Abstract Alcalase hydrolyzates were prepared from the albumin (AH) and globulin (GH) fractions of eight chickpea ( Cicer arietinum L.) genotypes Mexico 10 other countries. Protein content, antioxidant activity (AA) (ABTS, DPPH), degree hydrolysis evaluated best genotype was selected by principal component analysis. The chosen analyzed for its antidiabetic potential measured as inhibition α‐amylase, α‐glucosidase, dipeptidyl peptidase‐4 (DPP4). Peptide profiles obtained liquid...

In the state of Sinaloa México, traditional farmers still cultivate maize accessions with a wide diversity morphological characteristics, but gene reservoir maintained in these populations has been poorly studied and it is being lost due to changes land use adoption hybrid commercial varieties. The aim this study was evaluate genetic some contribute their preservation. Twenty eight were used for analysis. DNA extracted from 396 individuals probed 20 microsatellites distributed across genome....

The formation of vitreous endosperm in quality protein maize (QPM) is associated with changes the composition and structure starch granules, but little known about role alterations activity main biosynthetic enzymes. Developing endosperms from K0326Y-QPM, W64Ao2, derived recombinant inbred lines were used to analyze ADP-glucose pyrophosphorylase (AGPase), granule-bound synthase (GBSS), starch-branching enzyme (SBE) pullulanase (PULL). GBSS correlated positively kernel vitreousness opposite...

The use of whey as a natural culture medium to produce hydrolysates with antimicrobial from Bacillus clausii is the objective this research. fermentation process was carried out at 25 ℃ for five days, where proteolytic activity, soluble peptides quantification, and activity using disc diffusion method were determined every day. fermented reached values ​​of between 90 260 U ml-1 production 100 2070 µg ml-1. maximum ​​were after three days all determinations. In addition, inhibition zone...

Pineapple slices were treated with three antioxidants and stored under passive modified atmosphere packaging (MAP) to evaluate the effect of these treatments on tissue browning (percentage dark area) accumulation ascorbic acid total phenolics. immersed in (AA), isoascorbic (IAA), N-acetylcysteine (NAC) solutions for 2 min, then packed at 5 °C air (AIR) or MAP 15 days. Water was used as control. The application IAA NAC reduced better index maintained a good quality slices. use AA increased...

Hot water treatment (HWT) of tomato (Solanum lycopersicum L.) fruit reduces the symptoms chilling injury (CI). The aim this study was to identify metabolites associated with HWT-induced CI tolerance in cv. Imperial. Mature green tomatoes HWT (42°C/5 min) and control were stored under conditions (5°C/20 days) then ripened (21°C/7 days). Methanol extracts from pericarp analyzed for total phenolics (TP), antioxidant activity (AoxA), metabolic profiling by UPLC-DAD-MS GC-MS. After cold storage...

The variability in grain and starch characteristics their relationship with the accumulation of granule associated proteins were investigated five maize landraces Northwest Mexico (Blando de Sonora, Chapalote, Elotero Sinaloa, Reventador, Tabloncillo). Significant differences observed hardness related traits, physicochemical properties, structural properties. Blando Sonora showed very soft grains, whereas hardest grains for Chapalote Reventador. Starch granules isolated from hard contained...

Eight Solanum lycopersicum var. cerasiforme accessions from Mexico were evaluated for total phenolics (TP) and flavonoids (TF), phenolic profiles (UPLC-DAD-MS), antioxidant capacity (AC) (ABTS, DPPH, FRAP), expression of transcription factors (MYB12 MYB14) target genes (PAL, CHS CHI) by RT-qPCR. The AC (mmol TE/kg fw; TE, Trolox Equivalents) ABTS (5.27–11.81), DPPH (1.43–3.67), FRAP (4.41–9.22) correlated with TP (0.53–1.20 g GAE/kg GAE, Gallic Acid Equivalents), TF (1.03–2.10 QE/kg; QE,...

Xylose is the second most abundant monomeric sugar on earth. Nevertheless, metabolizing xylose into ethanol a complex process due to several biochemical reactions. Some microorganisms of genus Mucor are suitable for this bioprocess. Using metal ions, such as zinc and calcium, allows some fungal species increase their yield. In work, wild strain spp. (C1502) was molecularly identified via internal transcribed spacer (ITS) sequencing. Secondly, an optimization using response surface...

Quality protein maize (QPM) was created converting the soft opaque-2 endosperm into a vitreous phenotype, but mechanisms involved in this modification are not completely understood. Recombinant inbred lines (RILs) derived from K0326Y QPM and W64Ao2 were used to identify quantitative trait loci (QTL) associated with starch physicochemical properties. RILs contrasting vitreousness also evaluate expression of biosynthesis genes. Mapping identified 5-6 QTLs for each that explained 66 %...

Protein quality maize (QPM) combines the protein of opaque-2 (o2) mutant with a vitreous endosperm. These characteristics have allowed breeding programs worldwide to produce QPM genotypes that help alleviate malnutrition people in developing countries from Africa, Asia and Latin America cereal-based diet. However, development these materials has been inefficient due limited knowledge about molecular basis conversion soft o2 endosperm into phenotype QPM. This associated an increase small...

Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a major pest of the tomato (Solanum lycopersicum L.) crop worldwide, mostly because resistance to insecticide that has been associated with endosymbionts. Although knowledge biotypes in B. complex and its endosymbionts critical for developing management strategies, limited information available on Culiacan Province Mexico. In total, 249 samples whiteflies were collected from plants four growers Valley analyze genetic identity PCR...
