from the coffee industry, but it still contains large amounts of valuable compounds such as polyphenols. The extraction polyphenols by conventional method accompanied contaminated compounds. This study, therefore, applied aqueous two-phase system consisting different ratios ethanol/ammonium sulfate to eliminate impurities coffee-pulp crude extract. purification efficiency was evaluated via total polyphenol content, antioxidant activity and two major in...

This article investigates the stability of oil – in water double emulsions (sunflower oil/water/palm oil) with various concentrations (40-50-60%, w/w) presence some biopolymers. Double were prepared using Ultra Turrax homogenizer followed by fast crystallization. The results study revealed high O/W/O at 5 °C can be achieved combining sodium caseinate (SC), k-carrageenan (KC) soy lecithin. appropriate time for cold homogenization is 15 minutes speed 5000 rpm.

The objective of this study was to determine the impact extraction conditions on yield bioactive compounds from grape pomace using choline chloride and organic acid-based deep eutectic solvents (DES). Three different types DES were used, including chloride-lactic acid, chloride-malic chloride-citric acid. effect ratios hydrogen bond acceptor donor (2:1, 1:1, 1:2, 1:3), water addition in (10–35%), solid-to-solvent ratio (1/15–1/30 (w/w)), time (1.5–4 hours) also investigated. results showed...

Peristrophe bivalvis (L.) Merr. (Acanthaceae) is a Vietnamese herb that rich in anthocyanin, natural colorant. However, the common extraction methods for this pigment often accompany with presence of contaminated compounds. This study, therefore, focused on applying aqueous two-phase system (ATPS), green method extracting and purifying anthocyanin leaf extract. The obtained results revealed an ATPS composing from ethanol ammonium sulfate concentrations 32.5% 25%, respectively, can recover...

Abstract Coffee pulp, the major by‐product of beverage industry, is considered as an environmental threat, but also possesses high amounts bioactive compounds. The extraction these compounds by using conventional methods and solvents usually accompanies impurities. Here, aqueous two‐phase system (ATPS) was optimized to extract purify polyphenols from coffee pulp. Key affecting factors include phase composition (ethanol ammonium sulfate), time temperature while quality product evaluated based...

The application of Pickering emulsions is a common trend in the food, cosmetic and pharmaceutical industry. Among biopolymers stabilizing emulsion, rice maltodextrins (RMD) are considered as most potential material due to their convenience, non-toxicity affordable cost. This study, therefore, combined producing by α-amylase (of Aspergillus oryzae) with sodium caseinate formulate bran oil-in-water (RBO/W) emulsions. effect various (with dextrose equivalent 5.4, 7.6, 11.0, 12.8, 14.5) on...

Lyotropic liquid crystals (LLCs) are interesting wall-materials for encapsulation technology, in which monoacylglycerols (MAGs) considered as potential ingredient LLC formulation. This study, therefore, applied palm oil-based MAGs to encapsulate Gac fruit oils and compared the effect of two drying methods (freeze-drying spray-drying) on quality products during storage. Wall-materials were prepared by ultrasound dispersing MAGs/water mixtures (40/60, w/w) into Pluronic solution (2%, formulate...

This study was conducted to determine the physico-chemical properties and biological activity of honey collected from Tan Phu Dong Cai Be districts Tien Giang province, Vietnam. The results showed that 19% 20% moisture content district had viscosities 1075 Cp 1013.33 Cp, insoluble solid contents 0.12% 0.09%, acidities 32.49 mg/1000 g 30.49 g, diastase index 4.5 Schade 4.09 Schade, free reducing sugar 65% 67%, HMF 0.98 mg/100 0.86 antioxidant 0.47 0.52 mg vitamin C equiv./mg dry wt,...

Abstract Lyotropic liquid crystals (LLCs) made of monoacylglycerols (MAGs) are rich in potential for food and pharmaceutical applications but the understandings these materials quite limited. This study, therefore, precisely demonstrated formation some LLCs based on combination two palm oil‐based MAGs (distilled non‐distilled) with water a triblock copolymer (Pluronic F127). X‐ray diffraction results showed that main lyotropic mesophase obtained from was lamellar phase (L α ) while dynamic...
