Twelve fermented yellow mombin ice creams were produced with different starter cultures (Lactobacillus acidophilus 74-2, L. acidophilus LAC 4 and yoghurt starter culture), final pH (4.5 and 5) and concentrations of added cream (5 and 10%). Probiotic culture stability, melting properties and sensory acceptance were evaluated in ice cream samples. The mixes were frozen and stored for 105 days at -18°C. The melting rates were lower for samples with a pH of 4.5. Both probiotic cultures resisted the freezing process and, although a tendency for the counts to decrease during storage was detected, they were still higher than 10 6 cfu/g after 105 days, even in products with a pH of 4.5. A pH 4.5, 5% cream and L. acidophilus LAC 4 ice cream received significantly higher sensory scores when compared with pH 5, 10% cream and L. acidophilus 74-2 ice cream. The fermented yellow mombin ice cream was a suitable food for the delivery of L. acidophilus strains, with excellent viability and acceptable sensory characteristics.

The study was conducted to prepare control, probiotic (Lactobacillus acidophilus), and synbiotic (L. acidophilus and inulin) ice cream, L. acidophilus content, pH, titratable acidity, sensory properties were evaluated during frozen storage periods. L. acidophilus counts were the higher in synbiotic ice cream, adding inulin to probiotic ice cream enhanced significantly (P<0.05) the content of L. acidophilus. Freezing process caused a decrease in L. acidophilus counts along with storage periods in all the samples of ice cream. Synbiotic ice cream was the lower in pH values and the higher in TA values compared to the other ice cream samples. Synbiotic ice cream was the better in overall acceptance followed by probiotic and control ice cream, respectively. So, ice cream fortification with L. acidophilus probiotic bacteria and prebiotic inulin have a positive influence on all sensory characteristics. Probiotic content of both synbiotic and probiotic ice cream could be considered as functional therapeutic healthy product since it was more than the lowest concentration of probiotic bacteria to provide the beneficial attributes which are 106 cfu/g at the consumption time of the product.

Abstract In this study, cow (W)’s milk was replaced by soy (S), coconut (C) and various combinations of coconut or cow milks with soy milk in order to produce fermented probiotic ice cream. The changes in ice cream eating qualities and physical properties were evaluated. Fermented ice cream containing vegetable milks showed a slower melting rate and higher apparent viscosity and particle size and also lower total acceptability than fermented cow milk ice cream (control). Ice creams containing Lactobacillus acidophilus (La-05; L) showed a lower melting rate and higher apparent viscosity and particle size than ice creams containing Bifidobacterium bifidum (Bb-12; B). Regardless of the starter culture used, all of sensory analysis scores decreased in ice creams with higher soy milk amount. The vegetable milks may offer ice cream manufacturers an alternative source of cow milk as a functional ice cream.

Four types of ice creams were manufactured using stevia (S), milk powder (PP), emulsifier (PS) and UHT whole milk (C), and were investigated for physical, chemical and sensory characteristics. The pH values of ice cream samples ranged from 5.82 to 6.62. The hardness values from textural analyses was around 3.40 and 598.61 N. The highest overrun ratio (29.27 %) was found in PP ice cream during the first week of storage. The substitution of sucrose by stevia powder led to a significant elevation of the hardness of ice cream.

In this study, the possibility of replacing stabilizers with microbial transglutaminase (MTG) enzyme in fat-reduced ice cream production was studied. In addition, the stage of adding (before or after the heat treatment) the MTG enzyme to ice cream was also investigated. Five different ice creams (A and C containing 1 unit MTG/g protein without stabilizer, B and D containing 0.5 unit MTG/g protein and 0.35 % stabilizer, which also consist of the mixture of Carrageenan (E 407), Guar gum (E 412), Xanthan gum (E 415) and Sodium alginate (E 401), and E (control) containing 0.7 % stabilizer) were manufactured. MTG has been added to samples A and B after heat treatment while it was added to C and D samples before the heat treatment. An experimental analysis related to the overrun, viscosity melting properties, pH, titratable acidity, dry matter, fat, protein, sensorial and microstructural properties of ice creams was carried out. According to the results, the amount and the adding stage of MTG significantly affected overrun, melting, viscosity, coldness, firmness, smoothness, mouth coating, color, appearance, taste, smell scores, and also microstructure of ice creams (p&lt;0.01). Results also showed that MTG could be used together with other stabilizers after heat treatment in the production of ice cream. Moreover, our findings demonstrated that sample B was the closest to control in terms of sensorial properties.

The possibility of obtaining kombucha from winter savory tea has been tested in the laboratory bioreactor by applying starter cultures and traditional way of inoculation. On the basis of the obtained results, it can be concluded that applying the inoculating method with the beverage from the previous process of biotransformation yielded kombucha beverage (capacity 15 I) from winter savory tea in the laboratory bioreactor. The application of defined starter culture from the isolate of yeast and acetic acid bacteria of local tea in the glass jar (capacity 5 I) gave 3 litres of kombucha beverage, which is acceptable according to the basic parameters and sensory characteristics. However, the application of the same starter culture in the laboratory bioreactor did not result in synchronized activity of yeast and bacteria.

Recent trend in production of healthy food products has stimulated ice cream manufacturers to minimize the saturated fat content by replacing it with high-unsaturated fat or oil such as canola oil, yet maintaining the physical properties of the end product. Addition of maltodextrin (MD) into the formulation may assist in obtaining the desirable physical properties. Therefore, the objective of this study was to develop hard ice creams containing different ratios of canola oil and MD. Four ice cream formulations were prepared by weight: MD-0 (5% oil, 0% MD), MD-1 (4% oil, 1% MD), MD-2 (3% oil, 2% MD), and MD-3 (2% oil, 3% MD). Both MD-2 and MD-1 exhibited the highest (45.05±4.28%) and the lowest (32.49±1.20%) overrun, respectively, yet there was no significant difference (p > 0.05) between all ice creams in terms of hardness (3.20-4.79 kg). Additionally, there was no significant difference (p > 0.05) between MD-0, MD-1, and MD-2 in their melting rates which were significantly slower (p < 0.05) than those of MD-3. In overall, decreasing the amount of oil (i.e. increasing amount of MD) resulted in significant (p < 0.05) increase in overrun, yet had no significant (p > 0.05) effect on the ice cream's hardness and melting rate except for MD-3 for the latter. The ice cream that exhibited the most desirable physical properties was MD-2 (overrun, 45.05±4.28%; hardness, 3.73±0.75 kg; slowest melting rate). This finding highlighted the potential of MD in providing desirable texture to the ice creams to certain extent. Future studies are recommended in maintaining the ice cream's flavour and physical properties upon storage, and in determining its sensory acceptability among consumers.

The objective of this study was to evaluate the effects of supplementation of dairy cows with different fatty acid sources (soybean oil (SO) and fish oil (FO)) on milk production, milk composition, milk fatty acid profile, and physicochemical and sensory characteristics of ice cream. During 63 days, fifteen Holstein cows averaging 198 ± 35 days in milk were assigned to three groups: control diet with no added lipid (n = 5 cows); and supplemented diets with SO (n = 5 cows; unrefined SO; 30 g/kg DM) or FO (n = 5 cows; FO from unrefined salmon oil; 30 g/kg DM). Milk production, milk fat, and milk protein were not affected by treatments. Saturated fatty acids in milk fat were decreased with SO and FO compared with control. C18:2 cis-9, cis-12 was increased with SO whereas C18:2 cis-9, trans-11, C20:3n-3, C20:3n-6, C20:5n-3, and C22:6n-3 were the highest with FO. Draw temperature and firmness were higher in SO compared to control and FO ice creams. Melting resistance was higher in FO compared with control and SO ice creams. Supplementation of cow diets with SO and FO did not have detrimental effects on milk production, or ice cream physicochemical and sensory characteristics.

Fermentation was used since ancient times as an easy method of food preservation, which also maintains and/or improves the nutritional and sensory properties of food. A research as aimed at identifying strain of lactic acid bacteria (LAB) from fermented caridean-shrimp, which properties suitable for starter cultures in food fermentation. A total of 18 LAB stains were obtained from ten different samples, in each sample consisted of commercial LAB strain that isolated from ten samples of caridean-shrimp. The LAB strains from ten samples were screened for resistance to biological barriers (acid and bile salts), and the three most promising strains were selected. The three bacteria strains were isolated from samples of caridean[1]shrimp and were characterized by the API 50 CHL system of identification. Three lactic acid bacteria species were identified and included Lactobacillus plantarum, and Lactobacillus acidophilus. Strain Y’11b,2, Y’11e,2, Y’85,1, which showed probiotic characteristics reducing cell growth of cancer, could be suitable as a starter culture for food fermentation because of its strong acid production and high acid tolerance. This is the first report to describe bacteria, isolated from caridean[1]shrimp, Lactobacillus Plantarum (Y’11b,2, Y’11e,2) and Lactobacillus acidophilus (Y’85,1) which have the probiotic characteristics and the acid tolerance needed for its use as a starter culture in food fermentation.

Red Palm Olein

Red palm olein (RPOL) is rich in nutritional and antioxidant compounds including carotenoids, tocopherols, and tocotrienols which makes it beneficial in food applications. However, to maintain the colloidal stability of RPOL in ice cream is challenging. Therefore, this study was carried out to formulate value-added ice creams supplemented with RPOL (0.1-5.0% w/w) in combination with guar gum (GG; 0.0-0.4% w/w) or xanthan gum (XG; 0.0-0.4% w/w) as stabilizers. Physical properties and sensory acceptance of these ice creams were determined in comparison with selected commercial ice cream samples (CM-ice creams). Ice cream with 0.1% RPOL and 0.4% guar gum resembled CM-ice creams in terms of viscosity (9.08±0.05 Pa.s.), hardness (3.59±3.12 kg), and amount of melted ice cream/30 min (62.00±2.83%). Meanwhile, ice cream with 0.1% RPOL and 0.4% xanthan gum was similar with CM-ice creams in their viscosity (9.19±0.04 Pa.s.) and hardness (0.60±0.25 kg), yet was relatively lower in the amount of melted ice cream/30 min (33.46±5.06%). All ice creams appeared red and yellow due to the presence of RPOL, and the colour intensity was enhanced with the presence of the stabilizers. The RPOL-based ice creams displayed lower score in sensory properties than those of CM-ice creams, thus highlighted the necessary attributes that need to be improved in future studies.

The Impact

The local cheese factories currently use bovine commercial starter cultures, and the spreadable cheese process is not standardized. A detailed understanding of the effect of pasteurization temperature, starter culture, and incubation temperature must allow producers to optimize the process, increase cheese yield, and improve the quality of the final product. The main objective of the study was to describe the preparation method of spreadable goat cheese and investigate the effects of specific processing conditions (pasteurization temperature, starter culture, and incubation temperature) on the composition, yield, rheology, and sensory characteristics of the final product. Results showed the impact of pasteurization temperature, starter culture, and incubation temperature on spreadable goat cheese. The results indicated that it is possible to improve cheese yield, rheological properties, and sensory analysis when milk is pasteurized at 75°C for 30 minutes; cheese yield can also be improved by lowering incubation temperature to 37°C. Cheeses made with autochthonous starter culture showed better sensory characteristics and higher pH compared to the cheeses made with commercial culture.
