Application of power ultrasound to Food freezing is a relatively new subject, cavitations is the most significant power which can not only lead to the production of gas bubbles in ice ream but also the occurrence of micro streaming, also it can promote ice nucleation to accelerate the heat and mass transfer process accompanying the freeze process. In this work ice cream freezing process time af...

in this research, stevia and inulin was used as sugar and fat replacer in dietetic ice cream formulation, respectively. ice cream formulation with stevia (0-100%) and inulin (0-85%) was optimizedusing response surface methodology.dependent variables included specific gravity (sg), viscosity, overrun, first drop and melting. the results showed that sg had converse relation with replacing stevia ...

In the ice cream industry, the type of final desired product (large cartons (sqrounds) or ice creams on a stick) determine the viscosity at which the ice cream has to be produced. One of the objectives of the ice cream crystallization processes is therefore to produce an ice cream of specified viscosity. In this paper, a nonlinear control strategy is proposed for the control of the viscosity of...

This study was conducted to investigate the physical and sensory properties of ice cream containing fermented pepper powder. Three ice cream formulas were manufactured: 1, control; 2, supplemented with 0.1% fermented pepper powder; and 3, supplemented with 0.2% fermented pepper powder. Formulas 2 and 3 had significantly higher viscosity and lower overrun than formula 1 (p<0.05). Additionally, i...

The effect of the interaction of iota-carrageenan (ICG) or lambda-carrageenan (LCG) with locust bean gum and carboxymethylcellulose on the properties of ice cream was studied employing a mixture design approach. A model formulation was employed with of 5% (w / w) of hydrocolloids like stabilizers. Hydrocolloids mixture effect on ice cream properties (base viscosity, ice-cream overrun, hardness,...

BACKGROUND Yersinia species, especially Yersinia enterocolitica, are considered as the most prevalent milk-borne pathogens. Several serological and molecular techniques have been developed for rapid and safe diagnosis of yersiniosis. OBJECTIVES This study was carried out to assess the prevalence rate of Yersinia species, especially Y. enterocolitica, in milk and dairy products in Isfahan prov...

A study was performed to apply a probiotic strain into fermented ice cream mix with suitable fruit bases to develop a value-added product with a substantial level of viable organisms for a sufficient shelf life. Pure direct vat strain culture of Lactobacillus acidophilus (LA 5) in freeze-dried form was inoculated into a mixture of ice cream, frozen, and the number of viable organisms during fro...

current interests towards lowering fat content in food products and producing healthier and safer foods, have convinced ice cream manufacturers to substitute milk fat in ice cream with either carbohydrate or protein based fat replacers. in the present work, reduced-fat ice cream (5% fat) was produced using milk protein concentrate (65%) and inulin as fat replacers (0, 2 and 4%) as well as two t...

The development of a low glycemic index (GI) coconut milk ice cream by replacing 12% sucrose with different low GI sweeteners (xylitol, erythritol, inulin and fructose) was investigated. Three mixtures of sweeteners (6.2% xylitol + 7% inulin, 4% erythritol + 7% inulin + 2.15% fructose, 8.5% inulin + 5% fructose) were reformulated to obtain the similar characteristics as using 12% sucrose, inclu...

Probiotic ice cream was made by fermenting a standard ice cream mix with Lactobacillus acidophilus and Bifidobacterium bifidum cultures and then freezing the mix in a batch freezer. Survival of the L. acidophilus and B. bifidum, as well as beta-galactosidase activity, was monitored during 17 wk of frozen storage at -29 degrees C. After freezing of the fermented mix, bacterial counts were 1.5 x ...
