“…Lecithin is usually modified or fractionated to have tailor-made lecithin that is suitable for the processing and characteristics of food products. The chemical modification of PL is aimed to improve emulsifying properties by means of acid or basecatalysed hydrolysis, acetylation, hydroxylation, and hydrogenation (Li et al, 2019). Modification by enzyme is used to liberate fatty acid from sn-1 or sn-2 of the glycerol backbone of PL, resulting in better emulsifying properties for o/w emulsion (Estiasih et al, 2013).…”

Palm pressed fibre (PPF) is a by-product of crude palm oil (CPO) extraction and has great potential as a source of phospholipids (PL). PPF was extracted from chloroform:methanol to extract total lipid, and polar lipid was separated using methanol. PL from PPF was fractionated by ethanol, and subsequently, the ethanol-soluble fraction was fractionated by acetone. Four fractions were obtained: ethanol-soluble, ethanolinsoluble, ethanol-acetone soluble, ethanol soluble-acetone insoluble. All fractions had different PL molecular species compositions. Different compositions of PL in the fractions resulted in different hydrophilic-lipophilic balance (HLB) values, emulsifying properties, and antioxidant activity. HLB value of crude PL from PPF was 6.07 that was suitable for water in oil (w/o) emulsion indicated by low emulsifying activity index (EAI) and emulsion stability index (ESI) in oil-water (o/w) emulsion systems. Ethanol-soluble and ethanol-acetone soluble fractions exhibited better emulsifying properties and higher HLB values of around 10. Crude PL and its fractions showed a potential antioxidant activity to prevent bulk soybean oil in a single antioxidant system. Synergism with α-tocopherol appeared in a binary antioxidant system indicated by low peroxide value compared to the single one. PL composition affected the ability of PL fractions as antioxidants.

“…The major phospholipids are phosphatidylcholine (PC) (Figure 2), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and phosphatidylinositol (PI) [120]. The presence of both hydrophilic head groups and hydrophobic tails confers them amphiphilicity, which makes phospholipids excellent emulsifying agents and therefore can stabilize oil-water emulsions as delivery systems for food, cosmetic ingredients, and drugs [121]. Lecithins are a complex mixture of PC, PE, phosphatidylserine (PS), and PI, combined with various amounts of other substances such as triglycerides, fatty acids, and carbohydrates.…”

In recent years, there has been considerable interest in using microalgal lipids in the food, chemical, pharmaceutical, and cosmetic industries. Several microalgal species can accumulate appreciable lipid quantities and therefore are characterized as oleaginous. In cosmetic formulations, lipids and their derivatives are one of the main ingredients. Different lipid classes are great moisturizing, emollient, and softening agents, work as surfactants and emulsifiers, give consistence to products, are color and fragrance carriers, act as preservatives to maintain products integrity, and can be part of the molecules delivery system. In the past, chemicals have been widely used but today’s market and customers’ demands are oriented towards natural products. Microalgae are an extraordinary source of lipids and other many bioactive molecules. Scientists’ attention to microalgae cultivation for their industrial application is increasing. For the high costs associated, commercialization of microalgae and their products is still not very widespread. The possibility to use biomass for various industrial purposes could make microalgae more economically competitive.

Lignin nanoparticles (LNPs) are promising components for various materials, given their controllable particle size and spherical shape. However, their origin from supramolecular aggregation has limited the applicability of LNPs as recoverable templates for immobilization of enzymes. In this study, we show that stabilized LNPs are highly promising for the immobilization of phospholipase D (PLD), the enzyme involved in the biocatalytic production of high‐value polar head modified phospholipids of commercial interest, phosphatidylglycerol, phosphatidylserine and phosphatidyl‐ethanolamine. Starting from hydroxymethylated lignin, LNPs were prepared and successively hydrothermally treated to obtain c‐HLNPs with high resistance to organic solvents and a wide range of pH values, covering the conditions for enzymatic reactions and enzyme recovery. The immobilization of PLD on c‐HLNPs (PLD‐c‐HLNPs) was achieved through direct adsorption. We then successfully exploited this new enzymatic preparation in the preparation of pure polar head modified phospholipids with high yields (60‐90%). Furthermore, the high PLD‐c‐HLNPs stability allows its recycling for a number of reactions with appreciable maintenance of its catalytic activity. Thus, PLD‐c‐HLNPs can be regarded as a new, chemically stable, recyclable and user‐friendly biocatalyst, based on a biobased inexpensive scaffold, to be employed in sustainable chemical processes for synthesis of value‐added phospholipids.
