During plant-based drinks production a significant amount of valuable by-products (BPs) is obtained. The valorization of BPs is beneficial for both the environment and the food industry. The direct incorporation of the fermented and/or ultrasonicated almond, coconut, and oat drinks production BPs in other food products, such as wheat bread (WB) could lead to the better nutritional value as well as quality of WB. Therefore, in this study, various quantities (5, 10, 15, and 20%) of differently treated [ultrasonicated (37 kHz) or fermented with Lacticaseibacillus casei LUHS210] almond, coconut, and oat drinks preparation BPs were used in wheat bread (WB) formulations. Microbiological and other quality parameters (acidity, color, specific volume, porosity, moisture content, overall acceptability) as well as bread texture hardness during the storage and acrylamide content in the WB were evaluated. Among the fermented samples, 12-h-fermented almond and oat, as well as 24-h-fermented coconut drinks preparation BPs (pH values of 2.94, 2.41, and 4.50, respectively; total enterobacteria and mold/yeast were not found) were selected for WB production. In most cases, the dough and bread quality parameters were significantly (p ≤ 0.05) influenced by the BPs used, the treatment of the BPs, and the quantity of the BPs. The highest overall acceptability of the WB prepared with 20% fermented almond drink preparation by-product (AP), 15% fermented oat drink preparation by-product (OP), and 15% ultrasonicated OP was established. After 96 h of storage, the lowest hardness (on average, 1.2 mJ) of the breads prepared with 5% fermented AP, coconut drink preparation by-product (CP), and OP and ultrasonicated CP was found. The lowest content of acrylamide in the WB prepared with OP was found (on average, 14.7 μg/kg). Finally, 15% fermented OP could be safely used for WB preparation because the prepared bread showed high overall acceptability, as well as low acrylamide content.

The aim of this study was to evaluate the contribution of extruded and fermented wheat bran (WBex-f) to the quality of wheat bread (BR), including the volatile compounds (VC) profile and VC relationship with emotions induced for consumers. A comparison study of BR (prepared with 5%, 10%, and 15% untreated wheat bran (nWB) and WBex-f) quality parameters was performed. It was established that nWB increases dough hardness and reduces BR specific volume. The addition of 5% and 10% of WBex-f was not significant on BR porosity and led to the formation of a high number of large pores. nWB and WBex-f increases the mass loss of BR after baking (by 13.38%), and the control breads showed the highest crust darkness, yellowness, and redness. nWB and WBex-f reduces BR firmness during storage, and WBex-f increases the overall acceptability (OA) of BR (by 26.2%). A strong positive correlation was found between OA and the emotion ‘happy’ (r = 0.8696). In BR prepared with WBex-f, a higher content of pyrazine, methyl-; pyrazine, 2-ethyl-; pyrazine, 2-ethyl-6-methyl-; furfural; ethanone, 1-(2-furanyl)-; benzaldehyde; and 3-furanmethanol was found. Finally, it can be stated that WBex-f could prolong the shelf life of BR and leads to the formation of a specific VC profile, which is associated with a higher OA of the product.

Plant protein concentrates are used to enhance the nutritional quality of bread and to respond to the demand of consumers with respect to increased protein intake. In the present study, bread samples were produced using pea protein concentrate (PP) and soy protein concentrate (SP) substituting wheat flour by 5%, 10%, and 15%. The protein levels were between 1.2- and 1.7-fold (PP) and 1.1- and 1.3-fold (SP) higher than the control bread. The incorporation of 10% and 15% PP allowed for the achievement of a “high protein” claim. Water absorption was correlated with the protein contents of the breads (r = 0.9441). The decrease in bread volume was higher for the PP than SP incorporations, and it was highly negatively correlated with the protein content (r = −0.9356). Soy breads had a softer crumb than pea breads. The total change in crumb colour was higher in the PP than SP breads. The soy breads had an overall acceptability between 6.3 and 6.8, which did not differ (p > 0.05) from the control. PP breads were statistically less liked (p < 0.05). The results underlined that the choice of the type and amount of protein concentrates influenced the bread properties differently.

AbstractBy-products from fruits and vegetables are slices and peels that have been removed or rejected by the food industry and are considered to have low commercial value. Pumpkin peel is a source of carotenoids, minerals, antioxidants and phenolic compounds. This work studied the nutritional value of pumpkin peel flours produced by convective drying (40 °C) and milling. Pumpkin peel flours contained high contents of insoluble fibres (24.46 g/100 g), potassium (19.1 g/kg) and iron (152.5 mg/kg). Carotenoids were extracted using hexane at 40 °C, and flour particles were classified by 35-, 80- and 100-mesh sieves. The total carotenoids content ranged from 216.9 to 306.8 μg/g. Fick’s second law model computed that 215 min was required to extract 99 % of the total carotenoids. This work evidenced the effects of particle size on carotenoids extraction efficiency and demonstrated that pumpkin by-product flour could be used as a food ingredient or natural dye.

Amaranth Flour

Pseudocereals are as good as the true cereals in many aspects of nutritional value. Either substituting or supplementing the staple cereals with pseudocereals and thereby improving the nutritive value of foods are under experimentation. Amaranth, a pseudocereal possess the usual characteristics of cereals such as bland taste, ease of cooking and also contain a substantial quality of cooking and fat as compared to most cereals.  Amaranth contain good amount of fiber, energy and mineral than the conventional grains. Nevertheless, amaranth grain is still considered as a underutilized food crop and its consumed very few places. The usage of amaranth green, though very common in many parts of India. Development of nutritionally superior inexpensive food and acceptable to intended consumer is the biggest challenge of the present time. The present investigation was designed to develop high protein product by incorporation of amaranth flour. Amaranth flour was incorporate in the ratio of 20, 30, 40, 50, 60 and 70 per cent in the wheat flour. The higher score of overall acceptability was 7.70± 0.10 for 50 per cent substitution of amaranth flour after control and the minimum as 6.67± 0.25 for the 70 per cent amaranth flour noodles. Considering the results obtained and characteristics of flour used, the amaranth flour addition up to 30 per cent is evident to improve some nutritional properties and 50 per cent for sensory characteristic. Results also showed significant increase (P<0.05) in the protein (13.22 g) when compared with control (12.07 g). In this research it was analyzed that the different amount of amaranth flour plays an important role in noodles making by enhancing nutritional parameters and overall product quality. Resultant noodles can be used as a nutritious food with higher content of protein and other nutritious elements in an increased market of noodle product where quality protein is an issue.

The search for waste minimization and the valorization of by-products are key practices for good management and improved sustainability in the food industry. The production of almonds generates a large amount of waste, most of which is not used. Until now, almonds have been used for their high nutritional value as food, especially almond meat. The other remaining parts (skin, shell, hulls, etc.) are still little explored, even though they have been used as fuel by burning or as livestock feed. However, interest in these by-products has been increasing as they possess beneficial properties (caused mainly by polyphenols and unsaturated fatty acids) and can be used as new ingredients for the food, cosmetic, and pharmaceutical industries. Therefore, it is important to explore almond’s valorization of by-products for the development of new added-value products that would contribute to the reduction of environmental impact and an improvement in the sustainability and competitiveness of the almond industry.

The paper examines the effect of native and germinated pumpkin and watermelon seeds on the quality of semi-finished and finished bread products. Native and germinated seeds, pre-dried and ground into flour, were used as an additive to bread in the amount 5%, 10%, 15% by weight of the flour. Pumpkin and watermelon seeds were added in order to enrich the bread with micronutrients. The influence of these additives on the quantity and quality of gluten has been analysed. It has been found that the addition of pumpkin seed flour in quantities of 5%, 10% and 15% by weight of wheat flour leads to a decrease in the gluten content and an increase in its elasticity. The study has shown that adding native pumpkin seeds does not have a significant effect on the moisture and acidity of semi-finished and finished products, and adding germinated seeds leads to a slight increase in these parameters. Thus, the moisture content of the crumb with native pumpkin and watermelon seeds added increased by 0.2–1.3%, as compared with the reference sample, and with germinated seed flour added, it increased by 0.5–2.2%. The acidity of the crumb changes slightly, within experimental error. According to the physicochemical quality parameters, the most practical amount of the additives is 5% by weight of wheat flour. A comparative analysis has been carried out to establish how addition of 5% of native and germinated pumpkin and watermelon seeds changes the organoleptic properties of bread. The analysis has shown that ready-made bread products containing native pumpkin seeds taste better and have better olfactory properties than products with germinated seeds. The nutritional and calorific values of the reference sample and of bread with 5% of pumpkin and watermelon seed flour have been compared and characterised. It has been found that the addition of native pumpkin seeds will increase the content of minerals: of iron by 230%, of magnesium by 116%, and of potassium by 118%. The addition of native watermelon seeds will increase the phosphorus content by 13%. As a result of this research, the prospects of using flour of native pumpkin and watermelon seeds to fortify wheat bread have been shown

Dairy free milk alternative was obtained from cashew nut, coconut while skimmed milk from cow was used as reference standard. The prepared milk samples were analyzed for proximate, minerals and sensory attributes. The result revealed a reasonable amount of protein (12.26%) and coconut milk for cashew milk, 11.17% for soymilk, 8.52% for coconut milk while the standard cows skimmed milk, values obtained for cashew milk of 72.67%, soymilk and coconut milk was 64.22% contain the highest of 0.69 for ash while the plant milk also contain appreciable quantity which is directly related to the mineral content of the milk alternative. Cashew nut milk had the lowest pH values of 6. 10 and the lowest specific gravity of 1.010 g/cm3 . Fat content was high for cashew nut milk compared with the other milk samples. Sensory evaluation performed indicated that cashew milk was most preferred for the attributes of colour, mouthfeel while it ranked next to skimmed milk in taste and flavor. Cashew milk was ranked highest with values of 8.33 for overall acceptability compares well with skimmed milk with the value of 8.46 while the other milk alternatives had the values of 6.22 and 6.44 for soy milk and coconut milk respectively. The results therefore indicate that cashew milk can be used as alternative to dairy milk.

Apple based beverages are rich source of sugars and dietary fibres but deficit in proteins and some minerals like calcium. Whey- a major environmental pollutant from dairy industry is an excellent source of proteins and calcium. Non-nutritive sweeteners can be used for the development of low calorie hypoglycaemic beverages. Therefore, the present work was planned to optimize and evaluate the effect of fructooligosaccharide (FOS) incorporation on physico-chemical, nutritional and sensory characteristics of apple-whey blended ready-to-serve beverage. Herbal apple-whey blended beverage was prepared by using 75% apple juice+25% whey with 2.5% jaljeera extract and 13oB TSS. Results revealed that the beverage with 75% sweetos (mixture of fructooligosaccharide and sucralose) was found most acceptable with overall acceptability score of 8.59±0.26. Selected beverage had 12.20±0.01oBrix TSS, 0.30±0.01% acidity, 6.28±0.03% reducing sugar, 9.43±0.06% total sugars, 10.57±0.05 mg/100 g ascorbic acid, 37.84±0.03 mg/100 g total phenols, 15.64±0.02 mg/100 mL calcium, 0.28±0.03% protein and 1.59±0.03% FOS thus depicting enhanced nutritional value. Beverages were stored successfully for a period of 60 days under ambient and refrigerated conditions. However, various quality parameters of RTS beverage were retained higher under refrigerated storage conditions. Conclusively, this creates a scope for better health beverage as well as efficient utilization of whey.
