Oleogelation of sunflower-linseed oils with carnauba wax as an innovative strategy for shortening substitution in cakes.

The aim of this study was to fabricate a carnauba wax oleogel with improved nutritional characteristics including reduced ω6:ω3 ratio and heightened alpha-linolenic acid through sunflower (SO): linseed oil (LO) in various ratios (100:0, 80:20, 70:30, 50:50, 30:70, 20:80, and 0:100 %), for potential shortening substitution in cakes. Combining LO with SO up to 50 % improved oleogel properties considering intra- or intermolecular hydrogen bonding and crystallinity. These oleogels had similar thermal behavior and better morphological structure than oleogel prepared exclusively with SO (100 SO), with reasonable oil binding capacity and oxidation stability.

Carnauba wax and adipic acid oleogels as an innovative strategy for cocoa butter alternatives in chocolate spreads.

The aim of this study was to replace cocoa butter substitute (CBS) with structured sunflower oil in chocolate spread partially. Two types of oleogel, 6% carnauba wax (CWO) and 2% carnauba wax with 4% adipic acid (AD-CWO) were substituted (at 20%, 50%, and 70%), and chocolate spread characteristics were evaluated. Various properties of chocolate spread samples were investigated as peroxide value, firmness, oil binding capacity, moisture content, molecular interactions, and molecular conformation of fat crystals.

Using maltitol and xylitol as alternative bulking agents in milk chocolate: modelling approach.

Unlabelled: The aim of the present study was to evaluate optimal concentration of polyols (maltitol and xylitol) by applying mixture design for the formulation of milk chocolate. The influences of polyols as sucrose substitutes on the main physicochemical parameters and sensory perception were determined. The optimization of the variables demonstrated that utilizing 85.

Chocolate flow behavior: Composition and process effects.

Chocolate is a non-Newtonian substance, and such substance has different viscosities at different shear rates. Rheological evaluations have become indispensable instruments for characterizing final chocolate, forecasting product efficiency and consumer acceptance. During production, the different steps depend on a well-defined viscosity and yield stress.

Carob powder as cocoa substitute in milk and dark compound chocolate formulation.

In the current research, the possibility of using carob powder as a substitute for cocoa powder in milk and dark compound chocolates was investigated. Five chocolate samples containing carob powder (20, 40, 60, 80 and 100%) along with control were produced and the physico-chemical analyzes were measured. Chocolate samples were assessed for sensory acceptance by a hedonic scale.

Optimization of prebiotic sucrose-free milk chocolate formulation by mixture design.

The purpose of the current research was to determine optimal situation by applying Simplex lattice mixture design for the formulation of prebiotic sucrose-free milk chocolate. Chocolate samples were prepared using two different sugar alcohols containing xylitol and maltitol along with galactooligosaccharide as prebiotic substance. The effects of sugar alcohols and prebiotic blends on rheological attributes and some physical characteristics were assessed.

Pre-crystallization process in chocolate: Mechanism, importance and novel aspects.

Pre-crystallization is an important step in the production of chocolate, which is defined as tempering of cocoa butter through primary and secondary nucleation. The goal of tempering is to obtain a sufficient amount of β polymorph of the right size. The pre-crystallization process has a great impact on the quality and production cost of final product.

Effects of polyols on the quality characteristics of sucrose-free milk chocolate produced in a ball mill.

Sucrose-free milk chocolates containing different types of bulk (isomalt, xylitol and maltitol) and high intensity (Stevia) sweeteners were produced by using a ball mill. The main quality characteristics of the formulated chocolates were evaluated and compared with those of the conventional sample containing sucrose. The Casson model was the best fitting model for the rheological data.

Formulation of dark chocolate as a carrier to deliver eicosapentaenoic and docosahexaenoic acids: Effects on product quality.

In this study, dark chocolate enriched with EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) was developed using various forms and origins. Quality characteristics such as physical, thermo-gravimetric, rheological, textural and sensory properties of chocolates were investigated. The highest EPA/DHA stability was determined in samples prepared by free-flowing powder and microencapsulated forms of omega-3 fatty acids (FA).
