Carcinogenic Compound

Acrylamide as a probably carcinogenic compound is known to be formed in many high thermally treated products with a natural occurrence of amino acid asparagine and reducing sugars as well. Cereal products, especially gingerbreads are extensively affected by acrylamide formation up to 1000 μg/kg and more. This study compares pros and cons of enzyme treatment and a substitution of ammonium raising agent for sodium salt addition in manufactured gingerbreads with respect to their final sensory quality. More than 97% reduction of acrylamide content was achieved by the asparaginase application before baking with no observed detrimental effect on sensory quality of final products. On the other hand, sodium raising agents efficiently decreased acrylamide content, but with no acceptable impact on colour, texture, softness, delicacy and an expected appearance of gingerbread. For that reason, the application of L-asparaginase enzyme seems to be a perspective way to mitigate acrylamide.

Sel-roti is a deep-fat fried, puffed, circular spongy doughnut like indigenous,non- alcoholic fermented cereal product of Nepal. A study was conducted to study the effect of batter ageing on physiochemical and microbial changes and its impact on sensory quality of Sel-roti.Ten samples of batters were aged for 9 h at 3 h interval at temperatures30°C, 40°C and 50°C.After ageing, acidity as lactic acid, reducing sugar and total sugar contents of the batter had increased significantly (P<0.05). The total sugar content of the batter started to decrease after 6 h of ageing. During the ageing period of 3 hour bulk density of products were decreased significantly (p<0.05) for all temperatures of ageing but after 3 hours of ageing it was increased slightly for 40°C. Fat uptake of sel-rotifound to decrease as ageing proceeds. Lactic acid bacteria, yeasts and mold co-existed in sel-rotibatter. LAB and yeast count at the end of 9 hour of aging was higher at 30°C than at 40°C. LAB and yeast count at 50°C was markedly decreased during 9 hour of ageing of batter. Mold count in the samples of batter during aging was decreased at all temperatures. Among study time and temperature of ageing quality of sel-roti prepared from batter aged at 30°C for 6 hour was found to be good in terms of sensory quality and cost effectiveness.  DOI: http://dx.doi.org/10.3126/jfstn.v8i0.11721 J.

The present work was undertaken to compare the effect of bromelain and papain on the sensory quality of sukuti (Nepalese indigenous dried buffalo meat). Buffalo lean meat (round cut) was purchased from the local market of Dharan and used for the preparation of sukuti after injection of 10% m/m enzyme (bromelain and papain) solution at the concentration (0-100 mg/L) and resting for 4h followed by drying at 65°C up to the moisture of 5%. The optimized concentration of each enzyme was selected by sensory evaluation based on color, flavor, texture, and overall acceptability. The proximate composition, collagen content, and collagen solubility were studied for two optimized samples with enzyme treatment and control. The best tenderizing effect of papain and bromelain enzyme was found at 40 mg/L and 10 mg/L respectively from the sensory analysis and the sensory attributes for these concentrations were significantly (p<0.05) higher than other samples. The soluble collagen content increased from 0.44 mg/g tissue in untreated meat to 0.52 for bromelain treated and to 0.98 mg/g for papain treated samples. The collagen solubility for the untreated sample was 4.74% which increases to 7.80% for bromelain and 13.82% for papain-treated samples. The protein content of optimized papain and bromelain treated samples was significantly decreased (p<0.05) from 82.44 to 80.25% and 81.43% respectively for papain and bromelain treated samples. There were no significant changes in fat, ash, and moisture on enzyme treatment.

AbstractBlackcurrant juices prepared with or without enzyme treatment at industrial scale were stored at room temperature or + 4 °C for 1 year, and their sensory profiles, chemical composition and rheological properties were investigated. The juice without enzyme treatment had less intense colour and it was perceived and measured as more viscose than the juice produced with enzyme assistance. Content of monomeric anthocyanins decreased significantly during storage in both juice types under both storing conditions. However, changes in colour intensity were observed only in the non-enzymatic juices. In the discrimination tests based on the appearance, the stored samples were detected as significantly different. Storage resulted in significant changes in contents of hydroxycinnamic acids and flavonols, but this did not have an impact on the bitterness or astringency of the juices. Moreover, sugar and acid contents were mainly unchanged during storage. Storage resulted in a decrease in dynamic viscosity and greater differences in viscoelastic properties for the juice with enzymatic assistance. This study provides important information about the stability of juices typically stored at room temperature for a long time.

The present investigation was carried out to study the refrigeration preservation of the cauda epididymal retrieved spermatozoa of buck in Tris egg yolk citrate (TEYC) dilutor containing pomegranate juice as antioxidant additive. The retrieved cauda epididymal spermatozoa extended in TEYC dilutor were studied in five groups by adding different concentration of pomegranate juice as additive (0% as control T1 group and 5%, 10%, 15% and 20% as treatment T2, T3, T4 and T5 groups, respectively) and storing at refrigerated temperature up to 48 hr. The results showed that the control extender had the least dead, abnormal and HOS non-reacted sperm percent among all treatments tested and that with increasing the pomegranate juice concentration in dilutor, the percentage of the dead, abnormal and HOST non-reacted spermatozoa increased significantly. The same trend was observed at all 12 hourly storage intervals indicating its detrimental effect on epididymal sperms of bucks at refrigeration temperature. The dead, abnormal, and HOST non-reacted sperm were significantly and positively interrelated with each other (r = 0.53-0.83). It was concluded that the inclusion of pomegranate juice in TEYC dilutor did not show any beneficial/antioxidant effect on epididymal sperms of buck in fresh or refrigerated semen and in fact all the levels of pomegranate juice (5% to 20%) were detrimental to cauda epididymal spermatozoa of a buck.

Type 2 diabetes has become one of the major health problems of the modern world. It is assumed that environmental factors have a significant impact on the development of the disease, and great importance is ascribed to the diet, which can be modified accordingly. The diet can exert prophylactic and therapeutic effects; changes in the diet in advanced disease can improve the quality of life of diabetic patients and minimise the risk of complications, which are the direct cause of diabetes-related death. Functional food, which has a potentially health-enhancing effect in addition to its nutritional value, has been increasingly recognised and required. Cereal products are crucial in diabetic nutrition. Their function can additionally be enhanced by fortification with compounds with proven hypoglycaemic effects. Pasta has a low glycaemic index and is a good carrier of fortifying substances; hence, it can be highly recommended in diets for diabetic patients.

Cooked Meat

An increase in the consumption of poultry meat has been observed due to its availability, nutritional value, and delicate flavor. These characteristics make it possible to prepare, with the use of spices and other additives, many different dishes and products for increasingly demanding consumers. The sous-vide technique is increasingly being used to give new sensory attributes to dishes in gastronomy. The study aimed to assess the impact of the heat treatment method, i.e., the sous-vide method, as compared to traditional cooking, on the sensory quality of poultry meat, as well as the efficiency of the process with regard to technological quality. The cooking yield with the sous-vide method of processing poultry meat was higher than with the traditional method of cooking in water (88.5% vs. 71.0%, respectively). The meat was also found to be redder (a* = 254 vs. 074) and less yellow (b* = 1512 vs. 1649), as well as more tender. The sensory quality of chicken breast meat obtained by the sous-vide method was higher in terms of attributes such as color tone, tenderness, juiciness, and overall quality. At the same time, it was lower in terms of the odor of cooked meat and the flavor of cooked meat as compared to meat subjected to traditional cooking.
