In the Jam Industry, Inline Refractometers Play an Important Role.

Quality control during production
1. Monitoring soluble solids

• During the jam-making process, sugars and other substances in the fruit dissolve in water to form soluble solids. Inline refractometers can accurately measure the soluble solids content in the jam in real time. By monitoring this indicator, it is possible to ensure that the sweetness and taste of the jam meet the expected standards. For example, for strawberry jam, the right soluble solids content can make the jam have a strong strawberry flavor and just the right sweetness without being too sweet or thin.
• During the production process, according to the requirements of different types of jam, processing parameters such as heating time and stirring speed can be adjusted at any time to ensure that the soluble solids content is stable within the optimal range.

2. Ensure product consistency

• The continuous monitoring function of inline refractometers helps to ensure the quality consistency of different batches of jam. Whether it is large-scale production or small batch production, the soluble solids content, concentration and other key indicators of each batch of jam can be kept relatively stable through accurate measurement by the refractometer. This is crucial for establishing a brand image and meeting consumers’ expectations for product quality stability. For example, for a well-known blueberry jam brand, consumers can experience the same rich blueberry flavor and mellow taste when purchasing different batches of products. This is inseparable from the strict control of the production process by inline refractometers.

Optimize production process

1. Precisely control the cooking process

• The cooking process of jam is one of the key links that determine its quality. Inline refractometers can provide real-time feedback on the concentration changes of jam during the cooking process, helping operators to accurately judge the degree of cooking. When the soluble solids content reaches the predetermined target, stop cooking in time to avoid overcooking that causes the jam to burn or lose nutrients, while also saving energy and time. For example, during the cooking process of apple jam, the operator can stop heating at the best time according to the reading of the refractometer to keep the apple jam in the best color, taste and nutrients.
• Through the precise control of inline refractometers, the cooking process of different types of jam can be standardized, and production efficiency and product quality can be improved.

2. Adjust the proportion of raw materials

• In jam production, it is sometimes necessary to adjust the proportion of raw materials according to factors such as the maturity and sweetness of different fruits. Inline refractometers can quickly measure the soluble solids content of jam at different raw material ratios during the production process, providing a scientific basis for adjusting the raw material ratio. For example, when using sweeter fruits to make jam, the amount of sugar added can be appropriately reduced, and the soluble solids content of the adjusted jam can be monitored by a refractometer to ensure that the taste and quality of the jam are not affected.

Product inspection and quality assurance
1. Finished product inspection

• After the jam is produced, Inline refractometers can quickly test the finished product to ensure that the product meets the quality standards. If the soluble solids content is found to be not up to standard, it can be adjusted or processed in time to prevent unqualified products from entering the market. For example, for a batch of orange jams that are about to be shipped, the soluble solids content is found to be low through the test of Inline refractometers. It can be adjusted by re-cooking or adding an appropriate amount of concentrated juice to ensure that the product quality meets the standard.
• The rapid detection function of Inline refractometers can greatly improve the efficiency of product inspection, reduce the error of manual inspection, and provide strong support for the quality assurance of jam.

2. Quality traceability

• The data recording function of Inline refractometers can provide an important basis for the quality traceability of jam. During the production process, the data such as the soluble solids content recorded by the refractometer can be associated with the production batch, time and other information. Once a quality problem occurs, these data can be quickly traced back to the problem link and corresponding measures can be taken to rectify it. For example, if consumers report that a batch of jam tastes abnormal, the company can query the historical data of the refractometer to analyze possible problems in the production process, such as raw material quality and processing technology, so as to make targeted improvements and improve product quality and safety.
