Isolation and survival of Yersinia enterocolitica in ice cream at different pH values, stored at -18°c BJM
Pederiva,Norma B. Barbini de; Guzmán,Ana M. Stefanini de.
The presence of Yersinia enterocolitica was investigated in 203 samples of industrial (123) and non-industrial ice cream (80). Two Y. enterocolitica strains were isolated from non-industrial ice cream, which suggests the possibility of post-manufacturing contamination. One strain was typed as B:1A, O: 3,50,51; lis Xz, while the other one was biotyped as: B:1A but not serologically typed. Survival of Y. enterocolitica was investigated by inoculating nine samples of industrially manufactured ice cream to contain 20 CFU/ml of Y. enterocolitica and stored at -18°C for 480 days. The inoculated samples were classified into three different groups according to their pH (Group 1: pH 4-5; Group 2: pH 5-6 and Group 3: pH 6-7). Viability was determined by a...

Characterization and evaluation of sensory acceptability of ice creams incorporated with beta-carotene encapsulated in solid lipid microparticles Ciênc. Tecnol. Aliment.
LIMA,Juliana Gobbi de; BRITO-OLIVEIRA,Thais Carvalho; PINHO,Samantha Cristina de.
Abstract The feasibility of incorporating beta-carotene-loaded solid lipid microparticles (BCSLM) into vanilla ice creams was investigated, through the physico-chemical characterization and evaluation of sensory acceptability of the products products. The BCSLM were produced with palm stearin as the lipid phase, hydrolyzed soy protein isolate as the surfactant, and xanthan gum as the thickener. The results showed similar values of proximate composition, total soluble solids, pH, and overrun for all formulations. On the other hand, colorimetric evaluations showed that the ice cream produced with partial substitution of artificial additives by BCSLM containing alpha-tocopherol presented a more intense color, while in the product with non-encapsulated...

Formulation of a peach ice cream as potential symbiotic food Ciênc. Tecnol. Aliment.
VILLALVA,Fernando Josué; CRAVERO BRUNERI,Andrea Paula; VINDEROLA,Gabriel; GONÇALVEZ DE OLIVEIRA,Enzo; PAZ,Noelia Fernanda; RAMÓN,Adriana Noemí.
Abstract Today’s population increasingly demands and consumes healthy products. For this reason, the food industry has been developing and marketing food with added bioactive components. The aim of this work was to formulate a peach ice cream reduced in calories with an added probiotic (Bifidobacterium lactis Bb-12) and prebiotics (inulin), and to evaluate its sensory quality and acceptability as potential symbiotic food. The moisture content was 76.47%; 7.14% protein; 0.15% fat; 6.37%; carbohydrates; 9.87% inulin; 1.22% ash; 0.201% calcium, 0.155% phosphorus and 0.168% sodium. On the first and 21th day of storage counts of B. lactis Bb – 12 was 4 x 108 CFU/mL and 1.5 x 107 CFU/mL, respectively. It was possible to formulate a peach ice cream reduced in...

Application of fats in some food products Ciênc. Tecnol. Aliment.
Rios,Raquel Vallerio; Pessanha,Meibel Durigan Ferreira; Almeida,Poliana Fernandes de; Viana,Clara Leonel; Lannes,Suzana Caetano da Silva.
Fats and oils are very important raw materials and functional ingredients for several food products such as confectionery, bakery, ice creams, emulsions, and sauces, shortenings, margarines, and other specially tailored products. Formulated products are made with just about every part of chemistry, but they are not simple chemicals. In general, they consist of several, and often many, components. Each of these components has a purpose. Most formulated products have a micro- or nano-structure that is important for their function, but obtaining this structure is often the big challenge. Due to a rise in overweight or obesity, health concerns have increased. This fact has led to the need to the develop products with low fat content, which have become a market...

Orange fiber as a novel fat replacer in lemon ice cream Ciênc. Tecnol. Aliment.
Crizel,Tainara de Moraes; Araujo,Rubilene Ramos de; Rios,Alessandro de Oliveira; Rech,Rosane; Flôres,Simone Hickmann.
Orange fiber was used as a novel fat replacer in light lemon ice cream. Nine ice cream formulations were compared: standard control ice cream (IC); ice cream with fiber (F1) from the peel, bagasse, and orange seed (ICA and ICB); ice cream with fiber (F2) from the orange peel alone (ICC and ICD); ice cream with fiber (F3) from the peel, bagasse, and orange seed pretreated with hydro-distillation (ICE and ICF); and ice cream with fiber (F4) from the orange peel pretreated with hydro-distillation (ICG and ICH).The orange fiber reduced the ice cream fat content (50 %) and the overrun ratio and increased the fiber content and the hardness, gumminess, and springiness values, but it did not affect the adhesiveness and odor of the samples. The samples with 1.0 %...

Different formulations of camu-camu popsicle: characterization, vitamin C and sensorial analysis of an opportunity to family agroindustry Ciênc. Tecnol. Aliment.
GRIGIO,Maria Luiza; DURIGAN,Maria Fernanda Berlingieri; CHAGAS,Edvan Alves.
Abstract The high levels of vitamin C in camu-camu have stimulated the interests of extractivists, farmers and consumers. The aim of this study was to characterize five accessible for family agroindustry different formulations of camu-camu popsicles and assess their acceptance. A completely randomized design was used and the treatments consisted of five different popsicle formulations: camu-camu pulp (T1 and T2: 27%, T3 and T4: 20.8%; T5: 61%), water (T1 and T2: 43.5%, T3 and T4: 20.8%; T5: no water), whole milk powder (T1 and T2: 14.7%, T3 and T4: 29.2%; T5: 18.3%), sugar (T1 and T2: 14.7%, T3 and T4: 29% and T5: 20.6%), neutral alloy and emulsifier. The formulations were processed and the popsicles were evaluated for pH, soluble solids, titratable...

Effect of different sweetener blends and fat types on ice cream properties Ciênc. Tecnol. Aliment.
Silva Junior,Elieste da; Lannes,Suzana Caetano da Silva.
The development of processed foods requires the understanding of the phenomena that dictate the ingredient interactions normally used in food formulations, as well as the effects of the numerous operations involved in the processing of the final product. In ice creams, sugars are responsible for taste, but they also affect the freezing behavior and viscosity of processed mixes. Components such as fats influence mechanical properties, melting resistance, and palatability of final products. The objective was to study the technological effects of different sugars and fats on the structure of ice cream formulations. Fructose syrup was used as a substitute for glucose syrup in blends with sucrose, and palm fat was employed as an alternative to hydrogenated...

Replacing sugar with S. rebaudiana extracts on the physicochemical and sensory properties of strawberry ice cream Ciência Rural
Aranda-Gonzalez,Irma; Perera-Pacheco,Maribel; Barbosa-Martín,Enrique; Betancur-Ancona,David.
ABSTRACT: Ice cream is a product whose formulation requires considerable amounts of sugar. In addition to providing flavor, sugar contributes to the physicochemical characteristics of ice cream but its consumption in large quantities is related to chronic diseases such as diabetes and obesity. For this reason, the food industry seeks to formulate products with sweeteners that preserve the physicochemical and sensory characteristics of the original product. Stevia rebaudiana is a plant that naturally contains glycosides with no calories and high sweetening capacity and it is considered safe for consumption. Therefore the aim of this research was to evaluate the effect of replacing sugar with different levels of extracts of S. rebaudiana Morita II and...

Censored Quantile Regression and Purchases of Ice Cream AgEcon
Gustavsen, Geir Waehler; Jolliffe, Dean; Rickertsen, Kyrre.
The effects on purchases of ice cream of increasing the value added tax (VAT) for less healthy foods and removing the VAT for healthy foods are estimated. The effects on high- and low-purchasing households are estimated by using quantile regressions. Many households did not purchase ice cream and censored quantile regressions are estimated by a recently developed algorithm, which is simple, robust, and performs well near the censoring point. High-purchasing households will reduce their annual per capita purchases with 1.8 kilograms corresponding to an annual reduction of more than half a kilogram of body weight.
