<p>The proteic hydrolysis is a technology developed with the aim of adding value, functionality and increase the use of undervalued raw materials. Through this process is possible to modify the chemical, physical and biological properties of proteins without changing their nutrient content. This study aimed to develop proteic hydrolyzed of Nile tilapia &ldquo;V&rdquo; cuts and to characterize them according to their degree of hydrolysis, chemical composition and microbiology. The results of analyses showed that the developed hydrolyzed had high productivity and appropriate degree of hydrolysis (14.8 % to H1 and 13.2 % to H2) that allow to use them both in the treatment of diseases as a flavoring in foods. In addition to presenting good composition, similar to the initial raw material, with 81.4 and 81.0 % for moisture, 13.6 and 14.6 % for protein, 3.5 and 2.8 % for lipids and 2.7 and 2.0 % for ash, respectively for H1 and H2. With relation to microbiological results, the hydrolyzed showed great health quality, well below the limits allowed by law. Therefore, the enzymatic hydrolysis proved to be an efficient process to obtain hydrolyzed proteins from a high biological value and low value raw material.</p><p>&nbsp;</p><p>DOI: <a href="http://dx.doi.org/10.14685/rebrapa.v4i1.97">http://dx.doi.org/<span>10.14685/rebrapa.v4i1.97</span></a></p>

Sherry wine vinegar is a Spanish gourmet product under Protected Designation of Origin (PDO). Before a vinegar can be labeled as Sherry vinegar, the product must meet certain requirements as established by its PDO, which, in this case, means that it has been produced following the traditional solera and criadera ageing system. The quality of the vinegar is determined by many factors such as the raw material, the acetification process or the aging system. For this reason, mainly producers, but also consumers, would benefit from the employment of effective analytical tools that allow precisely determining the origin and quality of vinegar. In the present study, a total of 48 Sherry vinegar samples manufactured from three different starting wines (Palomino Fino, Moscatel, and Pedro Ximénez wine) were analyzed by Fourier-transform infrared (FT-IR) spectroscopy. The spectroscopic data were combined with unsupervised exploratory techniques such as hierarchical cluster analysis (HCA) and principal component analysis (PCA), as well as other nonparametric supervised techniques, namely, support vector machine (SVM) and random forest (RF), for the characterization of the samples. The HCA and PCA results present a clear grouping trend of the vinegar samples according to their raw materials. SVM in combination with leave-one-out cross-validation (LOOCV) successfully classified 100% of the samples, according to the type of wine used for their production. The RF method allowed selecting the most important variables to develop the characteristic fingerprint (“spectralprint”) of the vinegar samples according to their starting wine. Furthermore, the RF model reached 100% accuracy for both LOOCV and out-of-bag (OOB) sets.

Shrimp Shell Waste

Feed is still one of the problems in aquaculture because it takes about 70% of operational costs. High prices is caused by imported raw materials for feed production. One possible effort to overcome this problem is to find alternative local raw materials to replace imported fish meal. The purpose of this study was to examine the proximate content of shrimp shell wastes from processing shrimp crackers (Paneus sp.) to be used as shrimp flour. Samples were colledted three times in a month, at the beginning, middle and end of the month. The waste of the heads, shells and tails of the shrimp were turned into flour for laboratory testing through proximate analysis. The data were tabulated using the Microsoft Excel softwareand then analyzed descriptively by comparing the nutrient content of shrimp waste flour with the feed requirements of mariculture. The results showed that shrimp shell flour contained protein, fat, carbohydrates and ash content of around 27.4%, 2.07%, 14.84% and 47.27%. while the resulting randemen ranged from 81.75%. Therefore, shrimp shell flour can be used as an alternative raw material for preparing marine fish feed.

Many sources of raw materials which allegedly can enrich the nutrient content in the organic fertilizer. The weakness of organic fertilizer for this is the low level of nutrients contained in them.This study aims to determine the nutrient content contained in various combinations of organic fertilizer raw materials with rabbit animal waste as the main raw material.This study aims to determine the nutrient content in various combinations of organic fertilizer raw materials with rabbit animal waste as the main raw material. The experiment used a completely randomized design with raw materials as treatments, Livestock Waste Rabbit (LTK), Cow Manure (PKS) and Abu Straw Rice (AJP). Such treatment: B1 = LTK; B2 = LTK: PKS = 2: 1; B3 = LTK: AJP = 3: 1; B4 = LTK: PKS: AJP = 6: 2: 1; B5 = LTK: PKS: AJP = 5: 2: 1; B6 = LTK: PKS: AJP = 4: 2: 1; B7 = LTK: PKS: AJP = 3: 2: 1; B8 = LTK: PKS: AJP = 2: 2: 1; B9 = LTK: PKS: AJP = 1: 2: 1. The research concluded (a) Organic fertilizers are made from various materials raw has fulfilled SNI 19-7030-2004 about the specifications of Organic Waste Compost. (B) A combination of organic fertilizer raw materials significantly affect the nutrient content of manure. (C) Organic fertilizers expectations are: (a) Raw materials of animal wastes rabbit (LTK), (b) LTK: PKS: AJP = 6: 2: 1, (c) LTK: PKS: AJP = 2: 2: 1 and (d) LTK: PKS: AJP = 1: 2: 1.
