In this study, sorghum Feterita malt extract was used to prepare carbonated beverages flavored with traditional Hulu-mur spices extract. The beverages produced were assessed for their physicochemical,sensory, and nutritional qualities. Malting (3–5 days) of the Feterita grains showed significant (P ≤ 0.05) differences in proximate composition from that of unmalted grains. Protein and sugars increased significantly (P ≤ 0.05) with increased the malting time (days), while there was a significant (P ≤ 0.05) reduction in oil and starch content during malting progress. The kilning temperature of 150 °C for 20 minutes was found to produce the most acceptable Hulu-mur carbonated beverage analogue in terms of flavor and taste. Significant differences (P ≤ 0.05) were observed in physicochemical and nutritional qualities between the Hulu-mur analogue carbonated beverage and commercial non-alcoholic beverage. The Hulu-mur carbonated beverage analogue was rich in Na, K, Ca, and Fe (26.45, 21.84, 24.00, and 0.57 mg /100 g, respectively) compared to levels of the same minerals in the non-alcoholic beverage (22.31, 8.19, 22.00 and 0.15 mg/100 g, respectively). The Hulu-mur analogue also had a higher calorific value (35.85 kcal /100 mL) compared to the non-alcoholic beverage (32.96 kcal/100 mL).

Elephant foot yams make a significant contribution to diets in tribal people of India. However, there is insufficient study of their nutritional and antioxidant value. In this paper the various traits of eleven cultivars of elephant foot yam: BCA-1, BCA-2, BCA-4, BCA-5, BCA-6, NDA-4, NDA-5, NDA-9, IGAM-1, AC-28 and Gajendra were studied and observed during the growth and development stage. The cultivar of BCA-6 contained the maximum amount of starch and total phenol at 100 Days After Planting (DAP) while cv., NDA-9 and NDA-5 showed the maximum content of starch and total phenol at 250 DAP respectively. However, the cultivar BCA-1 stored the maximum amount of carbohydrate at 100 DAP whereas ascorbic acid and β-carotene content was highest at 250 DAP. The protein amount was maximum in cv., BCA-2 and AC-28 at 100 and 250 DAP respectively. This information will provide breeders with the ability to develop desirable types of elephant foot yams having high yields and better nutritional profiles.

Food technology innovation has the potential to deliver many benefits to society, although some technologies have been problematic in terms of public acceptance. In promoting the commercial success of innovative technological processes and resultant products it will be important to incorporate information relating to consumer preferences and concerns during their development. The barriers to the utilisation of consumer information during technological development was explored using a two round Delphi study involving 75 experts with an interest in new food technology (food technologists and consumer scientists). There was overall agreement that consumer information should be used in technology implementation and product design, and that good communication between key actors at pivotal stages during the development of new food technologies and products was important. However disciplinary differences were perceived to be a barrier to communication, as were difficulties associated with producing consumer information usable by food technologists. A strategy to improve inter-disciplinary communication is proposed, involving the creation of multi-disciplinary teams working together throughout the development project’s duration, including those with interdisciplinary experience. Deficiencies in the specification of the information required from consumer scientists need to be overcome. Consumer science results need to be concrete and presented as salient to and usable by food technologists.

Some of the products generated by the Maillard reaction are desired and very important for defining consumer acceptance of breakfast cereals. However, in recent years there has been an increased concern about compounds that are potentially harmful such as furfurals. The aim of this work was to analyze the effectiveness of protein hydrolysis with pronase as a pretreament for the evaluation of furfurals generated by the Maillard reaction during toasting of cornflakes and the parallel development of brown and fluorescent compounds. Furfurals were more accurately quantified with the pronase hydrolysis pretreatment because the protein matrix binds furfurals and fluorescent compounds. For control of the early reaction steps in the toasting process, the most sensitive parameter was fluorescence.

The main goal of this paper was to conduct an exploratory study regarding consumer preference in the field of Food Science and Technology. Two questions guided this study: Is it possible to identify a trail of crumbs concerning consumer behavior in the Food Science and Technology field? And, if that trail exists, where is it leading academia in terms of research trends of interest? A bibliometric study was conducted using an analysis software called CiteSpace. The use of this methodology ensured the impartiality of the literature review of the topic of interest. A survey of all articles indexed in Web of Science between 1993 and 2013 regarding consumer behaviour was carried out. In total, 1,786 articles were analyzed. The recent increased concern regarding consumer behavior was evident. With the USA and Spain having a significant role in driving the trail. Eight other countries that exhibited similar influences are: Italy, England, Australia, Germany, Denmark, France, Netherlands and Brazil. The research trends observed were grouped into seven major hot topics: sensory, health, safety, willingness to pay, packaging, ethics, and lifestyle/convenience. However, the development of publishing trends depended on where the research was carried out. A final suggestive finding, demonstrated that scientific knowledge does not occur in a vacuum.

The effects of heat blanching and UV-C light followed by heat on Portuguese cabbage peroxidase (POD), colour and texture were studied in the temperature range of 80-95 °C. POD inactivation, lightness (L) and yellowness (b) colour changes were described by a first-order reaction model. The greenness (a) colour and texture (firmness) changes followed a two fraction kinetic model behaviour. The temperature effect was well described by the Arrhenius law. At lower temperatures the combined treatment showed higher POD inactivation. Colour and texture parameters did not show significant differences between treatments. Long processing times turned the leaves slightly darker, decreased greenness, yellowness and firmness. Short processing times increased the firmness and greenness of the leaves. The treatment at 80 °C for 90 seconds reduced 90% of POD, retaining 98% of lightness and 92% of yellowness and improved the green colour (130%) and firmness (125%). At 80 °C the heat blanching required 7.4 min to inactivate 90% of the enzyme activity, reducing lightness, greenness, yellowness and firmness to 92%, 68%, 62% and 61%, respectively. The present findings will help to optimize the Portuguese cabbage blanching conditions.
