The most important issues that affect consumer fruit acceptance in the ‘Hass’ avocado international market are flesh disorders. These defects can be influenced by both pre- and postharvest factors. The aim of this work was to evaluate the effect of the harvest season, storage time, mineral content, and preharvest variables on internal fruit disorders. Here, fruit was sampled from four farms in Antioquia (Colombia) at 22%, 26%, and 30% dry matter (DM) content. Samples were stored and ripened under simulated export conditions. Then, flesh bruising, flesh discoloration, body rots, vascular browning, stem end rot, and mineral content were assessed. The results showed that flesh disorders differ among farms and by harvest index and storage time. The most frequent defects found were vascular browning and stem end rot. Boron, calcium, nitrogen, manganese, magnesium, and potassium have a strong relationship with flesh disorders. Therefore, high boron and calcium contents, as well as a harvest at 26% DM, can substantially reduce avocado flesh disorders and improve internal fruit quality. Farmers that had a high flesh and soil mineral content and low rainfall and temperature produced fruits with fewer internal disorders.

The effects of fat and non fat dry matter (NFDM) concentration and storage time on the physical properties and acidity of yoghurts made using commercial probiotic cultures (ABY and ABT-1) were investigated by using response surface methodology. All yoghurts made with ABY and ABT-1 cultures exhibited shear thinning behaviour. The power low model was used to describe the shear thinning behaviour of yoghurt samples. The flow behaviour index ( n) and the consistency coefficient ( m) were determined. NFDM levels in milk strongly affected syneresis, apparent viscosity at a constant speed of 100rpm, flow behaviour index and the consistency coefficient. Titratable acidity and pH were mainly affected by the storage time. Under all conditions examined, yoghurt made with ABT-1 culture had higher apparent viscosity, consistency coefficient and pH value than those of the yoghurt made using ABY culture.

An experiment was conducted to find out the effect of oat meal as a source of dietary fiber to formulate enriched broiler nugget. For this purpose, nuggets were prepared into four different groups such as treatment 1: 10% wheat flour nugget, treatment 2: 20% wheat flour nugget, treatment 3:10% oat meal nugget and treatment 4: 20% Oat meal nugget. All parameters were analyzed at 0, 15th and 30th days of storage period. The proximate composition of different nuggets batter was analyzed and highly significant differences were found in dry matter (%) and pH. Dry matter was lower, while pH was higher in control nugget (Treatment 1). Significant differences were found in crude protein (%), ether extract (%) among different nuggets, as well as among different storage time. Significantly higher DM (%), Ash (%) and EE (%) was found in broiler meat with 20% oat meal, while higher crude protein (%) were found in broiler meat+10% wheat flour. Crude protein (%) and DM (%) increased, while Ash (%) and EE (%) decreased with increase of storage time.  The storage period had significant effect on different biochemical (FFA, POV and TBARS value) and microbial (TVC, TCC and TYMC) tests. In all cases, the values were increased with increase of storage time. The surface color (CIE L*, a*, b*) of nuggets of different treatments at different storage period were measured.  No significant differences in b* value were found among broiler meat nuggets and storage time. On the other hand, different types of nuggets and storage period had a significant effect on L* and a* value. Significantly higher a* value was found in broiler meat with 10% wheat flour (T1). In sensory analysis, no significant differences were found in flavor, off-flavor, juiciness, tenderness and overall acceptability among four types of sausages. It could be concluded that addition of oat meal as a source of dietary fiber did not differ the overall acceptability of broiler meat nuggets compare to broiler meat nuggets with wheat flour. Bang.

The experiment was conducted to find out the effect of salt and storage temperature on the quality of sausage. For this purpose sausage samples were divided into two portions. One is called fresh sausage and another is preserved sausage at different temperature. Then the fresh samples as well as the preserved samples were divided into four subdivisions, treated with different salt levels and e.g. control group-0% and the others are 1.5%, 3% and 5% of salt concentration. The preserved samples were stored at 4°C and -20°C. Samples preserved at 4°C were stored in the refrigerator for 21 days and were analyzed on 7th, 14th and 21th day and on the other hand samples preserved at -20°C were stored in the freezer for 60 days and were analyzed on 15th, 30th, 45th and 60th day. Dry matter and Ash content of all the samples increased with the advancement of storage time and salt concentration level. Dry matter in fresh sample was less compared to preserved samples. Crude protein (CP) percent of fresh samples were 23.13, 22.63, 22.48 and 22.44 at different salt concentration level. The values of CP, DM, Ash & Fat also varied among the samples significantly (P<0.01). Sausage can be preserved for 60 days in different techniques with different changes in the quality. Highly significant difference was observed in preserved samples than in fresh samples at different salt levels. Fresh sausage treated with 1.5% salt found to be more acceptable in terms of sensory evaluation.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16561Progress. Agric. 23(1 & 2): 15 – 24, 2012

The experiment was conducted to find out the effect of salt and storage temperature on the physico-chemical properties of meatball. For this purpose meatball samples were divided into two parts; one is called fresh meatball and another is preserved meatball at different temperatures. Then the fresh samples as well as the preserved samples were divided into four subdivisions. Then these are treated with different salt levels (0, 1.5, 3 and 5% salt level).These Samples were stored at 4oC and -20oC temperature. Samples preserved at 4oC were stored in the refrigerator for 21 days and were analyzed on 7th day, 14th day and 21st day and samples preserved at -20oCwere stored in the refrigerator for 60 days and were analyzed on 15th day, 30th day, 45th day and 60thday. Dry matter content of all the samples increased with the advancement of storage time, temperature and salt concentration. Ash value decreased with the increase of storage time. Fat value of all the samples decreased with the advancement of salt concentration, storage time and temperature. pH value of all the samples decreased with the increasing of salt concentration, storage time and temperature. Cooking loss of all the samples increased with increasing of salt concentration but decreased with increasing of storage time and temperature. Dry matter in fresh sample were less than in preserved samples. CP % of fresh beef meatball was 22.31, 20.55, 14.55 and 20.13 at different salt concentration. The values of CP, DM, Ash and Fat also varied among the samples significantly (P<0.01). Beef meatball can be refrigerated for 60 days in different techniques with more or less difference in the quality. Highly significant differences are observed in preserved samples than in fresh samples at different salt levels. Fresh beef meatball treated with 1.5% salt found to be more acceptable in terms of sensory evaluation.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19117 Progress. Agric. 24(1&2): 137 - 147, 2013

Effects of method of drying beef and buffalo meat and storage time on quality were investigated. Six treatments were applied: drying beef with salt (B1), drying beef without salt (B2), drying beef with salt and spices (B3), drying buffalo meat with salt (B4), without salt (B5) and with salt and spices (B6). Taste and smell of all samples were acceptable up to 120 days of storage. The dry matter (DM), protein, ether extract (EE) and ash content decreased with storage time. The initial DM, crude protein (CP), EE and ash content of the samples were 92.1-95.2%, 77.0-78.6%, 5.0-6.5%, 8.0-12.8%, respectively. After 120 days of storage DM, CP, EE and ash content of the samples ranged from 87.8-89.1%, 72.9-74.0%, 5.0-5.9%, 7.4-9.7%, respectively. CP and EE percentage in beef was higher than buffalo meat, but beef contained less DM and ash. At the end of storage beef dried with salt contained highest protein (74.0%) and buffalo meat dried without salt contained lowest protein (73.0%). There was a significant (p<0.05 to 0.01) effect of drying method, salt and spices in beef and buffalo meat. With the elapse of storage time quality of meat degraded significantly (p<0.05 to 0.01). The degradation was lower in beef dried with salt than in beef dried without salt beef or beef dried with salt and spices, and buffalo meat. It is suggested that salt drying may be a useful method of meat preservation. DOI: 10.3329/bvet.v26i1.4629 Bangl. vet. 2009. Vol. 26, No. 1, 31-38

Demand for fresh cheese increases along with welfare. As Indonesia has a muslim population around 200 millions therefore there is a demand for halal cheese starter. The purpose of this research was to prove that the use of lemom juice as a replacement rennet is able to coagulate milk while produce fresh cheese which is also a halal because it comes from plants.This study aims to determine the lemon juice (citrus limon) in the process of milk coagulation. This research method used a 4 x 4 Factorial Completely Randomized Design with 2 replications of factor A, levels of lemon juice, namely A0 = 0.01% rennet, A1 = 5% lemon juice, A2 = 10% lemon juice, A3 = 15% lemon juice, and factor B storage time B0 = 0 days, B1 = 5 days, B2 = 10 days and B3 = 15 days. The variables measured were chemical compositions including moisture content, dry matter content, fat content, protein content. Based on the research results, it was found that from the addition of four levels of lemon juice used and four variations of storage time, giving 10% lemon juice (A2) and storage time of 15 days (B3) was the optimal treatment to increase moisture content, dry matter content, fat content, protein content in cheese and can be used as an alternative of halal cheese starter.
