Demand for innovative healthy snacks that achieve consumer satisfaction represents increased interest for competitive food producers. The aim of this work was the assessment of physicochemical and sensory quality of barley-soybean chips involving legume protein flours by studying the effects of different substitution levels (10, 20, and 30%) of defatted soybean (DSB) flour, frying temperatures (150, 170, and 190°C), and frying times (60, 90, and 120 sec). The chips’ moisture content was significantly decreased with increased frying temperature and time. The moisture content (1.40%) was achieved at 10% DSB fried at 190°C for 120 sec. The least absorbed oil (29.25%) was achieved at the least substitution percentage (10% DSB), the least frying temperature (150°C), and the least frying time (60 sec). These results were reflected on sensorial parameters that revealed that the most preferred chips were barley-soybean chips with 10% DSB fried at 150 and 170°C. The amylose content was increased by 33.80% in chips substituted with 30% DSB, while it was decreased to 27.16% in chips substituted with 10% DSB, and vice versa for the amylopectin content. TPA revealed that DSB substitution levels were directly proportional with hardness and inversely proportional with elasticity and adhesiveness. From obtained results, substitution levels with 10% DSB fried at 150°C are recommended. These findings encourage the production of innovative enhanced snacks involving legume protein while maintaining consumer satisfaction.

This work consists of studying the influence of the desamerization of the mesocarpe on the chemical composition and the sensorial quality of the jam, based on the bitter orange. The results of the various analysis show that desamerization decreases acidity, sugars, protein, and bioactive compound levels (carotenoids, polyphenols, and vitamin C), but desamerized jams still remain an important source of antioxidant compounds with antioxidant potential in the diet. Concerning the sensory analysis of the jams, the results show that the jam desamerized with water presents the same bitterness as the bitter jam and that the salt significantly reduces the bitterness of the jams.

Belgian Study

A Belgian study shows that the five most important meat attributes for the consumers are as follows: quality, taste, freshness, absence of hormones and healthiness (Verbeke and Viaene, 1999). This corroborates with the results of a French survey by Touraille (1992), who found that sensory properties and security aspects (hormones) of meat are of paramount importance for the consumer. It is important to direct pork production towards an acceptable product adapted to the consumer's demand. The objective of this study is to evaluate in which way and how strong the sensory quality parameters are influenced by different factors.

The influence of pre-fried time and temperature on the cooking yield, shear force, color and sensory quality of microwave beef kebabs were evaluated. The beef kebabs were fried for 20 s, 40 s, 60 s and 80 s at 170 ± 2 °C, 180 ± 2 °C or 190 ± 2 °C in the fryer. The results revealed that beef kebabs fried at 190 ± 2 °C for 60 s had significantly higher cooking yield, shear force, redness (a*), yellowness (b*), flavor, color and overall acceptability than the samples fried at 170 ± 2 °C and 180 ± 2 °C for 60 s. Lightness (L*), juiciness and tenderness of beef kebabs fried at 190 ± 2 °C for 60 s were lower than samples fried at 170 ± 2 °C and 180 ± 2 °C for 60 s. In addition, the cooking yield values fried at 190 ± 2 °C for different times was increased by 4.58%, 3.49%, 2.37% and 1.12% over that fried at 170 ± 2 °C. Beef kebabs fried at 190 ± 2 °C for 60 s promoted the color and cooking yield remarkably and had a beneficial effect on sensory characteristics during frying. The optimum frying parameters of kebabs were at 190 ± 2 °C of oil temperature for 60 s of frying time.

Dried smoked skipjack or better known as Katsuo-bushi is a popular type of smoked fish in Japan. It has a distinctive flavor and widely used in traditional Japanese cuisine. The weakness of commercial Katsuo-bushi nowadays is the high content of Polycyclic Aromatic Hydrocarbon (PAH) (may exceed 10 ppb).  Recent study examined the low PAH Katsuo-bushi product made with liquid smoke. However, the sensory acceptance of this product has not been determined yet.  The purpose of this study was to determine the effect of liquid smoke concentration (1%, 2% and 3%) and soaking time (10, 20 and 30 min) on the sensory quality of Katsuo-bushi. Duo-trio method was used for sensory evaluation. Additional chemical analysis such as moisture content and pH were performed. Significant differences were found among liquid smoke Katsuo-bushi product compare to traditional Katsuo-bushi (P<0.1). Also, it is suggested that the longer the soaking time, the higher the moisture content and pH value. Keyword: Katsuo-bushi, liquid smoke, Duo trio method.   Ikan kayu atau lebih dikenal dengan Katsuo-bushi adalah sejenis ikan asap yang telah lama dikenal dan memiliki flavor yang khas yang biasanya digunakan pada masakan tradisional di Jepang.  Kelemahan ikan kayu yang ada di dunia dewasa ini adalah tingginya kandungan Polycyclic Aromatic Hydrocarbon (PAH) yang melebihi 10 ppb. Penelitian terkini (Berhimpon, dkk 2016) meneliti ikan kayu asap cair yang rendah PAH, tetapi belum diteliti tingkat kesukaan secara organoleptik. Penelitian ini adalah untuk mendapatkan ikan kayu asap cair yang rendah PAH tetapi disukai oleh konsumen. Tujuan penelitian ini ialah untuk mengetahui pengaruh konsentrasi asap cair dan lama perendaman terhadap mutu organoleptik ikan kayu asap cair yang dibuat dengan berbagai konsentrasi dan lama perendaman, dan dibandingkan dengan ikan kayu konvensional. Parameter pengamatan ialah analisa organoleptik dengan metode duo trio (Berhimpon, dkk. 2005), analisa kadar air dan pH (AOAC, 2005). Hasil penelitian ini menunjukkan bahwa ikan kayu yang direndam dalam asap cair dengan konsentrasi 2% dan 3% masing-masing selama 30 dan 10 menit berbeda sangat nyata (P<0,1) dengan ikan kayu konvensional. Sedangkan perlakuan yang lain sama dengan ikan kayu konvensional. Untuk analisa kadar air dan pH menunjukkan bahwa lama perendaman memberikan pengaruh yang nyata terhadap nilai kadar air dan pH dari ikan kayu asap cair, dimana semakin lama waktu perendaman dalam larutan asap cair maka semakin tinggi kadar air dan pH dari ikan kayu tersebut. Kata Kunci: Ikan kayu (Katsuo-bushi), asap cair, metode duo trio.

Dioscorea Cayenensis

The research performed on yam processing mainly concerns the production of crisps and flour. However, its transformation into deep-frozen French fries does not necessitate any other equipment than those used for potatoes. The industrial process of production of frozen French fries traditionally includes a pre-frying step. These steps contribute to the development of color and crispness, and the oil partially absorbed inhibits dehydration during the freezing step. The aim of this study was to optimize frying conditions of deep-frozen fried yam (Dioscorea cayenensis varKponan) slices. The effect of pre-frying time and temperature, final frying time and temperature on the oil uptake, texture, dry matter and colour of the fried yam slices has been studied. Frying conditions optimized with Box-Behnken experimental design were short pre-frying and frying conditions at high temperature characterized by prefrying temperature at 157-170°C during 5-9s and frying temperature at 181-188°C for 2min 15s-2min 30s; or long pre-frying and frying conditions at low temperature characterized by pre-frying temperature at 150-158°C during 10-15s and frying temperature 170-177°C for 3-3min 15s. An adiabatic system was also developed by means of an insulator in which the core temperature of fried yam slices can be maintained constant at about 55°C after 15min of cooling, facilitating texture measurements at constant temperature. The present results may help in choosing the yam slices frying condition to be applied in order to achieve the desirable fried yam slices quality, required for protection against certain diseases like obesity. These models may also provide guidance as to how to control these quality parameters by altering four key environmental factors, pre-frying temperature and time and, final frying temperature and time. This process can also be commercialized and does not necessitate any other cost for equipment than those used for potatoes French fries and might be an interesting way of added value processing for this highly perishable yam tuber.

Chinese rolls are prepared from hot water dough and wrapped with meat and vegetable when consumption. Staling of Chinese rolls results in loss in texture and eating quality. Moisture content, enthalpy change (H), texture and sensory quality of Chinese rolls which are significantly affected during staling at 4°C storage, were monitored over a storage period of four days. Moisture content was founded to decrease steadily during staling of Chinese rolls. Enthalpy change, H, as measured by DSC increased with storage time. The texture of Chinese rolls became progressively harder with storage at 4°C. A decrease in sensory quality and acceptability of the Chinese rolls was observed with storage. Most of the staling parameters show good correlation. Texture showed the best overall correlation with all other staling parameters.
