Abstract:
The monofloral avocado honey (AH), characterized by its dark amber color, contains a higher level of bioactive compounds than the multi-floral honey; these characteristics qualify it as a possible sweetener alternative for domestic use. Therefore, the purpose of the present study was to assess the effect of the consumption of avocado honey (25 g/day) on anthropometric and biochemical parameters in healthy subjects for 4-weeks. Thirteen healthy subjects (control group: n = 7 or honey group n: 6) aged 25–50 years, with BMI (body mass index): <25 kg/m2 completed the study (ClinicalTrials.gov: NCT04572607). There was no significant difference in BMI and body fat percentage. Likewise, no effects on fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were detected. These data suggest that AH might be as effective as a functional food or natural sweeter without negatively influencing anthropometric and biochemical parameters.

Abstract:
The present study was to investigate whether agavins supplementation might reduce obesity in mice fed with a high fat-high sucrose (HF-HS) diet. Mice were fed with a HF-HS diet with (HF-HS+A) or without agavins (HF-HS) supplementation. Body weight, white adipose tissue (WAT), biomarkers inflammation, gastrointestinal hormones, microbiota, and their excreted metabolites were evaluated. HF-HS+A mice significantly reduced body weight, WAT, and leptin levels compared to the HF-HS group. Furthermore, pro-inflammatory cytokines and insulin levels tended to be lower in the HF-HS+A group. Moreover, the genera Allobaculum, Akkermansia, and Sutterella, linked with positives effects on host health, were identified as possible biomarkers for agavins treatment; meanwhile, ethyl oleate, thymine, hypoxanthine, uracil, and some fatty acids were substantially enriched with agavins and negative associated with pro-inflammatory biomarkers. Collectively, these results demonstrate that agavins can ameliorates many of the harmful effects induced by intake of a diet with a high fat and sucrose content.

Abstract:
In this study, avocado pulp and oil were added to mayonnaise type-dressing to produce a healthy and microbiologically safe product with improved sensory properties. First, oil avocado was obtained by solvent-free ultrasonic-assisted extraction and centrifugation. The mayonnaise type-dressing was formulated with avocado pulp and oil and then treated with ultrasound. Chemical and sensory qualities were determined in the oil. Microbiological quality, color and sensory analysis were carried out in the mayonnaise type-dressing along a storage period under refrigeration. The avocado oil yield was 64% with an outstanding emerald green color. The avocado oil quality agreed with Mexican Official Standards. Oleic, palmitic, palmitoleic and linoleic acids were found to be the major fatty acids in avocado oil. The mayonnaise-type dressing showed a reduction of the microbial load without the need for thermal pasteurization, and the green color was stable during storage. Color, odor and flavor were sensorially evaluated as “like much.”

Abstract:
Litopenaeus vannamei easily blackens during cold storage. To inhibit blackening and improve the storage quality of prawns, in this study, konjac glucomman (KGM)-epigallocatechin gallate (EGCG) topological microgel was formed and used for storage and preservation of prawns to improve their antioxidant properties. The effect of KGM-EGCG topological microgel on inhibiting shrimp blackening was studied by measuring the sensory evaluation score, pH value, TVB-N value, K value, PPO activity, and the effect of changes in the total number of bacteria of KGM-EGCG-treated prawns during storage. SEM and FTIR results showed that during the KGM-EGCG binding process, the number of hydrogen bond connections and the intermolecular force increased. Results also showed that the KGM microgel can effectively embed EGCG and enhance its stability to achieve a better controlled release effect. Compared with the EGCG group and untreated group, KGM-EGCG microgel has better anti-PPO activity and can better maintain the organoleptic quality and inhibit bacterial growth of Litopenaeus vannamei. Therefore, the KGM-EGCG microgel could slow down the increase in pH value, the production of volatile base nitrogen, and the increase in K value, and effectively extend the shelf life of Litopenaeus vannamei from 3 d to 6 d, providing a theoretical basis for the research of KGM functional gel and a reference for the deep processing and value enhancement of green tea and shrimp.

Abstract:
Seven different methods of DNA extraction were performed and compared in order to have the better DNA recovery in terms of quality and quantity. A PCR assay was realised based on the Cytb mitochondrial gene to identify 53 commercial food products of wide range diversity (Scombridae Thunnus species) commercialised in the Tunisian market, and we checked whether these products were correctly labelled under European and national legislations. Phylogenetic analyses on Cytb mitochondrial gene were used to study the relationships among the considered species. Tuna species was easily differentiated and confirmed by direct sequencing. The results showed a high deficiency in labelling: 96% of canned tuna did not specify the species, although the name of the species had to be mentioned. Partial least squares regression (PLS) showed relatively high values (45%) in all analysed data, suggesting substantial difference between the extraction procedures and matrices with SDS/PCI method being the most convenient.

Abstract:
The objective of this study was to incorporate avocado peel (AEE) and coconut (CEE) extracts as antifungal additive in the development of gelatin and carboxymethylcellulose coatings to extend shelf life in strawberries. Fractions of 200 mg/L of extracts were incorporated in the coating and characterized during storage at 2°C. AEE and CEE in the coating delayed significantly (P< .05) weight loss (40%), softening, color, and compositional changes (°Brix, sugars, titratable acidity). Rhizopus stolonifer and Aspergillusniger strains were isolated and inoculated to evaluate the effectiveness of the coatings on strawberries. The use of the coating + plant extracts decreased the proliferation of fungi by 45% compared to the uncoated fruit and extended the shelf life for 15 days. With these findings, it is suggested that biopolymeric coatings + plant extracts can be used as a potential method of ecological preservation in strawberries against microbial deterioration.

Abstract:
The objective of this study was to evaluate the application of hot water treatment to tomato fruits (Solanum lycopersicum cv. TA234) genetically modified with silencing of the TomloxB gene. Unmodified and genetically modified tomato fruits were immersed in water at 40°C for 10, 20 and 30 seconds. Subsequently, fruits were stored at 25°C for 18 days. Physiology was assessed and electrolyte leakage, lipoxygenase and polygalacturonase activities were monitored. Treatment applied to the genetically modified tomatoes at 40°C for 30 seconds, resulted in slower ripening, decreased metabolic activity and maintained the attributes in optimal conditions for longer time, increased the postharvest life of the genetically modified tomatoes until 18 days. Lipoxygenase and polygalacturonase activities were partially inhibited.

Abstract:
This work investigated the effects of calcium chloride (CaCl2) as sodium replacement on the physicochemical properties of silver carp surimi. As NaCl replaced by 0.32% and 0.63% CaCl2, surimi gels presented better textural properties, breaking force and rheological properties, while 0.95%, 1.27% and 1.58% CaCl2 led to the deterioration of gel strength. With the addition of CaCl2, water holding capacity (WHC) decreased significantly (p< .05), the T23 relaxation time decreased and the proportion of T23 increased. Compared with control, the sulphydryl content in surimi gel with 0.63% CaCl2 increased by 23.61% and the solubility decreased by 17.31%. Furthermore, the Raman spectra data demonstrated that more β-sheet structures and random coils were induced in surimi gels prepared with CaCl2. Then surimi with and without CaCl2 was used as food-ink for three-dimensional (3D) printing, it indicated that surimi with 0.32% and 0.63% CaCl2 could effectively improve the 3D printability.

Abstract:
The Leucaena leucocephala seeds (LLS) cotyledon proteins, globulins, and glutelins were independently hydrolyzed by Alcalase, Trypsin, and α-Chymotrypsin up to 180 min. The degree of hydrolysis (DH), antioxidant, ACE-inhibitory, and α-Amylase inhibition were assessed. The higher DH values were 76.75% and 82.71% for globulin α-Chymotrypsin, and glutelin Alcalase hydrolysates, respectively. The glutelin hydrolyzed with Trypsin showed the higher DPPH antioxidant activity while the higher ABTS antioxidant activity was for globulin Alcalase hydrolysate after 180 min digestion. The highest ACE-inhibitory activity was 95.44% for globulin-Alcalase hydrolysate at 180 min; while, for the α-Amylase inhibition assay, glutelin-Alcalase showed the highest values at 100 min of reaction. LLS cotyledon protein concentrates and hydrolysates with relatively low mimosine content were obtained after protein extraction. Such findings indicate the possibility of getting bioactive peptides from LLS cotyledon proteins using enzyme digestions and might be utilized for functional foods with physiological enhancer effects.
