Whole Grain Muffin Acceptance by Young Adults

Health Effects of Whole Grains: A Bibliometric Analysis

Whole grains have been recommended in the diet in most countries, with numerous publications focusing on their health effect. A systematic analysis of these publications on different research methods, regions and perspectives will contribute to an understanding of the innovation pattern in this field. This bibliometric study analyzes the global publication characteristics, hotspots and frontiers of whole grain health benefit research, and discusses the trends and prospects of this topic. The overall number of publications is on the rise, with the United States contributing the most publications. The most cited literature shows that observational studies, systematic reviews and meta-analysis are the most widely used methods. The main focus in this area is on dietary fiber and bioactive substances, while the latter has received increased attention in recent years in particular. With the increasingly prominent problems of hidden hunger and chronic disease, the development of whole grain foods and their optimum intake have gradually become hot topics. In addition to the need to reveal the mechanism of whole grain health effects, consensus needs to be reached on standards and definitions for whole grain foods, and attention should be paid to the retention of taste and healthy nutrients in processing.

Familiarization with White Whole Wheat Improves Acceptability of Whole Grain-Based Baked Products Made with White Whole Wheat Among College Students

Research corroborates that high whole grain intake is associated with lower risk for obesity, type 2 diabetes, cardiovascular diseases, and cancers. Unfamiliarity with, and negative sensory appeal of whole grains limit voluntary food choices to increase their consumption. This study aimed to explore the effectiveness of familiarization with white whole wheat, to improve college students’ acceptability of shortened cakes, muffins, and yeast breads made with white whole wheat flour (WWWF). All-purpose flour (APF) was replaced with WWWF in standardized recipes, and the products scored by 102 college students. Independent t-test was used to analyze if sensory scores for appearance, taste, texture, and overall acceptability between APF and WWWF products were statistically significant. Before familiarization with WWWF, all three APF products scored significantly higher than whole grain counterparts ( P < .05). When participants were familiarized with health benefits and expected sensory profile of whole grain products, sensory scores for appearance, taste, and overall acceptability of WWWF products did not significantly differ from APF counterparts ( P > .05). Familiarization significantly increased overall acceptability scores of WWWF products ( P < .05). Familiarization also increased proportion of students willing to bake with WWWF. Results underscore that familiarization can improve acceptability of WWWF in baked products and students’ willingness to incorporate it in baking, with potential to stimulate dietary modifications.

Physico-Chemical, Textural and Sensory Evaluation of Spelt Muffins Supplemented with Apple Powder Enriched with Sugar Beet Molasses

The present study investigated the effect of incorporating 10, 20, and 30% apple powder obtained by freeze-drying, and apple powder produced with osmotic pre-treatment in sugar beet molasses solution, into muffins. The powder was freeze-dried and introduced as a whole spelt wheat flour replacement in muffins. The obtained products were investigated for their chemical composition and technological properties, and were subjected to a sensory analysis as well as a consumer acceptance test. Increasing the substitution level from 0 to 30% apple powder lowered the protein, starch, and fat content, while moisture content, sugar, and cellulose showed the opposite trend. The sensory analysis results indicated that the addition of apple powder or apple powder with osmotic pre-treatment (apple OT+Lyo powder) to the ingredients of muffins positively affected the taste, smell, mastication, and appearance of the final product. Consumers rated the muffins with 30% apple OT+Lyo powder as the most acceptable. Principal component analysis, an artificial neural network, and global sensitivity analysis were utilized to differentiate among muffin samples, and to estimate the corresponding influence of the substitution of spelt flour with apple powder or apple OT powder on the observed quality and nutritional parameters of the muffins.

Determinants of US University Students' Willingness to Include Whole Grain Pasta in Their Diet

College students’ lifestyle and eating habits strongly affect their health. Among many healthy eating behaviors, including whole grain food in the diet is known as providing health benefits such as maintaining a steady blood sugar, lower cholesterol, and since it is rich in fiber and minerals, it is essential for the well-being. However, consumers’ intakes of whole grain products remain below recommendation, including college students. This study aims to evaluate determinant factors contributing to college students’ willingness to include whole grain pasta in their diets. A sample of 499 students enrolled in a US college participated in this study. Most students perceived whole grain pasta as healthy and filling and somewhat tasty. Availability and price were not barriers for consumption. Logistic regression results suggested that factors affecting students’ willingness to consume whole grain pasta in the future were the desire to eat, cognitive and affective attitudes, perception of whole grain pasta, as well as having already chosen pasta thanks to its availability at the dining. Two student segments were identified according to their healthy eating perception: Uninvolved and Health-conscious. Cognitive attitudes such as beneficial and essential had positive effects on consumption in both segments, suggesting that information provision covering specific health/nutritional benefits of whole grains for students is crucial.

Main Factors Influencing Whole Grain Consumption in Children and Adults-A Narrative Review

Despite their recognized health benefits, intakes of whole grains (WG) are below recommended levels in almost all countries worldwide. This observation highlights the need to increase WG consumption by understanding factors influencing this consumption and how they could be favorably impacted. This review focused on facilitators of and barriers to WG consumption and how to improve the effectiveness of programs aiming at increasing WG consumption. The main methods to facilitate WG intakes in both adults and children seem to be to (i) increase the availability and the variety of foods containing WG, (ii) improve their sensory appeal, (iii) reduce their purchase cost, (iv) use a familiarization period to introduce them to consumers (with a gradual increase in consumed amounts and repeated exposure), and (v) improve communication and labeling to enhance consumers’ ability to identify products with WG. These strategies may be used to improve the effectiveness of programs aiming at promoting WG consumption, with a further emphasis on the need to apply them over a long period of time, and potentially to include tasting sessions of new foods containing WG. Finally, these strategies should involve broad partnerships between multiple stakeholders at the regulatory, institutional and industrial levels.

Review of the Sensory and Physico-Chemical Properties of Red and White Wheat: Which Makes the Best Whole Grain?

Establishing sensory and physico-chemical differences between products made from red and white wheat may guide the choice of wheat for use in whole grain and high fibre products. As sensory acceptance is key to consumption, this scoping review aimed to document sensory and physico-chemical research demonstrating quantitative differences in red and white wheat and the associated bran. The following databases were systematically searched following the PRISMA protocol: PubMed, Medline, Scopus, CINHAL and ScienceDirect (1990–2019). Of 16 studies, 13 were sensory studies with 529 participants (six of which included quantitative analysis) and three additional quantitative studies. Overall, 10 studies were in favour of white wheat (seven sensory studies, two focused on quantitative analysis and two with additional quantitative studies). Whole grain (wholemeal) bread, pita bread, crackers, noodles, tortillas, flour, intact grains and bran were examined. Aside from the seed coat colour, levels of bound versus free phenolic compounds and polyphenol oxidase activity appeared most responsible for the differences in red and white wheat. Ensuring the sample size for sensory studies are large enough to detect between-group preferences and linking to physico-chemical analysis are recommended. Attention to blinding techniques in sensory testing and use of food products realistically and consistently prepared with commercial potential are also suggested. This scoping review provides confidence in preference for white wheat for whole grain products, particularly for breads, tortillas and in the choice of white wheat for products suitable for the Asian market.

Infant Cereals: Current Status, Challenges, and Future Opportunities for Whole Grains

Infant cereals play an important role in the complementary feeding period. The aim of this study was to review existing research about the quantity, type, and degree of infant cereal processing, with a special focus on whole grain infant cereals. Accumulating evidence shows many benefits of whole grain consumption for human health. Likewise, consumers are frequently linking the term whole grains to healthiness and naturality, and sustainable food production becomes a more important aspect when choosing an infant cereal brand. Whole grain cereals should be consumed as early as possible, i.e., during infancy. However, there are several challenges that food manufacturers are facing that need to be addressed. Recommendations are needed for the intake of whole grain cereals for infants and young children, including product-labeling guidelines for whole grain foods targeting these age stages. Another challenge is minimizing the higher contaminant content in whole grains, as well as those formed during processing. Yet, the greatest challenge may be to drive consumers' acceptance, including taste. The complementary feeding period is absolutely key in shaping the infant's food preferences and habits; therefore, it is the appropriate stage in life at which to introduce whole grain cereals for the acceptance of whole grains across the entire lifespan.
