Abstract
Purpose
The purpose of this study was to development of a new chocolate-flavored powdered food supplement enriched with mesquite pod flour, oak extract and agave fructans, with proper sensory characteristics as well as its physicochemical and glycemic quality.
Design/methodology/approach
A powdered shake was formulated using experimental design (23) with mesquite (Prosopis laevigata) pod flour, oak (Quercus convallata) extracts, nonalkalinized cocoa, agave fructans, milk protein and xanthan gum. Sensory analysis (choice profile method, ranking test, focus group, quantitative descriptive analysis), moisture, ash, fiber, protein and lipids, pH, color, wettability, dispersibility and rheological tests were done. Phenolic profiling analysis to samples was done by ultraperformance liquid chromatography coupled to photodiode array detection and electrospray ionization tandem mass spectrometry, antioxidant activity was measured by 2,2’-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation, ferric reducing antioxidant power and oxygen radical absorbance capacity, glycemic index (GI) and glycemic load were evaluated.
Findings
The main sensory attributes in the powders were chocolate, bitter, astringent, grass/linseed flavors (p < 0.05). The product has protein [66.9%], carbohydrates [22.0%], lipids [1.6%], ash [2.7%] and moisture [6.8%], with wettability (23 s), and dispersibility of 77.9%. Catechin, epicatechin, gallocatechin, procyanidin B2, chlorogenic, coumaric and ferulic acids were identified. GI and caloric load not show differences between men (73.3±2.4, 4.4±0.1) and women (67.0±2.1, 4.1±0.1) (p > 0.05).
Originality/value
The use of mesquite pods, oak and agave fructans in powder food supplement is an alternative to obtain a product high in protein, with good sensory properties, antioxidant activity and moderate GI.

Abstract
Purpose
The present work aims to prepare biocomposites blend based on linear low density polyethylene/ starch without using harmful chemicals to improve the adhesion between two phases. Also, the efficiency of essential oils as green plasticizers and natural antimicrobial agents were evaluated.
Design/methodology/approach
Barrier properties and biodegradation behavior of linear low density polyethylene/starch (LLDPE/starch) blends plasticized with different essential oils including moringa oleifera and castor oils wereassessed as a comparison with traditional plasticizer such as glycerol. Biodegradation behavior forLLDPE/starch blends was monitored by soil burial test. The composted samples were recovered then washed followed by drying, and weighting samples after 30, 60, and 90 days to assess the change in weight loss. Also, mechanical properties including retention values of tensile strength and elongation at break were measured before and after composting. Furthermore, scanning electron microscope (SEM) was used to evaluate the change in the morphology of the polymeric blends. In addition to, the antimicrobial activity of plasticized LLDPE/starch blends films was evaluated using a standard plate counting technique.
Findings
The results illustrate that the water vapor transition rate increases from 2.5 g m−2 24 h−1 for LLDPE/5starch to 4.21 g m−2 24 h−1 and 4.43 g m−2 24 h−1 for castor and moringa oleifera respectively. Also, the retained tensile strength values of all blends decrease gradually with increasing composting period. Unplasticized LLDPE/5starch showed highest tensile strength retention of 91.6% compared to the other blends that were 89.61, 88.49 and 86.91 for the plasticized LLDPE/5starch with glycerol, castor and M. oleifera oils respectively. As well as, the presence of essential oils in LLDPE/ starch blends increase the inhibition growth of escherichia coli, candida albicans and staphylococcus aureus.
Originality/value
The objective of this work is to develop cost-effective and environmentally-friendly methods for preparing biodegradable polymers suitable for packaging applications.

Abstract
Purpose
This study aims to evaluate the nutrient content and acceptable qualities of plant-based burger patties (PBBP) formulated with chickpea flour, defatted sesame cake (DSC) flour, coffee silver skin and pomegranate juice as colorant.
Design/methodology/approach
The chemical composition, energy value, cholesterol content, amino acid composition, cooking loss, pH, color characteristics and sensory attributes of PBBP were analyzed using official procedures and compared to beef burger.
Findings
PBBP had a protein value of 16.0 g/100g, which is nearly close to the protein content of the beef burger (18.1 g/100g). The fat content of the PBBP was approximately three times lower than that of the beef burger. The fiber content in PBBP was approximately 23 times as high as that in beef burgers samples (p = 0.05). The raw PBBP samples supplies 178 Kcal/100g, whereas beef burger possessed 259 Kcal/100g. Neither the raw nor the cooked PBBP samples contained any cholesterol. Both the beef and PBBP displayed acceptability scores higher than 7.0, which suggests that PBBP was well accepted.
Originality/value
It is concluded that the PBBP sample exhibited a protein value of 16.0 g/100g, which is comparable to the protein level of beef burgers (18.1 g/100g). The fat level of the PBBP samples was significantly lower than that of the beef burger samples. Uncooked PBBP samples contained significantly higher fiber content compared to beef burger samples. No cholesterol was found in raw or cooked PBBP samples. Overall acceptance scores for both beef and PBBP samples exceeded 7.0, suggesting that the proposed product (PBBP) was received favorably.

Abstract
Purpose
Due to the increase in the prevalence of other risk factors of heart diseases, the age of heart disease has decreased and it has led to premature heart disease. One of the main risk factors of this disease is metabolic syndrome (MetS). One of the key ways to control MetS is dietary modification. The purpose of this study is to investigate the relationship between dietary patterns and MetS in patients with premature heart disease.
Design/methodology/approach
This study was conducted on 409 people with premature heart disease. The diagnosis of MetS was made based on the ATP III criteria. Dietary intake for the past year was collected using the validated semi-quantitative food frequency questionnaire. Dietary patterns were determined by factor analysis with principal components approach.
Findings
Three dietary patterns were identified, including the healthy, western and traditional patterns. The findings showed that people who followed the traditional pattern more than those who followed less had a lower risk of MetS. (OR:0.23; 95% CI: 0.11–0.52). But, no relation was observed between healthy (OR:1.45; 95% CI:0.64–3.25) and western (OR:1.04; 95% CI:0.51–2.13) patterns with MetS.
Originality/value
The findings of this study showed that following a traditional dietary pattern based on high consumption of whole grains, red meat, viscera, fish, eggs, high-fat dairy products, soft drinks, mayonnaise and solid oil was associated with a lower risk of MetS.

Abstract
Purpose
This paper aims to examine the association between the dietary inflammatory index, the consumption of Enteral Nutrition Supplemented with probiotics with certain serum inflammation markers and gastrointestinal complications among individuals diagnosed with COVID-19.
Design/methodology/approach
This cross-sectional investigation involved 100 COVID-19 patients who were admitted to intensive care units in hospitals. These patients were administered two different types of Enteral Nutrition, so the dietary inflammatory index (DII), gastrointestinal complications and some serum inflammation markers have been compared between two groups.
Findings
The mean DII scores in all patients were significantly pro-inflammatory (probiotic formula 2.81 ± 0.01 vs usual formula group 2.93 ± 0.14 p = 0.19). The probiotic formula consumption had an inverse association with High-sensitivity C-reactive Protein concentration (coef = −3.19, 95% CI −1.25, −5.14 p = 0.001) and lead to a reduction of 2.14 mm/h in the serum level of Erythrocyte sedimentation rate compared to normal formula. The incidence of diarrhea, abdominal pain and vomiting in probiotic formula patients was respectively 94%, 14% and 86% less than in usual formula patients (p = 0.05).
Originality/value
In this cross-sectional study for the first time, the authors found that probiotic formula consumption was inversely associated with serum inflammation markers and gastrointestinal complications incidence. The high DII leads to more gastrointestinal complications incidence and inflammation markers. More studies are needed to prove this relationship.

Abstract
Purpose
The purpose of this study was to evaluate the effects of the addition of flaxseed and amaranth at different proportions on the hydration kinetics, colour and sensory qualities of instant-extruded cereals, important aspects related to the functionality and acceptability of food products.
Design/methodology/approach
Instant-extruded cereals were made with different proportions of flaxseed (6.6–9.3%), amaranth (18.7–33.1%), and maize grits (63.8–67.3%); and characteristics such as hydration kinetics, colour parameters and sensory properties were evaluated.
Findings
The kinetics of milk absorption showed that the extruded cereals maintained their texture and crispness for a sufficiently long time (≤20 min). The L*, a* and chroma* values of the extruded cereals were significantly affected (p < 0.05) by the flaxseed content. Sensory evaluation showed that all the extrudates had good acceptance in terms of flavour, texture, and colour attributes in relation to high-fibre commercial cereals; according to the preference test, they were as acceptable as commercial extruded cereals when consumed with milk. The addition of high-fibre and protein-containing grains such as flaxseed (8.6–9.3%) and amaranth (18.7–22.9%) in instant-extruded cereals allowed the production of products with acceptable physical and sensory characteristics.
Originality/value
In this study a novel instant-extruded cereal with flaxseed and amaranth was developed. The evaluation of the physical and sensory characteristics of instant-extruded cereals is essential to guarantee consumer acceptability, especially if functional ingredients with a high content of dietary fibre and protein are added.

Abstract
Purpose
Bisphenol A (BPA) is a compound commonly used in the production of plastic bottles and containers, where it is used as a plasticizer and can migrate into food. Its intake may impair the functioning of endocrine glands and have a negative impact on the health of human, especially infants. Because it is also found in baby bottles. Generally BPA can enter the body through daily, cumulative and long-term consumption of various foods. The purpose of this study is to investigate the level of BPA and its migration through some food containers and bottles. It also explains the potential risks associated with its consumption.
Design/methodology/approach
In this study, some of the research conducted in this field has been used by searching in various Web databases, including ScienceDirect, Scopus and PubMed. Therefore, this study provides an overview of the migration of BPA from different packages and compares the obtained values with standard ranges.
Findings
Most studies showed samples below the reference value. However, the use of containers made with BPA should be controlled and government policies should be implemented to eliminate or reduce the use of these containers.
Originality/value
This paper collects evidence of migration of BPA to some foods through bottles and food containers.

This study aims to reveal the tribological mechanism of synergistic effect between MoDTC and P-containing additives in aluminum-based grease.
Abstract
Purpose
This study aims to reveal the tribological mechanism of synergistic effect between MoDTC and P-containing additives in aluminum-based grease.
Design/methodology/approach
The authors prepared a molybdenum dialkyl dithiocarbamate (MoDTC) and revealed the tribological mechanism of synergistic effect between MoDTC and P-containing additives in aluminum-based grease by combining with ZDDP and P-containing and S-free additives.
Findings
The MoDTC the authors prepared has good friction-reducing and anti-wear properties in aluminum-based grease and has an obvious synergistic effect with ZDDP. MoDTC and ZDDP have a significant synergistic effect on the tribological properties in aluminum-based grease, mainly because of the formation of phosphates and metaphosphates as well as more MoS2 in the friction film. P element plays a facilitating role in the chemical conversion of MoDTC to MoS2.
Originality/value
The experiments of MoDTC with tributyl phosphate and trimethylphenyl phosphate confirm that the P element plays a facilitating role in the chemical conversion of MoDTC into MoS2.

Abstract
Purpose
Schools have long been perceived as an ideal setting to support the healthy eating behaviours of children. The aim of the study was to examine the views of Australian primary school parents regarding school food and nutrition, including education, practices and policy.
Design/methodology/approach
An online survey was conducted among 787 parents in March 2021, which included closed and open-ended questions.
Findings
The results indicated the inconsistent implementation of policies and/or varying practices among different schools. Parents’ views were slightly associated with some demographic and personal measures including their SES levels, education, age, the main language spoken at home and universalism values. Parents viewed healthy food provision through canteens, policies and informing parents, fruit and vegetable breaks and kitchen and garden programs as the main contributors to the promotion of healthy eating. They believed unhealthy options in canteens, school fairs, events and birthdays are the major contributors to the formation of unhealthy eating habits among children at schools. Results revealed the efforts to establish health promoting school food environments in Australian primary schools; however, inconsistencies and discrepancies among schools should be addressed to ensure equity among all children.
Practical implications
The findings may provide directions for policymakers and school managers and can inform future reforms and initiatives in Australian primary schools and elsewhere.
Originality/value
This is the first study that has examined Australian parents’ views of school food policy, practices and environments using a mixed-methods design.
