Physical, chemical, and microbiological properties of fish tofu containing shrimp hydrolysate

Lakum (Cayratia trifolia (L.) Domin) contains a lot of anthocyanin. Anthocyanin in Lakum fruit has a high stability if stored at low temperatures, acidic conditions, and without light. The acidic product such as yogurt can provide an optimum condition for anthocyanin stability and antioxidant activity. The purpose of this study was to optimize yogurt formulation fortified by lakum fruit extract as an antioxidant according to the requirements of the Indonesian National Standard (SNI). Lakum fruit extract was formulated in yogurt with various concentrations at 0%, 5%, 7.5% and 10%. Evaluations were carried out including tests of physical, chemical and microbiological properties and anthocyanin test and antioxidant of yogurt. The results showed that the yogurt formula fortified lakum fruit extract at 7.5% concentration resulted highest anthocyanin stability and antioxidant activity that fulfilled SNI requirements and the preferred level of respondents' preference with anthocyanin levels of 53.35±1.04 mg/L, antioxidant activity 69.15±0.24%, t90 7.97 days, total of lactic acid bacteria (LAB) 48.2x107 colony/gram, fat 3.72±0.03%, pH 3.87±0.03, total acid 0.83±0.06%, viscosity 639.07±2.06 cP, protein of 4.90±0.11%, hedonic test, 6.88 (like), and organoleptic purple (5), the distinctive aroma of lakum fruit (4.95), sour taste (4.85), fine texture (4.9) and slightly liquid viscosity (4.85).

Microbiological Properties

Sun-dried spanish mackerel is a common food in Dalian and made by adding salt and sun drying, which has special physical, chemical and microbiological properties. In this study, the physicochemical properties and microbial composition of the commercial available sun-dried spanish mackerel in Dalian were assessed, and some Lactobacillus strains were screened as bio-preservative for sun-dried spanish mackerel preparation. The results showed that the TVBN content in the traditional sun-dried spanish mackerel samples from Dalian was within 30 mg/100g, the histamine content was 7-17 mg/kg, and the dominant bacteria at the genus level were Lactobacillus , Psychrobacter and Ralstonia . A strain with bio-preservative potential was isolated from sun-dried spanish mackerel sample, identified as L. plantarum species by 16S rDNA sequencing, and assigned as L. plantarum X23. Fresh spanish mackerel flesh was treated with 16% brine and L. plantarum X23 at a dose of 10 7 CFU/mL, and then sun-dried. The sun-dried spanish mackerel flesh treated with 16% brine and L. plantarum X23 showed the decreased histamine and acid value, the increased free amino acids contents, and a higher sensory score, compared with the sun-dried spanish mackerel without L. plantarum X23 treatment. In conclusion, the sun-dried spanish mackerel purchased from the supermarkets in Dalian were edible safe, and L. plantarum X23 can significantly reduce the content of histamine and putrescine in the self-made low-salt sun-dried spanish mackerel, and has the potential to be as bio-preservative for sun-dried spanish mackerel preparation.

Effects of soil attributes using the geostatistical tool improves the interpretation of specific soil management. Thus, this study aimed to evaluate the physical, chemical, and microbiological properties of a Typical Haplustox (Oxisol), identifying those with the best linear and spatial correlation with eucalyptus (Eucalyptus spp.) vegetative growth. The experiment was conducted at the Teaching, Research, and Extension Farm (FEPE) of the Universidade Estadual Paulista (UNESP), Campus of Ilha Solteira. Thirty-five points spaced 13 meters apart were demarcated for analysis, which were distributed in 5 rows of 7 points each. From each point, 2 soil samples were collected from the 0-10 cm depth layer. The physical, chemical, and microbiological soil properties evaluated were: sand, silt, and clay contents; penetration resistance (PR), gravimetric moisture (GM), real density (RD), microbial biomass carbon (MBC), respirometry (CO2-C), metabolic quotient (qCO2), organic matter content (OM), and hydrogenionic potential (pH). The eucalyptus attributes assessed were: plant height (PH) and circumference at breast height (CBH). Each attribute was analyzed by descriptive statistics using the SAS software. Data frequency distribution was verified by the Shapiro Wilk method, and geospatial changes were analyzed by the GS+ software. The soil property that best explained the variability in eucalyptus dendrometric attributes was real density (RD). Except for RD, all properties did not show spatial dependence (i.e., pure nugget effect), which significantly represents eucalyptus vegetative performance.
