“…The reasons underlying this trend lie in the unique structural characteristic of CDs, which possess a lipophilic central cavity and hydrophilic outer surface, facilitating to increase the inferior solubility of the included bioactive substance [ 13 ]. Alpha−cyclodextrin (α−CD) is one type of oligosaccharide consisting of six glucose units [ 14 ], the inclusion property of which has been proved application potential in food, medicine, and cosmetics [ 15 ]. α−CD encapsulation of moringa isothiocyanate promoted aqueous solubility and stability, which in turn exhibited a higher efficacy in suppressing the neuroblastoma cell proliferation than solely applying the ITC compound [ 16 ].…”

A bioactive packaging material based on chitosan (CS) incorporated with benzyl isothiocyanate (BITC) and α−cyclodextrin (α−CD) was fabricated to evaluate its preservative effects on fresh beef stored at 4 °C for 12 d according to the quality analysis. The Fourier-transform infrared (FTIR) spectrum revealed that the major structural moiety of BITC was embedded in the cavity of α−CD, except for the thiocyanate group. FTIR and X-ray diffraction analysis further verified that intermolecular interactions were formed between the BITC−α−CD and CS film matrix. The addition of BITC−α−CD decreased the UV light transmittance of pure CS film to lower than 63% but still had enough transparency for observing packaged items. The CS−based composite film displayed a sustainable antibacterial capacity and an enhanced antioxidant activity. Moreover, the total viable counts, total volatile base nitrogen, pH, thiobarbituric acid–reactive substances, and sensory evaluation of the raw beef treated with the CS−based composite film were 6.31 log colony-forming unit (CFU)/g, 19.60 mg/100 g, 6.84, 0.26 mg/kg, and 6.5 at 12 days, respectively, indicating the favorable protective efficacy on beef. These results suggested that the fabricated CS−based composite film has the application potential to be developed as a bioactive food packaging material, especially for beef preservation.

“…The linear response of the sensor was compared to other works reported in the literature for the detection of THBA (Table 1). 7,[12][13][14][15][16]18,20,22,[58][59][60][61][62] It is observed that, concerning the techniques presented in Table 1, the proposed method showed satisfactory results, since it can be used successfully in the determination of THBA. It is also important to emphasize that the proposed method does not involve co-precipitation steps, flow injection, and it does not require large amounts of samples, being easy to prepare and operate.…”

“…In this sense, the development of novel methodologies requiring a small amount of sample and low-cost instrumentation has attracted the interest of several research groups. [8][9][10][11] In this sense, several methods have been reported for the determination of THBA, such as chromatography analysis, 12,13 flow injection analysis, 14,15 spectrophotometric determination, 16,17 chemiluminescence, 18 and electrochemical methods. 7,[19][20][21][22] The electrochemical methods show high versatility, sensitivity, low cost and low volume of reagents, and they can be performed fast.…”

The present work is based on the development and application of a photoelectrochemical method for the amperometric determination of 3,4,5-trihydroxybenzoic acid in different samples. The method is based on the use of a photoelectrochemical platform based on a glass slide coated with fluorine-doped tin oxide, which has been modified with cadmium sulfide and poly(D-glucosamine) and subjected to a light-emitting diode (LED) lamp. The photoelectrochemical platform was sensitive to the increase of the concentration of the antioxidant 3,4,5-trihydroxybenzoic acid in the solution. Under the optimized experimental conditions, the photoelectrochemical method presented a linear response for a 3,4,5-trihydroxybenzoic acid concentration ranging from 0.2 up to 500 μmol L-1. The method was applied to 3,4,5-trihydroxybenzoic acid determination in samples of wines and teas with recoveries between 95.88 and 101.72%. The results obtained suggest that the developed platform is a promising tool for quantifying the 3,4,5-trihydroxybenzoic acid.

“…Gallic acid (GA) is a potent antioxidant and anti-inflammatory agent; however, it has been reported to be unstable in body fluids with alkaline pH, 7.4 and 8.3, or in the presence of oxygen or light . The encapsulation of GA by α-cyclodextrins has been reported at acidic pH and assisted by ultrasound . The α-cyclodextrins form hydrophobic inner channels similar to amylose helices with 6 α- d -glucopyranoside units.…”

“…11 The encapsulation of GA by α-cyclodextrins has been reported at acidic pH and assisted by ultrasound. 12 The α-cyclodextrins form hydrophobic inner channels similar to amylose helices with 6 α-D-glucopyranoside units. High amylose corn starch also forms inclusion complexes with alkyl gallates, and this supramolecular structure delays starch digestion, which is attractive for slow and sustained release of bioactive guest compounds into the gastrointestinal tract.…”

Donut-shaped microparticles were prepared from starches of different botanical sources by heat-mixture-alcoholic treatment. C-type starch allomorphs: pea, Araucaria araucana, and Aesculus hippocastanum were used for the preparation of the microparticles. The microparticles were characterized and evaluated as a carrier of phenolic compounds. The gallic acid encapsulation efficiency was determined, and its antioxidant activity was evaluated using spectrophotometric assays. The starch microparticles exhibited a round to elongated shape, with a central concavity, similar to donut-shaped microparticles. In the loaded and unloaded starch microparticles, B-type and V-type polymorphs coexist. The entrapment of gallic acid in starch microparticles is due to hydrogen-bond formation and not to an amylose inclusion complex. The loaded pea starch microparticles showed lower onset and peak gelatinization temperature with respect to their unloaded counterpart, which is associated with the decreased stability of formed crystallites. The percentage of phenolic compounds encapsulated depended on the native starch precursor. Pea starch microparticles loaded with gallic acid showed the highest encapsulation efficiency around 45%. Gallic acid entrapped in starch microparticles showed no loss of antioxidant activity. Starch microparticles are a food-grade solid matrix suitable as carriers for active compounds.
