Characterization of Myrosinase-Mediated Glucosinolate Degradation Pathways in ZUST49.

Cruciferous vegetables are rich in glucosinolates that can be hydrolyzed by myrosinase into isothiocyanates (ITCs) with significant anticancer properties. In the absence of bacterial myrosinase, glucosinolates are excreted from the body in their inactive forms. However, the mechanisms underlying the bacterial breakdown of glucosinolates are not well understood.

Removing internal lipids influences the interactions between blueberry anthocyanins and maize starch: Thermal and rheological properties, and digestibility.

The interactions between blueberry anthocyanins (BA) and waxy (WMS) and normal amylose (NMS) maize starches before and after internal lipids removal were studied. With the addition of BA (0-10 %), gelatinization enthalpy (ΔH) of both WMS and NMS decreased, and ΔH of the starches without internal lipids was further reduced. Steady shear rheological analysis indicated that removing internal lipids reduced consistency coefficient (K) and increased flow behavior index (n) of NMS-BA complexes, while this was not observed in WMS-BA complexes.

Interpenetrating network hydrogels loaded with nanostructured lipid carriers for curcumin delivery: Impact of dual crosslinking with genipin and calcium ions.

Interpenetrating network hydrogels (IPNs) gained significant attention for applications in food structure modification and nutraceutical delivery.

Effect of Different Harvest Time and Microwave Aging on Aroma Characteristics of Japanese Apricot Wine.

The aroma and nutrition of Japanese apricot fruit change continuously as the fruit ripens. The differences in fruit aroma and nutrition can affect the resulting wine, which is produced by steeping the Japanese apricot fruit. In this study, we used HS-SPME-GC-MS to examine the aromatic compositions of Japanese apricot fruit and wine produced from its macerated fruit at different levels of ripeness.

Preparation of a biodegradable packaging film by konjac glucomannan/sodium alginate reinforced with nitrogen-doped carbon quantum dots from crayfish shell for crayfish meat preservation.

The development of biomass material is an important approach to alleviating the excessive using of plastic packaging, by which the product could be more environmentally friendly and lower toxicity. In this study, we developed a biodegradable photodynamic antibacterial food packaging film using nitrogen-doped carbon quantum dots (N-CQDs) synthesized from crayfish shells, combined with konjac glucomannan (KGM) and sodium alginate (SA). Casting method was used to prepare the composite film and results indicated that incorporation of N-CQDs significantly enhanced the mechanical and barrier properties of the film by reducing the number of micropores.

Stabilizing effect of Leuconostoc mesenteroides Lm10 produced dextran in situ on stirred soy yogurt: Structure-function relationship.

Stirred soy yogurt as a dairy alternative is widely accepted among consumers, but its poor stability has been an urgent problem. We found that Leuconostoc mesenteroides Lm10 produced dextran reduced water mobility and improved the water holding capacity of stirred soy yogurt, especially with over 4 % sucrose added which could completely prevent whey separation. With the increase of dextran content, the particle size of stirred soy yogurt was significantly decreased, accompanied by the improvement of viscoelastic behaviors and resistance to deformation.

Removal of internal lipids enhances the effect of proanthocyanidins on maize starch retrogradation.

Internal lipids of normal amylose (NMS) and two high amylose (HMS56, HMS72) maize starches were removed to investigate the effect of proanthocyanidins (PA) on starch short-term (1 d) and long-term (21 d) retrogradation. Removal of internal lipids decreased the degree of retrogradation in PA-starch complexes after 1 d and 21 d retrogradation. The relative crystallinity (RC) of PA-NMS, PA-HMS56 and PA-HMS72 without internal lipid complexes after short-term retrogradation decreased by 5.

Influence of pH on the emulsifying property of high methyl-esterified citrus pectin in the presence of calcium cations.

High methyl-esterified citrus pectin (HMCP) is often used as a thickness in food products and is considered a poor emulsifier, especially in neutral pH solutions. Our previous findings show that the emulsifying capacity of HMCP could be significantly enhanced by calcium cations. Besides, the pH of the solution decreased in the presence of calcium cations.
