Avaliou-se a influência da betaciclodextrina (beta-CD) na qualidade sensorial, na composição química e propriedades físicoquímicas (proteína, lipídios, sólidos totais, cinzas, acidez em ácido láctico, carboidratos totais e pH) do iogurte de leite de cabra, sabor morango. Para a avaliação sensorial utilizouse o teste de categoria. Os resultados demonstraram que houve diferença significativa ao nível de 1% de probabilidade entre os tratamentos teste e controle, para o iogurte contendo 0,40% de beta-CD, mostrando a eficiência da beta-CD na minimização do "sabor caprino" nesta concentração. As análises físico-químicas não apresentaram diferença estatística entre os tratamentos. O iogurte de leite de cabra adicionado de beta-CD pode tornar-se mais uma alternativa para o beneficiamento de leite de cabra e mais uma opção para indivíduos alérgicos às proteínas do leite de vaca. Abstract The influence of betaciclodextrin (betacd ) was evaluated in sensorial quality, chemical composition and physical chemical properties (protein, lipids, total solids, ashes, acidity in lactic acid, total carbohydrates and pH) of goat milk yogurt, strawberry flavor. For sensorial evaluation the category scale test was utilized. The results demonstrated significant differences at level of 1% probability between the test and control treatments, for the yogurt containing 0,40% of betaCD, showing the efficiency of betaCD in the minimization of the goaty flavor in this concentration. The physical chemical analysis didn’t show significant statistical difference between the treatments. The goat milk yogurt with addition of betaCD can become another alternative for goat milk processing and other option for allergic individuals to cow milk protein.

A new type of cow’s milk, called A2 milk, has appeared in the dairy aisles of supermarkets in recent years. Cows’ milk generally contains two major types of beta-casein as A1 and A2 types, although there are 13 genetic variants of β-casein: A1, A2, A3, A4, B, C, D, E, F, H1, H2, I and G. Studies have shown that A1 β-casein may be harmful, and A2 β-casein is a safer choice for human health especially in infant nutrition and health. The A2 cow milk is reportedly easier to digest and better absorb than A1 or other types of milk. The structure of A2 cow’s milk protein is more comparable to human breast milk, as well as milk from goats, sheep and buffalo. Digestion of A1 type milk produces a peptide called β-casomorphin-7 (BCM-7), which is implicated with adverse gastrointestinal effects on milk consumption. In addition, bovine milk contains predominantly αs1-casein and low levels or even absent in αs2-casein, whereby caprine milk has been recommended as an ideal substitute for patients suffering from allergies against cow milk protein or other food sources. Since goat milk contains relatively low levels of αs1-casein or negligible its content, and αs2-casein levels are high in the milk of most dairy goat breeds, it is logical to assume that children with a high milk sensitivity to αs1-casein should tolerate goat milk well. Cow milk protein allergy (CMPA) is considered a common milk digestive and metabolic disorder or allergic disease with various levels of prevalence from 2.5% in children during the first 3 years of life to 12–30% in infants less than 3 months old, and it can go up to even as high as 20% in some countries. CMPA is an IgE-mediated allergy where the body starts to produce IgE antibodies against certain protein (allergens) such as A1 milk and αs1-casein in bovine milk. Studies have shown that ingestion of β-casein A1 milk can cause ischemic heart disease, type-1 diabetes, arteriosclerosis, sudden infant death syndrome, autism, schizophrenia, etc. The knowledge of bovine A2 milk and caprine αs2-casein has been utilized to rescue CMPA patients and other potential disease problems. This knowledge has been genetically applied to milk production in cows or goats or even whole herds of the two species. This practice has happened in California and Ohio, as well as in New Zealand, where this A2 cow milk has been now advanced commercially. In the USA, there have been even promotions of bulls, whose daughters have been tested homozygous for the A2 β-casein protein.

Milk Adulteration

Adulteration of goat milk is usually done using cow’s milk product. Cow milk is used as it is widely available and its price is cheaper compared to goat milk. This paper shows a development of candidate tools for milk adulteration using cow milk. A quartz crystal microbalance immunosensor was developed using commercial crystal resonator and polyclonal antibody specific to cow milk protein. A specific protein at 208 KDa is found only in cow milk and does not exist in goat milk. The existence of this protein can be used as an indicator of cow milk content in a target solution. To detect the PSS 208 kDa protein, antibody specific to the PSS 208 was developed. The purified antibody was immobilized on top of the sensor surface on a polystyrene layer. The fraction of the immobilized antibody on the sensor was found at 1.5% of the given antibody. Using a static reaction cell, the developed immunosensor could detect the specific cow milk protein in buffer solution. The detection limit is 1 ppm. A linear relationship between frequency change and specific protein of cow milk concentration is found from a concentration of 1 ppm to 120 ppm.

We studied the effects of goat and cow milk fat on the digestive utilization of this nutrient and on some of the biochemical parameters that are related to the metabolism of lipids, using rats with a resection of 50% of the distal small intestine and control animals (transected). The fat content in all the diets was 10% but the lipid quality was varied: the standard diet was based on olive oil, while the other two diets included fat obtained from lyophilized goat milk and cow milk, respectively. The digestive utilization of the fat was lower in the resected animals than in the transected ones for all three diets studied. In both resected and transected animals, the apparent digestibility coefficient (ADC) of the fat was greater with the standard diet (olive oil) than with diets whose fat content was provided by goat or cow milk. The digestive utilization of the fat was greater in the transected and resected rats receiving a diet of goat's milk (rich in medium-chain triglycerides) than those given a cow-milk-based diet, and more closely approached the values obtained for olive oil. The consumption of goat milk reduced levels of cholesterol while levels of triglycerides, HDL, GOT and GPT remained within the normal ranges, for both transected and resected animals. The advantageous effect of goat milk on the metabolism of lipids with respect to cow milk suggests that the former should be included in the diet in cases of malabsorption syndrome.

The aim of this work was to produce and evaluate the physiochemical properties of cow milk based beverage made from a blend of cow milk, honey, cocoa powder, ginger and garlic. The  composition of the samples were as follows: sample A (1 L cow milk), sample B (1 L cow milk, 0.12 L honey, 25 g cocoa powder), sample B served as base ingredients for samples C and D and prepared 1% ginger, 0.5% garlic were added to samples C and D, respectively. Sample A and sample E (vitamilk), respectively served as control I and control II. The chemical properties and proximate composition of the milk beverage samples were investigated. The result of chemical properties showed that the pH values ranged from 6.11 to 6.52 and were all slightly acidic while the percentage titratable acidity had the highest value of 0.168 for sample D and the least value of 0.086 for sample A. In terms of proximate composition, sample A had the highest percentage moisture content of 90.75±0.21 while sample C had the least moisture content of 87.7±0.28. The % protein, carbohydrate, fat, and ash contents increased as 1% ginger and 0.5% garlic were added to samples C and D and were significantly difference (P<0.05) for all the samples. Sample C had the highest value of 5.15% protein content while sample A had the least value of 2.85%. The percentage ash content ranged from 0.96±0.007 to 0.58±0.007. The fiber content of all the samples were below 2.25±0.007. A similar trend was also observed for the values of minerals and vitamins which showed a significant difference (P<0.05). This work has shown that there is improved nutritional content of the samples B, C and D which will go a long way to alleviate malnutrition. The pH of all the samples were near neutral, this could negatively affect the shelf stability of the milk beverage as a result of possible microbial infestation and thus there is every need to keep the product always refrigerated before use or should be consumed fresh.

Cow Milk Protein Allergy

Background. Till the present time the problem of food allergy remains to be the topical subject and demands further development of therapeutical and prevention programs, including diet therapy for nursing mothers. The work is aimed at clinical and immunological evaluating of diet therapy of mothers whose children have atopic dermatitis on the back of breast feeding only. Methods. There were 100 «mother and child» couples kept under observance, that were divided into two groups. All the children had atopic dermatitis (AD), associated to cow milk protein allergy. Nursing mothers from both the groups were treated by diet therapy according to which the cow milk in diet have been replaced either with goat milk of New Zealand origin (first group had 43 «mother and child» couples) or with nondairy products (second group had 57 «mother and child» couples). Effectiveness of diet therapy of nursing mothers has been evaluated by the dynamic of clinical and immunological symptoms of atopic dermatitis in 1-3 months from treatment beginning. Immunological effectiveness of the treatment has been evaluated by the dynamic of indexes of specific IgE and IgG antibodies to cow milk protein, β-lactoglobulin, casein, soy protein and goat milk protein and cytokines levels. Results. In the course of treatment, that included diet therapy of nursing mothers and antiallergic cure of infants, both the groups showed remission and saved breast feeding. Immunological evaluating of therapeutic intervention’s effectiveness revealed the improvement of total IgE, allergenspecific IgE and IgG antibodies to cow milk protein and its fractions, as well as to soy and goat milk protein in blood of all the children on the back of breast feeding. Moreover, complex therapy conduced decreasing of pro-inflammatory cytokines concentration in blood. Conclusion. These findings prove reasonability of dietary treatement for nursing mothers, whose children have atopic dermatitis, associated associated to cow milk protein allergy.

Background. Clinical and immunological estimation of efficiency of different special formulas in children with atopic dermatitis due to food allergy. Methods. Fifty four children with atopic dermatitis aged 0,5—3 years old were examined. Children were divided into three groups on the base of their diet therapy. The 1 st group included 15 patients on the hypoallergenic milk-free diet, the 2 nd group (18 patients) was fed by goat milk formula, and the 3 rd group (21 children) was fed by special formula with high hydrolyzed protein. The dynamics of serum levels of IgE and IgG antibodies to cow milk protein and its fractions, and dynamics of cytokine levels (IL-4, IL-5, and IL-10) were measured during different types of diet therapy. Results. The positive skin changes during diet therapy included decrease of erythema, exudation and itching, gradual regression of rash. In 3 months of therapy complete clinical remission was achieved in 10 (66,7%) children in the 1 st group, in 14 (77,8%) children in the 2 nd group and in 15 (71,7%) children in the 3 rd group. The significant decrease of levels of IgG antibodies levels to cow milk protein and its fractions in children during different elimination diets was determined. The significant decrease of levels of specific IgE antibodies to cow milk protein (p

Apoptosis Markers

Background. To estimate the dynamics of soluble apoptosis markers in infants with atopic dermatitis for updating mechanisms of immunopathogenesis and improvement of diet therapy. Methods. We observed 66 bottle-fed infants aged 1,5—12 months old (boys -47, girls — 19) with atopic dermatitis (AD). The sensibilization to cow milk protein was revealed in all 66 infants. Detected allergen-specific IgG and IgE antibodies to cow milk protein, its fraction and goat milk protein were the reason to include infants into the 1st group and feed with hydrolyzed formula (27 infants). 39 infants in the 2nd group, who were not sensibilized to goat milk protein, were fed by goat milk based formula. Serum levels of soluble apoptosis markers (sCD153, caspase-8, sFas-L, caspase-9 and annexin-5) were measured by immunoenzyme method (ELISA). Results. The activation of signal apoptosis systems in infants with AD with increased levels of sFas-L и sCD153 was revealed. Levels of caspase-8 and caspase-9 were significantly lower than in control group, and reflected the impaired elimination of modified immmunocompetent cells. The level of annexin-5 was significantly lower in infants with AD than in control group. The estimation of the dynamics of investigated parameters during diet therapy showed significant increase of caspase-9 level in both groups. The level of caspase-8 was increased only in infants who were fed by goat milk formula. Levels of sFas-L, sCD153 and annexin-5 during diet treatment did not differ significantly between groups. Conclusion. The results showed that sCD153, caspase-8, sFas-L, caspase-9 and annexin-5 play a role in the realization of allergic inflammation in infants with AD. The diet therapy with goat milk formula promotes more physiological repair of the effectory component of the apoptosis.

Industrial high-pressure processing (HPP) was conducted on cow and goat milk in comparison to conventional heat pasteurization. No significant changes were found in the physico-chemical properties of the treated milk except for pH, where pasteurized cow milk experienced a decrease while goat milk’s pH increased for both pasteurized and HPP treated. HPP-treated cow and goat milk both achieved microbial shelf life of 22 days at 8 °C storage with no increase in Bacillus cereus, mesophilic aerobic spores, coliform, yeast and mold but slight increase in psychrotrophic bacteria and total plate count. Pasteurized goat milk was spoilt at the end of storage with exceeding count of psychrotrophic bacteria (9.0 × 108 CFU/mL) and total plate count (3.5 × 108 CFU/mL). HPP-treated cow milk exhibited higher physico-chemical stability than goat milk as evidenced by non-significant change of titratable acidity but goat milk experienced an increase of 0.04% averagely.
