Short communication: Influence of long-chain inulin and Lactobacillus paracasei subspecies paracasei on the sensory profile and acceptance of a traditional yogurt

Tatiana Colombo Pimentel; Adriano G. Cruz; S.H. Prudencio

The objectives of this study were to evaluate the influence of the addition of long-chain inulin as a fat replacer and prebiotic agent (20g/L) and (or) probiotic Lactobacillus paracasei ssp. paracasei on the sensory profile and acceptance of yogurts, and to assess the influence of descriptive attributes on the sensory acceptance of the products. The addition of inulin to low-fat yogurt improved its brightness and firmness, which was similar to the full-fat yogurt. However, the use of long-chain inulin increased the separation of serum and no influence on creaminess was observed. Regarding the products acceptability, the low-fat yogurt with added inulin presented similar acceptance compared with the full-fat yogurt. The addition of Lb. paracasei ssp. paracasei did not affect the sensory profile and acceptance of the low-fat yogurt. Using external preference mapping, it was possible to verify that the sensory acceptance was driven positively by the sweetness and creaminess and negatively driven by firmness (appearance and texture) and homogeneity (appearance). It was possible to formulate low-fat yogurts with added probiotics that presented similar sensory characteristics to those of full-fat yogurts, and this was due to the addition of the long-chain inulin as a fat replacer.

This study aimed to evaluate the effect of oil content reduction and the addition of inulin as a partial oil substitute on the physicochemical, microbiological, and textural characteristics and acceptability during the storage (4 °C for 45 days) of dry-fermented chicken sausage produced with corn oil. Reducing the oil content did not influence the characteristics evaluated but tended to produce sausage with a dark reddish coloration. The addition of inulin did not change the physicochemical and microbiological parameters or the acceptability of the products, but resulted in an altered texture profile and a tendency toward lighter and less reddish coloration, similar to products with standard oil content. Fermented chicken sausages produced with standard amounts of corn oil, reduced amounts of corn oil, and inulin as a partial oil replacement remained stable without a significant loss of physical, chemical, microbiological, or sensory attributes during storage at 4 °C for 45 days.

Flávia Daiana Montanuci; Tatiana Colombo Pimentel; Sandra Garcia; Sandra Helena Prudencio

The effect of inulin addition and starters (Kefir grains or commercial starter culture) on the microbial viability, texture, and chemical characteristics of Kefir beverages prepared with whole or skim milk was evaluated during refrigerated storage. The type of starter did not influence microbial viability during the storage of the beverages, but the chemical and textural changes (decreases in pH, lactose concentration, and inulin and increased acidity, firmness, and syneresis) were more pronounced in the formulations fermented with grains than those fermented with the starter culture. The addition of inulin did not influence acidity or viability of lactic acid bacteria, but in general, its effect on the survival of acetic acid bacteria, Lactococcus and yeasts, firmness, and syneresis depended on the type of milk and starter culture used. Generally, the yeast, acetic acid bacteria, and Leuconostoc counts increased or remained unchanged, while the total population of lactic acid bacteria and Lactococcus were either reduced by 1 to 2 logs or remained unchanged during storage.

Senaka Ranadheera; Lana de Souza Rosa; Anderson Junger Teodoro; Simone Pereira Mathias; Marcia C. Silva; Renata S.L. Raices; Silvia Magalhães Couto; Daniel Granato; Adriano G. Cruz

The effects of the concentration of watermelon juice at different temperatures (45, 55, or 65 °C) on the physicochemical and sensory characteristics, antioxidant capacity, and volatile organic compounds (VOCs) of whey-based popsicles were investigated. Total phenolic content, lycopene, citrulline, VOCs, melting rate, instrumental colour, antioxidant capacity, and the sensory characteristics (hedonic test and free listing) were determined. The temperature led to a significant decrease in bioactive compounds (total phenolics, lycopene, and citrulline). The popsicle manufactured with reconstituted watermelon juice concentrated to 60 °Brix at 65 °C presented higher antioxidant capacity and was characterized by the presence of alcohols, aldehydes and ketones and presented a similar acceptance to the untreated popsicle (except for flavour). It is possible to combine whey and concentrated watermelon juice for the manufacture of bioactive-rich popsicles, using the concentration temperature of 65 °C as a suitable processing condition for potential industrial applications.

Probiotic Food Development: An Updated Review Based on Technological Advancement

Daniel Granato; Filomena Nazzaro; Tatiana Colombo Pimentel; Erick A. Esmerino; Adriano Gomes da Cruz

Fermented dairy products, such as yogurt, fermented milk, and fermented whey beverages, comprise most of the food containing probiotic cultures. However, consumers are now looking for cholesterol-free and animal-based-free foods because of nutritional restrictions (i.e., lactose intolerance or high total cholesterol), philosophy (i.e., veganism or vegetarianism) and/or taste requirements. This technological trend is expanding and food companies are investing in developing nondairy alternatives of probiotic foods, such as meats, juices, jams, granolas, dried fruit slices, and other vegetable-based products. In this review, we focused on the latest development of probiotic foods (dairy and nondairy products), giving emphasis on technological aspects.

Purpose The purpose of this study was to evaluate beet and orange mixed juices added with lyophilized Lactobacillus acidophilus probiotic culture. Design/methodology/approach Two formulations of probiotic beet and orange mixed juices (1:1 e 1:2 v/v) were prepared, stored at 4°C for 28 days and were evaluated for probiotic survival, physicochemical stability, antioxidant activity and sensory acceptance. The probiotic culture was added in a lyophilized form and was not propagated in culture media or juice. Findings Physicochemical characteristics (pH, titratable acidity, total soluble solids and color) and antioxidant activity showed no undesirable alterations during storage. The number of probiotics followed established minimum requirement for probiotic foods (109 CFU/200mL) during the 28 days of storage. The juices showed good sensory acceptance and purchase intention, especially regarding the color of the product. Practical implications The beet and orange mixed juices are suitable carriers for L. acidophilus with a shelf life of at least 28 days at 4°C. Originality/value Direct addition of the probiotic culture could result in high probiotic survival in mixed juices, dispensing the propagation step.

Probiotic yoghurt with inulin-type fructans of different degrees of polymerization: physicochemical and microbiological characteristics and storage stability

Tatiana Colombo Pimentel; Sandra Garcia; Sandra Helena Prudencio

The effect of the addition of inulin-type fructans of different degrees of polymerization (DP) on the physicochemical and microbiological characteristics and storage stability (4°C for 28 days) of nonfat probiotic yoghurt was investigated. The yoghurts were prepared using traditional lactic culture (Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and Lactobacillus paracasei ssp. paracasei as probiotic. The formulations contained inulin- type fructans of DP: low (P95 oligofructose, DP 5), medium (ST inulin, DP 10) or high (HP inulin, DP 23) in a concentration of 2g 1

ABSTRACT Consumers are very interested in the development of new food products, which presents sensorial, nutritional, and physicochemical quality. Thus, this study aimed to evaluate the addition of chia seed mucilage as an emulsifier substitute on the physical and chemical characteristics and on acceptance of chocolate-flavored prebiotic ice cream (with inulin). The ice creams had good physicochemical characteristics: The sample with the lowest mucilage content (0.6 g/100 g) showed higher resistance to melting, however, showed less overrun. Ice creams with higher concentrations of mucilage (1.2 or 1.8 g/100 g) had higher overrun. All ice creams had scores between 6 and 7 in the evaluated attributes, indicating that consumers liked slightly to moderately. The fatty acid composition of the mucilage was predominantly polyunsaturated fatty acids. It can be concluded that it is possible to develop prebiotic ice cream with chia seed mucilage as an emulsifier that have appropriate chemical composition and acceptance.

Senaka Ranadheera; F.O. Borges; Thatyane Vidal Fonteles; Roberto Pinto Cucinelli Neto; Maria Inês Bruno Tavares; Fabiano A.N. Fernandes; Sueli Rodrigues; Adriano G. Cruz

The present study aimed to compare the physicochemical (pH), physical (rheology parameters and particle size), microstructure (optical microscopy) and thermal properties (differential scanning calorimetry) of guava flavored whey-beverages submitted to cold plama technology in different processing time (5, 10, and 15 min) and gas flow (10, 20, and 30 mL min-1) conditions with a conventional pasteurized product. Whey beverages treated by cold plasma presented higher pH values, lower consistency and lower viscosity, and a flow behavior index similar to Newtonian fluids. Milder cold plasma conditions resulted in whey beverages with higher pH, lower viscosity and consistency, and similar particle distribution and microstructure compared to the pasteurized product. In contrast, more severe processing conditions resulted in a higher particle surface area ([D 3,2]) and smaller particles (~10 μM), due to the decrease in the number of larger particles (1000 μM), cell rupture, the formation of cell fragments, and higher viscosity and consistency. The treatments did not affect the thermal properties (enthalpy and bound water) of any sample.
