Survival of Lactobacillus acidophilus and Bifidobacteria bifidum in Ice Cream for Use as a Probiotic Food

Hekmat, Sharareh 01 May 1991 (has links)
Ice cream mix (12% fat, 11% milk solids nonfat, 12.5% sugar, and 4.5% corn syrup solids) was fermented with Lactobacillus acidophilus and Bifidobacterium bifidum. Half of the mix was heat treated at 82°C for 30 minutes and cooled to 40-41°C. The other half was warmed to 40-41°C and inoculated with the starter cultures. Both were made into ice cream and stored at -29°C. Survival of L. acidophilus and B. bifidum and of β-galactosidase activity were monitored during 17 weeks of frozen storage. Reinforced clostridial medium was used to enumerate culture bacteria. Colony counts, after fermentation, for both L. acidophilus and B. bifidum were about 5 x 108. The population of cultures decreased less than one log cycle after initial freezing. After 17 weeks storage the bacterial counts were 1 x 107 for B. bifidum and were 4 x 106 for L. acidophilus. During the same period, β-galactosidase activity decreased only 31%. Therefore, frozen fermented dairy products provide a good vehicle to supply β-galactosidase enzymes to people who are lactose maldigestors. Frozen fermented ice cream was prepared at four different pH's (5.0, 5.5, 6.0, 6.5) by blending fermented mix with unfermented mix and then was frozen to produce samples for sensory evaluation. All samples were strawberry flavored. These were then evaluated by 88 judges. The preferred pH, based on overall acceptance, was 5.5. A second sensory evaluation was conducted to compare heat-treated with non-heat-treated ice cream. There were no significant differences in appearance, texture, flavor, and overall acceptance between the two samples. Our study shows that ice cream is a suitable vehicle for delivering these beneficial microorganisms and enzymes to consumers.

Study of Air Cell Migration and the Effect of Whipping Temperature on the Overrun, Body and Storage Stability of a Dairy-Based Frozen Whipped Topping

Locker, William J. 01 May 1972 (has links)
A dairy-based whipped topping consisting of 22.0 percent milk fat, 7.5 percent milk solids-not-fat, 12.0 percent sucrose, 10.0 percent corn syrup solids, 0.60 percent gum arabic, 0.06 percent carrageenin, 0.19 percent polyoxyethylene sorbitan rnonostearate, 0.19 percent polyoxythylene sorbitan tristearate, and 0.12 percent sodium stearoyl-2-lactylate was developed that would withstand the rigors of frozen storage. The best products were obtained when the topping was whipped on a Creamery Package 3M-30 continuous type ice cream freezer. Toppings whipped in the laboratory at temperatures higher or lower than -2.2 to -1.0 centigrade were weak and slightly wet. After 18 days frozen storage the toppings whipped at -2.2 centigrade had the best body and texture characteristics. Refrigerated storage after 18 days frozen storage resulted in an enlargement of the air cells and after about 10 days a stale flavor was detected. Commercial application of the formulation was considered feasible.

Determination of Hydroquinone in Cosmetic Creams by High Performance Liquid Chromatography.

Liu, Fuyou 14 August 2007 (has links) (PDF)
Hydroquinone is a most commonly used whitening agent in cosmetics. A high performance liquid chromatography method was developed and validated for the quantitative determination of hydroquinone in creams. Validation parameters such as linearity, precision, accuracy, and limit of detection and limit of quantitation were determined. HPLC was carried by reverses phase technique on a RP-C18 column with a mobile phase of water and methanol (pH 5.0) 70:30. The linearity in the range of 2.0-40.0 μg/mL presents a correlation coefficient of 0.9998. The LOD and LOQ were 0.16 and 0.53 μg/mL, respectively. The precision of the method was found to be satisfactory with a coefficient of variation below 2.2%. The recovery values were in the range of 92.4 to 99.0%. The method is sensitive, fast, and simple. It has been successfully applied to the determination of hydroquinone in cosmetic creams. The results obtained agreed well with the percentages given by the manufacturers.

Evaluation of Viability of Lactobacillus acidophilus La-5 During Simulated Digestion Process Using a Dynamic In Vitro Model

Tharani, Jenifer 01 May 2012 (has links) (PDF)
In recent years, there has been an upsurge in medical research assessing the therapeutic benefits of probiotic bacteria and growing commercial interest in food fortification with these bacteria. Probiotic bacteria such as L. acidophilus are known to be predominant Lactobacilli species in the intestinal tract of healthy humans and suggested to provide clinical health benefits such as enhancement of immunity against intestinal infections, prevention of diarrhea and hypercholesterolaemia and improvement in lactose utilization. Many studies have demonstrated the possibility of incorporating probiotic bacteria in an ice cream matrix and shown its viability can be maintained throughout the shelf life of the ice cream. However, there is limited information about the protective effect of ice cream on viability of incorporated probiotic bacteria during simulated gastric digestion using an in vitro dynamic model stomach. In phase one of this study, a preliminary study was conducted to determine the effect of air addition on the viability of L. acidophilus La-5. This was done by manufacturing low fat (4%) non-fermented ice cream mix supplemented with L. acidophilus La-5 to yield an initial population of 107cfu/g. The mix was processed with 60% and 100% overrun (OR) and stored at -10ᵒC for 90 days. The effect of air addition at different levels was tested post freezing and every 30 days throughout its shelf life of 90 days. The results showed less than one log reduction in the viable counts of L. acidophilus La-5 for both samples incorporated with 60% and 100% OR after freezing and the number of viable cells did not differ significantly (p>0.05) from day 1 to day 90. In phase two of this study, a 22 full factorial experimental design was used to evaluate whether the viscous nature of ice cream mix plays an important role in improving the survivability of L. acidophilus La-5 during simulated digestion against low pH and presence of mechanical shear and to determine whether initial inoculation level has any effect on the viability of L. acidophilus La-5 at the end of 2 hr simulated digestion. Non-fermented low fat (5%) ice cream mixes with high and low viscosity were produced by changing the amount of stabilizer/emulsifier blend and each of the two mixes were supplemented with two levels of L. acidophilus La-5 to obtain an initial population of 108cfu/g and 106cfu/g before freezing. These mixes were frozen with 60% overrun. The ice cream samples were digested for 2 hr in an in vitro model stomach called Human Gastric Simulator (HGS). This model included factors such as gastric secretions, mechanical shearing due to peristaltic contractions and temperature and pH control. No significant effect (p>0.05) of different levels of viscosity on the survivability of L. acidophilus La-5 was found during and at the end of 2 hr simulated in vitro digestion, irrespective of the difference in initial inoculation level. The initial supplementation level of L. acidophilus La-5 had a significant impact (p<0.05) on its survivability during the simulated digestion of ice cream samples, irrespective of the difference in viscosity. The log survival of L. acidophilus La-5 was on an average 3.64 log cfu/g and 4.08 log cfu/g for ice cream samples supplemented with higher and lower amount of L. acidophilus La-5, respectively at the end of 2 hr. Nevertheless, this difference in overall survival was not statistically significant (p>0.05). These studies demonstrated the efficacy of low fat non-fermented ice cream in maintaining high viable numbers of L. acidophilus La-5 throughout its tested shelf life of 90 days. In addition, protective effect of ice cream on the viability of L. acidophilus La-5 against harsh stomach conditions was observed, but this effect was not as a result of viscosity of ice cream. It was also found that an ice cream supplemented with 106cfu/g would result in a similar overall log reduction of L. acidophilus La-5 at the end of 2 hr simulated digestion compared to an ice cream supplemented with 108cfu/g. The aggressive stomach conditions had a negative impact on the survivability of L. acidophilus La-5 during digestion of all the ice cream samples, but this detrimental effect can be reduced by incorporating L. acidophilus La-5 into an ice cream matrix which would increase the opportunity of bacteria to reach the small intestine and provide the desired health benefit.

Sensory and chemical/nutritional characteristics of concept foods made from underutilized sweet potato roots and greens

Kim, Shinyoung 09 August 2019 (has links)
Frozen desserts and a smoothie were developed from underutilized sweet potato roots and from greens, respectively. Frozen desserts were formulated with mashed sweet potato, coconut oil, and dairy, almond, or soy milk. Sweet potato greens were blanched and frozen before being made into a smoothie. Increased mash in the frozen desserts resulted in better (p≤0.05) color, overall intensity of flavor, and sweet potato flavor. Descriptive and consumer panelists found no differences (p>0.05) in frozen desserts with difference base milk products. Almond milk frozen dessert was lower in total solids, protein and Brix (p≤0.05), compared to dairy and soy milk. Greens blanched for 30s showed complete peroxidase inhibition and acceptable texture. Blanching decreased carbohydrates and soluble minerals of greens mainly due to water. The results showed that consumers liked lactoseree sweet potato-based frozen desserts and showed that properly blanched greens could be used in valueded products like smoothies.
