The Influence of Oat β-Glucans of Different Molar Mass on the Properties of Gluten-Free Bread.

The influence of β-glucans on the properties of gluten-free dough and bread is still not fully explained, with the literature suggesting both positive and negative effects. The aim of this study was to investigate the effect of the molar mass of oat β-glucans on the properties of gluten-free bread. Gluten-free breads were baked under standardized conditions from a model gluten-free mix without and with a 1% or 2% share of oat β-glucans of a low molar mass of 24,540 g/mol, a medium molar mass of 85,940 g/mol and a high molar mass of 1,714,770 g/mol. The share of β-glucans affected the increase in water addition to the baking mix and dough yield proportionally to the molar mass and amount of β-glucans. The β-glucans of the highest molar mass, particularly at a 2% share, were most effective in increasing bread volume, reducing hardness and increasing the moisture content of the bread crumb on the day of baking, as well as reducing the increase in hardness and maintaining a high moisture content of the bread crumb after 1 day of storage, compared to bread without added β-glucans.

Nutritional Quality of Gluten-Free Bakery Products Labeled Ketogenic and/or Low-Carb Sold in the Global Market.

Gluten-free and ketogenic bakery products are gaining momentum. This study aims to develop a better understanding of the nutritional quality of gluten-free bakery products labeled ketogenic and/or low-carb. For this reason, the products available on the global market that were labeled ketogenic and/or low-carb (n = 757) were retrieved and compared to standard gluten-free products (n = 509). Overall, nutritionally, no significant differences were found among ketogenic and/or low-carb products due the high intra-variability of each type, but they differed from standard products. Compared to standard products, all ketogenic and/or low carb, irrespective of categories, showed lower carbohydrates that derived chiefly from fibers and, to a lesser extent, from sugars. They also had higher protein contents (p < 0.05) compared to standard products. Fats was higher (p < 0.05) in ketogenic and/or low-carb baking mixes, savory biscuits, and sweet biscuits than in their standard counterparts. Saturated fats were higher (p < 0.05) in low-carb savory biscuits and breads, as well as in ketogenic sweet biscuits than in the same standard products. Overall, median values of the nutrients align with the definition of the ketogenic diet. Nevertheless, several products did not align with any of the ketogenic definitions. Therefore, consumers need to carefully read the nutritional facts and not rely on mentions such as low-cab and ketogenic to make their decision of purchase/consumption.

Evaluation of Flour Safety Messages on Commercially Available Packages: An Eye-Tracking Study.

Wheat flour and baking mix have been associated with foodborne outbreaks and recalls, yet many consumers are unaware of the repercussions of consuming raw flour products. The objective of this study was to evaluate the accessibility of flour safety messages on commercially available packages and to identify consumer barriers to processing these messages. Eye-tracking technology was used to track the eye movements of 47 participants to assess their time to fixation (TTF) on the flour safety messages on 10 commercial packages. Notifications that were longer than one sentence were considered “long” messages, while notifications that consisted of only one sentence were considered short (S1–S5 and L1–L5). Only two participants (4.3%) found messages on all 10 packages. Highly accessible messages did not result in a high preference of presentation among participants. Most of the participants (98%) found the message on the S4 package, which correlated with the lowest TTF of 7.08 s. However, only 15% of those who found the S4 message chose it as their preferred message. Many participants who were interviewed said that they preferred messages that identified the reasoning for the warnings. They also preferred the messages that were well separated from other content on the package. Flour safety messages on the current packages are not effective to convey information and change consumer behavior. More science-based messaging strategies need to be developed to provide guidance for flour safety communication.

Development of a functional bread technology based on a grain baking mixture

One of the priority areas for developing the food industry is to increase the production of functional food products. When developing the latter, fruit and berry processing products, grain baking mixes are used. At the same time, there are no baking mixes with the use of bioactivated wheat, characterized by an increased content of macro- and micronutrients, antioxidants, and a reduced amount of phytin. However, the preparation of grain bread based on a baking mixture of bioactivated wheat crushed by the disintegration wave method with a moisture content of 10.0 ± 0.5 % led to the production of products with a sticky, strongly jamming crumb. The aim of the research was to develop a baking mixture of bioactivated wheat and functional grain bread of improved quality based on it. At the first stage of the research, the composition of the baking mixture based on bioactivated wheat grain was selected to obtain the best quality product, at the second stage, the chemical composition of bread was evaluated based on the developed baking mixture. The change in the properties of the dough during fermentation, the quality indicators of bread after 20 hours of storage and its chemical composition were evaluated in accordance with the methods specified in the current standards. The best properties of the dough and the quality of the bread have been observed in a sample obtained on the basis of a baking mixture, in 100 g of which 75 % of the grain products are dry bioactivated wheat crushed by the disintergation-wave method, and 25 % - baking wheat flour of the first grade. As a result of the assessment of the chemical composition of the developed product, it has been found that it belongs to functional food products. The preparation of grain bread using this technology will also allow us to solve one of the tasks of the state policy in the field of healthy nutrition aimed at increasing the production of functional products.

Current Situation with the Sensory Quality of Gluten-Free Bakery Products from the Czech Market Network

Abstract A large number of gluten-free baking mixes for making homemade bakery products can be found on the market, in addition to ready-made products – both unpacked and packed. The main objective of this study was to examine the current situation regarding the sensory quality of commercially available gluten-free bakery products on the Czech market. In total, 16 samples were analysed both individually and within groups of unpacked bakery products, packed bakery products, and bakery products made in a technological laboratory using baking mixes. Both a quantitative descriptive analysis and hedonic test of gluten-free bakery products were performed by 18 trained panellists, consisting of academic staff and students of University of Veterinary Sciences Brno, Czech Republic. The results were statistically evaluated by means of principal component analysis. A close correlation between descriptors of surface colour, saltiness, and overall pleasantness of the sample was established. Descriptors of surface colour (1.36–5.75), saltiness (1.22–4.12), sweetness (1.78–5.08), and yeastiness (1.93–4.52) showed the highest degree of variability in the evaluation of individual samples. Statistically highly significant differences were observed between the individual groups of samples of gluten-free bakery products. Based on hedonic testing, the group comprising samples of unpacked bakery products was evaluated as the best; in contrast, the group comprising packed bakery products was evaluated as the worst. The group comprising samples baked from purchased baking mixes was characterized by statistically significantly lower pleasantness of appearance and taste.

Разработка смесительного агрегата для получения мучных хлебопекарных смесей с повышенным содержанием белка

Introduction. Semi-finished products help food industry enterprises to meet the population’s need for high-quality and nutritious foods. Popular semi-products are loose mixes enriched with vitamins, minerals, and biologically active substances. The world is currently experiencing a shortage of food protein, and its deficiency is likely to continue in the coming decades. Therefore, loose high-protein baking mixes are one of the promising directions of healthy nutrition industry. Multicomponency of such mixes makes it possible to balance their composition and develop products that have a useful comprehensive effect on the human body and strengthen protective functions.
 Study objects and methods. In order to ensure a balanced composition of mixes and high-quality food production, the authors propose a new design of a continuous action vibration mixer. Experimental and industrial tests were carried out as part of a technological line for production of baking mixes with increased protein content. Trials included idling and serviceability check under load, quality tests of the obtained high-protein baking mix, as well as vibration and noise level tests.

The biological value of the finished food product showed a higher nutritional value than in the control sample.
 Conclusions. The new vibration type mixing unit made it possible to obtain baking mixes of specified quality at the ratio of mixed components 1:60. This simple but reliable device had relatively low material and energy costs.

Определение ключевых параметров работы вибрационного смесителя при получении мучных хлебопекарных смесей

Food is one of the major health-determining factors. Thus, any product should be of high quality and contain valuable substances. Therefore, the authors selected a flour baking mix with a high content of protein to determine the key operation parameters of the vibration mixer. There have been a lot of researches that feature flour baking mixes with the help of various mixers. The present research employed an original vibration mixer of continuous action with a method of “consecutive dilution”. The experiment determined the speed of vibrotransportation of the protein mix through the operating part of the device. The power consumption of the device, as well as the speed of the vibrotransportation of the baking mix, can affect the process of mixing. Therefore, the authors studied the mutual impact of the technological parameters of the mixer and the power consumption. The analysis helped to determine the effect of the key parameters on the speed of vibrotransportation of the flour baking mix. The speed υ increased with the increase in the oscillation frequency of the operating part f and the vibration amplitude A. A high amplitude and oscillation frequency proved to increase the value of power consumption of the vibromixer. Its key operation parameters were as follows: the amplitude of vibration A = 0.0035 m, the angle of vibration β = 45°, the height of the vibroboiling layer = 0.02 m, the diameter of perforation of the operating part of the device d = 0.007 m.

The use of a continuous-action centrifugal-screw mixer for improving the quality of flour baking mixes for functional purposes

The influence of the number of screw turns of a centrifugal-screw mixer, the number of holes in the screw turns and the rotor speed on the quality of mixing of flour baking mixes of functional purpose enriched with amino acids was studied. Flour baking mix is composed of wheat flour, whole wheat flour, chickpeas flour, rye flour, buckwheat flour, oat bran, gluten, dry milk powder, sesame seeds, flax seed, dried onions, table salt and sugar. The homogeneity of the mixture reflects table salt because it has a minimal weight relative to other components of the mix. The coefficient of heterogeneity was calculated to assess the quality of mixing. The centrifugal-screw mixer optimal operation parameters were investigated for different flour baking mixes. For the mix № 1 and mix № 2 optimal parameters are rotor rotating speed of 900 rpm, the number of turns of the screw 4 and the number of holes on the threads of the screw 4. For the mix № 3 optimal parameters are rotor speed of 500 rpm, the number of turns of the screw 2 and the number of holes on the threads of the screw 8. The centrifugal–screw mixer allow to obtain enriched with amino acids flour baking mix of good quality. The coefficient of heterogeneity of mixes does not exceed 5%. For all samples of bread amino acid content is significantly higher compared to the control sample. Depending on the bread recipe contents of amino acids increased by 83–97% for arginine, 52–61% for tyrosine, 52–66% for phenylalanine, 72–74% for histidine, 91% for leucine+ isoleucine, 53–56% for methionine, 90–97% for valine, 64–72% for proline, 87–93% for threonine, 58–87% for serine and 74% for alanine. The greatest biological value is attributed to flour the baking mix № 1 and № 2. The economic effect of selling an enriched flour bakery mixture prepared on a centrifugal–screw mixer has been determined. It is established that the operating costs for the production of 1 kg of such flour will amount to 0.39 rubles. The prime cost of raw materials for the preparation of 1 kilogram of enriched flour bakery mixture is 50.39 rubles. The payback period of the centrifugal-screw mixer will be 0.02 year.

Migration by ‘direct’ or ‘indirect’ food contact? ‘Dry’ and ‘wetting’ foods? Experimental data for ‘touching’ contact of dry foods with paper and board

Food contact is characterised in various terms, all of which are somewhat ill-defined. This work investigated the simplification that migration from food contact materials into dry food virtually exclusively proceeds through the gas phase, which would imply that the migration of essentially non-volatile components is negligible. It is shown here that this is not necessarily appropriate: for newspaper printed with an ink based on essentially non-volatile polyalphaolefins (PAO) as the main solvent, the migration into polenta and a baking mix reached 64% and 66% respectively of the content in the paper in merely 20 days at ambient temperature. Migration of involatile substances into dry foods implies diffusion through the paper to the small contact points. It depended on particle size, as this determines the density of the contacts. The diffusion rates within the food contact material and the food, including the transfer from one particle to the next, are other determining factors. This leaves the question whether such migration can be modelled or tested in a systematic manner (simulation), or whether it needs to be determined on a case-by-case basis.

Capabilities of laboratories to determine melamine in food—results of an international proficiency test

A proficiency test to assess the capabilities of laboratories to determine melamine in a milk powder and a baking mix, representing starch-containing foods like bread and biscuits, was carried out in January 2009. The need for such an interlaboratory comparison arose from a health scare in China about melamine-tainted powdered milk in the second half of 2008. Laboratories in 31 countries, including Australia, China, India, Japan, New Zealand and the USA, and 21 of the 27 Member States of the European Union participated and reported back 114 results for the milk powder and 112 for the baking mix test materials. The reported results were compared to reference values determined by exact-matching double isotope dilution mass spectrometry. The so-determined assigned values were 10.0 +/- 0.6 mg/kg melamine in the milk powder and 3.18 +/- 0.17 mg/kg melamine in the baking mix. A coverage factor k of 2 was applied to calculate the expanded uncertainties. Three quarters of all reported results for both materials had associated z scores which were satisfactory (z <or= |2|). Of the reported results, 90% was accompanied by a measurement uncertainty statement, and the majority of the measurement uncertainty ranges were reasonable. A number of laboratories were found to underestimate their measurement uncertainties. Methods that involved the use of stable-isotope-labelled melamine were shown to be clearly advantageous with regard to the accuracy of the results. However, no significant influence by other method parameters could be identified.

Determination of melamine in milk-based products and other food and beverage products by ion-pair liquid chromatography–tandem mass spectrometry

This paper describes a fast method for the sensitive and selective determination of melamine in a wide range of food matrices, including several milk-based products. The method involves an extraction with aqueous 1% trichloroacetic acid before the injection of the 10-fold diluted extract into the liquid chromatography–electrospray tandem mass spectrometry (LC–ESI-MS/MS) system, using labelled melamine as the internal standard. As melamine is present in aqueous media in the cationic form, the chromatographic separation in reversed-phase LC requires the use of anionic ion-pair reagents, such as tridecafluoroheptanoic acid (THFA). This allows a satisfactory chromatographic retention and peak shape in all the types of food samples investigated. The method has been validated in six food matrices (biscuit, dry pasta and four milk-based products) by means of recovery experiments in samples spiked at 1 and 5 mg kg −1. Average recoveries ( n = 5) ranged from 77% to 100%, with excellent precision (RSDs lower than 5%) and limits of detection between 0.01 and 0.1 mg kg −1. In addition, accuracy and robustness of the method was proven in different soya-based matrices by means of quality control (QC) sample analysis. QC recoveries, at 1 and 2.5 mg kg −1, were satisfactory, ranging from 79% to 110%. The method developed in this work has been applied to the determination of melamine in different types of food samples. All detections were confirmed by acquiring two MS/MS transitions (127 > 85 for quantification; 127 > 68 for confirmation) and comparing their ion intensity ratio with that of reference standards. Accuracy of the method was also assessed by applying it to a milk-based product and a baking mix material as part of an EU proficiency test, in which highly satisfactory results were obtained.

Audit of manufactured products: Use of allergen advisory labels and identification of labeling ambiguities

The Food Allergy Labeling and Consumer Protection Act became effective January 1, 2006, and mandates disclosure of the 8 major allergens in plain English and as a source of ingredients in the ingredient statement. It does not regulate advisory labels. We sought to determine the frequency and language used in voluntary advisory labels among commercially available products and to identify labeling ambiguities affecting consumers with allergy. Trained surveyors performed a supermarket survey of 20,241 unique manufactured food products (from an original assessment of 49,604 products) for use of advisory labels. A second detailed survey of 744 unique products evaluated additional labeling practices. Overall, 17% of 20,241 products surveyed contain advisory labels. Chocolate candy, cookies, and baking mixes were the 3 categories of 24 with the greatest frequency (> or = 40%). Categorically, advisory warnings included "may contain" (38%), "shared equipment" (33%), and "within plant" (29%). The subsurvey disclosed 25 different types of advisory terminology. Nonspecific terms, such as "natural flavors" and "spices," were found on 65% of products and were not linked to a specific ingredient for 83% of them. Additional ambiguities included unclear sources of soy (lecithin vs protein), nondisclosure of sources of gelatin and lecithin, and simultaneous disclosure of "contains" and "may contain" for the same allergen, among others. Numerous products have advisory labeling and ambiguities that present challenges to consumers with food allergy. Additional allergen labeling regulation could improve safety and quality of life for individuals with food allergy.

Vertical Product Differentiation in Theory and Practice

This study examines the role of advertising on consumers' quality perception as a method to vertically differentiate in the baking mix market. Two companies, General Mills and Chelsea Mills have competed head to head since 1930s, using drastically different strategies. General Mills has consistently promoted Bisquick and provided recipes for its use. Chelsea Mills has never advertised its product, Jiffy, preferring instead to minimize cost and provide service to retailers. Both strategies have been successful, resulting in an equilibrium resembling theoretical vertical differentiation models.

South African Experience with the Use of Red Palm Oil to Improve the Vitamin A Status of Primary Schoolchildren

A randomized, controlled, three-month trial compared the effect of biscuits containing red palm oil as a source of β-carotene and biscuits containing synthetic β-carotene on the vitamin A status of primary schoolchildren. Children consuming either type of fortified biscuit had a significant improvement in serum retinol concentrations compared with control children who received an unfortified biscuit. Using a red palm oil shortening in the biscuit has several other advantages. Unlike the commercial fat normally used in the baking industry, red palm oil contains no trans fatty acids. Because of its high carotenoid and vitamin E contents, the need to add synthetic β-carotene and antioxidant to the baking mix is eliminated. Quality control is simplified. Production costs for the red palm oil biscuit are slightly lower than those for the synthetic β-carotene biscuit. Red palm oil is thus ideally suited for use as a source of β-carotene in food fortification in the baking industry.

Ready-to-eat meals.

As my parents have reached their 80s, they eat more meals prepared by others. Ready-to-eat foods became more appealing to them, as they do to many elders, as buying and preparing food became more difficult or less desirable. Home-delivered meals, part of the Elderly Nutrition Program (ENP) Under the Older Americans Act, reach almost a million older adults with about 114 million meals a year. A single ENP meal provides 40% to 50% of an elder's daily nutrients. Starting this month, some participants will also be getting breakfast. Meals On The Morning Meals On Wheels collaboration between the U.S. Administration on Aging (AoA) and General Mills is providing breakfast to at-risk elders for 6 months. After an evaluation looks at the number of meals served, the factors important for success of a breakfast program, and whether the client's nutrition risk is reduced, General Mills will consider expanding the program nationwide. If they do so, ENP sites can expect a Meals on manual and technical assistance from General Mills, as well as credits, discounts, and allowances on purchases of General Mills products such as yogurt, cereal, and baking mixes. Project staff may even end up pictured on a Wheaties box! Breakfast is an easy meal to add to the ENP projects, because most breakfast foods are served cold and will not spoil, even if kept for several days. Breakfast foods are also relatively inexpensive.
