Background: Under nutrition is a condition due to insufficient intake of energy and nutrients to meet an individual’s needs to maintain good health. Cereals and millets based supplementary foods represents good source of essential nutrients. Recently, millets are tagged as nutri-cereals and its health promoting benefits are attracting consumers worldwide. The current study was aimed to develop millet based ready-to-use composite mix and to evaluate its quality in terms of usage in various traditional foods and shelf life. Methods: RTU composite mix was developed using locally available cereals, millets, pulses and oilseeds. The nutrient composition of developed mix was analyzed. The traditional region specific foods namely Dose, roti and Mudde (Ragi ball) was prepared and subjected for sensory evaluation. Further mix was stored up to three months at room temperature and evaluated for microbial load, moisture, free fatty acid and peroxide value. Result: Protein, fat, carbohydrate and energy content of the mix were 18.5g, 9.56g, 58.21g and 393.24 kcal per 100 g respectively. Roti was best accepted (7.63), followed by mudde (7.50) and dose (7.03). Free Fatty Acid (FFA) was increased from 1.08 per cent to 1.56 per cent oleic acid, whereas peroxide value (PV) was increased from 7.46 to 9.35 mEq O2/ Kg of oil during storage. Total bacterial count (TBC) was increased from 4.5 X 102 to 8.1 X 103. The developed RTU mix which has nutritional potential needs to be popularized to address under nutrition and for overall good health of the society.

Melon Seed Oil

The physical value of oil depends upon its chemical composition, even today these values play a vital role while using different oil for industrial products and also, despite the vast nutritional and medicinal significance of egusi melon, there are little details on the shell life and stability of its oil over time. Therefore, the influence of time and temperature on melon seed oil was investigated at temperatures of 0oC and 30oC at different weeks to ascertain its physicochemical value and storage stability. For week zero, at 0oC and ambient temperature (30oC), the result revealed iodine value 124.09, Acid value 3.64 mgNaOH/g, Free Fatty Acid value 1.84 mgNaOH/g, Saponification 217.35 mgKOH/g, Peroxide value 1.25 mg/g oil, pH 5.89 and thiobarbituric acid value 0.1383 respectively. In the 5th week, at 30oC, the result revealed iodine value 91.1543, acid value 12.8921 mgNaOH/g, free fatty acid value 6.4988 mgNaOH/g, Saponification 346.42 mgKOH/g, Peroxide value 9.5mg/g oil, pH 3.2 and thiobarbituric acid value 0.413 respectively. Also at 0oC in the 5th week, the results were observed as follow: Iodine value 102.53, Acid value 7.96 mgNaOH/g, Free Fatty Acid value 4.01 mgNaOH/g, saponification 287.51 mgKOH/g, Peroxide value 6.1 mg/g oil, pH 5.05, and thiobarbituric acid value 0.2658 respectively. Refrigeration (0oC) of oil reduced the rate of most of the oxidative deterioration that produces rancidity. These values are within recommended range for edible oils. These results indicate that egusi melon oil could be a good source of table oil. The statistical results show that there was a significant difference between the melon seed oil stored at 0oC and 30oC (P < 0.001).

The effect of microwave heating as a thawing method on physical, chemical sensory, and microbiological properties of frozen chicken was investigated in comparison with other thawing methods (at ambient temperature, in refrigerator, and in running tap water). Microwave thawed chicken had the highest taste panel scores and the lowest drip percentage loss compared with the other thawing methods. Thiobarbituric acid value (TBA) remarkably increased the samples thawed at ambient temperature or under running water. The data revealed that the retention of thiamin was the highest in the microwave thawed samples (97.33%), and the lowest in running water thawed samples (66.66%). The total bacterial count in frozen chicken remarkably decreased as a result of microwave thawing treatment while increased in the other treatments.

Whole-hog sausage was prepared from hot- and cold-boned pork raw materials to determine the effects of meat type, storage temperature and length of storage on various processing and bacteriological characteristics. Samples were stored at −1 and 4°C for 0, 28 and 56 d. Various physical, chemical and microbiological properties of the sausage were evaluated. Thiobarbituric acid (TBA) values were not affected by meat type (pre or postrigor). Hunter-Color values varied significantly among the meat types and storage temperatures. Total bacterial counts varied significantly among the hot- and cold-boned pork sausage samples (day 0). Cold-boned sausage stored at −1°C had lower plate counts of the various treatments for days 28 and 56. Pseudomonas was the predominant organism found in hotand cold-boned sausage samples. Hot-boned sausage exhibited a more diverse bacterial population than did cold-boned sausage. More gram-positive organisms were found in hot-boned sausage samples. Cold-boned sausage had a lower total bacterial count at day 0 and maintained lower counts and therefore a longer shelf life throughout the study when held at −1°C.

This study investigated the effect of different detergents used to clean cows' udders on the microbial content of the produced milk using twenty cows in Ajloun, a northern city in Jordan. The milking process was repeated from same cows on three successive days. On day 1, we milked the cows after cleaning their udders using water only. This was repeated on the two successive days. Thereafter, the cows were milked after cleaning their udders by a different detergent each day. The process was also repeated for three successive days for each detergent. Microbial Analysis was carried out on the collected milk samples. The results indicated that cleaning cows' udders before milking has improved the hygiene conditions and reduced the total bacterial count, total coliform, staphylococci and enterococci spp counts and the values of yeast and molds. Different detergents had different effects on the microbial counts. Finally, the effectiveness of the detergent differed according to its brand. Our findings are important to public health because milk has been a traditional food and ironically a very potent carrier of gastrointestinal infections, if contaminated.

Vacuum Frying

Chub mackerel (CM) is a commercial fish in Korea, owing to its availability and nutritional values. This study aimed to develop a ready-to-heat (RTH) Korean preparation of CM, known as Godeungo gangjeong. We utilized vacuum frying technology to fry the CM and evaluated its quality. Conventional frying with a deep fryer was performed in parallel to assess the superiority of the vacuum fryer. We optimized the frying conditions of vacuum frying (VBF) and deep frying (DBF) using response surface methodology. At optimum conditions of 95 °C for 7 min 42 s, VBF produced better sensory, chemical, and microbial properties than DBF at 190 °C for 5 min 30 s. The nutritional values, including amino acid and fatty acid contents, were investigated and found to be higher in VBF than in DBF. Sensory properties also showed better scores on VBF than DBF, especially in appearance, aroma, taste, and overall acceptability. The VBF produced lower volatile basic nitrogen (VBN), thiobarbituric acid reactive substances (TBARS), and total bacterial count (TBC) than DBF. The findings confirmed that vacuum frying is a better option to produce RTH Godeungo gangjeong, since it provides less oxidation and maintains the product quality. Using the Arrhenius approach, the product was concluded to preserve both quality and safety for 9 months of storage at −18 °C.

This study was carried out to evaluate the quality of raw milk measured by Total Bacterial Count (TBC). Bulk raw milk for bacteriological study was carried out in Regional Veterinary Laboratory (RVL), Biratnagar. Altogether, 520 milk samples for TBC were examined at farm and plant levels. Results showed a great variability of TBC for the overall study period. The lowest TBC (2.78 x 106) and the highest TBC (13.299 x 106) at two milk collection units revealed nearly fivefold difference. The results of mean TBC at farm (9.03 x 105) was nine fold of international standard (1 x 105), and mean TBC at plant (104.71 x 105) reached 104 folds the international standard. The TBC at farm level were non significant (P>0.05) for overall experimental period where as most of TBC at plant level differed (p<0.01) significantly. TBC at farm level differed significantly (P<0.01) from each record of same date at plant level. The highest number of TBC (16.5 x 106) was observed in the month of September, which was significantly (P <0.01) different from the rest of the months. The results obtained from the study indicated that the current situation is critical and needs real improvement from production point to processing plant.Key words: Raw milk; Total Bacterial Count (TBC)The Journal of AGRICULTURE AND ENVIRONMENTVol. 11, 2010Page: 46-50Uploaded Date: 15 Septembre, 2010
