Rays are usually caught for their high-value fins, but their flesh is also in demand in the tribal areas of the southern Philippines. Export-oriented flesh is mainly salted and dried. Stingrays are not very expensive compared to other commercial marine fish on the local market, but they are high in protein, low in fat, and contain other nutrients as well. Fish flakes are an intermediate moisture fish product that is a favorite snack food among many people. The present study aimed to evaluate the sensory properties of sweet and spicy fish flakes using dried stingray meat with the aid of vinegar (T1) and water (T2) as pre-treatment before adding the other ingredients. The 100 panelists from the local community evaluated newly developed fish flakes. The results showed that the color, odor, texture, and general acceptability scores of sweet and spicy dried fish flakes did not differ significantly (p>0.05) between the two treatments. However, the taste scores showed a significant difference (p

Processing of plant foods has been in practice over a long period of time for various reasons; ranging from optimization of product quality, such as improvement in flavour, texture, nutrient density, and bioavailability as well as reduction in viscosity, bulkiness, and antinutritional factors/toxins or for improvement of functional properties for use in other food systems. Indigenous food fermentation is one of the oldest ‘food biotechnological processes’ dependent on the biological activity of microorganisms from which the development of fermented foods is achieved in the cultural history of human beings. Mango (Mangifera indica) is a tropical fruit plant that contains high levels of nutrients, fibre, macronutrients, micronutrients, and minerals as well as abundant bioactive compounds such as antioxidants and polyphenols reported to be an alternative to enhance body immunity. This study is to process fermented mango pulp flour and the effects of the period of fermentation time on the chemical composition and selected functional properties of mango pulp flours were examined. The fermentation time ranged from 0-72 h with Flour of the unfermented (0hr) Mango serving as control. Fermentation for 24hr to 72hrs significantly increased (p

The aim of this study is to produce a functional product for diets that arise due to preferences such as vegan diet or health problems such as celiac, with the increase of consumer awareness. For this purpose, bars containing various fruits, dried fruits, nuts and spices were produced. For this purpose, 7 different formulations were prepared using design expert. While the ratio of pumpkin and banana was changed in the mixture, the ratios of other ingredients (oats, raisins, cranberries, pumpkin seeds, coconut oil, spice mix, flaxseed) were kept constant. It was determined that the protein content of the bars increased as the amount of pumpkin increased. In the sensory analysis, the gluten-free bars produced were appreciated by the panelists. There was no statistical difference in the ash content, moisture content, oil content and L*, a*, b*, C* color values of the gluten-free bars. The samples were optimized considering their protein content and sensory properties. The formulation with the highest acceptability value (0.884) was determined as the sample containing 75.79 g of banana and 184.21 g of pumpkin.

High molecular weight glutenin subunits (HMW-GS) are the main wheat gluten proteins in flour that determine the viscoelastic properties of various types of dough. In this study, the effects of HMW-GS on various quality characteristics of certain soft wheat biscuit products were investigated. Results of the study showed that subunit 5x + 10y in the Glu-D1 locus increased the gluten strength of a flour and, consequently, negatively affected the physical and sensory properties of the resulting soft-dough biscuit products made with that flour. While product results suggested that the wheat genotypes carrying the allele 1 in Glu-A1 should be selected with care, in terms of biscuit sensory properties, the combination of the null allele in Glu-A1 and subunits 7 in Glu-B1 and 2x + 12y in Glu-D1 can lead to increased success of wheat breeding programs aimed at flours preferred for soft-dough biscuit products. For hard-dough biscuit products, subunit 2* can be used as a marker, in order to eliminate those soft wheat lines having too-high gluten strength. The combinations of HMW-GS 1, 7x + 9y, and 5x + 10y, along with the 1B/1R wheat-rye translocation, were considered to result in flours for production of hard-dough group biscuits. This study suggested that the most suitable HMW-GS combinations of wheat genotypes for soft- and hard-dough biscuit products. Those combinations considering wheat-rye translocation could be used for selection, or elimination, purposes in breeding programs targeting soft wheat varieties for specific baked products.

Bread was enhanced with defatted moringa seed flour in various quantities (0-7.5%) in this investigation. The functional properties of the flour and the physical, proximate, mineral content and sensory attributes of the defatted moringa fortified bread samples were evaluated. The functional properties of the defatted moringa seed flour showed Bulk Density (0.75g/ml), Oil Absorption Capacity (88.45 %), Reconstitution index (76.28 %), Swelling index (8.25 g/vol), Solubility (8.63 %), Viscosity (342.60 cp), and Water Absorption Capacity (82.45 %). Results of the proximate analysis showed that defatted moringa seed flour addition significantly (p < 0.05) increased the protein (13.82–15.39%), fat (1.25–1.56%), ash (1.51–1.61%) and fibre content (0.13–0.18%) of the bread samples, while the moisture (7.85–7.60%), carbohydrates content (75.44–72.88%) and pH (8.05-7.8%) of the bread decreased.

In this study; 8 lactic acid bacteria with antifungal activity and suitable for sourdough production were used in sourdough bread production to determine the effect of bread on prolonging shelf life and to compare with calcium propionate used as a chemical preservative in the food industry/bakery. For this, Weissella cibaria 908, Leuconostoc pseudomesenteroides 2619, Fructilactobacillus sanfranciscensis 2709, Levilactobacillus brevis 2216Y, and L. plantarum subsp. plantarum Y201 isolates were chosen for bread production by paying attention to changes in total acidity and pH values, blistering volumes, organic acid production profiles in bread dough. Total 9 different types of bread were produced. Among them at the end of the study, it was observed that the shelf life of bread containing selected antifungal lactic acid bacteria mixed culture (1:1:1:1:1) and 0.15% calcium propionate was prolonged compared to commercially available breads where 0.3% calcium propionate is allowed. Thus, the use of calcium propionate can be reduced by half. It was observed that there was no significant difference (p>0.05) between the commercially sold and the produced sourdough bread in terms of general admissibility and it was concluded that it can be used in sourdough bread production.

In this study, the ethanolic extracts of leaf and flower of Thymus pseudopulegioides Klokov & Des. Shost collected from Sultan Murat Plateau of Trabzon, Turkey was assessed for total phenolic contents and antioxidant activities. In addition, antibacterial activity of extracts against nine different bacterial strains (Staphylococcus aureus, Escherichia coli, Pseudomanas aeruginosa, Bacillus cereus, B. pumilus, B. subtilis, B. licheniformis, Listeria innocua and L. monocytogenes) were determined using the agar-dilution method. The extraction yields from leaf and flower were obtained as 10.95% and 0.94% (w/w), respectively. The total phenolic contents of leaf and flower extracts were determined as 7.84 and 0.39 mg GAE/g, respectively. Antioxidant activities of the ethanolic extracts from leaf and flower were evaluated by using DPPH radical scavenging, and leaf extract showed better antioxidant activity than flower extract. Although, minimum inhibitory concentration (MIC) of leaf extracts determined as 1.028 mg/mL for all bacteria except B. subtilis (0.256 mg/mL), MIC of flower extracts for B. subtilis and B. pumilis was 0.256 mg/mL and for others was 0.512 mg/mL. The extracts of the tested parts of Thymus pseudopulegioides, especially the leaves might be valuable for functional food and therapeutic applications.
