TINGKAT PENERIMAAN KONSUMEN PRODUK SOSIS KORO PEDANG DI KABUPATEN JEMBER

Sausage is a pulverized meat mixed with herbs or spices and then inserted and formed in a wrapper or casing. The ingredients used for the manufacture of sausages are meat, fat, binder, filler, water, salt and seasoning. Today has been produced sausage with non-meat raw materials, one example is by using the raw material in the form of koro pedang. Koro pedang have many advantages, one of which is to reduce the consumption of food made from raw meat. This is because the production of meat in Indonesia is low and must be imported so that the price is high, therefore used koro pedang as an alternative food made from raw meat. The purpose of this study was to determine the level of consumer acceptance of koro sosis koro pedang. The study was conducted in 3 sub-districts in Jember district, namely Patrang, Kaliwates and Sumbersari districts. The type of research used is survey method and information obtained from consumer (respondent) by using questionnaires collected from samples to represent the population which then will be used for data processing. The level of consumer acceptance of sosis koro pedang using the method of Customer Satisfaction Index (CSI) produced is 80%, which means the consumer is very satisfied.

Fruit Quality and Consumer Acceptability of Three Plum Types and 14 Plum Cultivars Grown in Maine for a Local Market

Fruit quality and consumer acceptance were measured in 14 plum cultivars. In 2015, six cultivars of asian plum (Prunus salicina) and one cultivar of american plum (Prunus americana) were harvested partially ripe and tree-ripe. In 2016, three types of plums, asian, american, and european (Prunus domestica), were harvested tree-ripe. Within most cultivars in 2015, partially ripe fruit were rated as highly as tree-ripe fruit using a hedonic rating from 1 to 9 with 1 being dislike extremely and 9 being like extremely. ‘Obilnya’ and ‘Abundance’ were rated higher than ‘Shiro’ and ‘Methley’ at both stages of ripeness and higher than ‘Vanier’ at the partially ripe stage. ‘Early Golden’ and ‘Spring Satin’ were rated higher than ‘Shiro’ and ‘Methley’ at the tree-ripe stage. In 2016, seven cultivars (Obilnya, Kahinta, Superior, Toka, Castleton, Early Italian, and Rosy Gage) were scored at the desired consumer acceptance level. ‘Shiro’ and ‘Caçak’s Best’ received overall acceptability scores below the level of acceptability. Plum type had minimal effect on scores for texture, sweetness, sourness, and overall liking. European cultivars received lower color scores than american and asian plums. Soluble solids concentration (SSC) ranged from 6.7% to 13.6% in asian plums, from 14.8% to 19.8% in american plums, and from 15.3% to 22.1% in european plums. Overall consumer acceptance of american and european cultivars was as good as for asian cultivars.

PENGENALAN PENGOLAHAN SUSU KAMBING DI KECAMATAN SUKADANA KABUPATEN LAMPUNG TIMUR [Introduction of Goat Milk Processing in Sub-district of Sukadana, District of East Lampung of the Lampung Province

Milk is easily damaged when handling is poor, so it has a relatively short shelf life. To handle the excess milk production, the most appropriate step is to preserve milk to extend the shelf life through processing, and at the community level the consumption of processed milk is higher than the consumption of fresh milk. This research was conducted in Muara Jaya Village, Sukadana District, East Lampung Regency, from June to August 2016 with Mentari’s women farmer group as cooperator. The types of processed goat milk introduced are goat’s milk with spice flavoured, goat's milk ice cream with strawberry tasted, goat's milk ice cream with kweni tasted, and goat's milk caramel candy. The products of goat’s milk are tested on consumer preference and its counted breakeven price for each kind of product, so it is known how much the price of kind of processed goat’s milk if it want to commercialized. Observation parameters included, proximate analysis for fresh goat’s milk, consumer acceptance rate and break even price of each kind of product. Observation of consumer acceptance level is done by using hedonic scale (scale 1-5) from 20 panelists and breakeven price is calculated by comparing total production cost with yield produced. The collected data were analyzed statistically and if there was difference of the mean value was continued with DMRT test at 5% level. The results showed that the development of goat’s milk preparation is very pospective because goat’s milk has high protein content and low fat content so good for health; Processed goat’s milk produced introduced by the consumer, with a mean score> 3; The result of break even analysis shows that goat milk processing has prospect to be developed, because the price of its break even point is still reached by consumer that is: Rp.45.500, -/ liter goat’s milk spice flavoured; Rp. 61.267/liter goat's milk ice cream strawberry tasted, Rp.55.933, -/ liter goat's milk ice cream kweni tasted, and Rp. 1.479 /goat's milk caramel candy.

Consumer Attitudes on Salt and Fat Reduced Foods in the Republic of Ireland

Public health campaigns are continually promoting healthier foods and in parallel many food manufacturers are working on recipes low in fat and salt. The following survey investigates how well consumers (n = 1045) in Ireland have assimilated the message of consuming healthier foods, including salt and fat reduced foods, into their diet. It seems that campaigns regarding the importance of a balanced diet have generally been adopted by respondents, as only a minority of the participants did not take care of their diet, independent of age, gender and level of education. More than half of the participants carefully maintained a balanced diet. Furthermore, an increase in purchasing salt reduced food was observed, though fat reduced food products were already better accepted. In general, men, young adults (<30 years) and lower educated people purchased less salt and fat reduced foods and took less care in maintaining a balanced diet. No conflict was observed for traditional foods reduced in salt and fat content when their intrinsic sensory character is maintained. The majority of the participants were aware of the health risks of a diet rich in salt and fat, though less participants transferred this knowledge into their diet. A very high demand for more salt and fat reduced foods on the market was observed although the smaller range of salt and fat reduced products and their higher prices might diminish the level of consumer acceptance. Launching taxation and subsidies in tandem might counteract this and furthermore, user-friendly product labelling schemes are required.

Aplikasi Nano Emulsi Minyak Serat Sawit sebagai Pewarna Alami dan Sebagai Sumber Karotenoid pada Mi Basah Pasta Pisang Awak (Musa Paradisiaca Var.Awak)

The attractive colors and colors derived from natural pigments are very much favored by consumers, as natural pigments in addition to being dyes also serve as a source of vitamins. The aims of this study were to determine the effect of the amount of nanoemulsion applied and storage duration on the color of wet banana noodles and the potential of wet noodles as a source of carotenoids and to increase the level of consumer acceptance of the color of wet noodles. The research used complete Random Design (RAL) factorial where first factor was the amount of nanoemulsion consisted of 3 levels namely: 0%, 3% and 6%. Second factor was storage duration consists of 3 levels :0 days, 3 days, and 6 days. Each treatment with three replications. The results showed that the color of wet noodles ranged from yellowish to yellow. The intensity of the yellow color decreased during the storage process. The 3% nanoemulsion applied on wet noodles potentially suffice 4.4% of the vitamin A requirement and its potency decreased to 2.6% after the noodles were stored for 6 days. While noodles applied 9% nanoemulsion on noodle was potentialto suffici vitamin A by 10,4% from requirement of vitamin A, but decrease to 4.3% after wet noodles were kept for 6 days. The storage duration gave no significant effect on the color preference test but the nanoemulsion application increased thelevel of panelist's preference on wet noodles color from 2.2 (dislikes) to 4.05 (like).

The Effect of Origin, Sex and Feeding on Sensory Evaluation and Some Quality Characteristics of Goose Meat from Polish Native Flocks

Abstract The aim of the study was to characterize the sensory quality and physical traits of raw and heattreated meat depending on the origin, sex and feeding of geese. The experiment used meat from domestic geese of southern varieties: Lubelska (Lu), Kielecka (Ki) and Subcarpatian (Sb), included in the conservation programme. The experiment was carried out on a total of 192 birds divided according to origin (Lu, Ki and Sb), sex (M and F) and dietary treatment (DI – conventional feeding and DI – oat fattening). To evaluate the quality characteristics of meat, 16 birds from each group were selected. Sensory evaluation of raw goose muscles was at a good level of consumer acceptability and exceeded 4.0 points, ranging from 4.18 pts (appearance/Ki) to 4.59 pts (aroma/Sb) for breast muscles (BM), and from 4.17 pts (fatness/Lu) to 4.53 pts (aroma/Sb) for leg muscles (LM). In the case of heat-treated muscles the tenderness of the muscles of Lu geese was characterized by high number grade (P≤0.05) for both the BM (4.87 pts) and LM (4.76 pts). Lighter colour (L*) (P≤0.05) was characteristic of the muscles of oat-fattened birds (44.25 for BM and 49.86 for LM) compared to the muscles of conventionally fed birds (39.77 for BM and 46.89 for LM). In addition, a significant (P≤0.05) effect of diet was also found on the value of the parameter a* (redness) and b* (yellowness). Parameter a* ranged from 10.45 (Lu) to 11.96 (Ki) for BM and from 13.28 (Ki) to 14.21 (Sb) for LM. In turn, the highest share (P≤0.05) of yellow colour (parameter b*) was demonstrated in the muscles of Ki geese – 4.87 for BM and 10.92 for LM. Male muscles were characterized by higher (26.34 mg% – BM and 24.37 mg% – LM) water holding capacity (WHC) than female muscles (27.23 mg% for BM and 25.28 mg% for LM respectively). Furthermore for BM of oat-fattened geese cooking loss was at the level of 10.50%. The present study indicated that most of the sensory characteristics of meat (BM and LM) from geese of different breeds were affected (significantly at P≤0.05) by the diet. This concerned both raw and heat-treated meat. For raw breast muscles, a significant (P≤0.05) effect of sex was also found (with the exception of aroma). In turn, the quality characteristics of raw leg muscles (except for colour) were influenced (P≤0.05) by all the treatment factors. Analysis of the physical properties of meat showed that these parameters are mainly affected (P≤0.05) by the diet.

Future Protein Supply and Demand: Strategies and Factors Influencing a Sustainable Equilibrium.

A growing global population, combined with factors such as changing socio-demographics, will place increased pressure on the world’s resources to provide not only more but also different types of food. Increased demand for animal-based protein in particular is expected to have a negative environmental impact, generating greenhouse gas emissions, requiring more water and more land. Addressing this “perfect storm” will necessitate more sustainable production of existing sources of protein as well as alternative sources for direct human consumption. This paper outlines some potential demand scenarios and provides an overview of selected existing and novel protein sources in terms of their potential to sustainably deliver protein for the future, considering drivers and challenges relating to nutritional, environmental, and technological and market/consumer domains. It concludes that different factors influence the potential of existing and novel sources. Existing protein sources are primarily hindered by their negative environmental impacts with some concerns around health. However, they offer social and economic benefits, and have a high level of consumer acceptance. Furthermore, recent research emphasizes the role of livestock as part of the solution to greenhouse gas emissions, and indicates that animal-based protein has an important role as part of a sustainable diet and as a contributor to food security. Novel proteins require the development of new value chains, and attention to issues such as production costs, food safety, scalability and consumer acceptance. Furthermore, positive environmental impacts cannot be assumed with novel protein sources and care must be taken to ensure that comparisons between novel and existing protein sources are valid. Greater alignment of political forces, and the involvement of wider stakeholders in a governance role, as well as development/commercialization role, is required to address both sources of protein and ensure food security.

Australia's coastal fisheries and farmed seafood: an ecological basis for determining sustainability

In response to consumer concerns about the sustainability of Australian-sourced seafood we derive a set of criteria within an explicit decision-process that can be used to determine whether locally farmed and wild-caught Australian seafood products meet standards of ecological sustainability and Ecologically Sustainable Development. These criteria substantially address the ecological deficiencies we identified in other systems commonly used for assessing seafood sustainability. The criteria address the issues that are relevant to local seafood production, and are populated with indicators (metrics) and benchmarks relevant to the Australian context. The indicators establish performance thresholds drawn from public domain data about the products, including observed empirical data and proxies, and include default decisions to be applied in the absence of adequate information. This decision structure is set within a peer-reviewed expert jury decision-making process. The criteria, decision process and decision outcomes from assessment of a number of pilot products were tested in a real seafood market (Melbourne), where we found a high level of producer, reseller and consumer acceptance of the judgements and ratings. The use of ecologically-derived standards results in several outcomes that differ from those of other seafood assessment systems, especially those assessments more focused on production standards, such as government, industry and NGO-supported programs, popularly used in Australia and worldwide. We conclude that despite high levels of uncertainty surrounding many of the population parameters, ecological patterns and processes, empirical cost-effective proxies can be used to reasonably estimate a form of sustainability that matches consumer interests/expectations for production of fresh local seafood. Despite the plethora of industry and government programs, there remains a significant but presently unmet consumer demand for ecologically-based, technically robust, independently derived, and readily available information about the local sustainability attributes of Australian wild-caught and farmed fresh seafood.

Karakteristik Kimia dan Organoleptik Rumput Laut (Eucheuma cottonii) Fermentasi dengan Perbedaan Lama Waktu Fermentasi dan Jenis Gula

The purpose of this research was to determine the effect of different fermentation time and the type of sugar to the chemical, organoleptic characteristics of fermented seaweed and consumer acceptance level by looking at the level of preference for the product. The research method in this study used a factorial randomized block design (RAKF) with two treatments factor and repeated twice. The first factor was time ot the fermentation (W0 (zero hour), W1 (24 hours), W2 (48 hours) and W3 (72 hours)) and the second factor was the type sugar (G0 (without sugar), GP (sugar), GA (palm sugar) and GK (coconut sugar)). The parameters of observation were ash content, lactic acid, pH range, dietary fiber and organoleptic (appearance, color, odor, texture and taste). The results showed that the treatments difference of fermentation time dan sugar on the fermented seaweed product was significant for all the treatments. The best treatment based on chemical and sensory analysis were product with addition of sugar and 48 hours fermentation time.

Minimization of Antinutrients in Idli by Using Response Surface Process Optimization

Deploying response surface methodology, the stages of idli preparation were optimized for minimizing the level of antinutrients. Under optimum conditions of soaking blackgram dal (1:5 of dal and water at 16C, and pH 4.0 for 18 h) and rice (1:5 of rice and water at 16C, and pH 5.6 for 18 h), the tannins content, trypsin inhibitor activity and hemagglutinating activity reduced, while phytic acid content remained unchanged. The optimum conditions for fermentation of dal-rice (1:2) mixed batter were 16 g/kg common salt supplementation and 19 h at 35C, resulting in a decrease in all the antinutrient levels, except amines. Steaming for an optimized period of 20 min further reduced the phytic acid content and trypsin inhibitor activity. In idli, while total biogenic amines content increased by 339% over raw ingredients, tannins content, phytic acid content, trypsin inhibitor activity and hemagglutinating activity decreased by 100, 89, 58 and 100%, respectively. Practical Applications: For idli preparation, the optimization of processing stages using response surface methodology significantly minimized the level of antinutrients from both blackgram dal and rice without affecting the organoleptic attributes of the product. The optimized process parameters can be applied to household level and are also useful in scaling up idli production with a minimum level of antinutrients and better consumer acceptability. The outcome of this research can be exploited to other legume-based foods as well, particularly in developing regions where the consequences of antinutrients may exacerbate malnutrition and disease, thus effectively utilizing full potential of the legumes as human and animal foods.

Effect of Blanching on Saponins and Nutritional Content of Moringa Leaves Extract

Moringa &lt;em&gt;oleifera&lt;/em&gt; leaves have been used as food material because it has high nutritional value. Many research have been conducted on moringa leaves extract as functional food and the additional material of nutrient for some food products (biscuit, bread, jelly drink), which it looked that adding moringa leaves extract above 5% decrease the consumer acceptance level toward the product because of the strongest unpleasant aroma and bitter taste, which is caused by saponins content in moringa leaves extract is still high enough. The aim of the research is to determine the optimum time and temperature of blanching process of moringa leaves in order to decrease its saponin content and at the same time to preserve its nutritional content. Blanching process used temperature 85 ˚C for 7.5 minutes can decrease saponins content of moringa leaves to the lowest content amount 3.9 %, but still preserve protein content amount 25.08 %, vitamin C content amount 84.68 mg 100g-1 and increase vitamin A amount 3600 μg 100g-1.

Sensory and Physico‐Chemical Properties of Cold Press‐Produced Tomato (Lycopersicon esculentum L.) Seed Oils

AbstractIn this study, roasted and unroasted (control) tomato seeds were cold pressed and the seeds, oils, and seed presscakes (meals) were analyzed. Some physicochemical properties, total phenolic content and antioxidant capacity, thermal properties, mineral contents, fatty acids, sterols and tocopherols compositions, volatile compounds and sensory evaluation of the tomato seed oils were determined. The tomato seeds contained 3.3 % of ash, 17.3 % of oil and 27.2 % of protein. The cold press oil recovery rate was 7.2 and 10.28 % for control and roasted seeds, respectively. There were eight sensory terms defining the oils together with 34 different aromatic compounds quantified. The volatile compounds furfural, hexanal, benzaldehyde and 2‐isobutylthiazole were found with the highest frequency in the samples. Roasted, green and tomato were defined as characteristic sensory terms for tomato seeds oils. Fifteen different minerals, melting and crystallization temperatures and enthalpies of the oil samples were also quantified. This study provides important data for the tomato seed oils, and proves that pre‐roasted tomato seed oils are high quality, nutritious and aromatics oils with higher levels of consumer acceptability.
