One of the main requirements for modern technologies is to expand the range of meat products by creating combined products with a balanced composition of food and biologically active substances. The purpose of the study was to develop a technology for the production of such combined meat products. The research used secondary meat raw materials of the meat processing industry: horse meat, flank and other beef muscle tissue of the second grade, which, after fermentation by a consortium of microorganisms consisting of the following cultures: Lactobacillus bulgaricus, Bifidumbacterium siccum, Staphilococcus carnosus, were used instead of the main meat raw materials in the production of sausages. The following indicators of ready-prepared products were studied: organoleptic properties, chemical, vitamin and mineral composition, toxicity and harmlessness, storage duration. The results showed that the use of this consortium of microorganisms in the production of sausage products made it possible to use secondary collagen-containing raw materials for processing. The positive influence of the proposed biotechnological method of processing meat raw materials on the organoleptic, physical-chemical, structural-mechanical, microbiological characteristics and biological value of the finished product was revealed. It was found that the use of a consortium of microorganisms increased the quality of finished products. In addition, the proposed technology has the potential to reduce the cost of production and increase the share of waste-free production in the meat processing industry.

For the first time in the XXI century, the number of people suffering from obesity worldwide surpassed the number of undernourished people. For many developing countries, this presented a so-called "double burden" of coping for over- and under-nourishment. At a rate of more than 50% of the population in Malaysia being either overweight or obese, the country is facing the most severe dietary crisis in East Asia. Often recognized as one of the healthiest populations worldwide and having a blue zone, Japan has managed to set a yardstick for countries around Asia. Hence the purpose of this study was to uncover the capacity for contribution and successful integration of traditional vegetables into Japanese daily food practices. Semi structured interviews were conducted together with participating observation with key informants to help understand the role of women in preserving and safeguarding traditional vegetables also known as 'sansai' in terms of farming and food preparation. In order to solve the unhealthy eating patterns among Malaysians, it is timely to start appreciating the contributions of the older generation in terms of wild edible usage and preparatory methods which can help alleviate the double burden of malnutrition among the population.

Pasteurized fresh milk requires an accurate estimation of shelf life under various conditions to minimize the risk of spoilage and product losses. Milk samples were stored for 56 h in an oven at 25°C and for 15 days in a refrigerator at 4°C. Samples were analyzed using an electronic nose (e-nose), total bacterial count, titratable acidity and pH to determine the quality of milk. Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) were used to analyze e-nose data of milk stored at 25°C, and 4°C. A clear shift in quality was identified by the e-nose, which also appeared in the total bacterial count after 24 h and 12 days for storage at 25 and 4°C, respectively. On the other hand, titratable acidity exceeded the normal limits of 0.14 % - 0.21 % after 24 h for storage at 25°C (0.247 ± 0.006 %) and after 15 days for storage at 4°C (0.25 ± 0.01 %). If pH was a good indicator of quality for samples stored at 25°C, it showed no clear trends for samples stored at 4°C. Based on the microbial count data and e-nose output, the milk had a shelf life of 0.3 day (i.e. 8 h) when stored at 25°C. Shelf life was extended to 9 days when stored at 4°C.

Due to the high level of antioxidant activity of acorn fruits, they can be used as an ingredient the production of functional foods. The goal of the this research was to partially substitute wheat flour with varying levels (10% - 50% w/w) of debittered acorn flour and to investigate its effects on the rheological characteristics of the dough, total phenolic content (TPC), staling, colour indices and sensory properties of toast bread. The farinograph degree of softening and water absorption of the dough decreased with increasing the acorn flour content, while the stability and time of development of the dough increased. Resistance and extensibility to deformation of the samples respectively increased and decreased compared to those of the control. Toast bread with 30% acorn flour replacement was observed to have lower staling than the control. The highest TPC (9.44 mg GAE/g) and the lowest peroxide value (0.36 m eq O2/kg) were obtained for the bread having 30% acorn flour substitution. Moreover, the breads showed darker crumbs with significantly lower specific loaf volumes. Overall, the bread with 30% of acorn flour substitution showed good rheological, staling properties and reasonable anti-oxidant content compared to the control bread as well as the highest sensorial acceptability.

Membrane process is an intelligent alternative way of concentration, preferably for organic juices rich in thermolabile natural components. The expectation is to scale up the extraction of desired compounds from agro-industrial wastes through modernized concentration method. Recovery of betalains, phenolic, and antioxidant from beetroot peel extracts was accomplished by nanofiltration membrane (NF 200) at a recirculation flow rate (400 L h-1) and feed temperature (30 ºC) under constant transmembrane pressure (40 bar). Characterization of betaxanthin, betacyanin, phenolic, and antioxidant activity by spectrophotometric analysis revealed that the final samples contain these compounds respectively: 202.25±3.26 mg.L-1, 360.07±8.43 mg.L-1, 987.79±19.18 mg.L-1, 642.06±14.78 mg.L-1 (pure water); 206.62±1.37 mg.L-1, 339.72±2.89 mg.L-1, 972.72±47.49 mg.L-1, 745.97±25.45 mg.L-1 (ethanol-water). Final samples exhibit vivid colour and a considerably large amount of desired compounds compared to crude extracts and could have industrial applications.

Increasing consumption of instant noodles with high sodium content could elevate the risk of cardiovascular disease. Making instant noodle seasoning in the form of an oil-in-water emulsion was expected to improve the perception of salty taste without increasing the use of salt. However, the oil concentration in the emulsion affects the perception. The addition of antioxidant and retort processing was needed to overcome the nature of the emulsion that was quite susceptible to oxidation and microbial contamination. Preliminary research determined the optimum concentration of oil and antioxidant based on physical characteristics, the perception/gustation of saltiness, and emulsion oxidative stability and the results were used for further research. The final part of the research determined the effects of retort processing on emulsion stability, the perception of saltiness, and the degree of microbial contamination. Three different oil concentrations (26, 27, and 28%) and three types of antioxidants (natural vitamin E, ascorbyl palmitate and mixed tocopherol) were applied to the instant noodle seasoning oil-in-water emulsions. The results showed that using 28% oil and mixed tocopherol had the most stability, was more viscous, and had optimum salty taste perception, which significantly extended the shelf-life of the emulsion compared with the others. Retort processing for 21.5 minutes in 123.5 °C was applied to the seasoning emulsion with 28% oil content and mixed tocopherol. Although, the microbial contamination was significantly reduced, neither the stability of emulsion nor the perception of salty taste was significantly changed by the process.

Indonesian consumers are fond of commercially sterilized milk as indicated by increasing product sales. High demand for products intensifies the need to increase productivity, generally achieved by minimizing product defects. This study aimed to reduce the number of defects in commercially sterilized milk produced using overpressure rotary retorts. Based on Pareto analysis, the percentage of defective products was 5.14% of which 2.37% were dented bottles. A cause-effect diagram (Ishikawa Diagram) was used to find the root cause of dented bottles. The pressure difference between the retort chamber (external pressure) and inside the product packaging (internal pressure), and the number of bottles stacked inside the retort basket (bottle density) were found as major factors for causing dented bottles. The internal pressure was 1.20 bar higher than the external pressure. By reducing the pressure difference to 0.40 bar, the percentage of dented bottles could be reduced to 0.79%. Applying the low-est bottle density (73% of the retort basket area occupied by bottles) during the sterilization process could decrease the number of dented bottles, however, it also increased the appearance of striped lids. The best conditions for sterilization (pressure difference = 0.40 bar; number of bottles/basket = 1938 bottles) which were used in the three-month full-scale production trial reduced the percentage of defective products from 5.14% to 2.24% of which 0.76% were dented bottles. Setting the retort pressure at 2.80 bar could avoid 52,920 defective bottles of commercially sterilized products per month.

Consumption pattern among indigenous groups is usually influenced by consumers' sociocultural and perceptual factors. This study employs the binary logit model to analyse the factors that influence the consumption of sunflower oil in Kumasi, Ghana. A cross-sectional approach was used to obtain data from 200 consumers who were selected using a multi-stage sampling method. The results showed that a majority (93%) of the respondents were aware of the availability of sunflower oil on the local market and a third (69.5%) had used it for cooking before. The respondents agreed with the perception statements that sunflower oil is healthy, expensive, reduces the risk of heart diseases and cancer and has better frying performance. The empirical results of the logit regression model showed that consumption of sunflower oil is influenced by household size, awareness of the product and perceptions on health benefits, price and frying performance of sun ower oil. The price of the oil was identified as the most important constraint to its use albeit it had no negative effect on its consumption. Investments in the production and promotional strategies on the use of sunflower oil should consider the significant variables that have influence on its consumption.

Imported rice is perceived to have better cooking properties than locally grown rice in Nigeria and it has increased its market share while reducing patronage for local rice. Rice in Nigeria has many applications, including consumption as whole cooked grain or dumpling or use as an adjunct in making beverages. Eighteen varieties of parboiled milled local rice and three imported rice varieties, coded Ip1, Ip2 and Ip3, were studied for their cooking and functional properties using standard methods. There was a significant (p<0.05) increase in the dimensions of all the rice varieties when cooked. There was a 25 g increase in the grain weight and an elongation ratio of more than 1.26 in all the rice varieties. Ghesua had the highest cooked grain weight (68.67 g) while Omor-Mas (6.00) and R-Bus (6.00) had the highest volume expansion ratio (VER). The VER was more than 3.00 for all the rice varieties. All the local rice varieties imbibed less water (17.67-25.33 ml) compared to the imported rice varieties (26.00-27.67ml) before they reached their optimum cooking time. The imported rice varieties were of soft gel consistency (89.67-73.50 mm) and intermediate amylose content (20.71-23.14 %) while the local rice varied in amylose and gel consistency. Abakiliki-Mas (27.00 mm) and R-8 (33.67 mm) were of hard gel-consistency, intermediate (21.11 %) and high amylose (27.21 %) content respectively and have not been exploited although they would be appropriate for making canned rice, dry mixes and rice-noodles.

Conditions influencing Bacillus cereus growth and cereulide production, such as temperature and pH, were evaluated at varying incubation periods. The growth and cereulide production at different temperatures and pH values ranging from 10 to 40 ºC and 5.0 to 8.5, respectively showed that the temperature from 20 to 30 ºC and at pH from 6.0 to 7.0 gave the optimum growth and cereulide production by B. cereus SA105. pH below 6.0 resulted in reduced growth and cereulide production. Cereulide production increased along with the incubation period, and maximum cereulide titre (ng/mL) of 1219.1±8.90 was obtained after 6 days of incubation at 30 ºC and pH 6.5 under static conditions. There was no quantifiable toxin at incubation temperatures of 10 and 40 ºC by B. cereus SA105. This work further reveals that B. cereus growth and cereulide production was significantly affected by temperature and pH in relation to the incubation period. Furthermore, the findings of this study will serve as a means for reducing the diversity of emetic toxin-producing B. cereus population in food and food products, thus preventing food poisoning.
