[Ti] Título: Using Ice Cream for Diagnosis of Diabetes Mellitus and Impaired Glucose Tolerance: An Alternative to the Oral Glucose Tolerance Test. [So] Source: Am J Med Sci;354(6):581-585, 2017 12. [Is] ISSN: 1538-2990 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: BACKGROUND: Oral glucose tolerance test (OGTT) is a sensitive and reliable test for diabetes mellitus and impaired glucose tolerance (IGT). However, poor patient tolerance of glucose solutions is common. We aim to compare the diagnostic value of an ice cream test with a standard OGTT. MATERIALS AND METHODS: A total of 104 healthy adults were randomly assigned to either 75-g OGTT or ice cream, followed by a crossover to the other test. RESULTS: Most patients were females (71%). Mean age was 37 ± 12 years, and body mass index was 24.2 ± 3.9kg/m . Diabetes mellitus and IGT, as diagnosed by 75-g OGTT, were 4.8% and 6.7%, respectively. The 2-hour plasma glucose levels were 110 ± 55.5mg/dL with 75-g glucose and 97.52 ± 40.7mg/dL with ice cream. The correlation coefficient of 2-hour plasma glucose for the 2 tests was 0.82 (95% CI: 0.75-0.87; P < 0.001). Discordant diagnostic results, based on 2-hour plasma glucose levels, were 9.61%. By using a combination of fasting plasma glucose and 2-hour plasma glucose values, the ice cream test would have missed 5.76% of those at high risk for diabetes mellitus (impaired fasting glucose and IGT) or diabetes. CONCLUSIONS: An ice cream test may serve as an alternative to a 75-g OGTT. Before applying this test in clinical practice, it needs to be validated in a larger population.

[Is] ISSN: 0308-8146 [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: The following strains of bacteria: Lactobacillus rhamnosus B 442, Lactobacillus rhamnosus 1937, and Lactococcus lactis JBB 500 were enriched with magnesium ions using Pulsed Electric Fields. The potentially probiotic strains were added to the mixture in the DVS process and applied for the production of ice cream which were then analyzed physicochemically and microbiologically. Results showed that addition of bacteria enriched with magnesium did not change chemical parameters of the ice cream and did not affect the freezing process, meltability, and hardness. No significant differences were noted in colour of the samples. The ice cream with addition of bacteria enriched with magnesium had higher adhesiveness. The results of viability determination showed that the total number of microorganisms in the ice cream was higher than in the starter cultures. Viability of the bacteria enriched with magnesium in the obtained ice cream was lower in comparison to the control samples.

[Ti] Título: Heavy Metal Presence in Two Different Types of Ice Cream: Artisanal Ice Cream (Italian Gelato) and Industrial Ice Cream. [So] Source: J Food Prot;80(3):443-446, 2017 Mar. [Is] ISSN: 1944-9097 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: Ice cream, a popular product worldwide, is usually a milk-based product with other types of ingredients (fruit, eggs, cocoa, dried fruit, additives, and others). Different materials are used to obtain the desired taste, texture, consistency, and appearance of the final product. This study surveyed ice cream products available in Italy for heavy metals (lead, cadmium, chromium, tin, and arsenic). The differences between artisanal and industrial ice cream were also investigated because of the importance in the Italian diet and the diffusion of this ready-to-eat food. Ice cream sampling was performed between October 2010 and February 2011 in the northeast of Italy. A total of 100 samples were randomly collected from different sources: 50 industrial samples produced by 19 different brands were collected in coffee bars and supermarkets; 50 artisanal ice cream samples were gathered at nine different artisanal ice cream shops. Ten wooden sticks of industrial ice cream were analyzed in parallel to the ice cream. All samples were negative for arsenic and mercury. None of the artisanal ice cream samples were positive for lead and tin; 18% of the industrial ice cream samples were positive. All positive lead samples were higher than the legal limit stated for milk (0.02 mg/kg). All industrial ice cream samples were negative for cadmium, but cadmium was present in 10% of the artisanal ice cream samples. Chromium was found in 26% of the artisanal and in 58% of the industrial ice cream samples. The heavy metals found in the wooden sticks were different from the corresponding ice cream, pointing out the lack of cross-contamination between the products. Considering the results and the amount of ice cream consumed during the year, contamination through ice cream is a low risk for the Italian population, even though there is need for further analysis.

[Ti] Título: Omega-3 fatty acids and oxidative stability of ice cream supplemented with olein fraction of chia (Salvia hispanica L.) oil. [So] Source: Lipids Health Dis;16(1):34, 2017 Feb 07. [Is] ISSN: 1476-511X [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: BACKGROUND: Chia (Salvia hispanica L.) has been regarded as good source of polyunsaturated omega-3 fatty acids with cardiac, hepatic, hypotensive, antiallergic and antidiabetic role. Concentration of omega-3 fatty acids in chia oil can be enhanced by fractionation. Olein/low melting fraction of chia oil has higher concentration of omega-3 fatty acids. Therefore, main objective of current investigation was determination of various concentration effect of olein fraction of chia oil on omega-3 fatty acids, oxidative stability and sensory characteristics of ice cream. METHODS: Ice cream samples were prepared by partially replacing the milk fat with olein fraction of chia oil at 5, 10, 15 and 20% concentrations (T , T , T and T ), respectively. Ice cream prepared from 100% milk fat was kept as control. Ice cream samples stored at -18 °C for 60 days were analysed at 0, 30 and 60 days of the storage period. Fatty acid profile, total phenolic contents, total flavonoids, free fatty acids, peroxide value, anisidine value and sensory characteristics of ice cream samples was studied. RESULTS: Concentration of α-linolenic acid, eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid in T was 13.24, 0.58, 0.42 and 0.31%, respectively. Total phenolic contents of control, T , T , T and T were recorded 0.12, 1.65, 3.17, 5.19 and 7.48 mg GAE/mL, respectively. Total flavonoid content of control, T , T , T and T were found 0.08, 0.64, 1.87, 3.16 and 4.29 mg Quercetin Equivalent/mL. 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity of control, T , T , T and T was noted 5.61, 17.43, 36.84, 51.17 and 74.91%, respectively. After 60 days of storage period, the highest peroxide value of 1.84 (MeqO /kg) was observed in T , which was much less than allowable limit of 10 (MeqO /kg). Flavour score was non-significant after 30 days of storage period. CONCLUSIONS: Supplementation of ice cream with olein fraction of chia oil enhanced the concentration of omega-3 fatty acids and improved the antioxidant perspectives of ice cream. These results suggest that omega-3 fatty acids and antioxidant characteristics of ice cream may be improved with olein fraction of chia oil for discerning consumers.

[Ti] Título: Assessing the genome level diversity of Listeria monocytogenes from contaminated ice cream and environmental samples linked to a listeriosis outbreak in the United States. [So] Source: PLoS One;12(2):e0171389, 2017. [Is] ISSN: 1932-6203 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: A listeriosis outbreak in the United States implicated contaminated ice cream produced by one company, which operated 3 facilities. We performed single nucleotide polymorphism (SNP)-based whole genome sequencing (WGS) analysis on Listeria monocytogenes from food, environmental and clinical sources, identifying two clusters and a single branch, belonging to PCR serogroup IIb and genetic lineage I. WGS Cluster I, representing one outbreak strain, contained 82 food and environmental isolates from Facility I and 4 clinical isolates. These isolates differed by up to 29 SNPs, exhibited 9 pulsed-field gel electrophoresis (PFGE) profiles and multilocus sequence typing (MLST) sequence type (ST) 5 of clonal complex 5 (CC5). WGS Cluster II contained 51 food and environmental isolates from Facility II, 4 food isolates from Facility I and 5 clinical isolates. Among them the isolates from Facility II and clinical isolates formed a clade and represented another outbreak strain. Isolates in this clade differed by up to 29 SNPs, exhibited 3 PFGE profiles and ST5. The only isolate collected from Facility III belonged to singleton ST489, which was in a single branch separate from Clusters I and II, and was not associated with the outbreak. WGS analyses clustered together outbreak-associated isolates exhibiting multiple PFGE profiles, while differentiating them from epidemiologically unrelated isolates that exhibited outbreak PFGE profiles. The complete genome of a Cluster I isolate allowed the identification and analyses of putative prophages, revealing that Cluster I isolates differed by the gain or loss of three putative prophages, causing the banding pattern differences among all 3 AscI-PFGE profiles observed in Cluster I isolates. WGS data suggested that certain ice cream varieties and/or production lines might have contamination sources unique to them. The SNP-based analysis was able to distinguish CC5 as a group from non-CC5 isolates and differentiate among CC5 isolates from different outbreaks/incidents.

[Ti] Título: Synbiotic Amazonian palm berry (açai, Euterpe oleracea Mart.) ice cream improved Lactobacillus rhamnosus GG survival to simulated gastrointestinal stress. [So] Source: Food Funct;8(2):731-740, 2017 Feb 22. [Is] ISSN: 2042-650X [Cp] País de publicação: England [La] Idioma: eng [Ab] Resumo: The effect of açai pulp ice cream and of its supplementation with inulin (I), whey protein concentrate (WC), and/or whey protein isolate (WI) on the viability and resistance to simulated gastrointestinal stress of the probiotic Lactobacillus (Lb.) rhamnosus GG strain throughout storage at -18 °C for up to 112 days was evaluated and morphological changes during stress were monitored. Lb. rhamnosus GG viability was stable in all formulations for up to 112 days of storage, preserving populations around 9 log CFU g . Compared to the fresh culture, Lb. rhamnosus GG showed higher survival under simulated gastrointestinal conditions when incorporated into açai ice cream, indicating that the presence of the food matrix contributed to the microorganism survival. A reduction of at least 5 log cycles of Lb. rhamnosus GG was observed in all formulations after the gastrointestinal simulation in all storage periods assessed. The addition of I, WC, and/or WI did not show any significant effect on the probiotic survival under simulated gastrointestinal stress (p < 0.05). Compared to the fresh culture, fewer morphological changes were observed when the probiotic was added to ice cream. Thus, the açai pulp ice cream was shown to be a suitable matrix for Lb. rhamnosus GG, improving its survival under in vitro simulated gastrointestinal conditions.

[Ti] Título: Comparative evaluation of direct plating and most probable number for enumeration of low levels of Listeria monocytogenes in naturally contaminated ice cream products. [So] Source: Int J Food Microbiol;241:15-22, 2017 Jan 16. [Is] ISSN: 1879-3460 [Cp] País de publicação: Netherlands [La] Idioma: eng [Ab] Resumo: A precise and accurate method for enumeration of low level of Listeria monocytogenes in foods is critical to a variety of studies. In this study, paired comparison of most probable number (MPN) and direct plating enumeration of L. monocytogenes was conducted on a total of 1730 outbreak-associated ice cream samples that were naturally contaminated with low level of L. monocytogenes. MPN was performed on all 1730 samples. Direct plating was performed on all samples using the RAPID'L.mono (RLM) agar (1600 samples) and agar Listeria Ottaviani and Agosti (ALOA; 130 samples). Probabilistic analysis with Bayesian inference model was used to compare paired direct plating and MPN estimates of L. monocytogenes in ice cream samples because assumptions implicit in ordinary least squares (OLS) linear regression analyses were not met for such a comparison. The probabilistic analysis revealed good agreement between the MPN and direct plating estimates, and this agreement showed that the MPN schemes and direct plating schemes using ALOA or RLM evaluated in the present study were suitable for enumerating low levels of L. monocytogenes in these ice cream samples. The statistical analysis further revealed that OLS linear regression analyses of direct plating and MPN data did introduce bias that incorrectly characterized systematic differences between estimates from the two methods.

[Ti] Título: Natural antioxidant ice cream acutely reduces oxidative stress and improves vascular function and physical performance in healthy individuals. [So] Source: Nutrition;33:225-233, 2017 Jan. [Is] ISSN: 1873-1244 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: OBJECTIVE: The formation of reactive oxygen species (ROS) contributes to the pathogenesis and progression of several diseases. Polyphenols have been shown to be beneficial against ROS. The aim of this study was to evaluate the effects of a natural antioxidant ice cream on oxidative stress, vascular function, and physical performance. METHODS: In this controlled, single-blind, crossover study, 14 healthy individuals were randomized to consume 100 g of either antioxidant ice cream containing dark cocoa powder and hazelnut and green tea extracts or milk chocolate ice cream (control ice cream). Participants were studied at baseline and 2 h after ingesting ice cream. Serum polyphenols, antioxidant status (ferric-reducing ability of plasma [FRAP]), nitric oxide (NOx) bioavailability, markers of oxidative stress (determination of reactive oxygen metabolites [d-ROMs] and hydrogen peroxide [H O ]), endothelium function (flow-mediated dilation [FMD] and reactive hyperemia index [RHI]), and exercise tolerance (stress test) were assessed, and the double product was measured. RESULTS: Serum polyphenols (P < 0.001), NOx (P < 0.001), FRAP (P < 0.005), FMD (P < 0.001), and RHI (P < 0.05) increased significantly, oxidative stress decreased (d-Roms, P < 0.001; H O , P < 0.001), and the double product (P < 0.001) was improved only after antioxidant ice cream ingestion. No changes were found after control ice cream ingestion. CONCLUSIONS: To our knowledge, this is the first study to demonstrate that a natural ice cream rich in polyphenols acutely improved vascular function and physical performance in healthy individuals through a reduction in oxidative stress.

[Is] ISSN: 1944-9097 [Cp] País de publicação: United States [La] Idioma: eng [Ab] Resumo: A most-probable-number (MPN) method was used to enumerate Listeria monocytogenes in 2,320 commercial ice cream scoops manufactured on a production line that was implicated in a 2015 listeriosis outbreak in the United States. The analyzed samples were collected from seven lots produced in November 2014, December 2014, January 2015, and March 2015. L. monocytogenes was detected in 99% (2,307 of 2,320) of the tested samples (lower limit of detection, 0.03 MPN/g), 92% of which were contaminated at <20 MPN/g. The levels of L. monocytogenes in these samples had a geometric mean per lot of 0.15 to 7.1 MPN/g. The prevalence and enumeration data from an unprecedented large number of naturally contaminated ice cream products linked to a listeriosis outbreak provided a unique data set for further understanding the risk associated with L. monocytogenes contamination for highly susceptible populations.

[Ti] Título: Properties of ice-cream fortified with zinc and Lactobacillus casei. [So] Source: Acta Sci Pol Technol Aliment;15(4):367-377, 2016 Oct-Dec. [Is] ISSN: 1898-9594 [Cp] País de publicação: Poland [La] Idioma: eng [Ab] Resumo: BACKGROUND: In this study, the possible effects of zinc on physicochemical properties of ice cream and the survival of Lactobacillus casei during a 90 days storage at -18°C was investigated. METHODS: Samples were divided into four experimental groups as follows: control, zinc fortified ice cream, probiotic ice cream, zinc fortified and probiotic ice cream. The physicochemical, texture, organoleptic properties and the survival of probiotics, were investigated. RESULTS: Results showed that the addition of zinc did not affect the textural properties of ice creams. Viscosity and pH were independently decreased in all groups in the presence of zinc. A significant increase in the lipid oxidation rate especially in the zinc fortified group was also observed. The probiotic counts were maintained above the least advised quantities (106 cfu/g) which were subsequently reduced following the three months of storage. In the zinc fortified samples, the counts were higher compared to the other groups with no zinc addition. The addition of probiotics and zinc had no significant effect on the sensory properties of ice cream. CONCLUSIONS: As a final conclusion, the commercial production of zinc fortified ice cream is recommended.
