Sensory acceptability of raw and extruded bovine rumen protein in processed meat products

The use of bovine rumen protein (raw and extruded) as a replacement for extruded soy protein concentrate in three meat products (pork sausage, chicken hamburger, and kibbe) was investigated. Similarity between rumen and soy protein meat products was assessed using triangle tests and sensory acceptability evaluated by consumer panelists using a nine-point hedonic scale. The addition of raw rumen protein was detected in all meat product types tested, while extruded rumen protein was only detected in kibbe. The addition of raw rumen protein decreased the acceptability of pork sausage aroma and flavor, but improved kibbe appearance, texture and overall acceptability. The addition of extruded rumen protein reduced the acceptability of chicken hamburger texture, but improved pork sausage flavor. Replacement of soy protein by bovine rumen protein is feasible based upon sensory results, but depended upon its form and the type of meat product to which it was added. (C) 2011 Elsevier Ltd.

Women's acceptability of misoprostol treatment for incomplete abortion by midwives and physicians : secondary outcome analysis from a randomized controlled equivalence trial at district level in Uganda

OBJECTIVE: This study aimed to assess women´s acceptability of diagnosis and treatment of incomplete abortion with misoprostol by midwives, compared with physicians. METHODS: This was an analysis of secondary outcomes from a multi-centre randomized controlled equivalence trial at district level in Uganda. Women with first trimester incomplete abortion were randomly allocated to clinical assessment and treatment with misoprostol by a physician or a midwife. The randomisation (1:1) was done in blocks of 12 and stratified for health care facility. Acceptability was measured in expectations and satisfaction at a follow up visit 14-28 days following treatment. Analysis of women's overall acceptability was done using a generalized linear mixed-effects model with an equivalence range of -4% to 4%. The study was not masked. The trial is registered at ClinicalTrials.org, NCT 01844024. RESULTS: From April 2013 to June 2014, 1108 women were assessed for eligibility of which 1010 were randomized (506 to midwife and 504 to physician). 953 women were successfully followed up and included in the acceptability analysis. 95% (904) of the participants found the treatment satisfactory and overall acceptability was found to be equivalent between the two study groups. Treatment failure, not feeling calm and safe following treatment, experiencing severe abdominal pain or heavy bleeding following treatment, were significantly associated with non-satisfaction. No serious adverse events were recorded. CONCLUSIONS: Treatment of incomplete abortion with misoprostol by midwives and physician was highly, and equally, acceptable to women. TRIAL REGISTRATION: ClinicalTrials.gov NCT01844024.

Acceptability of home-assessment post medical abortion and medical abortion in a low-resource setting in Rajasthan, India : Secondary outcome analysis of a non-inferiority randomized controlled trial

Background: Studies evaluating acceptability of simplified follow-up after medical abortion have focused on high-resource or urban settings where telephones, road connections, and modes of transport are available and where women have formal education. Objective: To investigate women's acceptability of home-assessment of abortion and whether acceptability of medical abortion differs by in-clinic or home-assessment of abortion outcome in a low-resource setting in India. Design: Secondary outcome of a randomised, controlled, non-inferiority trial. Setting Outpatient primary health care clinics in rural and urban Rajasthan, India. Population: Women were eligible if they sought abortion with a gestation up to 9 weeks, lived within defined study area and agreed to follow-up. Women were ineligible if they had known contraindications to medical abortion, haemoglobin < 85mg/l and were below 18 years. Methods: Abortion outcome assessment through routine clinic follow-up by a doctor was compared with home-assessment using a low-sensitivity pregnancy test and a pictorial instruction sheet. A computerized random number generator generated the randomisation sequence (1: 1) in blocks of six. Research assistants randomly allocated eligible women who opted for medical abortion (mifepristone and misoprostol), using opaque sealed envelopes. Blinding during outcome assessment was not possible. Main outcome measures: Women's acceptability of home-assessment was measured as future preference of follow-up. Overall satisfaction, expectations, and comparison with previous abortion experiences were compared between study groups. Results: 731 women were randomized to the clinic follow-up group (n = 353) or home-assessment group (n = 378). 623 (85%) women were successfully followed up, of those 597 (96%) were satisfied and 592 (95%) found the abortion better or as expected, with no difference between study groups. The majority, 355 (57%) women, preferred home-assessment in the event of a future abortion. Significantly more women, 284 (82%), in the home-assessment group preferred home-assessment in the future, as compared with 188 (70%) of women in the clinic follow-up group, who preferred clinic follow-up in the future (p < 0.001). Conclusion: Home-assessment is highly acceptable among women in low-resource, and rural, settings. The choice to follow-up an early medical abortion according to women's preference should be offered to foster women's reproductive autonomy.

Assessing feasibility and acceptability of study procedures : getting ready for implementation of national stroke guidelines in out-patient health care

BACKGROUND: Even though Swedish national guidelines for stroke care (SNGSC) have been accessible for nearly a decade access to stroke rehabilitation in out-patient health care vary considerably. In order to aid future interventions studies for implementation of SNGSC, this study assessed the feasibility and acceptability of study procedures including analysis of the context in out-patient health care settings. METHODS: The feasibility and acceptability of recruitment, observations and interviews with managers, staff and patients were assessed, as well as the feasibility of surveying health care records. RESULTS: To identify patients from the the hospitals was feasible but not from out-patient care where a need to relieve clinical staff of the recruitment process was identified. Assessing adherence to guidelines and standardized evaluations of patient outcomes through health care records was found to be feasible and suitable assessment tools to evaluate patient outcome were identified. Interviews were found to be a feasible and acceptable tool to survey the context of the health care setting. CONCLUSION: In this feasibility study a variety of qualitative and quantitative data collection procedures and measures were tested. The results indicate what can be used as a set of feasible and acceptable data collection procedures and suitable measures for studying implementation of stroke guidelines in an out-patient health care context.

Effect of fat replacement by insulin or lupin-kernal fibre on sausage patty acceptability, post-meal perceptions of satiety and food intake in men

The present study examined whether replacing fat with inulin or lupin-kernel fibre influenced palatability, perceptions of satiety, and food intake in thirty-three healthy men (mean age 52 years, BMI 27·4 kg/m²), using a within-subject design. On separate occasions, after fasting overnight, the participants consumed a breakfast consisting primarily of either a full-fat sausage patty (FFP) or a reduced-fat patty containing inulin (INP) or lupin-kernel fibre (LKP). Breakfast variants were alike in mass, protein and carbohydrate content; however the INP and LKP breakfasts were 36 and 37 % lower in fat and 15 and 17 % lower in energy density respectively compared with the FFP breakfast. The participants rated their satiety before breakfast then evaluated patty acceptability. Satiety was rated immediately after consuming the breakfast, then over the subsequent 4·5 h whilst fasting. Food consumed until the end of the following day was recorded. All patties were rated above ‘neither acceptable or unacceptable’, however the INP rated lower for general acceptability (P=0·039) and the LKP lower for flavour (P=0·023) than the FFP. The LKP breakfast rated more satiating than the INP (P=0·010) and FFP (P=0·016) breakfasts. Total fat intake was 18 g lower on the day of the INP (P=0·035) and 26 g lower on the day of the LKP breakfast (P=0·013) than the FFP breakfast day. Energy intake was lower (1521 kJ) only on the day of the INP breakfast (P=0·039). Both inulin and lupin-kernel fibre appear to have potential as fat replacers in meat products and for reducing fat and energy intake in men.

Sensory acceptability of foods containing Australian sweet lupin (Lupinus angustifolius) flour

Foods containing Australian sweet lupin (Lupinus angustifolius) flour (ASLF) were assessed by consumer panelists (n= 54) in comparison to wheat flour (control) and defatted soy flour (DFSF) products. All ASLF products were rated in the acceptable half of the evaluation scale. General acceptability of ASLF chocolate chip cookies and breakfast bars was rated similarly to the control and DFSF variants (P > 0.05). ASLF pasta was rated lower than control but higher than DFSF pasta (P < 0.05), whereas ASLF addition reduced the general acceptability of muffins and bread (P < 0.05) compared with the other variants. Some ASLF products appeared palatable whereas ASLF incorporation rate in others requires reduction.

Consumer acceptability of low fat foods containing inulin and oligofructose

Inulin and oligofructose were used as fat replacers in Anzac cookies, blueberry muffins, carrot cake, chocolate cake, lemon cheesecake, ice cream, and beef sausages at levels ranging from 4 to 13g/100g, achieving a significant reduction in fat content (20% to 80% relative). These foods were rated as acceptable by an untrained taste panel, but scored consistently lower than their full-fat counterparts (controls). Regression analysis showed that, unlike the controls, texture was more important than flavor in determining overall acceptability of the low-fat foods. Inulin and oligofructose are readily incorporated into bakery and meat formulations, but their use might be limited by adverse physiological effects when consumed at high levels.

Exploring the feasibility and acceptability of using internet technology to promote physical activity within a defined community

ISSUE ADDRESSED: To explore the feasibility of using the Internet and e-mail to promote physical activity in a defined community.

METHODS: An online survey was conducted through a community-based Internet Service Provider (ISP). ISP clients were recruited via electronic newsletter and direct e-mail. Data were collected on preferred sources of assistance for physical activity advice and stage of motivational readiness for physical activity.

RESULTS: Valid surveys were completed by 797 (9% response rate). Participants were: 55% men; 56% aged >45 years; 57% worked full time; mean BMI was 28+/-8. Thirty-six per cent were in the early stages of motivational readiness for physical activity. More than 70% were somewhat to extremely interested in having access to a physical activity website.

CONCLUSION: Promoting physical activity via the Internet and e-mail is feasible and appealing to some people. Expanding the reach, appeal and use of this technology to deliver physical activity programs will be a challenge.

Extruded products with Fenugreek (Trigonella foenum-graecium) chickpea and rice: Physical properties, sensory acceptability and glycaemic index

The present study investigated the effects of fenugreek flour (Trigonella foenum-graecum) and debittered fenugreek polysaccharide (FenuLife^®) inclusion on the physical and sensory quality characteristics, and glycaemic index (GI) of chickpea–rice based extruded products. Based on preliminary evaluation with different proportions of chick pea and rice, a blend of 70:30 chickpea and rice was chosen as the control for further studies. The control blend, replaced with fenugreek flour at 2%, 5% and 10%, or fenugreek polysaccharide at 5%, 10%, 15% and 20%, was extruded at the optimum processing conditions as specified in the detailed study. The extruded products were evaluated for their physical (moisture retention, expansion, hardness, water solubility index (WSI) and water absorption index (WAI)), sensory (flavor, texture, color and overall acceptability) characteristics and in vitro GI to evaluate their suitability as extruded snack products.

Due to the distinct bitter taste, inclusion of fenugreek flour was not acceptable at levels more than 2% in extruded chickpea based products. Addition of fenugreek polysaccharide resulted in slight reduction in radial expansion (P < 0.05), while longitudinal expansion increased. WAI increased while WSI decreased compared to the control (P < 0.05). The mean scores of sensory evaluation indicated that all products containing fenugreek polysaccharide up to 15% were within the acceptable range. There were no significant differences (P > 0.05) between products containing 5–15% fenugreek polysaccharide in their color, flavor, texture and overall quality.

Fenugreek, in the form of debittered polysaccharide (FenuLife^®) could be incorporated up to a level of 15% in a chickpea–rice blend to develop snack products of acceptable physical and sensory properties with low GI Index.

Chemical modification of timber decking : assessing the parameters of acceptability

The criteria for accepting or rejecting a technology extend beyond the intrinsic properties of the finished product such as physical performance. There are also extrinsic factors such as the history of the product and trust in the manufacturers and suppliers, as well as the perceptions and risk management strategies of various stakeholder groups. A methodology was trialled to take into account the extended supply chain of the product, while simultaneously engaging stakeholders to determine and to understand their perceptual frameworks. Three pine decking products manufactured using different amounts and types of chemical modification were compared using life cycle assessment and the comments of 114 respondents from six stakeholder groups in New Zealand. The results of the perceptual research include a quadrant diagram which allows a visual comparison of the responses of different stakeholders to actual or hypothetical products, aiding the identification of when and why certain technologies may be disqualified from acceptability or become the topic of public debate.

Acceptability, impact and sustainability of the national pilot quality assurance system for self management programs

Chronic condition self-management education and training interventions such as the Stanford Self Management Programs (SMP) have the capacity to improve health and quality of life of people with chronic conditions whilst reducing the use of health services. This is in line with the outcomes from the recent Council of Australian Governments’ meeting where it was indicated that self-management will be a centrepiece in forthcoming chronic disease initiatives.
Aim: report on a large national pilot quality assurance program involving the implementation and of an evaluation and quality monitoring system for SMPs including the provision of structured feedback to courses course leaders and service providers. During 2005/06 the quality assurance program was implemented at 11 diverse organisations across Australia. The program involved assisting organisations apply the 42-item Health Education Impact Questionnaire (HEIQ), a chronic disease health education outcome measure, and then observe and evaluate the value and impact of the quality program. Interviews with course leaders (n=60) and course participants (n=35) have elicited views about course quality and feedback processes.
Results: The evaluation revealed enablers and barriers to effective implementation and sustainability. Important enablers were:
- Course Leaders and organisations valued an Australia-wide system that provided feedback on course
quality and the impact on participants.
- Course Leaders were strongly personally motivated to respond appropriately to HEI-Q course
report feedback.
- Completing the questionnaire provided participants with the opportunity to reflect on issues that
emerge in the course content and reflect on their progression at the end of the SSMP.
Sustainability issues included:
- Organisations and course leaders require support, training and flexibility on how to administer and
manage the use of the HEI-Q.
- Availability of administrative resources in organisations to support the quality assurance activities.
- The requirement that course leaders are trained in interpreting HEI-Q course report data.
A quality improvement framework was developed which identified the actions required of key stakeholders to
support effective implementation.
Discussion: With the increasing endorsement of SMP across sectors it is important that course quality is known, is acceptable, and is communicated to stakeholders to inform and engender confidence in the SSMP. To effectively implement and sustain a quality improvement program for SMP, the processes and tools for measuring outcomes need to be responsive, flexible and easily integrated into the organisation and delivery of programs.
