The study was designed to evaluate the physico-chemical, microbial and sensorial quality of beef incorporated with different levels of vinegar at refrigerated storage (4±1ºC). Fresh beef samples were divided into three different batches i.e. T0 = control (without vinegar), T1 = 5% vinegar and T2 = 10% vinegar. The samples were evaluated for sensory properties (color and flavor), physico-chemical properties (pH, cooking loss, FFA, POV and TBARS) and microbial counts (TVC, TCC and TYMC) on 0, 7 and 14 days of storage at 4ºC. The obtained results showed that addition of different levels of vinegar significantly (p<0.05) influenced on sensory, physico-chemical and microbiological properties compared to control samples. Comparatively better color and flavor were found in T1 and T2 respectively among the treatments (p<0.05). Lower pH was observed in T1 and T2 compared to control treatment. POV, FFA and TBARS values were found better in T1, whereas the other treatments fluctuated slightly. The lowest microbial counts were significantly lower in higher vinegar treated groups along with at different day’s intervals in TVC, TCC and TYMC (p<0.01). It might be stated from the experiment that vinegar is a means of fresh beef preservation for a short time. From this study, it also concluded that 10% vinegar is effective for short term preservation of beef satisfactorily at refrigerated condition.

The physico-chemical properties (proximate, salt content, water activity (aw), pH) and lipid oxidation of droëwors (dried salted/spiced meat sausages) produced with zebra meat and different sheep fat levels (10, 15, and 20% by weight) measured at day 0 (before drying), day 2 (after drying at 30 °C and 40% relative humidity), and over a 90 day storage (day 17, 32, 47, 62, 77, and 92) under vacuum at 25 °C were investigated. The use of lower fat levels (10 and 15%) in the formulation resulted in higher weight loss during drying and droëwors with higher protein, ash, and salt content and lower aw and pH compared to the droëwors made with 20% fat. The pH increased (p < 0.001) during storage for all the fat levels, while the moisture content and the aw were stable as expected. TBARS values were the highest in droëwors made with 20% of fat after drying (day 2), but droëwors made with 10% of fat reached similar maximal values on day 17. Formulations containing 15% sheep fat displayed the lowest TBARS values after drying and along storage, and thus had the best characteristics in relation to oxidative stability.

In the present study, Rhododendron flowers were used for the preparation of biscuits to enhance the utility of this valuable flower. Dried Rhododendron petals powder was incorporated at different levels (0%, 5%, 10% and 15%) in biscuits and their sensory and physico- chemical properties were evaluated. The results revealed that, the length and thickness of biscuits decreased by increasing the proportion of Rhododendron powder in biscuits. Addition of Rhododendron powder to wheat flour significantly increased the content of moisture, ash (0.75 to 1.20 %), protein (3.06 to 4.96 %), fibre (0.07 to 0.67 %) and iron (3.90 to 4.19 mg/100g). The sensory results showed a significant decrease (7.70 to 7.10) in the overall acceptability by the addition of Rhododendron power to wheat flour but the product remained acceptable in terms of sensory acceptability up to the level 10 per cent. From the study it can be concluded that a maximum of 15% Rhododendron powder can be incorporated to prepare acceptable quality of biscuits.

Four different types of rasomalai were prepared from cow milk chhana (acid curd) with the addition of different levels of soy chhana. The prepared rasomalai were named as ‘A’ (100% cow milk chhana), ‘B’ (75% cow milk chhana+25% Soy Chhana), ‘C’ (50% cow milk chhana+50% soy chhana) and ‘D’ (25% cow milk chhana+75% soy chhana). The qualities of prepared rasomalai were evaluated by using physical and chemical parameters. It was observed that the addition of soy chhana with cow milk chhana decreased the organoleptic score of the prepared rasomalai. The moisture, total solids and carbohydrate content of the sample were not significantly differed, but protein (p<0.05), ash (p<0.05), fat (p<0.01) content and acidity percent (p<0.01) of the samples were significantly decreased in addition of soy chhana with cow milk chhana. Considering the physico-chemical properties of all samples, it was found that most suitable and acceptable quality of rasomalai can be prepared by admixture of 25% soy chhana and 75% cow milk chhana.DOI: http://dx.doi.org/10.3329/bjas.v44i1.23144            Bang.

Efforts to develop the production technology of high quality red palm-oil (RPO) in order to provide source of food ingredient that naturally rich of nutrients, become urgents regarding the need of such products drastically increased recently. Application of deodorization technology by temperature, time, and deodorizer pressure combinations (engineering of deodorization process) are studied and evaluated to obtain good quality of RPO. Crude palm oil (CPO) used in this research were supplied by PT. Salim Ivomas (Bimoli) Jakarta. The equipments used were degumming and neutralization unit, deodorization unit and other equipment units to analize the oil physico-chemical properties. The research consisted of 5 stages as the following: characterising CPO physico-chemical properties, conducting chemically degumming and deacidification, process enginering of deodorization, characterizing of physico-chemical properties and organoleptic of RPO resulted, and analyzing data for product resulted from process engineering applied. Deodorization with the range of temperature and process duration of 135–145 oC (408–418 K) and 1–4 hours have led to carotene retention decreasing (%) following the equation “Carotene Retention (%) = -764 x ln(absolute temperature) + 4693” and process duration with the equation “Carotene Retention (%) = -7.81 x ln(process duration) + 91.02”; and also resulted odor intensity with the equation “Odor Intensity = 0.08 x (squared absolute temperature) – 66.88 x (absolute temperature) + 13823” and duration process with the equation “Odor Intensity = 0.315 x (squared process duration) – 1.52 x (process duration) + 5.268”. Effective deodorization to produce RPO with the content of free fatty acid and peroxide value that met the requirements of Indonesian National Standard (SNI) quality of carotene content above 400 ppm and odor scale below 3.3, were the combination of temperature (T) of 141.34 oC, heat process duration (t) of 2.35 hours and vacuum pressure of (P) of 20 mmHg. The resulted RPO contained free fatty acid and peroxide value of 0.11% dan 0.12 meq/kg oil respectively, total carotene of 444.09 ppm and odor value of 3.21
