Aims: Asparagus racemosus is locally known as shatavari in India and possess a strong antioxidant and galactogogue activities. This study was aimed to reduce the bitterness of Asparagus racemosus root powder (ARRP) and to analyse the effect of storage on acceptability and oxidative rancidity of ARRP fortified biscuits. Study Design: Biscuits were developed substituting whole wheat flour with 5, 7.5 and 10 per cent of ARRP. Methodology: ARR were blanched to eliminate the bitterness in developed powder. Developed biscuits were analyzed for sensory characteristics using 9-point hedonic scale by 25 semi-trained panelists. Biscuits were packed in plastic zipper bags and stored in an airtight plastic container at room temperature for 90 days. Effect of storage period on sensory acceptability, fat acidity and peroxide value of biscuits was observed. Results: Blanching of A. racemosus roots at 80ºC temperature for 3 minutes reduced the bitterness of developed powder considerably. Results showed that biscuits were found to be ‘liked moderately’ on 9-point hedonic scale. During storage period of 90 days, the scores of sensory characteristics were decreased gradually for colour, appearance, aroma, taste, texture and overall acceptability, however biscuits were found acceptable by panellist. The increase in oxidative rancidity with the advancement of storage period was observed in terms of fat acidity (mg of KOH/g) and peroxide value (meq of O2/kg) in control as well as ARRP biscuits however, this increase was witnessed less in A. racemosus fortified biscuits than control. Conclusion: ARRP upto 10 per cent can be successfully used in the development of products with increased shelf life along with galactogogue activity.

A study was carried out from 1st July to 21st October 2003 at the Institute of Animal Science (IAS), University of the Philippines, Los Baños, College Laguna, Philippines. The study was based on the overall acceptability of substitution of sodium chloride by potassium chloride, frankfurters of broiler chicken and buffalo meat, which were prepared with or without garlic at 1:1 ratio. Frankfurters stored in chiller for over-night after the preparation (as fresh) and stored in freezer (-5 to -7°C) were taken out at 45 and 75 days for sensory evaluation. Ten experienced panelists were involved to evaluate sensory characteristics of frankfurters. Required amount of franks were cut into approximately 2.5 cm size and heated in microwave before serving to the panelists after randomly coding. Each panelist was served with four randomly allocated samples such that in each replication (block), two panelists were assigned. Juiciness, tenderness, color, flavor, off-flavor and overall acceptability were evaluated using the seven point Hedonic scale score card. Type of meat used and the storage period had significant influence in some of the sensory traits, such as juiciness, tenderness and color. Scores for juiciness and tenderness were significantly (P>0.05) higher with chicken franks. However, highly significant (P>0.01) difference was observed for color, favoring buffalo meat franks. Traits such as flavor and overall acceptability had higher scores for chicken than buffalo meat, although scores for offflavor had opposite values; higher with chicken, but was not significantly different. Sensory characteristics for stored products were scored lower than fresh. Color was influenced significantly (P>0.05) by meat type, salt, garlic and also storage period of 75 days. Meat type and storage interaction had significant (P>0.05) differences on juiciness, overall acceptability and tenderness. However, their effects as individual variable were not significant. When garlic was used at 2% level in combination with NaCl+KCl at 1:1 ratio the effectiveness was more pronounced from all respects. However, same percentage of garlic could not produce more acceptable franks with sodium chloride alone. All sensory parameters considered in the study were scored less either for 45 or 75 days storage than the fresh. However, statistically; except for off-flavor, no significant differences were observed between 45 and 75 days.

Four commercially produced dahi samples were stored under 0°C, 10 °C and 20 °C temperatures subjected to microbiological examination, pH, titrable acidity and sensory attributes at various temperatures for a period of seven days. The results indicated an increase in microbial activity parameters and titrable acidity with increase in temperature and storage period. pH of dahi samples decreased with an increase in temperature and storage period indicating increase in acidity. The studies for microbiological studies shows increase in TPC along with the increase in days of storage. Similar case was found in Yeast and mould as well as in Coliform count. The TPC at refrigerated storage was observed as (1.69±0.58)106 to (5.0±0.68)106 while as at 20°C temperature it was observed as (1.5±0.35)106 to (4.5±0.12)10. Similarly the Yeast and mould count at refrigerated storage was observed as (1.0±0.92)106 while as at 20 °C temperature it was observed as ( 1.5±0.36)106 .The different samples of dahi were analysed for various sensorial attributes for their acceptance by using 9 point hedonic scale. The scores obtained with respect to colour, flavour, taste and aroma show good results and overall acceptability. Overall acceptability was also found to decrease significantly (p <.05) with increase in days of storage under refrigerated conditions. The results of the storage studies indicated the significant (p < .05) decrease in pH with the days of storage under different temperature conditions.

AbstractObjectiveBread is the largest contributor of Na to the American diet and excess Na consumption contributes to premature death and disability. We sought to determine the Na level at which consumers could detect a difference between reduced-Na bread and bread with typical Na content, and to determine if consumer sensory acceptability and purchase intent differed between reduced-Na bread and bread with typical Na content.DesignDifference testing measured ability to detect differences in control bread and reduced-Na bread using two-alternative forced choice testing. Acceptability was measured using a nine-point hedonic scale and purchase intent was measured using a five-point purchase intent scale.SettingDifference and acceptability testing were conducted in Portland, OR, USA in January 2013.SubjectsEighty-two consumers participated in difference testing and 109 consumers participated in acceptability testing.ResultsConsumers did not detect a difference in saltiness between the control bread and the 10 % reduced-Na bread, but did detect a difference between the control bread and bread reduced in Na content by 20 % and 30 %. Na reductions had no effect on consumer acceptability of sensory characteristics, including overall liking, appearance, aroma, flavour, sweetness, salt level and texture, or purchase intent.ConclusionsReducing Na levels by up to 30 % in the sandwich bread tested did not affect consumer liking or purchase intent of the product. These results support national recommendations for small, incremental Na reductions in the food supply over time and assure bread manufacturers that sensory characteristics and consumer purchase intent of their products will be preserved after Na reductions occur.

Experiments were conducted to evaluate quality attributes of biscuits using wheat, sorghum and groundnut blend flour. Study was also conducted to see the effect of blend flours treatments on textural characteristic and sensory evaluation. Flours blend were prepared with various combination of wheat, sorghum and groundnut as W80: S15: G05 (T1), W70: S20: G10 (T2) and W60: S25: G15 (T3). Textural characteristics viz., fracturability, hardness, cohesiveness, adhesiveness through texture analyzer. The sensory characteristics viz., colour, odor, flavour, taste, texture and overall acceptability were evaluated for fresh, 30, 60 and 90 days of storage period. The maximum hardness was found in sample prepared for treatment T2 (2752.70 g), whereas higher cohesiveness value was obtained in sample of treatment T1 (1.67). The adhesiveness and springiness were obtained maximum in sample of treatment T3 (8.47 g.s) and treatment T2 (2.09 mm), respectively. The gumminess and chewiness value were found highest in sample of treatment T2 (4349.26 g) and treatment T2 (9056.48 g.mm), respectively. Sensory characteristics as colour, odor, flavour, taste and overall acceptability were scored highest rating in T2 treatment as compared to T1 and T3 treatments. Sensory score was decreased with increase of storage period in all treatments. Fresh biscuit samples prepared with wheat 70% + sorghum 20% + groundnut 10% rated highest score (7.8) than other treatments. The treatment (T2) gave better product in view of colour, odor, flavour, taste and overall acceptability as well as textural quality attributes.

Biscuit consumption is considered one of the top ten daily consumed foods [1]. The objective of this study was acceptability of biscuit containing three different combinations of powders of wheat bran, flaxseed and wheat viz., 25:75:0, 0:50:50, 20:80:0 were used to prepare 100gms flour mix. Acceptance was assessed using a hedonic scale of nine points. It was noticed that incorporation of flaxseed flour at 80% was unacceptable in biscuit. At this level of incorporation of flaxseed flour, the sensory properties of the product were affected i.e., flavour and taste wise, body and texture, colour and appearance and overall quality whereas 75% addition of flaxseed flour produced good results [2]. The antioxidant activity, phenolic concentration was linearly increased as the fortification was increased [1]. Data revealed that the overall acceptability of biscuit ranged from 9 to 7. This indicated that the recipes were found to fall under the category of ‘like extremely to like moderately’. It can finally be discerned from the sensory scores for biscuit prepared with 75% incorporation of flaxseed flour with 25% of wheat bran flour, that the biscuit was equally acceptable as that of control [2]. The acceptability of sensory characteristics was improved by this fortification immediately after preparation and during storage [3].

This study evaluated the sensory properties of uncooked and cooked milled lentils that were fortified with varying concentrations of Fe and Zn in the form of NaFeEDTA and ZnSO4.H2O, respectively. Our study was carried out among 196 lentil consumers residing in rural Bangladesh who experience with growing, processing, and marketing lentils. A nine-point hedonic scale was used to rate the appearance, odor, taste, texture and overall acceptability of three uncooked and two cooked lentil (dal) samples made from each of the three milled lentil product types (LPTs), red football, red split and yellow split. Preferences for sensory properties were found to be significantly different among all uncooked lentil samples, but not significantly different for cooked samples, with a few exceptions. This means that the fortification process minimally affects dual-fortified lentil sample (fortified with 16 mg of Fe and 8 mg of Zn per 100 g of lentil), which was compared to another cooked sample (unfortified control), in terms of consumers liking for all four attributes (appearance, odor, taste, and texture).

Ruspolia nitidula (an edible grasshopper) is a seasonal delicacy in Uganda and its neighbouring countries, with a postharvest shelf stability of 1-2 days. Our previous processing research increased the shelf stability of ready-to-eat R. nitidula to 12 weeks at ambient temperature. However, there is need to double the shelf-life to cover the 20-24 weeks between swarming seasons and, increase the efficiency and cost effectiveness of the processing and packaging techniques developed. This research investigated the effectiveness of 9 preservation hurdles on the microbial (total plate count), sensorial (overall acceptability) and chemical (acid value, peroxide value and thio-barbituric acid value) stability of ready-to-eat R. nitidula. Chilled storage and ambient temperature storage of the vacuum packed product increased the shelf stability of R. nitidula from 12 to 22 weeks. After 22 weeks of storage, the products had an overall acceptability of 6-7 on a 9-point hedonic scale, a total plate count of <4 log cfu/g, an acid value of approximately <1 mg KOH/g, a peroxide value of <21.50 meq O2/kg and a thio-barbituric value of <0.079. Either chilled storage or vacuum packaging are suitable means of preserving dried ready-to-eat edible grass hoppers and can be used depending on availability. Further research into increasing the shelf stability of R. nitidula at room temperature will be very beneficial to its commercialisation.

Introduction: Incessant health risks associated with chemical preservatives have resorted to the need of exploring natural alternatives with antioxidant potentials in meat processing. In this study, the effect of Ocimum basilicum (OBE) and Gongronema latifolium (GLE) extracts were evaluated in smoked beef during 9 days of room storage (25±1°C). Methodology: Beef samples were prepared from freshly cut rounds (2 kg each) allotted to four groups containing Nitrite, OBE, GLE and OBE+GLE respectively. Prepared beef samples were subjected to physicochemical (cooking loss, yield and colour), sensory characteristics, pH and lipid oxidative analyses. Data were analysed using descriptive statistics and ANOVA at α0.05. Results: No significant change was observed in cooking yield and colour although higher values occurred in control samples. OBE and GLE inclusions exhibited a marked potential in sensory characteristics such as flavour, texture, tenderness, juiciness with the panelists rating the latter as the samples with overall acceptability. Results in storage period showed a significant progression in TBARS and pH values in all treatments with the highest and lowest values observed in control and OBE treatments. Conclusion: GLE treated beef showed a marked efficacy throughout the storage period than the other extract-treated samples. With the need to provide natural alternatives against chemical preservatives, exploring its synergistic effects with other cheap, accessible and rich bioactive sources will be imperative in shelf life extension of meat.

Maasa is a spontaneously fermented millet-based fried cake in Ghana. Nixtamalization, a process of cooking and soaking cereals (usually maize) in lime solution, was applied in the traditional processing of the Ghanaian millet-based fermented maasa. During the processing, Lime cooked millet dough (LCMD) and water soaked millet dough (WSMD) samples were analyzed for proximate composition, pH, total titratable acidity and microbial counts were assessed for fermenting millet dough samples. Finally, maasa prepared from nixtamalized and non-nixtamalized fermented millet dough samples were assessed for consumer sensory acceptability on a five-point hedonic scale. Nixtamalization improved crude protein and ash contents of millet dough samples whereas fat and fiber contents decreased. During fermentation, a reduction in pH and increase in total titratable acidity was observed for both nixtamalized and non-nixtamalized millet dough samples. Lactic acid bacteria (LAB) and yeasts count reached 9.4 and 8.0 logcfu/g respectively for non-nixtamalized millet after 14 hours of fermentation, whereas for nixtamalized millet samples, LAB and yeasts count reached 7.6 and 7.5 logcfu/g respectively. Consumer sensory evaluation of Maasa produced from nixtamalized fermented millet had improved texture, colour and overall acceptability as compared to the traditional non-nixtamalized fermented millet-based maasa. Nixtamalization can thus be applied in the production of Ghanaian millet-based maasa to improve nutritional quality and acceptability as well as maintain the benefits associated with traditional cereal fermentation.
