In recent years, due to its medicinal properties and reputation as a healthy vegetable, consumption of okra (Abelmoschus esculentus L.) has considerably increased in China. In this study, texture parameters (hardness, springiness, cohesiveness, gumminess, chewiness, and resilience) of okra fruit subjected to chitosan (CTS) treatment and control were determined during storage. The changing pattern of texture properties and the differences between three different cultivars (Kariba, ACF, and Xianzhi) were observed at three testing stages (0, 15, and 30 days of storage), which indicated a significant cultivar-dependent pattern. The hardness, cohesiveness, gummi-ness, chewiness, and resilience of the fruit, both in the 1% CTS treatment group and the control group, declined along with storage time. The small fruits (length < 10 cm) scored relatively low in most of the texture parameters and rate of intact when compared with large (length ? 15 cm) and medium-sized fruits (10 ? length < 15 cm). There was a significant, positive correlation between firmness, cohesiveness, gumminess, chewiness, and resilience. Our results revealed that a 1% N, O-carboxymethyl CTS solution can effectively delay softening and maintain the texture profile of the okra fruit. In the case of Kariba (A) and Xianzhi (C), the medium-sized fruits showed better storage resistance, while the large fruit of ACF (B) showed the best storage resistance.

AbstractObjectiveTo examine whether parents offering a sticker reward to their child to taste a vegetable the child does not currently consume is associated with improvements in children's liking and consumption of the vegetable.DesignA randomized controlled trial evaluated the effectiveness of exposure only (EO) and exposure plus reward (E + R), relative to a control group, on children's liking and consumption of a target vegetable. Assessments were conducted at baseline and 2 weeks from baseline (post-intervention). Follow-up assessments were conducted at 4 weeks and 3 months from baseline.SettingThe study took place in Adelaide, South Australia. Participants were self-selected in response to local media advertisements seeking to recruit parents finding it difficult to get their children to eat vegetables.SubjectsParticipants were 185 children (110 boys, seventy-five girls) aged 4–6 years and their primary caregiver/parent (172 mothers, thirteen fathers).ResultsThe E + R group was able to achieve more days of taste exposure. Both EO and E + R increased liking at post-intervention compared with control and no further change occurred over the follow-up period. All groups increased their intake of the target vegetable at post-intervention. Target vegetable consumption continued to increase significantly over the follow-up period for E + R and control but not for EO.ConclusionsThe findings provide support for the effectiveness of using a sticker reward with a repeated exposure strategy. In particular, such rewards can facilitate the actual tastings necessary to change liking.

Precise Assessment

Each year the assortment of fish oil fortified foods increases. Fish oil is a rich source of long chain omega-3 polyunsaturated fatty acids (PUFA) which low intake results in less protection against many common diseases. According to recommendations the level of omega-3s in average diet should be increased. Consumption of foods fortified with fish oil may elevate omega-3 intake. Such fortification, among others, may influence the texture of food product because of liquid form of added fish oil. The aim of this study was to evaluate the influence of fortification with 30 g kg-1 of fish oil on selected texture properties of reduced-fat spread by sensory and instrumental assessment during 3 months of storage. Samples were prepared on industrial pilot plant. Hardness, spreadability, consistency and adhesiveness were measured by sensory and instrumental methods (Texture Analyser TX.TA2i). During storage time results of measurements of all evaluated attributes were comparable to controls. Slight increase in hardness and consistency was observed. It is concluded that fortification with 30 g kg-1 of fish oil used in the study has no significant effect on texture properties of evaluated spread. Combined instrumental and sensory methods may assure precise assessment of texture parameters in the quality control of spreadable fat production.

AbstractThe texture profile analysis test is an imitative test to determine texture properties of food, which quantify the consumer’s perception of eating food. The instrumental texture parameters obtained from this test depend on the specimen size and the nonstandardized test conditions. To overcome this problem, texture properties are here related to intrinsic mechanical properties, which are independent of the test conditions. Two types of materials are used to investigate the effect of viscoelasticity, plasticity and damage on the texture parameters for varying test conditions. Analytical relations between mechanical properties, test conditions, and the instrumental hardness, springiness, cohesiveness, and adhesiveness are determined. The hardness is obtained from the stiffness of the material, which is potentially rate-dependent, and the yield stress of a material in case of plasticity. The springiness is determined by the recoverable or irrecoverable strain in the material, which results from the mechanical properties in combination with the test conditions. Cohesiveness and springiness are found to be strongly related, unless structural damage is present in the material. Adhesiveness is only an indirect measure of the adhesion between the material and compression plate and depends on the test conditions and stiffness of the material. Finite element simulations reveal a decrease of hardness in case of a nonflat top surface, indicating the importance of geometrical effects.

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.

The study was conducted to know whether bulk inflow of Non Emergency Calls (NECs) acts as an independent predictor for depression in call handlers of Rescue 1122, Punjab, Pakistan. Forty five (45) call handlers were recruited from evening shift of 9 districts. Similarly, same-sized control group was made out of field rescuers. The groups were compared for rate and severity level of depression using Beck’s Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996). Probable predictors (except workplace stress) for depression in call handlers were evaluated through risk estimates. For workplace stress, a purposefully developed close- ended Workplace Stress Questionnaire including two subscales i.e. Non Emergency call and Control Room Environment of 30 items each was administrated. Twenty nine (64.4%) subjects of study group reported depression on BDI. Consequently, the same group had significantly higher mean depression score than control (18.2 vs. 12.6; p = .00). The scores also showed insignificant association with any of the probable predictors (demographic variables) of the call attendees. The respondents perceived more occupational stress against NECs. The findings attract the attention of authorities towards the severity of the concern.
