“…The TPC results for the different PFPP samples (382.86–428.71 µg GAE/g DM) showed no significant differences ( p > 0.05), suggesting that the type of carrier did not affect the entrapment of the polyphenols ( Figure 4 a). However, previous studies on eggplant extract, Hibiscus sabdariffa (Roselle) extracts, mulberry juice, Crotalaria longirostrata (chipilin) leaf extract, and Arctium lappa L. root extracts have supported GA and MT as better carrier agents to bind and preserve polyphenols from plant extracts [ 12 , 47 , 48 , 49 , 50 ].…”

Micro-Encapsulation of Phytochemicals in Passion Fruit Peel Waste Generated on an Organic Farm: Effect of Carriers on the Quality of Encapsulated Powders and Potential for Value-Addition

The passion (Passiflora edulis Sims) fruit peel is rich in phenolics and other bioactive compounds and has great potential as a natural food preservative. The present study investigated the value-adding potential of passion fruit peel waste generated on an organic farm. The effect of carriers in encapsulating the peel extract to develop a polyphenolic-rich powder was investigated. The passion fruit peel extracts were prepared using 70% ethanol (1:10 w/v), and encapsulated using waxy starch (WS), gum arabic (GA), and maltodextrin (MT) before freeze-drying. The effects of carriers on the passion fruit peel powder (PFPP) production yield, physicochemical, rheological, phytochemical, and antioxidant properties were investigated. GA-and MT-encapsulated powders had better physical, phytochemical, and antioxidant properties, including yield, total soluble solids, solubility, bulk density, total phenolic content, and ferric reducing antioxidant powder. A total of 18 metabolites, including phenolic acids (10), flavonoids (6), and stilbenes (2), were tentatively identified in all the PFPP samples, with WS exhibiting a higher concentration of the compounds compared to GA and MT. Our results indicated that no single carrier was associated with all the quality attributes; therefore, better results could be produced by compositing these carriers. Nonetheless, our results highlight the potential of passion fruit peels as a source of polyphenols and functional ingredient in formulating natural food additives.

“…Nevertheless, different results are reported in the literature. In a previous study including GA, MT and tapioca starch, the TMA of GA-and MT-encapsulated acai powders were higher than that of tapioca starch [ 50 ]. The authors explained that the lowest concentration of TMA in tapioca starch was because of the insolubility of the material.…”

“…Regarding the assessment of the spray drying microencapsulation assessment, an evident decrease in the antioxidant activity of the extracted microencapsulates was observed compared to the extract. This might be due to the high injection temperature in the drying process causing the degradation of compounds like phenolics and subsequently the antioxidant capacity [52], as well as the amount of the T. stans sample used in the extract. Nonetheless, encapsulation with MD was able to preserve considerably better the extract antioxidants in both radicals (9.89 ± 0.82 mg Trolox/g d.s.…”

Bioactive compounds from medicinal plants have applications in the development of functional foods. However, since they are unstable, encapsulation is used as a conservation alternative. This work aimed to assess the bioactive properties (antioxidant and hypoglycemic) of different extracts, including the infusion, as well as their spray-dried microencapsulates from Tecoma stans leaves. A factorial design was proposed to determine the best extraction conditions, based on ABTS and DPPH inhibition. Maltodextrin (MD), arabic gum (AG), and a 1:1 blend (MD:AG) were used as encapsulating agents. Moreover, characterization through physicochemical properties, gas chromatography/mass spectrometry (GC-MS) and scanning electron microscopy (SEM) of the best two powders based on the bioactive properties were analyzed. The results showed that the combination of stirring, water, and 5 min provided the highest inhibition to ABTS and DPPH (35.64 ± 1.25 mg Trolox/g d.s. and 2.77 ± 0.01 g Trolox/g d.s., respectively). Spray drying decreased the antioxidant activity of the extract while preserving it in the infusion. The encapsulated infusion with MD:AG had the highest hypoglycemic activity as it presented the lowest glycemic index (GI = 47). According to the results, the microencapsulates could potentially be added in foods to enhance nutritional quality and prevent/treat ailments.

“…The moisture content significantly increased with an increased W 2 phase and GA content. The MCs produced with GA had the higher moisture content due to the high hygroscopicity of GA which has hydrophilic groups and therefore binds to water molecules, which prevents it from escaping (Esmaeili et al, 2022). The a w is an essential index to determine the shelf life of MCs and it is related to the moisture content.…”

Importance of the work: Nisin, a 'generally recognized as safe' natural antimicrobial agent, has poor antimicrobial activity against Gram-negative bacteria and is easily combined with food components. Objectives: To enhance the antimicrobial activity of nisin against Gram-negative bacteria and to prolong its antimicrobial activity using an encapsulating-technique. Materials & Methods: Nisin (N) was combined with ascorbic acid (A) and ethylenediaminetetraacetic acid (EDTA, E) at final concentrations of 500 parts per million (ppm), 2,000 ppm and 250 ppm, respectively. Subsequently, double emulsion and freeze-drying techniques were applied to encapsulate the N-A-E mixture to decelerate their release and prolong their antimicrobial activity in culture broth and a minced fish sample. Results: Besides Gram-positive bacteria, the N-A-E mixture reduced Gram-negative bacteria by 24.74-100%. The obtained microcapsules (MCs) had a smooth surface and spherical morphology with values for moisture content, water activity and production yield of 1.33-5.51%, 0.248-0.402% and 84.00-98.76%, respectively. The MCs prepared using a ratio of maltodextrin-to-gum arabic of 1:1, with a ratio of primary emulsion-to-outer aqueous phase of 1:9 (weight per weight), produced the highest encapsulation efficiency (p < 0.05) of nisin (44.40%). The MCs could completely inhibit Salmonella Enteritidis ATCC 13076 in culture broth (4.85 log CFU/mL) after 4 d of incubation and also exhibited gradual release. In addition, the MCs had an antibacterial effect on minced fish by reducing S. Enteritidis ATCC 13076 by 1.5 log CFU/g after storage at 4 °C for 8 d. Main finding:The N-A-E mixture using an encapsulation approach showed potential as an alternative scheme to address the confined application of nisin in the food industry.
