In order to research the quality-change of Ready-to-eat sea cucumbers in the storage period. The Ready-to-eat sea cucumbers were respectively stored under 5, 10 and 15 °C to determine the sensory quality and textural property. The results showed that: During the storage period, the quality of the Ready-to-eat sea cucumbers decreased gradually. When the sense of the samples declined to the acceptability limit, the smell and the surface viscosity changed significantly. The value of hardness, elasticity, cohesiveness and chewiness were determined the sensory acceptable limit at different stored temperature.

The aim of this work was to monitor quantitative and qualitative representation of probiotic strain L. casei 01 (Sacco, Italy) in dry femented sausages „Herkules“ taken from two different producers (A and B). Negative control susages without probiotics were also made at both producers, to monitor the differences between pH profiles of and lactic acid bacteria counts during fermentation and sto­ra­ge of dry sausages. The second objective of this study was to determine sensory quality of probiotic sausages in comparison with non-probiotic controls.The counts of L. casei and LAB in all sausages significantly (P < 0,01) increased during fermentation and storage period. Probiotic L. casei was well adapted to dry sausages environment and reached 106 CFU/g in both producers. No differences between pH profiles of probiotic sausages and controls without probiotics were observed.It was observed that all probiotic sausages had sensory properties near the traditional products.

The effect of packaging in nitrogen (N2) atmosphere or in air on the quality of peeled and roasted almond var. Guara during storage for 20 weeks at 20 °C ± 1 °C and 65–70% relative humidity (RH) was studied. No changes in the sugar, fat, protein or fiber contents were observed during the storage period nor in color. Only the lipid fraction showed significant changes with the kind of packaging atmosphere. The composition of fatty acids remained unchanged during the 5 month storage in all the samples. Packaging in N2 atmosphere was seen to have a protective effect against the accumulation of conjugated dienes (CD) in peeled almonds, while in roasted almonds, the protective effect was lower and even nil by the end of storage. The contrary effect was observed for the ultraviolet (UV; K270) index which increased more slowly in the roasted samples packaged in N2, while in peeled samples it reached the same levels at the end of storage regardless of the packaging atmosphere. No effect of the packaging atmosphere was observed on the evolution of the peroxide value in the tested samples (peeled or roasted almonds). None of these changes in the lipid fraction was reflected in the final sensory quality of the samples and the taster panel found no changes in the sensory quality in any case.

The aim of the study was to examine whether immobilization of Bifidobacterium infantis inside hydrogels could prolong their survival in fermented milkless beverages. The starter culture Streptococcus thermophilus was used to obtain fermented nonmilk beverages: oat, oat-banana, and oat-peach. The biota of beverages were supplemented with Bifidobacterium infantis cells, free and immobilized, in three types of spherical hydrogel particles: microcapsules with a liquid and gelled core, microbeads of 0.5 mm diameter, and beads of 2.5 mm diameter. As a carrier material, low-methoxylated pectin and alginate were used. Microbeads and microcapsules were obtained using extrusion techniques: vibrating and electrostatic method, and beads were obtained using manual method with a syringe. A significantly lower decrease in the count of cells immobilized in hydrogels compared to free cells was observed during storage of fermented beverages at 4°C. Microcapsules were more effective compared to microbeads in terms of bacterial cells protection. The observed effect was better for higher biopolymer concentration. The highest survival of the strain was noted in cells immobilized in low-methoxylated pectin beads of 2.5 mm diameter. Supplementing the biota of fermented beverages with microencapsulated bacteria did not negatively affect the overall sensory quality of beverages during the entire storage period.

The aim of this study was to examine the changes of nutritional and sensory quality of sprouted alfalfa seed treated by high pressure, that take place during storage. Along with this, microbiological safety was also observed. Sprouted alfalfa seed in citric acid pickle, packed in transparent laminated bags PA/PE 80, was treated with 500 MPa high pressure for 10 minutes. The processed seed in bags was stored in a refrigerator for 21 days. The bags were sampled in regular intervals to perform analyses. The changes in the contents of vitamin C, riboflavin, niacin, and pantothenic acid were observed during storage. The same samples were also checked for microbiological safety and sensory quality. Vitamin C showed a significant decrease during storage. The content of vitamin C fell markedly after high pressure treatment (by 77%) and further decreased by 10&ndash;20% during storage. The values of riboflavin content did not change very much as a consequence of pressurisation or the storage period. The contents of niacin and pantothenic acid kept decreasing until the 3<sup>rd</sup> day of storage by some 60% in total and then remained unchanged. Sensory descriptors indicated quality decrease. High pressure treatment damaged the tissues of sprouted alfalfa seed which subsequently manifested itself particularly in the deterioration of appearance and texture quality. An additional overall impairment of the seed appearance and texture occurred during its storage. Microbiological safety of sprouted alfalfa seed was preserved throughout the storage time. &nbsp;

Chinese rolls are prepared from hot water dough and wrapped with meat and vegetable when consumption. Staling of Chinese rolls results in loss in texture and eating quality. Moisture content, enthalpy change (H), texture and sensory quality of Chinese rolls which are significantly affected during staling at 4°C storage, were monitored over a storage period of four days. Moisture content was founded to decrease steadily during staling of Chinese rolls. Enthalpy change, H, as measured by DSC increased with storage time. The texture of Chinese rolls became progressively harder with storage at 4°C. A decrease in sensory quality and acceptability of the Chinese rolls was observed with storage. Most of the staling parameters show good correlation. Texture showed the best overall correlation with all other staling parameters.

Abstract  Cancer is the main cause of death in the world with the number of sufferers in 2008 as many as 12.7 million with a death rate of 7.6 million people. In Indonesia, it is estimated that there are more than 1 million cancer patients in 2010. One of the ways to prevent cancer is primary prevention by adjusting the pattern and type of food consumed. Functional food introduced by bioactive components from sea cucumbers is an alternative for cancer prevention. The specific objective of this research was to produce meat-based functional foods containing anti-cancer compounds derived from sea cucumbers that can prevent cancer. The preliminary tests conducted were the sea cucumber extract lethality test against Artemia salina, namely the Brine Shrimp Lethality Test (BSLT), and the total bacteria of  beef meatballs. The results of the observation of the lathality of sea cucumber extract against Artemia salina and total bacteria of the meatball showed that the sea cucumber extract had high lathality against Artemia salina and was able to reduce the total bacteria in meatballs during storage period. The lathality of sea cucumber extract was strongly influenced or stimulated by heating treatment. Based on the BSLT test, of the five types of sea cucumbers, two of them (Holothuria similis and Pearsonothuria graeffei) have high lathality. Sea cucumber extract was also able to inhibit both bacterial and fungal growth in meatballs during storage at room temperature. Keywords: Beef Meatballs, Total Bacteria, Sea Cucumber, BSLT.

Summary The aim of the study was to determine the effect of the cultivation method (organic and conventional) on the sensory quality of carrot roots - fresh, stored, and cooked. The study was conducted in the sensory evaluation laboratory of the Institute of Horticulture in Skierniewice in 2009-2011. The carrot roots came from a certified experimental field with a stable ecosystem, adapted for conducting experiments on the organic growing of vegetables. At the same time, in the same soil and climatic conditions, carrots were grown in the conventional system. The experimental material consisted of two varieties of carrot - Perfekcja and Regulska. In a two-year cycle, sensory analyses were performed of fresh carrot roots, and of roots that had been stored and heat treated. The evaluations were conducted by a 10-person panel of specialists using the method of quantitative descriptive analysis (QDA). The results of qualitative sensory evaluations and the profilograms prepared on that basis for fresh and stored carrot roots indicated differences in the sensory characteristics between the tested varieties grown in organic and conventional systems. The greatest impact on the overall quality was exerted by the attributes: the carrot-taste, sweet taste, juiciness and hardness of the flesh. Organically grown carrots of the variety Regulska were characterized by the highest intensity of sweet taste and the carrot- taste, and by the best hardness, crunchiness, crispness and juiciness of the flesh. Fresh roots of this variety received the highest overall score. There were also some differences in the sensory characteristics of carrot roots after several months of storage, and then after cooking them, depending on the variety and cultivation method. In both years of the study, following the storage period, the cooked carrot roots of the variety Perfekcja from organic cultivation received the highest scores for overall quality. After storing and subjecting carrot roots to heat treatment, there was a significant decrease in the intensity of most of the quality descriptors, such as taste, smell and texture, when compared with the fresh roots under evaluation

Abstract Structural proteins play critical roles in the food quality, especially texture properties, of sea cucumbers and their products. Most of the previous studies on sea cucumbers focused on few individual proteins, which limited our understanding of how structural proteins influenced the quality of sea cucumbers. Inspired by the clarification of sea cucumber (Apostichopus japonicus) genome, we established an integrated data of structural proteins in the sea cucumber body wall. A portfolio of 2018 structural proteins was screened out from the sea cucumber annotated proteome by bioinformatics analysis. The portfolio was divided into three divisions, including extracellular matrix proteins, muscle proteins, and proteases, and further classified into 18 categories. The presence of 472 proteins in the sea cucumber body wall was confirmed by using a proteomics approach. Moreover, comparative proteomics analysis revealed the spatial distribution heterogeneity of structural proteins in the sea cucumber body wall at a molecular scale. This study suggested that future researches on sea cucumbers could be performed from an integrated perspective, which would reshape the component map of sea cucumber and provide novel insights into the understanding of how the food quality of sea cucumber was determined on a molecular level.
